Geologists rock, and they like to have fun while they learn, which is why someone who wasn’t as dumb as a rock invented these (2) compact STEAM Earthly Elements kits. Each has a set of (6) earthly elements, a magnifying lens/ruler, display tray and interactive STEAM guidebook. You pick: the Essential Rocks & Minerals kit with the rock classification chart, Mohs hardness scale chart and more; or the Genuine Fossil Collections with the geological time scale. Made in USA. Ages 8+. Rock on, Surpies.
