Rocket Science 101 is a free iPad app offered by NASA. The app is designed to help students understand how rockets work and understand the differences between the four types of rockets most frequently used by NASA. In Rocket Science 101 students can build all four rockets in a jigsaw-like activity then virtually launch their rockets. When the rockets are launched students see the timing of each stage of the launch from surface to orbit.
After playing with the four types of rockets students can try their hands at matching rockets to real NASA missions. In the challenges students read about a NASA mission then have to select the rocket that can carry the payload and travel the distance required to complete the mission.
Rocket Science 101 could be a good app for students in grades five through eight to use to begin to understand some basic physics concepts associated with space exploration.
