Great site enrique. Thanks
I've liked trading at American science & supply.
I guess Cold wants some suggestions and sources for an exhibition he can do from scratch.
You can get dowels & styrofoam spheres at any Michaels, hobby lobby or walmart. Many others will be getting the same supplies and making models of a few molecules.
However, you can make the models enteresting and get extra points because this is a politically hot topic. Model the sucrose and water molecules on one side. Model ethanol and carbon dioxide on the other side. Explain the process is done through fermentation and decorate the exhibit with ears of corn.
Since I am fond of math more than electronics, I would make an electrical exhibition that displays boulean logic. Two switches wired in parallel to a light is a logical OR. Wired in series it is a logical AND. A pair of 2-way switches creates a logical NAND.

Google Arvind Gupta toys and find his website where he described tons of easy to make models showing scientific principles
