MudWatt is worthy of the GEI Seal of Endorsement. Seeing the ‘Ah-ha moment!’ in my students’ eyes is priceless!

— Muhammad A., GA, GEI Reviewer and Teacher

MudWatt engages kids in STEM in a whole new way, using the power of mud! It harnesses bacteria naturally living in the soil beneath our feet to generate electricity! Kids experiment with different types of soil (and food from the fridge) to maximize their power output. The MudWatt Explorer App lets kids measure their power, track their MudWatt’s growth, and unlock an awesome comic book!

Comments from other GEI teacher reviewers

“I found the product easy to use and a wonderful example of the energy being produced from the soil. It also had a lot of options for experiments with resistors, LEDs, and various circuits. I think it is a good example to use when teaching on these topics!”

— Brent H., MD, GEI Reviewer and Teacher

“The provided experiments gave a great starting point. Further experiments would easily enhance what the students are able to do.”
