ScienceWiz Volcanic Rocks Collection includes 10 large samples, each about 1 inch in diameter. These ten rocks are displayed inside a tray encased inside a windowed, cardboard sleeve. The tray slides open like a matchbox. Included inside is a guide to the collection. Each volcanic (igneous) rock description links (QR code) to further information online, that includes videos, activities, animations and games. This collection includes an arrowhead made with obsidian, a volcanic glass.
