Building Science Kit for Kids, 4 Sets Educational Engineering Toys, Stem Projects for Boys / Girls-Solar Windmill, Generator, Binoculars, Balance Bird

Our original intention in designing these toys: Are there any interesting toys for kids or teens to play with How to keep them away from screen games or TV We designed these toys to inspire young inventors to motivate their science enthusiasm. Kids build their own works by themselves in the process of hand-brain combination. 'Wow, amazing toys made by myself!" These are not just toys. We also intend to enhance children's STEM skills through hands-on activities. Different toys embody the application of different scientific knowledge and simple principles. Features: 1.Binoculars The toy makes children know the imaging principle of telescope. 2.Solar panel fan The photoelectric conversion material of solar panels generates current in the sunlight. The current drives the fan blade to rotate. 3.Hand crank generator The toy involves the physical knowledge of energy conversion(mechanical energy-electric energy-light energy). When kids shake the handle forcefully and quickly, the generated current lights up a LED. 4.Balance bird The toy involves the physical principle of gravity balance. Can you keep the bird stable just with it's beak Package including: 1xBinoculars 1xHand generator 1xSolar windmill 1xBalance bird Related tools (screwdrivers,scissors) and English manuals. These toys don't need any batteries. Message: Scientific exploration is full of difficulties and unknowns. As long as kids dare to try and explore, they exactly are little inventors. Little children should operate under the guidance of adults as wonderful parent-child interactive toys. Add it to your cart now! Refund if you are not satisfied for any reason.
