This site from the Astronomy Department of Cornell University provides brief introduction to both solar and lunar eclipses. Links are provided for pictures and charts of the eclipses, and this is a good site to check out on the subject.

Kids learn about lunar and solar eclipses in the science of astronomy including the umbra, antumbra, penumbra shadows as well as total, partial, and annular.

This site explains the phases of the moon and an easy way to remember waxing and waning. Students have to explain a given phase to their classmates with a model.
