Getting the Dirt on Dirt
I couldn’t pass this up. I took fifteen credits of Soil Sciences classes in college, and was tickled to find the NASA “Soil Science Education Web Page” (ltpwww.gsfc.nasa.gov/globe/.) It’s a resource page for students with loads of information and activities for studying soils. It even has a “Soil of the Month” picture!
Studying soil is a great integrated science project, because it involves botany, biology, chemistry and geology. (It’s also one of the only educational activities you can do that gives you a legitimate reason to dig big holes in the ground, which, come to think of it, has a language arts tie-in with Holes by Louis Sachar.) If you and your students want to have the necessary appreciation for the ground beneath us, check this page out.
