Action and reaction.

Last week our school science electives put our science hats on and learnt about action and reaction,we learnt that in every action there is an equal reaction. We used a balloon, string, tape and a paper straw to demonstrate this law of physics.

We cut the paper straw into small pieces and used one to slide on the string.Then we blew up the balloon and taped it onto the paper straw. We had our teammate Eria holding one end while Ruby was holding the ballonI was on the other side of the string holding it. Ruby let go of the balloon and it shot off to me and stopped.

When we release the balloon, the pressurized air in the balloon pushes against the air around the balloon sending it in the opposite direction down the string.

I found it easy to assemble the task because it is very simple and the names of the tools aren't too long for me.

I found it hard to understand the physics at first because there was a lot behind it but now it's a little bit easier.

Next time I will try different approaches like changing the tool brands or use more or less.
