St. Edmund Prep Earth Science Class Studies Geodes

Students at St. Edmund Prep High School recently learned about geodes in the Earth Science class. Each student held their sphere or oval shaped rocks and waited for their turn to break them open. With the help of science teacher Mr. Mancuso, students used a soil pipe cutter with a roller chain of wheels to break open the Keokuk geodes. Once opened, students examined the crystals and minerals found inside the geodes. Every geode is unique inside and their minerals and crystal formation can only be discovered when cracked open. The students looked for the special features their geode possessed such as size, color, crystals, and minerals. In addition to the science course given at St. Edmund Prep, students have the opportunity to join the mineralogy club. Mr. Mancuso and his club members are currently planning a spring mineral fair where various minerals will be displayed and may be purchased.
