In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.

In this activity (on page 134 of the PDF), learners explore reaction time.

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.

In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

In this robotics activity, learners drive a remote-controlled car through a course to learn the challenges faced while trying to operate a planetary rover.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In this activity, learners explore how distance can affect the way we perceive the size of an object.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

In this activity, learners play a series of simple games to investigate navigation without visual and sound cues.

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.
