NASA's "Touch the Earth" takes a multimedia approach to teach middle school students about the Earth's biomes -- areas on Earth with similar climate, soil and vegetation -- using sound and visual aids, tactile and colored graphics, large print and Braille. It was developed for Blind and Deaf users as well as students who learn best with a multimedia approach, and was published with the support of NASA Headquarters' Office of Earth Science Education programs.

Individuals can order a copy of the Touch the Earth tactile book from the National Federation of the Blind Independence Market. To access the multimedia elements, follow the links below.

A biome is a region of the Earth with a specific climate, plant and animal life, soil type, and topography that interact with each other. If one part of the biome changes, the other parts change too. The animals and plants may not be able to survive certain changes in the biome. Image & ASL Signing & Captioning > Image & Audio >
