Is it limestone? Pumice? Obsidian? Slate? The students worked in groups to observe rocks and minerals, compare their properties, and determine the names of the various samples they examined. They also learned plenty of facts about rocks and minerals from the slide show presentation given by a Cranbrook staff member.
Students enjoyed learning about static electricity and magnets on our last trip to Cranbrook. Balloons charged with static electricity picked up balloons like magic! Students also got a charge out of watching hair standing on end.
