We put it in a tote inside at the science fair. Not sure how long it would hold up outside.

Hydropower

Q: How long does it take to build?

Thank you for your question. It depends on the model and the building speed of the user. There are 6 different models that you can build with varying levels of difficulty. You can learn more here: http://www.thamesandkosmos.com/products/manuals/624811_hydropower_manual.pdf

Q: Will a 6 yr old be able to use this?

With some oversight, yes. It is an assembly where there are instructions that need to be followed, with some explanations and other tips in written form, so it is helpful if the assembler can read, understand, and fully comprehend. Once assembled, there are gearing changes and other adaptations that can be done by a 6-year old after he/she has a basic understanding of the actual workings of the generator assembly. We used this set for a 7th grade science fair experiment, so the assembly was 100% done by my then 13-year old son. But I followed along out of curiosity and I think it could be assembled by a younger set of hands with adult supervision.

Q: The led broke on this contraption, and attaching a new led doesn't seem to work. i tried a 3ohm bulb with no success. suggestions?

When mine broke, I thought it was the LED bulb, but it was actually the motor. It is possible that is what is wrong with yours.

Good little kits

Used this with groups in my class for a renewable energy week. The children are 6 and 7 so needed adult support to use it but end product was good. Led was broken before it got used which was annoying and the instruction booklet was deadly when it came to papercuts but apart from that it was a good purchase for the kids

A lot of parts not provided but required.

Several of the experiments require parts that are not provided and some constructions fall apart right away.

be warned water wheel is very poor design and quality

this set should be great for the money sadly i was very sad to see that the water wheel is so flimsy and badly made it ruins the set the water wheel is very very thin clear flexible plastic its not rigid and is clear it looks nothing like a water wheel, the cogs and gears that make up the rest of the set are fine good quality but the main part the water wheel is really bad as a result i think this set is expensive and my 10 year old son is disappointent whith the water wheel which is the main part, its a shame the water wheel is so bad however goods where delivered on time in good condition

Disapointed

We bought this for our 12 year old grand daughter for christmas who is interested in science, on christmas day we set about putting together one of the projects it was very disapointing for myself as the grand father for having her such a poor qualiy present,and for her on such sn important day trying to put something together with poor quality parts.
