Investigating Pneumatics

This morning we built on our prior learning about the inventor John Boyd Dunlop. We knew what pheumatics meant but wanted to find out more about how it worked. We set up three experiments using ballons and syringes to explore how an object could be filled with air, rotate and have force applied to it. 

Here is a write up, completed by some year twos:


We needed:

5 balloons

1 book


First, we needed to blow up the balloons. Each balloon needs to be blown up to a different size.

Next we put a book on top, pushing down but making sure the balloon didn’t pop. We put quite a lot of pressure on it to make sure it could be moved left, right, forwards and backwards. The book was acting as us sat on a bike.


We found out that the pink balloon was better as it was about ¼ allowing us to apply pressure whilst holding enough air to make the book move around with bursting the balloon. The deflatted and the biggest balloon were useless because they were sliding or sticking to the surface. If we were on a bike we would have fallen off!


Our Science Morning with Mr G!

Still image for this video
Mr G came in for the morning. What an amazing experience! The children loved all the experiments and practical exploration of the magnetic field, camouflaged animals, sound waves and much more. Here is a video of our big finale! The children have not stop talking about the big bang and have been using sceintific vocabularly to explain and describe all of the activities that they completed. Well done Class Two!
