All About Rocks Mini-Lab
Rocks may be hard, but the study of them doesn't have to be! Grow sugar crystals. Make sandstone in your kitchen. Weather a rock until it's ready to fall apart. Scratch, streak, and smash them, all in the name of science! When you're done, mount your collection on the display card. Kit includes 8 rocks, sand, a magnifier and a booklet with 17 activities.
