Leaving the door to the classroom ajar to allow the warm September breeze to flow through the classroom from one of the open windows, Professor Marion Burbage has set up a table next to the door with rows of Muggle soda bottles of various flavors lined up along with empty plastic cups. The professor is currently seated and looking over two photographs that you cannot make out just what of in the front of the classroom.
Beside the display of two-liter pop bottles is a seating chart of the classroom and a note that reads:

Taylor cleaned up her area and sat her bottle rocket on the corner of the desk. Tay listened, interested as she explain the rockets. She smiled and thought about the two questions on the board. After a while she raised her hand, "Professor the greater the thruster the faster your rocket will go fits with Newton's second law, right? The thrust is the force, the water and bottle is the mass..." Tay gestured, "Or am I totally wrong?" She started to blush in embarassment.

Lex listened carefully to what the Professor had just said. For the most part she was just nodding and smiling because she was told that that was the best thing to do when someone was speaking and you didn't have a clue what they were going on about, which was certainly the case right now.
Occasionally her eyes would shift to her rocket. While she listened she was thinking about how cool it would be when she actually launched it! It would probably shoot up really high--LE GASP!!! If it did that then she might never see it again and if she did it would probably be in a million, bajillion pieces or something. As the Professor continued Lex picked up the rocket and clung tightly to it...she didn't wanna blow him up...he was just a baby...no more than a couple minutes old...sniffle...they had been through so much together--she nearly lost a limb creating him!!
Why did the world have to be so cruel to make-shift rockets?!
Through her new found panic she managed to listen to the rest of the Professor's instructions and actually found that her interest had been peaked when they were told to pick a statement and see which law it fit.
Her eyes drifted from the statement to her notes then back to the statement.
Stare.
STARE.
Then suddenly it hit her. Without thinking she blurted in her excitement. "Professor, this may shock you but I think I know the answer this time!" Well not really an answer...just her input on the whole statement thingy. She began pointing to the board with it's statements. "That second statement...it has to do with that proportionality law thing that that guy ripped off from nature...right?" That had to be it, because the idea already hit her in her head and now she was having a minor headache.

Alyssa listened as the Professor started speaking and as she continued to speak, Alyssa's eyes started blurring over. Whatever the Professor was saying, even though she was so eloquent in what she was saying, sounded like greek to her.
So Alyssa started to write down what she was saying in the hope that by reading what she had said, she might eventually understand what she was trying to say.
Text Cut: Trying to figure out whatever was said
Newton's laws of motion
Law 1. The Law of Inertia:
"An object at rest tends to stay at rest and an object in motion tends to stay in motion."
Law 2. The Law of Proportionality:
"The acceleration of an object is directly proportional to the net force and inversely proportional to its mass.” This can be expressed in equation form:
Force = (Mass) x (Acceleration)"
Law 3. The Law of Action-Reaction:
"For every action there is an equal and opposite reaction."
My own notes:
Rockets will be using water as the its fuel. In order for the water to be able to push the rocket up, we need to add thrust to it which has to be greater than the weight of the rocket.
Cannot use too much water or it will not launch because water is heavier than air. But just using air alone will not launch our rocket either.
As Alyssa read she finally figured out what the Professor was trying to say. They had to find a proper balance with the amount of air and water used, in order to get the best result they wanted.
Now Alyssa looked at the statement the Professor had written and then back at Newton's Law Of Motions.
Quote:
Rockets create thrust by expelling a propellant (water in our case)
The greater the thrust the faster your rocket will go
Looking back and forth at the statement and then at the the Laws of Motion. Alyssa made her decision. She raised her hand and said. "Professor I believe that the statement applies to Newton's 2nd Law of Motion. The Law of Proportionality."
"If we come up with a perfect balance between how much air and water to use, our rockets will fly the way we want it to. However, if we use too little or too much of either propellant or thrust, the rocket may not launch at all. So we have to actually make sure that our calculations are accurate."
Alyssa hoped that she was making sense. Her head was starting to hurt again.

SIIIIIIIIIIIMPLY charming.
She looked at her watch and then at the progress of all her students and decided that it was about time to move things along.
Clapping her hands loudly to get everyone's attention, Marion made he way back to the front of the room holding her marigold colored bottle rocket under her arm. "DARLINGS! If you could please clean up your spaces now and set your rockets to the side for the time being, please. There is one more important matter we need to discuss before we move outside."
Suuuuuuuuuuurely they did not think that they were going to launch these inside, right? Silly little children. Ho ho ho ho!
"Now, if you could all please look at the board or refer to your notes on Newton's laws of motion," she said as she tapped her wand against the board.
"Without understanding these laws, mankind would have neeeeeeever been able to launch aaaaaaanything into space. Not satellites. Not monkies. Not humans. And ceeeeeertainly not rockets, which is why we are studying them. It is because of our understanding of these that all that was made possible and the field of astronomy was able to rise to new heights." She picked up her bottle rocket and held it up for the class to see. "Your rockets will be using water as its 'fuel' source. Meaning that water shall be the propellant that comes out of the nozzle here and shooooooots it up into the air when we pump air into it. In order to accomplish this, you will need to produce enough thrust. This muuuuuuuuust be greater than the weight of your rocket. For example, say this rocket here weighs 10 pounds," which it didn't, but that was not the point. "An upwards thrust of 10 pounds would keep your rocket stationary and at a constant level. 12 pounds of it wouldn't launch your rocket very high, but the trust would be greated than the weight of this rocket so it wooooooould move."
She paused for a moment tapped her bottle with her wand, filling it about 1/3 of the way with water. "Some of you may wonder why we cannot just use air to launch our rockets. The answer is rather simple darlings. Water is almost 800 times more dense than air. So, when your bottle rockets expel water, they will be expelling total mass and this increased mass results in increased rocket performance!" She paused for a moment so that students could write down any notes they wish. "Noooooow, some of you may be thinking, BUT PROFESSOR!? WHY DIDN'T YOU FILL YOUR ROCKET ALL THE WAY WITH WATER?! Tooooooo much water will cause your bottle rocket to be toooooo heavy and therefore hinder its flight. Too much of a good thing can be bad darlings."
But she was somewhat getting ahead of herself here. Oops. "Please keep all this in mind as you think over the following statements please, darlings." And she gave her wand a flick towards the board again.
She then turned to face the class, her smile as wiiiiiiiiiiiiide as can be. "Please select ONE of these statements and think about which of Newton's laws of motion best fits the statement. You may discuss among your classmates or siiiiiiiiiiiimply think on your own. You may share your thoughts whenever you are ready. We will just discuss this for a feeeeeeeeeew minutes and then head outside."

After Professor Burbage had tapped the board with her wand, Kat immediately got her copy of notes on Newton's awkward Laws of Motion.
SPOILER!!: Parchment with 'em notes
Katrina Marie Hudson. Fourth Year. Slytherin.
Newton's laws of motion
Law 1. The Law of Inertia:
“An object at rest tends to stay at rest and an object in motion tends to stay in motion.”
Law 2. The Law of Proportionality:
“The acceleration of an object is directly proportional to the net force and inversely proportional to its mass.” This can be expressed in equation form: Force = (Mass) x (Acceleration)
Law 3. The Law of Action-Reaction:
“For every action there is an equal and opposite reaction.”
Picking between the choices on the other side of the board was the tricky part. Kat was kinda confused with the laws. But she tried her best to pick the best answer. She pondered well... She couldn't choose between the second law and the third law. Muggles and their complex thinking. Then she noticed both of the statements had a connection. "I think both of the statements have a connection with each other."
"Probably it would be the second law for the second statement," Kat made a not-so-sure answer since it kinda fits the statement for the 'thrust' thingy. "The force being exerted in the thrust can be affected by the mass of the bottle or water. And the acceleration... well, it's going to be how fast the rocket will go."
Ok, now Kat isn't so sure... Great.

As the Professor instructed, Jory started to clear his desk up, carefully placing his rocket to the side.
Now, back to the lesson. Jory read the new statement on the board and re-read the Laws. The boy pondered a great deal on everything before picking the Law he thought was most fitting to the statement. When he thought he had an answer, he raised his hand.
"Professor,'' Jory began. "I think Law three- For every action there is an equal and opposite reaction best explains the statement because the action done would be a great thrust and the reaction generated would be the rocket going faster.'' That's how he saw it, an equal reaction. Like the Law of Demand and Supply in Economics.
After cleaning up her desk and putting her bottle rocket to the side of the desk, Sophie flipped the parchment over to see her first notes about the Laws and whatnot.
She glanced up at the board and her eyes focused on the second statement. That sounded simpler than the first one to relate with one of those Three Laws. The rocket making thing made Sophie's mood get a little better, and she actually raised her hand to speak this time. "Professor, I think the second statement is related to the second Law." She scratched her head as she looked down at her notes again. "Because... it says this thing about the rocket's speed. And here..." She pointed at the parchment. "...it says something about acceleration."
So... it made sense, right?

Elliot disliked science. Like, a lot. So it was weird that she was taking Astronomy. Eh...
She listened to everyone...trying to grasp it...it wasn't too difficult. When Soapy began to speak, Elliot rolled her eyes and withheld a snort...honestly...Puffers. Enough SAID.
She raised her hand, feebly, but she raised it all the same. "I agree with Sophie on this one..." the first and LAST TIME Elliot would EVER utter those dreaded words again. "because...well...wouldn't the water be considered the net force...and then, since that is directly related to the acceleration, this would make the acceleration increase, like you said, right?" But then...that meant that the mass was INDIRECT with the acceleration...which kind of confused Elliot. She just needed a bit more time to think this through...she could get it eventually.
If she wanted to.

Orr nodded as she listened to the professor talking.
She read the two statements twice before choosing the second statement
Text Cut: board
The greater the thrust the faster your rocket will go
And then she looked at the three laws of Newton still on the board, which one suits the second statement best and will explain it? she thought. The first couldn't be applied because while Orr was certain that it was valid--it wasn't relevant for the purpose of their bottle rockets. The other two were much more relevant but which one? She took another look at the board
Text Cut: board
Newton's laws of motion
Law 2. The Law of Proportionality:
“The acceleration of an object is directly proportional to the net force and inversely proportional to its mass.” This can be expressed in equation form:
Force = (Mass) x (Acceleration)
Law 3. The Law of Action-Reaction:
“For every action there is an equal and opposite reaction.”
Law 3 seemed to be very relevant but as Orr thought about it-- it didn't make sense because adding water to the bottle rocket would only be one action and she wasn't sure that there was a second reaction that would be opposite to the thrust of the water.
Law 2 seem to Orr to be the most relevant and best suited to their water-thrusted bottle water but there needed to be some tweaking done to the formula because from the Professor's explanation- the water wasn't the mass of the bottle since then it wouldn't be able to move--it was the trust but there was no mention of trust in the formula so now what?
She raised her hand, "Um, Professor Burbage- I think that Law 2 might be the most suited to the second statement because the other two while valid don't seem to be relevant to our bottle rockets. I mean according to Law 1- in this state- the bottle as is won't be moving anywhere and I doubt that it would start moving as we add the water. Law 3 is valid but besides the thrust of the water what would be the opposite reaction?
Now that lies law 2 which talks about acceleration but there is no mention of thrust in it so I'm a bit confused."

SPOILER!!: Sutton Finishing Rocket Incase it can Still Count for Points
Now that all of the soda was gone, Sutton flipped through her charms book, found Scourgify, and, mimicking precisely the wand movements, cleaned out the remaining droplets of orange. With that done, she flipped the pages in her book again to find Diffindo. This spell would be a bit more difficult because it required a steady hand, almost as if cutting with an Exacto knife... except... she'd have to use her wand.
Lining up her wand with the lines drawn on the cardboard, she spoke the incantation, "Diffindo!" and began to cut as precisely as she could. Her hands were slightly shaky, though, and part way through her first hypotenuse, her hand slipped, destroying the straight edge needed for the best aerodynamics. With a sigh of frustration, she pulled her spell book toward her, searching through it for something that could fix the damage. She didn't see anything that could fix such a small area, though, and in the end, Sutton pointed her wand at the cardboard saying, "Reparo!" and she had to start cutting all over again.
Finally finishing her fins, she moved on and cut 1/3 of the bottle away from the bottom of it, then began cutting 8 small slits in her plastic bag to string the dental floss through. The problem still remained, however, that the parachute would have to be weighted by something in order to function properly. Looking at the materials she had available, she tried to figure out how she might create such a weight. Leaning forward on her desk to think, she knocked over her now empty plastic cup and was struck by a sudden idea.
Pressing the cup down on the remaining cardboard, she traced a circle and then cut the circle out using Diffindo again. Reaching down into her bag, she searched for materials that might help give some weight to the parachute and came out with a large pink Muggle eraser, a few wizarding coins, and a travel-size bottle of tooth paste. Placing the items on the cardboard circle, she then covered them with the empty cup. Pointing her wand at her make-shift weight, she said, "Adhero!" and then tested it to make sure they really were together.
Near what would have been the bottom of the cup, she cut 8 small holes on the sides and then again on the bottom. She divided her dental floss into 8 even strands, threaded each string through the corresponding holes in the cup and then through the slits in the plastic bag, tying it off at each end. Next, she moved on and attached the 4 fins equidistant around point of the bottle where it fist got wide at the top. She attached each wing with an incantation of, "Adhero!" making sure to double check the magic each time.
Once the fins were on, she stuffed the bag and weight inside the piece of the first bottle and set the whole thing on top of second bottle. She wished she had time to make a noise for it to help with the aerodynamics, but before she could even begin to think of how to design it out of the remaining materials, she heard the Professor calling for them to move on.
After making more notes of what Professor Burbage said, Sutton thought carefully about her response. Surely, she could make an argument for either statement with any of the laws. All of Newton's laws were interconnected and could not exist on their own, that much was obvious. However, she thought that perhaps she had a unique understanding of the second law. It was one of the harder ones to grasp, but it was very, VERY important to the building of such a rocket. You had to have mass to make force. That was why when you try to throw a wadded up piece of paper really hard, it doesn't work so well unless you very tightly compact the paper.
On the other hand, the First Law was imperative to understanding how and why the parachute would open. You had to grasp the effects of the First Law on objects in order to effectively use the parachute. Honestly, though, it was the combination of the first and second that reaaaaally gave you the whole picture of the parachute apparatus.
Knowing she could only talk about one of them, though, Sutton decided to go with the more difficult one. Maybe it would help some of the other kids who might be confused about it like she was when she first read it. Raising her hand, she took a deep breath and spoke up. "Professor Burbage? Okay, bear with me here. I could explain it better with paper and numbers and stuff, but I think I've got it. I think that, when considering the second statement... that the greater the thrust, the further your rocket will go, the most important of Newton's Laws is the Second."
Picking up her rocket to sort of use as a prop, she looked back up at the professor. "You see, you talked about how the amount of water affects the rocket so much, yes? Well, I think some people may be considering the mass of the water when considering the mass part of the equation, but you can't do that necessarily because that isn't a constant... the rocket loses water in flight. Basically, the water is the catalyst for the force. The mass is mass of the rocket... just as it is now. However, we can't forget that the rocket also has to battle against an opposing force... gravity."
Sutton took her rocket apart again, pulling out her weighted parachute and showing it to the professor. "And acceleration isn't just increasing in speed. I think that is a side that neither of your statements really consider. Acceleration is also a decrease in speed, and thus Newton's Second Law is equally as important in the parachute. If the parachute doesn't have enough mass to create a big enough force to match the force of thrust from launching, the parachute isn't really going to open. It might get caught in the wind, but it isn't going to work how people want it to."
Suddenly, Sutton realized how long she had been talking. It was probably more than she had said in the entire time she'd been at Hogwarts so far. The heat began creeping up her neck into her face as she turned red in embarrassment. As she hurriedly reassembled her rocket, she spoke more quietly to the professor, "Sorry.... I... lots of science fairs..." she explained apologetically before going back to sitting in embarrassed silence.

Her station all cleaned up now and her rocket lying on its side on the table, Kurumi pulled out her note parchment and began to flailing over it with her quill in a somewhat feeble attempt to keep up with everything that was being said. Kurumi was grateful for the few pauses Professor Burbage offered in her explanation, but there were so many thoughts floating around that the Gryffindor was pretty sure that her quill and hand were not keeping up with what she was hearing.
Who knew something as simple as a bottle rocket had...so much to them?
Once she felt as though she had caught up, Kurumi looked at her notes and then back at the board where the two statements were written and decided to focus on the first one. Rockets create thrust by expelling a propellant... she repeated inside her head as she looked over the laws of motion one more time.
"The first law would really only apply to a rocket once it is in space," Kurumi said mostly to herself. "Or at least out of the earth's atmosphere where there is nothing to slow it down...no air resistance..." So she could cross that one off for sure. Kurumi then found herself getting caught up in the whole thrust being mentioned in the statement and what was written for the second law. Only...something didn't really seem to fit - namely that she was somewhat struggling to wrap her head around it entirely. Not that it wasn't connected to the flight of the rocket, because it clearly was, but it just didn't seem like the best suited for that statement.
"Professor Burbage, I think that the first statement is best fitted with the third law, the law of Action-Reaction," she answered, glancing at her parchment again before looking back at the board. "The action being the propellant leaving the bottle and the reaction being the bottle's forward, or upward, movement."

Hmmm…Thoughts, discussions. Cassia leaned forward in concentration placing her elbows on her knees while the professor explained those muggle-ish .She wasn't good at those things. However, she is going to do her best and try do what the Professor wants. A quill and parchment in her hand and rested on her knee, Cassia scribbled down important points because she knew that she will forget them. At some point Cassia felt like she was listening to a foreign language, she paused and stopped writing to look at the professor. After a couple of sentences her mind started to understand again. Not so perfect but not so bad. When Professor Burbage gave them time to think ,Cassia started reading what she had just written so she could connect them to the points she had in her mind.
While processing the facts ,Cassia tapped her foot against the floor because the second-year was at her fullest level of concentration. As she wrote down her notes ,Cassia couldn't help but feeling annoyed. Why were they learning this when they could easily make the rocket fly by magic?
Finally, Cassia raised her hand and stood because she had some explaining to do and she needed to be standing. "Professor, about the second statement the one that says ;the greater the thrust the faster the rocket will go. I think that this one compatibles with Noto's seco…" She paused and glanced at her parchment, "um sorry..Newton's second law," A deep breath in, "the thrust in the statement represents the force in the equitation and the increasing speed of the rocket is the acceleration in the statement, "Stay with me woman almost there, "So when the thrust is greater the rocket is faster. Likewise when the force is great the acceleration increases." Cassia explained flailing with her hands in all directions but making sure not to take anyone's eye off with the quill she was holding. Cassia glanced at the professor questioningly..gedit studmuffins' fan?
Ok that was the best Cassia could think of and she now is feeling a bit dizzy because of thinking she just did. So can we please get back to the practical part again.

Terry cleaned up his area, throwing away the spare pieces of paper that he had spread about and took out his parchment paper notepad his mother had sent him in the owl post. He found it easier to keep all his notes together rather than writing on separate pieces of parchment. The front cover had 'Astronomy' written in large gold letters and a space themed background. He listened to the Professor start to talk and he stared at her blankly, utterly confused. Laws of Motion? What?! Wasn't this science muggly stuff and not a lot to do with space! He started scribbling confused notes down onto the paper, trying to keep up with what she was saying, using stars as bullet points so it looked a little more inviting when he had to read over his notes later on in his schooling life.
SPOILER!!: Terry's Notes
★Newton is a clever guy that came up with some laws about Rockets. They're called the Laws of Motion:
✪ Law One: The Law of Inertia:
“An object at rest tends to stay at rest and an object in motion tends to stay in motion.”
✪ Law Two: The Law of Proportionality:
“The acceleration of an object is directly proportional to the net force and inversely proportional to its mass.”
Confusing Equation: Force = (Mass) x (Acceleration)
✪ Law Three: The Law of Action-Reaction:
“For every action there is an equal and opposite reaction.”
★And that's why stuff flies around in space.
Who knows, maybe the notes might actually make sense to him once he had experienced a few more Astronomy lessons. He looked down at his notes and then up to the blackboard where more stuff had been written. Stuff which Terry didn't understand at all.
Everyone seemed to be talking amongst themselves and he simply didn't get what was going on. Something about water and a rocket and acceleration and thrust. The equal and opposite thingy sounded right. Everything had an opposite didn't it? Like push and pull. She was talking about how much water was going in and to him that sounded like it would change the weight and mass was kind of to do with weight. So the laws were starting to make sense to him but he had no idea how to apply it to the statements.
"Is thrust a force?" he asked innocently with his hand raised, staring down at his parchment and then up at the professor. "Because I think that the second statement and second law makes sense.. Sort of" he thought out loud. Yeah. "And acceleration is speed. Or the way something speeds up. Or something like that." Oh come on! He was good at CoMC and Herbology, not science spacey stuff. "The water effects the mass and you rearrange the equation thing and you end up with the force and the mass effecting the acceleration which is the speed and so the bigger the thrust, the faster the rocket will go." Did that even make sense? It didn't make sense in his own head so he was certain that the Professor would be confused by his answer. He would've stayed quiet but he wanted to give it a try, it didn't really matter if he was wrong.

Arabella-Marie cleared up her work station and then got her notes on Newton's laws out and then listened to what her fellow classmates were saying and was pretty sure that she didn't have a clue on what would apply to rockets and stuff so she just quietly listened to her fellow classmates
"Lovely work darlings, simply lovely," Professor Burbage praised as she walked around the room and looked at everyone's work. There were bottle rockets in house colors, ones that sparkled, ones that were hoping to help find a missing bat (poor dear), and then there was her junior studmuffin that had put her face on it. SIIIIIIIIIIIMPLY charming.
She looked at her watch and then at the progress of all her students and decided that it was about time to move things along.
Clapping her hands loudly to get everyone's attention, Marion made he way back to the front of the room holding her marigold colored bottle rocket under her arm. "DARLINGS! If you could please clean up your spaces now and set your rockets to the side for the time being, please. There is one more important matter we need to discuss before we move outside."
Suuuuuuuuuuurely they did not think that they were going to launch these inside, right? Silly little children. Ho ho ho ho!
"Now, if you could all please look at the board or refer to your notes on Newton's laws of motion," she said as she tapped her wand against the board.
"Without understanding these laws, mankind would have neeeeeeever been able to launch aaaaaaanything into space. Not satellites. Not monkies. Not humans. And ceeeeeertainly not rockets, which is why we are studying them. It is because of our understanding of these that all that was made possible and the field of astronomy was able to rise to new heights." She picked up her bottle rocket and held it up for the class to see. "Your rockets will be using water as its 'fuel' source. Meaning that water shall be the propellant that comes out of the nozzle here and shooooooots it up into the air when we pump air into it. In order to accomplish this, you will need to produce enough thrust. This muuuuuuuuust be greater than the weight of your rocket. For example, say this rocket here weighs 10 pounds," which it didn't, but that was not the point. "An upwards thrust of 10 pounds would keep your rocket stationary and at a constant level. 12 pounds of it wouldn't launch your rocket very high, but the trust would be greated than the weight of this rocket so it wooooooould move."
She paused for a moment tapped her bottle with her wand, filling it about 1/3 of the way with water. "Some of you may wonder why we cannot just use air to launch our rockets. The answer is rather simple darlings. Water is almost 800 times more dense than air. So, when your bottle rockets expel water, they will be expelling total mass and this increased mass results in increased rocket performance!" She paused for a moment so that students could write down any notes they wish. "Noooooow, some of you may be thinking, BUT PROFESSOR!? WHY DIDN'T YOU FILL YOUR ROCKET ALL THE WAY WITH WATER?! Tooooooo much water will cause your bottle rocket to be toooooo heavy and therefore hinder its flight. Too much of a good thing can be bad darlings."
But she was somewhat getting ahead of herself here. Oops. "Please keep all this in mind as you think over the following statements please, darlings." And she gave her wand a flick towards the board again.
She then turned to face the class, her smile as wiiiiiiiiiiiiide as can be. "Please select ONE of these statements and think about which of Newton's laws of motion best fits the statement. You may discuss among your classmates or siiiiiiiiiiiimply think on your own. You may share your thoughts whenever you are ready. We will just discuss this for a feeeeeeeeeew minutes and then head outside."
Alright. Off you go now all you future rocket scientists!
OOC: we will be moving on to the final part of the lesson approximately 24 hours from this post. Please pick just ONE of the statements above
Sarah put her rocket outside and wrote down more notes then she began to think about the teacher's question. Maybe it was law two as Law 2 says
Force = (Mass) x (Acceleration) which in his case would be Acceleration = Mass X force... The force would be the water pressure, the mass would be the rocket whcih will make the rocket go faster... wait that did not really work... or did it?

Blink, Blink. This was seeming less and less magical to her with every passing moment. Hannah cleaned up her area... not that there was a mess or anything. She placed her rocket neatly on the side of her desk. She really had to think about the question. It wasn't exactly hard, but it was boring to her, and a bit confusing all at the same time.
Hmmm... "Professor I think The Law of Proportionality goes best with the second statement because frankly the more fuel you use the faster it will go and the less fuel the slower it will go." This made sense right? "Kind of like if you throw a ball hard it was go futher, but if you just barely throw it, it obviously will not go as far." Hannah felt like she explained well enough that even the puffers would understand.

To say that he was quite eager to get his prototype flying would be an understatement, but he did try to keep calm and instead tried to channel that hyped up energy to clearing his workspace. With his bottle rocket set carefully aside he drew his notes parchment closer to him and listened as the Professor posed her question to the class.
Brows furrowed thoughtfully as his gaze scrolled from the Newtonian Laws to the two statements written below it. They're actually all related, and then there are a few variables missing such as the pull of gravity, but nevermind that for now-- Professor did asked to do the matchy thing with the statements below
"Professor, Newton's 3rd Law--For every action there is an equal and opposite reaction-- best fits the first statement--Rockets create thrust by expelling a propellant. The action of water jetting out of the bottle is the thrust that pushes it against the Earth's surface, and according to the 3rd Law, there is an equal force that pushes against the bottle, causing it to move the opposite direction of the thrust."

With the professor's interruption, Juliet placed her rocket on the side and cleaned her area. She didn't cut much so there's not much to clean really. After finishing cleaning and with her desk free from paper and whatnot, it was time to proceed with the lectures.
Juliet glanced at the board. She has no clue on what was written on the board. To Juliet, it didn't make sense. She can read it, yes but she couldn't simply explain what was written on it. Which is the hard part of this. Now she's just hoping that she's not going to let them explain one of them and ask them something weird like, what does this formula mean... something like that. Because Juliet has not much to say.
Then Professor Burbage just started to explain the stuff. Still, it somehow didn't made sense to her. She had that look on her face. She's just confused with it. She's confused of what she just said. Her eyes wanted to twitch which she controlled of not doing in front of the teacher. Muggles just had a lot of explanation to everything, it making everyone, technically probably just her, confused.
And then the question.... They had to discuss which one fit the statement. Juliet was afraid this would happen.... She could try though and hopeful she would make sense. Rockets create thrust by expelling a propellant (water in our case) The greater the thrust the faster your rocket will go she read what was on the board and then glanced over to the 3 laws.
"I think..." she started while poking her chin lightly with her finger. "the statement fits the 2nd law?" she wasn't sure even though. As to support this, all she can really do is try. "Because everything has to be proportional with one another. The weight and how well you built this rocket will be directly proportional to its acceleration." was it right, no?
What? This was Astronomy class right? Not some Physics class! She had heard such physics term in her summer vacations from her muggle friends, and had considered herself lucky to not to have to study it. but here she was!
Anyways, she was excited to launch a rocket, so she did realize that she would have to get her facts right if she wanted to do that. So she paid a bit more attention, and seriously thought about it.
She looked at both the statements. At first glance, it did look almost same, but then she thought about, and chose the first statement. Professor Burbage herself had said that rockets will be using water as its 'fuel' source. So she raised her hand up and answered, "Professor, you yourself said that rockets will be using water as its 'fuel' source. And when our bottle rockets will be expelling water to go up." Yeah, she had paid attention, see?
"So I think that the first statement agrees with Newton's Third Law of Motion. The action would the propellant coming out from down, which will have an equal and opposite reaction with the rocket moving up." So there, action down, reaction up, in simple terms.
"So the more fast the water ejected, the faster up the rocket will go.. I think.." She was correct, right? At least it felt so.

Bliss beamed at the Professor as she praised everyone. It made her feel specialllllll. She wondered to herself if the woman had noticed her, 'I love Astronomy' rocket, which she'd worked sooooo hard on. Clearly. The Second Year was enjoying the class so far and was happy with results of her ROCKET, she couldn't wait to test it out. But of course, first she'd have to do this little task. Didn't seem to hard to her.
Okay. The mini first bit of the task, was clear up. She did this without a fuss, moving the left over dental-floss and cardboard and putting on the desk where it was to start off with. At least, she thought that's where it should go. That's where everyone else was putting it. After she was finished with that, she moved her rocket to the far side of her desk, verrrrrrry carefully. She didn't wanna damage it. Nope.

“For every action there is an equal and opposite reaction.”
Bliss looked at her notes. The first law she had understood and changed it into a much simpler wording. But the other two, she couldn't think of any other way of putting them. The task was to discuss or think alone, about the statement of the board, which was: 'Rockets create thrust by expelling a propellant (water in our case). The greater the thrust the faster your rocket will go.' Bliss was already pretty sure which one it was and her hand shot up.
"Is it the second law?" Bliss asked the Professor sweetly.
Wait, she needed a reason to back it up. Force = (Mass) x (Acceleration). Urm, so.."The force is the thrust, right?" She asked, blinking and carried on thinking. "The mass is the, urm, water and rocket together?" Bliss said, slightly confused now. "The acceleration is...caused by the water pressure?" Bliss finished and blinked.
That sounded..right..wrong...something.

Nigel thought this Astronomy not rocket science. Why did they have to learn about some old guy's laws. Well It was not like he did not understand the laws. He was a Ravenclaw after all. This question was pretty easy.
"Professor The Third Law best fits the second statement. Because if you want the rocket to go farther. Then you would need greater thrust. The first reaction the thrust. would need the equal amount of speed to go faster."
Nigel was not sure if he said it right. But he could not say thing well. He knew right now. That he did not want to be a rocket scientist in the future.

Oh? They were to clean up now? But the young 'Claw was still at the restroom. Uh-oh. Beezus just decided that she arrange the materials the first year needed neatly on his desk, then she grabbed her own rocket bottle and returned to her own place. Maybe he'll come by in a bit.
One more important thing to discuss?
As instructed, she turned her attention back to the writings on the Board about the Laws of Motion.
Okay. Okay. Okay. The brunette just stayed nodding all the while Professor Burbage gave out explanations and examples after another. There were some she didn't understand, there were also a few she did get. Hmm. Relationship between water and the whole thrusting thing to launch their bottle rocket. That was understandable, and they were going to do the same, yes?
She was so ready to get started with the launching when the woman added more. HUH? The Ravenclaw eyed the statements on the board and started to think. They were to choose one and figure which of the laws relate with it? Frowning, her brain began to work like a machine. First, she chose a statement.
Rockets create thrust by expelling a propellant (water in our case)
She settled for the first choice. "Professor, I believe the first statement fits the second law of motion." Why did she think so? "Well, for one, the statement implies the water fuels the thrust created by the bottle. And if we relate it to the Law of Proportionality, the mass would be the water inside the bottle, and the thrust or the force exerted on the mass upon launch would point out how fast the acceleration would be." Was she making sense here?
Sigh. She wasn't really that good when it came to explaining things.

Ariana kept her thoughts to herself as she cleaned up her desk & still she kept her eyes open for the perp that disposed of there pop in her bag. well the more thrust power you have the higher & probably faster it would go.. right?!' she really had no idea. she wasn't a rocket scientist.. she was just Ariana and rankly she didn't care about a rocket

Awarlesta looked at her notes in deeeep thought. Well...it's either The Law of Inertia, or the Law of Proportionality. She thought harder, her forehead scrunching in concentration. No, wait. Force = (Mass) x (Acceleration). Yess. The mass times the speed is the force given! She shot her hand in the air with a pointed finger and exclaimed,"The Law of Proportionality!" in a voice almost equivalent to her exclaiming "Eureka!"

The entire time the professor was talking, Sierra just sat there, staring at her like she was speaking some foreign language. She technically was. Muggle-talk could sometimes be an entirely new language on its own. Then when you added science to that, the result was anything but understanding.
LE SIGH.
Sierra blinked again when they were asked to compare the bottle rocket to one of the laws of motion. Was this woman SERIOUS?! *bliiiiiiiiiiiiiiiiink*
Sierra just stared at the three laws. The first and third just didn't seem like it had anything to do with what she'd just made. That only left the second one, and...she only halfway understood it. "I think...it's the second one," she said, "...but only because I see the word acceleration." She had absolutely no idea what the rest of it meant, though. "...and because of what you said about our rocket needing a force to take off. I think number two describes that force."
