is a geography program for students in grades 3 to 8 that uses NASA space images and trivia questions. It provides insight into land, water and air features visible from space. The information presented is basic, but it is made interesting by actual photographs of surface images and by trivia questions on each subject. It also includes a space section that lets you learn about the continents and oceans, chart Antarctic sea ice growth, track a hurricane, and see the Sahara's desert growth over a decade.
The program can be timed or self-paced, and scoring is provided at the end of the exercises.
