Weight

Principle

The students observe the behaviour of a coil spring that is subject to various forces when different masses are suspended from it, and notice that the weight of the suspended masses leads to an elastic deformation of the spring and that the deformation is reversible. They then draw the conclusion that the extension of the spring is proportional to the force acting on the spring, thereby learning about the basic principles of Hooke's law.

Benefits

• Experiment guides are very easy to understand, especially for younger students
• Associated competences are directly linked to the experiments
• Curriculum compatible
• Fit for the future: implementation of tablets possible
