Using Lego to Teach - Basic Levers

The basic Lego lever. A few brick and a pivot is all that is required. The pivot needs to allow the bar to more freely.
A homemade lego weight using a lego rock filled with 1p's. This gives enough weight (load) to be noticed using a finger as the effort.

 A first class lever. Press on the yellow flat brick.

A second class lever such as a wheel barrow. It is necessary to lift under the flat yellow plate.

A third class lever such a fishing rod or tweezers for a pair of third class levers. It is again necessary to lift under the yellow plate.
