CYOEST DIY 5 Set STEM Lab?Science Kits Toys for Kids Electric Motor Assembly Solar Powered Kit DIY Educational Engineering Experiments for Boys Girls 5 Sets

Our original intention in designing this set of toys: Are there any appropriate toys for teens to play with? How to keep them away from screen games or TV? We designed the assembled toys for them to inspire young inventors to motivate their science enthusiasm and build their own works by themself. Children are happiest with the process of hand-brain combination.“Wow, an awesome toy made by myself!” They are not just toys. We also intend to enhance children's Science skills through hands-on activities. Different products embody the application of different scientific knowledge and simple principles. Features: 1.Wind Power Car and Electric Glider Airplane The product makes children know the application of airflow reaction force and enhance the ability to operate. 2.Solar panel fan and Solar mini car The photoelectric conversion material of solar panels generates current in the sunlight. The current drives the fan blade to rotate and the car to move. 3.Hand crank generator The product involves the physical knowledge of energy conversion(mechanical energy-electric energy-light energy).When Shake the handle forcefully and quickly, the current generated by the high-speed rotating motor lights up a LED. Package including: 1xSolar Mini Car 1xSolar Panel Fan 1xHand Crank Generator 1xWind Power Car 1xElectric Glider Airplane English manuals Message: Scientific exploration is full of difficulties and unknowns. As long as you dare to try and explore, you exactly are a little inventor.Little children should operate under the guidance of adults.
