Junior Science Club

11 January 2018

In spring term, it's the turn of Y4 and Y5 to do Junior Science Club. We started with a short and fun experiment to make 'Cartesian divers'. You make a diver from a pen top, weighted so it is vertical, and floating at the top of a full bottle of water. There is an air bubble trapped inside the diver, so when you close the bottle and squeeze it, the pressure on the air bubble makes the diver sink, release the pressure and it comes back to the surface.
