Thanks acs! I am proud of DS because he poured his heart into this project for at least two months after he decided which of his three (original) ideas to go with. They all sounded too complex to me (and to his teacher).
He built a hydro turbine and a generator to measure the amount of electricity produced by different shaped water channels. His hypothesis, based on Pascal�s Law, PRESSURE=FORCE/AREA, turned out to be incorrect. The results demonstrated Bernoulli�s Principle which states that a fluid must exit a narrow area at the same speed that it entered.
No one would ever accuse me of having �done� this project for him. DH did supervise the use of power tools and guided him throughout, as well as, dumped the 5 gallon buckets of water through the channels. However, the project was conceived, driven and produced by DS.
I finally found the link for the big regional competition which is next Sat. Bummer, registration deadline was this past Friday and had to be initiated by the school.
