Samantha Reif, professor of geology, helped Brownie Troop #6153 of the Athens/Cantrall area this week to earn their Brownie “Space Science Adventurer” Badge. She taught the girls how create a constellation viewer, introduced them to planet squishies Jupiter and Pluto, taught the girls about moon phases using Oreo cookies and set up her telescope at Cantrall Elementary School so the girls could see the moon up close. The troop is led by Amy Chernowsky, instructional designer.
