Toys - Forces Experiments

This week the children have been learning how to use these force meters available form any of the educational suppliers.

They designed an experiment to see the effect of friction. They pulled a laden box over different surfaces to see which needed the most force to keep it moving.

We also investigated the friction on slides by trying out different materials to make our slide.

Today we talked about air and water resistance.

Here L is running with a large piece of card to feel the effect of air resistance:

We made helicopters and dropped them down the stairs:

We weighed objects in air and water to see the effect of water pressure. We'll try some experiments in the pool next time we go.

We'll be working on parachutes next...
