A Curriculum Recommendation!

Longtime readers will know that I'm a pretty vocal critic of the LASER science kits that have been thrust upon the schools, so it's nice to be able to make a recommendation: Prime Curriculum, put together by an outfit out of Reardan, Washington. Simple, direct, focused, oriented towards agriculture, I've done a couple of them and have found that they fit into my 5th grade classroom just about perfectly.

They're not meant to be the primary bit of science curriculum, but I think they're a great add-on. Anyone else using them?
