The pupils realised that you can make a really stable toy by making sure that the centre of mass is below the point (the pivot). Robbie showed that maybe tightrope walking is not as hard as it looks – just get a long bendy pole!
The pupils all managed to do the fork balancing trick! It looks impossible, but because the centre of mass of the two forks is somewhere between the two handles, it is possible to balance them using a cocktail stick and a glass (or measuring cylinder!)
The pupils have been stretching springs and plotting some fabulous scatter graphs.
Here is our final result graph:

The pupils have been showing off their chemical skills by making some different crystals:
