Year 5 used K'Nex to investigate with levers, pulley and gears as part of our topic on forces.
In this Science lesson, we had to see how easy it was to pick up a cube of jelly using two pencils. It was quite easy! Then we added cooking oil to the jelly and we had to see how easy it was then! The children found this quite a challenge as the cooking oil reduces the amount of friction between the jelly and the pencils. We had lots of fun trying to pick up the jelly!
