See a whole new world! Many "invisible" things spring to life under a microscope--and these hands-on experiments show kids how to glimpse this universe. Microscope basics cover microtomes, wet mounts, and smear and squash slides. Take a close-up look at animal bone marrow and fur; the icky slime on your teeth in the morning; and pollen and grass. Try a "bright idea" for examining a burnt-out lightbulb. Do a "flaky experiment" with a snow crystal. Learn how microscopes help solve crimes. Dozens of photographs and funny drawings, with science fair suggestions, encourage children to embark on microscopic explorations.
