While we are not huge fans of Oriental Trading Co. and all the hundreds of throw-away toys, we love some specific items found in the educational sections of their catalog.
This is one - posters on topics of alternative energy. Fabulous, cheap, full color posters with great language about each topic. Another item for the earth day learning kit. Big and bold, these would be great for any classroom.
Included - Hydroelectric energy, Solar energy, Biomass energy, Wind energy, Geothermal energy.
