A 3.1 What Does Have an Arm in Common with Pliers?
Marco Spurk
- The students learn what levers are and how they are used in the everyday life.
- They get to know the function of their own arm and learn where the muscle insertion is located and which kind of lever is implemented in their arm.
- Taking their arm as an example (and by using abstraction) they learn to develop and to construct a model from which the lever principle can be deduced by measuring the involved forces.
