4 in 1 Solar Power & Electric Motor STEM Kits,Science Experiment Projects for Kids Beginners,Electronic Assembly Solar Powered Toy Kit,DIY Educational Engineering Experiments for Boys and Girls

The media could not be loaded. I bought this kit for my child's science class and would recommend the product. The models were straightforward to assemble (for me), but my 10 year old needed quite a bit of assistance in putting the pieces together. All models worked well, the size of the models made them easy to handle, there was variety in the models to help understand energy conversions from solar to electrical and electrical to motion, chemical energy to electrical, electrical to motion and wind to motion. The solar buggy also helped in illustrating how the drive mechanism in a car works. It was a lot of fun putting the models together. My child enjoyed playing with the models and learning about energy conversions.

Bought to assist for my son’s science fair project. We put together a battery powered car and a solar powered. Pretty easy to assemble and cars worked great. Not a ton of instruction for all of the types of cars you can build with the kit.

I love this product even for my high school students. Enhances creative skills. Highly recommended

Cells can't power a motor

These worked perfectly! They were purchased for a 5th grader for student projects STEM.

Great item. Delivered on time

This review is for the 4 in 1 Solar Power & Electric Motor STEM Kits.I want to help my grandchild learn about solar. This kit contains 2 solar projects and 2 projects requiring 2 AA batteries (not included).It's a bit smaller than I expected, but everything works and all the parts and pieces fit. So - all is well!Am I a satisfied buyer? Yes. Would I recommend this kit to a friend? Yes.

3 hours struggling with tiny tiny screws & parts to assemble the car & the fan. Providing solar to them for a day, neither work! I bought 2 & returned the boxed one. I don’t recommend these for kids or senior citizens!
