How is ecological energy produced? How does a fuel cell work and how can you use it to obtain hydrogen? Renewable energy sources will become the most important sources of energy in the future. Nine models and 28 experiments are used to demonstrate the production, storage, and use of electricity from natural sources such as water, wind, and solar energy. Powerful solar panels can be attached in various ways for universal use in the models. The High-Capacity Capacitor included in the kit is an energy storage system. The fuel cell visually demonstrates how water is split into two components – hydrogen and oxygen. This teaches children about the energy sources of the future and helps them acquire important skills. The lesson plan and methodological materials assist teachers in using the STEM Renewable Energy kit in the classroom.
