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

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

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.

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.
