Fulcrums, levers and pulleys

Today we joined up with some 2F students and learnt about how people lift heavy things using simple machines. Levers make moving things easier. A seesaw is an example of a level and it has a fulcrum to help balance it.

We made a lever using a pencil, a ruler, sticky tape and playdough.

First we put the fulcrum in the middle and needed to use the same amount of playdough.

Next we changed the fulcrum to make the lever uneven and used different amounts of playdough. It was fun!
