6S have been learning about forces.
First some theory and a bit of History with Isaac Newton.
Then use the force meters to find out how much force it takes to..... open a door
choose the correct newtonmeter
How much force to move the bin
All busy. Then try the forces circus
Forces involved in floating
Or in draging a block along
Looking at surface tension
Tension in springs
And bending a stream of water with static electric forces.
