Review: A good collection of educational games is available at NASA Kids Club. There are five skill levels available, skill level one being suitable for even pre-schoolers. The games are varied in content and graphics. There are games about space, atmosphere, NASA missions and satellites, math and even healthy eating. Some games like Buzz Lightyear have accompanying educational worksheets as well. There is music though but there is an option in all games to turn it off.
Suitable for ages: 4-13
