Despite today's lesson being held in the early afternoon, an unusual chill had taken over the Astronomy classroom. The professor had a few Heating Charms in place, but they did not seem to be making too much of a difference. The desks are arranged in their usual semi circle and as you approach your seat you notice that there is something strategically placed right in the middle of the desk.
Professor Flamsteed is standing at the front of the classroom leaning against his desk with his backside with his attention on the long red balloon in his hands. Twisting and untwisting it, he tried to remember the correct steps to making the balloon creation...but only succeeded in making that horribly squeaking noise cause by balloon rubber rubbing against itself. SQUEAKY REEEEEEEEK SQUEAKY SQUEAKY REEEEEEEEEEEEEEEEK.
Did you remember to use the lint roller on the small table outside of the classroom? It was there next to the sign that reads, "Not to be used as a brush for your hair."
So come on in and have a seat. Class will begin shortly.

▸ Class dismissed!
Angel stopped bumping into things and then she smiled as she raised her hand. "Professor, the Charles law is an experimental gas law which tells you how gas tend to expand when heated." Angel thought about something before continuing. "So I take it Professor that Charles has created this law and no one knows if it works so they are saying it's an experimental law."
Her father loved this things..and had tried to explain to her..
Lucy said..The Boyler's law says that at constant temperature the condition of a perfect gas is inversely proportional to its volume..
My father loved to diving with me and had told me this law..

Oh, so she hadn't had the right answer? BOO. But at least she had the right answer to a different question! That meant she didn't have to try hard when that question was asked. She could just shout out the answer she'd already given. WIN!
Now the professor was asking about some Astronomy laws, which just confused Sophie, because there were TWO. Which one did she shout out her already-said answer to? She thought it was going to be easier than THAT. Come, Flamsteed!
"BOYLE'S LAW!" she yelled out. "IS THAT WHAT I WAS TALKING ABOUT WITH THE BALOON? WHEN IT GOES KABOOM?! WHEN THE PRESSURE GOES UP, THE VOLUME GOES DOWN!"
...and that had been the reason why her balloon poodle died on the classroom floor. Sad.
Nigel stopped a while ago bumping into people or not. He did not care enough to remember even a few seconds ago of work. He just walked around the circle. Glaring at people to make sure they would not bump him. It seemed to be working marvelously.
Getting Sidetracked as Nigel usually does. Flamsteed must have some lungs on him to shout, talk, and run around a room and not get tired until some Gryffindor runs into him. Which was a genius way of being a air molecule by the way.
So Nigel has to explain either Boyle's Law or Charles' Law.
Hmm...how about option C. None of the Above and just hmm the ABC 123 song. sounded good to Nigel. Since an example of Mariotte's law is basically just the death of deep sea creatures due to change in pressure. Or simply the popping of a balloon.
Simple Enough

Er. Dima didn't know all that much about either law, and some other students were staying quiet too. Obviously, it was alright for him NOT to contribute, but he liked participating. He was sure Professor Top Hat wouldn't mind a COUPLE of wrong answers, right? Especially from a first year. He was doing his his best, mind you.
"Um... I know Charles' Law is that law made by that.... Charles dude. It's about... temperature and volume and stuff." Like the professor had said. "They have that.... you know... relationship where... uh.... one goes up and the other goes down and.... and you got what I'm talking about, right?" Right? No need to explain!
Nodding vigorously, he piped down. Nailed it.

The classroom was really heating up with all this jogging. She could almost feel it radiating off everyone she jogged by and the people who jogged by her. Smart thinking Professor and the warmth was appreciated--the jogging was too. Being trapped in a castle brought on some desperate need for ANYTHING that could induce moving and no going up and down the stairs to classes didn't count.
Kevin losing points hardly registered to her. Kid was a lost cause and just like Bart he was not her problem. None of them were. It wasn't like she was a Prefect or anything. She didn't have a say in any of it and just kept jogging.
In her opinion, both laws were covered by the other joggers and Lex was too busy in a happy warm place in the back of her mind. Good thing she'd had those chocolate frogs before class. Perfect way to burn the sugar away and it made keeping up super easy.
Almost made her miss Alice driving them at 5 am for practices....almost.
So yeah, don't mind us while we silently jog over here.

"PRECISELY!" he applauded. Literally. His arms were above his head clapping as he jogged backwards. "As Miss Somerlad put so concisely, air pressure and temperature are proportional to each other. When one increases, the other increases. When one decreases, so does the other." Fascinating, wasn't it? He certainly found it to be, so hopefully he wasn't alone in all this.
"If any of you have ever listened to the muggle weather forecast, you heard them throwing out the terms high pressure system and low pressure system," he continued as he continued to jog backwards. "A low pressure system occurs when air moves away from an area faster than air enters it. When air spreads out, this spreading is called divergence, at high altitudes, air from below flows upward to fill the space, making a low pressure system," he explained complete with dramatic arm movements. "Air piles up, this is called convergence, on the surface and has anti-clockwise rotation here in the Northern Hemisphere."
They really just needed a very very basic understanding of this, so no need to panic over the details.
"A high pressure systems form a bit differently. Instead of air speeding up, it slows its forward motion down," he said as he quite suddenly slowed his own movement to illustrate. "Convergence occurs high in the sky and once the air has piled up it begins to si -----"
OOOOOOOOF!
Mr. Hirase's movements were not only unexpected, but also incredibly ill-timed as he was in the middle of his explanation. Wind knocked out of him, but not physically knocked over because the man had more balance than that. He leaned one hand against the wall and panted to catch his breath before continuing.
"....sinks. When this air reaches the Earth’s surface, divergence occurs with clockwise surface rotation," he said, completing his initial thought in a significantly high pitched voice than before and the occasional wheezing.
He then looked at the Gryffindor and sighed. "5 points from Gryffindor. And I expect a two inch essay delivered to my office by the end of the week on the word 'gently'." He was serious too, about that essay.
Would have been 10, but he gave the boy 5 back for the out of the box way of demonstrating the increase in pressure. Heating up. Speeding up. Crashing into more things. Doing exactly what he had asked in thinking like a molecule.
Finally catching his breath, and rubbing his side a bit - Merlin that was gonna leave a bruise - he did a few sprightly high knees to get his blood pumping again before he resumed his jog. "Everyone keep moving, we're almost there." Probably. He had actually forgotten to attach his step counter to his sundial watch after lunch to be sure. Oops.
"I would like to back up to something Miss Newell brought up. Miss Newell mentioned volume, which is another one of our ingredients for the weather. To understand how volume is related to air pressure and temperature, we need to understand two laws. Charles's Law explains the relationship between temperature and volume while Boyle's Law explains the relationship between pressure and volume. Please pick one to shout an explanation to."
Ready? GO!
"OH! You can stop bumping into each other now." He was positive that the point had been made.
She had heard about high and low pressure systems. Penelope listened to the professor's explanation, trying to remember everything so she could take notes on it later. Not bumping into any more people, she continued to jog around the room.
Was that a thumbs up from Flamsteed? The shouting must have worked, so she shouted her next answer for the new question. "According to Charles's law, the volume of a gas, at a fixed pressure, is proportional to the temperature. When one increases, the other increases. When one decreases, the other decreases."
Alright so they needed to talk about Boyle's Law and Charles Law? Hmm weird name for the first guy that is for sure. He didn't even know these laws to be honest. But he did agree with Sophie's answer. He just kept running slowly. He didn't need to repeat any answers that were already said. Plus it did make sense with the balloon popping! He grinned and he was surprised he wasn't out of breath yet. Maybe he was just used to running a lot. Yeah that could be it.

Arista blinked she heard of that Boyle one from her muggle side of the family. When they got all nerdy... She held in her laughs and cast a smile towards Professor Flamsteed as she raised her hand. "Boyles Law states as pressure goes up, volume gets smaller, and temperature and quantity are constant. " Kind of simple terms but it was the easier way that she remembered it. Science wasn't really her forte but astronomy was starting to since she was reading that book she got from the Professor.

No more bumping, thank Merlin! If someone else was to as much as touch her arms Beverly was going to judo flip them. She would. Tossing her hair that had fallen forward behind her shoulder, she strained her ear to hear what Airey was saying next.
It was a good thing she did her reading, huh. Something about this prickled in her mind, so she raised her hand. "Charles's Law!" Did she have to yell? It was ridiculous. Sorry, Airey, it was. "When temperature increases molecules move around faster, creating more force and resulting in the increase of volume!" Yeah? Did she remember that correctly? "Also! There's an expression or formula-" whatever "- to follow?!" RIGHT?

.....who is Charles and Boyle anyway?
Ethan kept jogging, until he heard Simon offer his answer. Well, obviously most of his classmates were saying the same thing over and over again, and thought it pointless to repeat it. Besides, he's just going to pretend that he knows who those dudes are, so he just kept on nodding and busied himself to keep warm. He did however, jogged backwards to where his best bud was...and...was Simon taking notes? While jogging?
Elementary, but impressive.
Anyway, hiya there Watson! Ethan hoped Simon won't be too stingy with his notes later. Right. Jogging some more...

Rubbing his side every now and again - yep, definitely going to have a bruise there - the astronomer's forward movement slowed just a bit to compensate. Checking his sundial watch briefly, he estimated just how long they had been jogging around the room and calculated that after this series of questions and answer that it would be about time for one final question before moving on to the activity.
Whether or not the activity would actually work, well, that was all up in the air. Literally.
SPOILER!!: the quiet joggers :3

Gryffindor was in a pretty good spot as of right now. Hopefully Kevin wouldn't cost anymore points this lesson. Hmph. Kev, why WHY!?
Anyways, as for the question, Zander had no clue. He was much more comfortable watching others answer. It was what he did best.

What made him flinch when it came to points was when he had earned them from Bentley once while cleaning up the boys dormitory with Zander. THAT had been weird.
He pushed himself away from the wall and whispered a "worth it" loud enough for only the Professor to hear as he walked passed him. But then he had to say the word essay and Kevin snapped his head towards the man and looked disgusted. "whatever" he pretended he didn't minded it.
On to the question. Which was something he had no idea over. Actually, he didn't even know the Laws or whatever they were. He just wanted to bump against people. Booo! So not knowing what to say, Kevin remained silent for now and folded his arms over each other and glared at the Professor for making him write an stupid essay.

Soph rolled her eyes at the whole fiasco, unamused by the Gryffindor being himself, and she felt sorry for the professor, but she was glad he was okay. And even more pleased by the kid's punishment. Hehehehe.
She was still jogging away, and even though the topic was currently sort of interesting, Sophie didn't have any input to Flamsteed's next search for answers - she was content to entertaining herself with the occasional exaggerated jogging motion and making wiggly eyebrows at Tobes and spying on the people she didn't like who were currently present. There were only three of them there today, so that made it easy to keep tabs on all of them. Heh.

Through the chorus of answers, the astronomer did notice those that chose to remain silent and focus on their jogging...or attentive listening. "Don't stop now! We are nearly there!" he called out as he picked up his own pace just a little bit more
PHEEEEEEEEEEEEEEEEW...he was starting to get a little winded here. Not to mention he could use a change of scenery. Felt like a bloody goldfish swimming around in a bowl passing by its plastic castle over and over again...even if the running joke was that they had terrible short term memories. He wouldn't know. Fish were not his thing.

GOOD.
And thank you for only GENTLY bumping into him, the people who had. He appreciated that. Really. No bruises for him. Though, thank MERLIN that they could stop bumping into people now. It was starting to get a little tiring, especially when mixed in with the jogging. Besides, some people liked to get a little touchy feely and that was NOT something he wanted, thank you very much.
Hearing an explanation, the Grayson turned his attention back to Flamsteed. Oh look! Cassia's name had been mentioned, as had Soph's. He felt a surge of pride course through him, one that he was sure had a lot to do with house pride. Uh huh. He would have even shot them a proud smile but, seeing as he didn't know where they were, the smile had to be left for later.
As for the question, Grayson decided to opt for Charles's law. Why? Even he didn't know. Maybe it was because, after a couple of seconds of thinking, it wasn't as hard to find a connection between volume and temperature as it was to find a connection between volume and pressure. So, yeah, shouting. "ACCORDING TO CHARLES'S LAW, WHEN THE TEMPERATURE GOES UP, THE VOLUME GOES UP TOO!"
Smart, he was.

Right. So the suited man was speaking again. Adi stopped with the jogging and bumping to think. "Charles's Law says that if temperature were to go up so would the volume,'' the Hufflepuff finally shouted.

"Charles Law states that the temperature of the air directly affects the volume, so when it gets hotter, the volume gets larger!" he answered. Everyone else was shouting and it was contagious so...he was shouting too. Oops.

She could endure loudness, of course. No big deal.
Stopping from all the... walking, she simply spoke... a bit on the loud side, but without SHOUTING LIKE THE OTHERS, the law of volumes,"Charles's law...," she started, "...in which the volume expands as the temperature gets higher." Definitely, that was easy to understand. Same as pressure.
And Boyle's law was the opposite.
All was well. Except the overall volume of her classmates.

Awww, they had to stop bumping now. What a shame. But Professor Flamsteed was explaining more things to them, so it was probably for the best that she wash't distracted by crashing in to people. This kind of made sense to her. Air pressure was tied to temperature; even if she forgot some of the details that much would be easy to remember.
Boyle's Law or Charles's Law? What did she know about either one?
Biting her lip, Lux tried to remember. This exercise had to be good for her brain, so surely would come to her. She had looked at the textbook before term started, but that was a while ago by now. Focusing really hard, after a moment something came to her. "CHARLE'S LAW STATES THAT AS THE TEMPERATURE INCREASES, THE VOLUME ALSO INCREASES." Hopefully she wasn't being too loud, but she wanted to make sure that the Professor could hear her.

Shaking his head towards Mr. Toussaint as he ran backwards, he gave the chorus of replies two very enthusiastic thumbs up before going into futher explanation regarding this particular concept. "Correctomundo!" he cheered. You know what was sad? All this running around meant he couldn't leap on to desks, and that was a real pity. "Charles' Law was discovered by Jacques Charles, as French natural philosopher Joseph Louis Gay-Lussac refined the law much later. Jacques Charles discovered that the volume of a gas at constant pressure changes with temperature. So, as many of you said, when temperature increases, so does the volume. When temperature decreases, so too does the volume. "

Jasmine listened to the Professor's next question and noticed that they were becoming harder each time. At first her mind was totally blank. She knew that she had read about Boyle's Law before, but really had to rack her brain to remember the information. When the light bulb finally went on, Jasmine shouted out her answer. "Boyle's Law says that when the temperature is constant, the pressure and volume have an opposite relationship." At least she thought that was what she remembered. The memory was a bit fuzzy and the complete explanation was complicated.

Those names sounded very familiar. He remembered his older brother had been trying to explain their properties to him a while ago. Pulling out a mini notebook from his trousers' right pocket, he jotted down some notes about the two laws.
With the two laws in mind, he focused on Boyle's law. When the temperature of an ideal gas is fixed, pressure and volume were inversely proportional.
Simon shouted more excitedly this time as he tried to match his mate's, Grayson's volume. "According to Boyle's Law, pressure and volume are inversely proportional when temperature is fixed. So basically if volume increases, then pressure must decrease. The reverse is true. If volume decreases, pressure increases."
He was pretty sure that was it.
SPOILER!!: mini notebook
Charles's Law explains the relationship between temperature and volume while Boyle's Law explains the relationship between pressure and volume.

They could stop bumping now.. What about jogging? The Hufflepuff groaned and speeded up slightly. Charles's law and Boyle's law? She remembered reading about one of those laws before, but forgot which it was. Worth shouting out anyway.
"I think it is Boyle's law, which states that the pressure of a gas decreases as the volume of a gas increases." Leah said out loud. Still.. Jogging.. And panting.

Now the professor was asking about some Astronomy laws, which just confused Sophie, because there were TWO. Which one did she shout out her already-said answer to? She thought it was going to be easier than THAT. Come, Flamsteed!
"BOYLE'S LAW!" she yelled out. "IS THAT WHAT I WAS TALKING ABOUT WITH THE BALOON? WHEN IT GOES KABOOM?! WHEN THE PRESSURE GOES UP, THE VOLUME GOES DOWN!"
...and that had been the reason why her balloon poodle died on the classroom floor. Sad.
The astronomer managed few humble leaps with this chorus of responses. Lots and lots of stellar stuff here kids! Maybe he should make everyone run around the classroom every lesson. Really get the heart pounding, blood pumping, and brains churning.
"Excellent! Eeeeeeeexcellent!" he grinned. "Boyle's law is named after Robert Boyle who confirmed through scientific experimentation the research of Richard Towneley and Henry Power. This law states that, with a fixed amount of gas, when the pressure is increased, the volume is decreased. When the pressure is decreased, the volume is increased. Think of pressure and volume being two kids on a teeter-totter. When one goes up the other goes down."
Actually...that sounded sort of fun right now, didn't it? Should look into asking Kirby about getting a set of giant ones for the grounds next term. Assuming the man came back. His bees dying off like that because of the cold had really taken their toll on the bloke.
He glanced around until his eyes returned to Miss Newell, because her response had caught his ear. "Boyle's Law, as Miss Newell alluded to, is easily explained by using a balloon as a reference." Which would probably be a good time to head back to their desks now so they could play around with the balloon themselves...but they still had more running to do. "Which also relates to something Mr. Atreyumentioned earlier - density. The air pressure inside of an inflated balloon is stronger than the atmospheric pressure outside the balloon. The density inside the balloon is also greater than the density outside. Thanks to Boyle's Law, we know if you squeeze a balloon to halve its volume you end up increasing the pressure on the balloon and pressure is directly proportional to density. That means, if the pressure in the balloon increases, so does the density, and if the pressure goes down then the density decreases. Because of that, when you squeeze the balloon and halve its volume you increase the density of the balloon. The increase in pressure that occurs when you halve the volume of the balloon is why balloons pop when you squeeze them."
And that was why a balloon pooped. Which was also related to the weather in a sense, but he was now sufficiently sidetracked thinking about balloons.
Okay...last bit of long explanations coming up. He promises.
"Now, I know this has been a LOT to take in, but I am sure you are able to see all sorts of relationships among these atmospheric variables, or as I have been calling them...our ingredients for the weather." Slight wheezing was happening now because he was out of breath. Aaaaaaaalmost there. "Atmospheric scientists express these relationships in two ways," he continued as he waved his wand in the air to use Flagrate and write two equations in fiery lettering.
Equation of State/Ideal Gas Law
Pressure = Temperature x Density x Constant
Pressure x Volume = Temperature x Constant
"Have no fear, I will not be asking you to do any long calculations today, so this is simply for your reference. Likewise, understanding all weather conditions and why things occur will take far more time than we unfortunately have." Because he hadn't even touched on several other aspects of things, but putting too many ingredients into the pie was cause for disaster. So just the basics today. "The above equations help meteorologists figure out whether air will be stable air or unstanble air among many other things to help predict the weather."
"Alright...I want everyone to STOP!" he said, panting and leaning forward a bit to rest his hands on his knees to catch his breath. PHEW! Feel that heart pumping. "We have been jogging around for quite some time now and are perhaps only a third or fourth of the way to reaching our goal of approximately 10 kilometers." Yep, you all were meant to run a marathon today! Just kidding. "While you all stretch and cool down a bit, can anyone tell me why 10 kilometers is significant?"
OOC: thank you all so much for your patience and my sincerest apologies for keeping you all waiting far longer than I anticipated <3 This lesson will continue sometime after I have had sleep (it is now 12:05 am in my timezone, so you are looking at at LEAST 14 hours from the time of this post. We will be moving on to an activity next

Sophie could hear something about an equation, but that went over her head. So she just kept on moving--that is, until she heard the word STOP. She stopped in place and turned to face the professor. They were only a third or fourth of the way to their goal? What goal, and why was it taking so long to get there? Now the professor was talking about ten kilometers and why it was so significant.
Could Sophie tell him why? Uhh, no.
Then it occurred to her. What in Astronomy took a really, really long time? A lot of things did, but they were traveling, which meant the answer might have something to do with--"Is it a light year?" she asked, raising her hand. "Or, does it take a whole bunch of those kilometers to equal light year?"
Abbi stood a bit to grasp some air. She would of answered those other questions, she really would but that running had been more than enough and anyways people were answering before her. What was so bad about just listening anyways? She would still be absorbing right?
HEH. Anyways this new questions, well she totally knew the answer and maybe it was just about time she answered something. "Well Professor, 10 km is important because that's where clouds usually begin to form at their dew point, no?" Was she right then??

He wasn't going to PRETEND like he understood anything Professor Top hat was saying because, really, Dima had no clue. Could he hear himself talking? Did he know what he was saying? Why could he not see that it was total gibberish? Something something something popping balloons.
That was literally all he got from that.
But he DID know something about the next question. Maybe.

"A TRILLION of those are!" Yeah! He knew! Him! Dima Toussaint! Him! HIM.
Did he get a sticker?
If not, he'd just get Kyroh to give him one later.

Finallllly they were stopping. This was good. Mitchell looked at the formulas for a second. They weren't seriously going to do math while jogging, right?
... and they weren't going to be doing a 10k. Right? That was a marathon! And apparently also something significant to weather...?
Weird.

Stop. STOP.
Thank Merlin, the jogging is over.
Ethan's got no idea about the relevance of the 10 kilometer thing. Was he supposed to know? Was it elementary stuff? Well, never mind that, because he's got a question of his own. HOW can one Airey Flamsteed jog around the classroom AND give out information such as formulas and stuff at the same time?
Merlin, he needs to take down notes pronto. Or maybe not? Maybe Simon's got that skill too? Taking down notes while jogging, and not poking his eye in the process? Yeah...skillful Watson. Ethan's impressed. Well, back to the question though. 10 kilometers? "Is it part of an equation?" No need to confirm if he got this right, because he was too tired to even stand up. The boy unceremoniously flopped on the floor and streeeetched his tired legs.
They're supposed to do warm ups first, 'fessor Flame-o. Not the other way around. Mhm.

This running was starting to tire Lux out, so she was rather happy when they got to take a break. Not only were her legs and lungs starting to feel it, but so was her brain. There was a lot of information coming at her, and it had been a while since she had read up on this stuff in the textbook.
Trying to catch her breath, Lux wasn't sure how to answer the next question. What she really wanted to know was if he actually expected them to run 10 kilometers, because if so she didn't think she would make it.

Jasmine kept jogging and wondered just how far the Professor would have them run. She wasn't bothered by it yet because she liked to run and running made her numb.....numb was good. Trying to focus on the information being presented, however, was a challenge. Jasmine was not upset when the Professor finally told the class to stop running.
Then there was a question. What was significant about 10 kilometers? That's how far away Jasmine's mind was from Astronomy right then? Really, she had no idea what the significance of 10 kilometers was and she couldn't seem to come up with a plausible answer. Sooooo until she thought of one, Jasmine would stand quietly, stretch and try to be invisible.

Nigel was already stopped and could not stop running when he already was not. Just the thing you ponder while watching people run. And there he goes again. Does he ever stop for drink of water or even a break. Not that Nigel has seen. Even after getting run over. Flameo was superman or something. Maybe he was making us do this in preperation for an iron man or 10km Run. That must be it. Preparing a class for your own personal agenda did sound pretty awesome.
"Because you are practicing for a 10 kilometer run."
Though he did like Dima's answer.

OH, GEEZ. Declan ran a hand across his forehead. The professor nearly gave him a heart attack there. The sight of the equation almost sent him jogging out of the classroom. Math is not something he's fond of. Horrible thing, math is.
Oh, thank Merlin they could stop jogging. Not that he really was, but still that's his exercise for the week. 10 kilometers...10 kilometers?!! Nope. Doesn't ring a bell.
Yeah I broke that mirror, so what? ll NOT backward ll Official Gryfferin ll Lemon's favourite
Oh, they were stopping now? But...but they were just starting to warm up. Lex felt like she was burning some real sugar just now, did you know that Professor? Being winded didn't matter. Lex never thought she'd missed a feeling more than this one. Being tired and getting extra air into your lungs if you want to breath. No quidditch was bad enough but then you add not going outside and you might as well had made her old again.
Lex leaned against a section of the wall trying to catch her breath. You think she'd be trying to internalize all that was said but no, she was effectively clearing her mind and taking deep breaths.
Could they do this again? Almost hitting 10 km sounded impressive and like it was actually worth something in this castle. If only they'd done this distance in laps around the Quidditch Pitch. She would have loved Airey forever--not that she didn't already but you got the idea.
Like most of the class as it would seem, the Gryffindor was lost on this 10 km thing and it's significance but that might have been because of all the deep breathing and just winding down from the job she was doing.

Thank MERLIN that they could stop jogging now. Really.
Grayson did stop jogging almost as soon as the man said so and stood there, taking deep breaths and clutching onto his sides. It wasn't that he was unfit -- he was VERY fit, thank you -- but being inside meant that he hardly got the chance to do any exercise, let alone jog. Not that he was complaining. Nope. He was HAPPY that he now had an excuse to not do any exercise.
Besides, running up and down the stairs for classes was enough exercise, thank you.
And that explanation with the balloon? Lol. LOOOOOOOOOL. He understood very little of it. It wasn't that Grayson wasn't trying to understand, he was! But somewhere along the long explanation, the boy's mind became more and more confused and he wouldn't have been surprised if it had given up trying to understand it all. What he had gathered was: air pressure inside an inflated balloon is greater than the atmospheric pressure, density goes up, Boyle's Law (??), balloon squeezing, halving the volume meant increasing the pressure (????????), blah blah proportional, blah blah something more about pressure and density (what), blah blah blah lots of words and then............
................ balloon went pop.
And then there were equations. Brilliant. Of course there'd be freaking equations.
Thank MERLIN that they didn't have to use the calculations today. He was going to hold up his candle of hope that he didn't need to make those calculations ever. Never ever. And as for the question, he was going to go back to the previous answer he thought of: atmosphere. This lesson seemed to be all about that, or that's what he liked to think.
So, up went his hand in the air. "Does it have something to do with the atmosphere again? Or the stratosphere?" What was the difference?

They could FINALY stop jogging. YES. It was right on time. Phew. Simon felt if he had been jogging any longer his legs would have crumbled and he'd have his face hit the floor. Eh. That was probably a bit too extreme a thought; however, the boy definitely felt that way. His muscles were starting to cramp up so he started stretching out his legs. Ahhh... Much better.
Simon stopped jogging and took several moments to catch his breath. As Airey spoke, he continued writing down notes in his handy dandy notebook.
SPOILER!!: more notes!
Equation of State/Ideal Gas Law
Pressure = Temperature x Density x Constant
Pressure x Volume = Temperature x Constant
Ah question time.
Simon blinked, utterly baffled by Airey's question about the signifigance of 10 kilometres. Wait. What? Uhh... Did it have something to do with the atmosphere? "Does the 10 kilometres have something to do where weather takes place? Somewhere up in the atmosphere? The Trophos-something-sphere?" he guessed. Yeah that was totally it. The Trophos-something-something- sphere.

So Mo was feeling a little dense. He'd read up on the chapters about... those two laws, but he hadn't been nearly as fast with an answer as the younger students. The running felt good, though, and maybe he was just enjoying some physical activity and had been completely distracted. Maybe. Or maybe he was so deep in the NEWT dregs that he could barely function in normal classwork.
He wanted to participate, though, so when the professor had them stop running and threw another question their way, Mo was in full show-off mode. "The first 10 km, on average, of the atmosphere is known as the troposphere, Professor. That's where weather generally occurs, because that's where most of the mass and water vapor resides." Or... was that right? Where was his book?
