From wind comes electricity. A 90-centimeter tall wind turbine anchored in the ground demonstrates to children aged 8 to 14 how climate-friendly energy conversion works. With the outdoor set, they generate usable energy that flows into a rechargeable battery. This energy can power flashlights and similar devices, as well as an electric car created from the wind turbine's gondola. What angle of the rotor blades is optimal for different wind strengths? Which location in the garden is the best? Here, they can easily experiment. This turns theory into practice and makes knowledge tangible. The age-appropriate instructions provide clear steps for easy assembly and experiments, while explaining important information about renewable energy and climate protection. A KOSMOS experiment kit that offers children an impressive insight into the world of energy conversion. How is electricity generated from wind? With KOSMOS's outdoor model, children can test it themselves. In no time, the 90-centimeter tall wind turbine is set up outside and anchored to the ground with stakes. The experiments on energy conversion can then begin. What tilt angle of the rotor blades is optimal for which wind strength? Just try it out. The energy generated charges a rechargeable AA battery for flashlights, remote controls, and more, and a small electric car can be built from the turbine's gondola, powered by the battery. The experiment kit's instructions not only show step by step how to correctly set up and adjust the wind turbine but also explain a lot of interesting facts about renewable energy and climate protection. A great introduction to the world of renewable energies for children aged 8 to 14.
