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’
