This GEMS guide, for grades four to eight, features ten learning stations designed to enliven student curiosity in a wide diversity of scientific fields. Using hand lenses and microscopes, students observe, record, and investigate water drop magnifiers, fingerprint ridges, dollar bills, color printing, fabrics, salts, sand, kitchen powders, insects, spiders, brine shrimp, and pond life. The 3Discovery Quilt is one of several options for students to sum up their discoveries. Many of the learning station activities make excellent connections to other GEMS units. This guide represents an innovative partnership between GEMS and the Microscopy Society of America which sponsored its development.
