The Explore the Nervous System section highlights this site, a 60 part tutorial on the brain, spinal cord, nervous system, neurons, sensory systems, neurosystems, neuroscience methods, and the effects of drugs on the nervous system. Marked by clear, concise language and colorful illustrations, these tutorials offer a set of activities in thirteen categories, including nervous system modeling, brain games, sleep and dreaming, and biological rhythms. A series of annotated pointers to other related Internet resources and a bibliography of both online and print sources round out this information-rich site. NASA's well known High Energy Astrophysics Learning Center has created an astronomy site just for kids. It also includes a glossary with brief explanations of astronomy-related terms.
Content is written at two reading levels.
Each issue explores a scientific topic such as trees, skeletons, or ice and snow. Activities that complement the theme of each issue promote hands-on scientific research by children. Dragonfly promises to be a step forward in interactive learning for elementary school science. Included are such items as a glass eye, a silicon cochlear implant, a hip and a knee, among others. Information is aimed mostly at young children, but Yorick should also be of interest to older users.
