This brief video clip demonstrates how to create a hovercraft from simple materials. Toward the end of the clip, the students in the video explains the science behind the hovercraft's motion (reduced friction). Students are encouraged to continue the experimentation on their own by changing variables in the design of the hovercraft.

In this activity, students will analyze a video featuring an airplane on a string. The tension in the string can be read from an on-screen scale, timing measurements can be made from the frame-counter, and the angle of the string can be determined from an overlaid protractor. While this doesn't seem like enough information, it's actually enough to allow students to calculate the angular and linear velocity of the plane, the mass of the plane, the radius of its circular path, and the length of the string. It is an engaging problem that forces students to think clearly about some concepts that they frequently find confusing, like tension, circular motion, and centripetal acceleration.

This is a book containing over 200 problems spanning over 70 specific topic areas covered in a typical Algebra II course. Learners can encounter a selection of application problems featuring astronomy, earth science and space exploration, often with more than one example in a specific category. Learners will use mathematics to explore science topics related to a wide variety of NASA science and space exploration endeavors. Each problem or problem set is introduced with a brief paragraph about the underlying science, written in a simplified, non-technical jargon where possible. Problems are often presented as a multi-step or multi-part activities. This book can be found on the Space Math@NASA website.
