We’ve been investigating forces and air pressure.

We made card helicopters to investigate air pressure and its role in keeping a helicopter in the air!

We made one large and one smaller helicopter and then we anchored and weighted them with a paper clip.

We discussed which helicopter would reach the ground first, and therefore which would stay in the air for longer- which would be a better vehicle for us!

Testing!

The test had to be fair- no throwing the helicopters and the release had to be from the same height!

We tested in our GP space; lots of room for testing there!

We used more weights too.

What fun in school children have now!
