Heated Air



Heated Air
What  happens when air heats up? Think of an experiment and test it to see if the answer pops up. There are 4 paragraphs giving clues to answer this question , paragraph 1 will be about the supplies needed, 2 is explaining what to do when ready, 3 is a paragraph about observing and giving answers to any hypotheses brewing in the mind, 4 will reveal all the secrets, how it all happened and what caused it.
To carry on with the experiment, supplies will be needed:
1. tub full of hot water
2. a tub full of lukewarm or room temperature water
3. 2 fizzy bottles
4. 2 balloons.

Place the two tubs outside incase of any spillage. Wrap the mouth of balloon over the mouth of the fizzy bottle. Do this with the leftover balloon and bottle. Make sure the balloons are tight so no air escapes. The experiment can now start!

Immerse both bottles into separate crates. Something very noticeable will have popped up, the lukewarm water does nothing to affect the balloon. As for the other bottle that was forced into the hot water would have made the balloon blow up without using a pump or a human mouth. There is no trick, swap the bottles around to see if it does the same thing. The bottle that was once in the hot water is now in the lukewarm water. This made the balloon deflate. Same for the other bottle that was once deflated will now be slowly inflating.

By observing, there should be an idea of what happens when air heats up inside a bottle. If it still continues to circle the mind then try it once more. The balloon doesn’t seem to blow up as much as before. This is because the hot water would have by now cooled down. How does this affect it? The key is how hot the water needs to be.

When the bottle is immersed in the hot water it makes the balloon inflate by itself. The reason for that is the air inside the bottle is trapped when you put the bottle in hot water the particles expand which causes movement. The only place they can go when they are expanding is in the balloon because it is flexible material. That is why the balloon blows up. Why doesn’t the room temperature water make the balloon blow up? It is because the water isn’t hot enough so the balloon stays in a state of inertia. What happens when air heats up? The particles expand causing the balloon to blow up.




Above is my second copy. W did a second copy so we could play around with the writing and make it more interesting for the reader. Below is my first copy.

Success criteria:

Write an explanation that explains clearly to the reader

include title and intro that states your topic and maybe asks a question

include a summary statement that links with the intro

Write the body of the text in order using some of the key words - Suggest the sequence of the experiment  clearly - firstly, after that finally.

Include some topic-specific science vocab

Show how the process happens by using continuous present tense?  This will mean using lots of ‘is’ and ‘are’

Locky

When I walk in the lounge and all the lights are out I suddenly see two shiny black dots move around the room.They’re moving everywhere almost unable to be catched. I realised that I have seen these before. It's Lockys beady eyes. He rubs his head against my leg as a sign of he wants the light on. I flick the switch and turn around to see Locky rolling around on the floor. His black and white curls seem like he has been coughed on by the fire and ashes have gone everywhere. His wagging tail shows me that he is happy to see me and wants a pat. I look at his long curls that droop to the floor and wonder if it’s time to get a haircut. I only came out to get a drink of water so I turn off the light and everything becomes complete darkness once again. I see the beady eyes following me back to the bedroom. He quickly and quietly sneaks past me and claims half the bed all to himself.

Throughout the night I can feel his ears twitching. He tries to wipe his drool on my arm but seems to get the blankets instead. The only thing that gets me was the rebound of his scaley tongue trying to climb back into his mouth.
I rose out of the bed the next morning and stretch my arms out as far as they go. Locky is already up, probably in the kitchen waiting for someone to stack his bowl full of dog biscuits. I walk towards the door, suddenly he pounces out from under the bed. His back is arched and and his paws are flat on the ground. It seems like he is trying to tease me into playing with him. I grab his chewed up tennis ball and throw it out the back door. He picks up his body and scrambles to get outside. Within a second he his crouching by my feet again. I decide to pat him instead, his curls have a chalk feeling to them but thats just the weekly knots. He jumps up with his paws pressed against my legs. They feel as soft as a feather pillow. He rolls over and you can the bald patch around his stomach. His belly started jumping up and down like a vibrating toothbrush.

He gets very impatient and starts barking like a huge threatening guard dog. He is no where near the size of a guard dog though. He turns to the side and pulls his body up off the ground. The whimpering starts. It carries on for as long as you can tolerate it. The untuned horn noise seems to get louder and louder. Angrily, I turn around and pet him. He start to breath heavily as a sign of him getting his way.

Gravity VS. My Force


Tuesday 15th our class decided to step up to gravity and see who could keep their arms up for the longest. It didn't take long, half the class had given up within 3 minutes. As for Thea, Phoenix and I we were on fire. Literally we had been holding up our arms for so long that it started to burn. To stay in the competition we had to keep our arms up above our shoulder length, they warn’t allowed to bend and finally our fingers had to be straight. Time went by and the pain seemed to spread. We started 11:50 and us 3 finished as a draw at 12:40. It was such a relief to finally put my arms down. The pain lasted throughout the day but it was all worth it. I think this was a great way to show how powerful gravity is and how no one is able to defeat it. At first I thought it was a fun activity then it turned into an extremely hard competition. In the photo below I am trying to do my work as well as keeping in the competition.

Flexability

Monday The 14 our class tested ourselves and how flexible we are. To test how flexible we are, we created our own equipment that included a plastic box and a piece of wood, longer than 60 centimes. You place the piece of wood on top and draw the measurements. 30 centimeters on the negative side and 30 centimeters on the positive side. For our first try I got 11 centimeters on the positive side of the ruler. I tested my flexible skills with Poppy, Thea, Daniel and Charlotte. The highest mark was Thea's, she got 18 centimeters positive on Monday. On Friday we will be trying this to see if we improve our flexibility skills. Every day in between we did hamstring and lower back stretches to try and get a better mark. I have improved by 1.5 centimeters. Others improved by 5 centimeters or more! Only a few decreased.

Monday
11cm
Friday
12.5cm
