Here’s what NASA says:
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.
