The suggested subexperiments are ideal for introducing the basic chemical subject of material separation based on the current topics “environment, waste, and recycling." Subexperiment 2 would be of particular interest for a physics class. This subexperiment allows students to verify their prior knowledge of electricity and magnetism, using eddy currents and their effects as an ex-ample. If students lack this prior knowledge, the teacher should make sure to discuss these subjects before or after the experiment. These experiments can also be used in an interdisciplinary approach, e.g., within the context of an environmental project. The materials supplied allow eight groups of students to conduct the experiments simultaneously.

The experiment comprises two subexperiments:
• Separation of a mixture of solid substances
• Principle of the separation of aluminum from other non-ferrous metals

• Observe the safety information in the instructions as well as the applicable safety guidelines for your school.
• All materials mentioned in the instructions will have to be purchased directly from commercial sources.
