As part of the natural sciences didactic unit, Machines and Inventions, grade 5 students have experimented building machines in order to demonstrate how using them affect the force used to lift up weight.
The simple machines used were the following: inclined plane, pulley, lever, wheel and axle.
Students also learnt that the unit to measure force is called: Newton (N).
In their experiments they used a spring scale to measure the force used.
