Paper Plate Education "Serving the Universe on a Paper Plate," boasts the motto here. This site cleverly reduces complex notions down to simple explanations that kids of any age can understand. Nearly 90 projects use ordinary paper plates to demonstrate concepts from astronomy, math, geography, and other subjects. Create a platisphere to show the position of the circumpolar stars for any given date and time. Construct a 3D (or 3-plate) model of the Earth's core. Combine astronomy and cookies to make Oreo moon phases. Learning delivered on a paper plate never tasted so good. (in Social Science)
