Thames & Kosmos Hydropower Science Kit | 12 Stem Experiments | Learn About Alternative & Renewable Energy, Environmental Science | Parents' Choice Recommended Award Winner

I've selected this item for experiments. When I've got it, I revealed more options for exepriments that it was described on teh site. So, I was surprised! Very good and inetersting item. I'd recommend this item to pupils and teachers.

I bought 2 Thames & Kosmos Science kits for a bright 8 year old nephew whose into Science; he was very excited to receive them. I never followed up to ask details about the quality and usage, but friends have said that Thames & Kosmos kits are the better ones of the choices out there.

I purchased this product for my daughter's science project (she's 12). She was able to put it together quickly and thankfully so because the instructions have no words - only pictures. It lasted for a few practice runs then the light stopped lighting up. We took it completely apart and put it back to together with a slight adjustment to one of the washers and it was working great. The class and her teacher were impressed. It's worth the money if you are using it for a project.

We love Thames & Kosmos kits to educate our son with alternative energy options.

I like the concept, but to be honest when we built the waterwheel the gears did not line up properly so the part with the generator doesn't make contact with the other gears. Light only lit up half the time. So overall, I am not impressed with the performance based on the cost.

Great set! Easy to put together and so far everything has worked as intended

Bought for science project on energy- worked beautifully!

Hard to put together, not stable. Worst thing? Didn’t work. When you spin hard with your finger just the rod, it does light up for a sec but even under a super strong tub faucet, nothing. What a waste of money.
