Which science fair project do you think I should use?
And how can I test them in different ways, and how many conclusions can I draw from each?
The first one demonstrates Newton's Universal Law of Gravitation. You place two dense objects on a piece of Styrofoam, and hang the Styrofoam from a string with low torsion strength. You place two other dense objects on either side, and the objects on the Styrofoam are attracted to the stationary objects (http://www.all-science-fair-projects.com/science_fair_projects/57/698/23efb02d4fd377a0750ea53cd8c70d4a.html)
The second one is building a solar furnace, which you can use to concentrate solar power in to one spot. You get small mirror chips, about 1 square inch each, and using silicon caulk and screws you attach them to a square board and adjust the mirrors so they all point at one spot, creating a focused beam of light (http://www.all-science-fair-projects.com/science_fair_projects/58/722/4bbd39cf1da0dc50650f7b1c241b24fd.html).
Which do you think would get me first place?
