Description: Material and Size: Hydroelectric power generation science experiments set is made from pp materials for durability and safe during use. The assembled model measures 24cmx18cmx21cm, perfectly sized for young hands to manage comfortably Interactive STEM Experience: Encourage your child's interest in science and technology with this interactive STEAM project that combines fun with education Educational Tool: Designed to satisfy children's curiosity and enhance their overall skills. By assembling the kit themselves, kids can learn about the principles of hydropower generation Understanding Hydropower Principles: This science experiments kit provides a simplified demonstration of how hydropower works by converting water energy into electrical energy. It mimics a large system where potential energy from water is conversion into mechanical energy by a turbine and then into electrical energy by a generator Package Includes: The experiment set contains all the necessary materials to conduct a variety of experiments. Engaging and easy-to-use activities provide hands-on coverage of key experiments skills Specification: Material: PP   Size Chart: 24cmx18cmx21cm/9.45inchx7.09inchx8.27inch Package Includes: 1 Set Hydroelectric Power Generation Science Experiments Note: Please allow slightly errors due to manual measurement and different monitors.
