In this astronomy activity (page 3 of the PDF), learners will examine the effects of gravity on a person’s pulse and explore how gravity can differ from planet to planet.

This is a great activity about human energy production. Learners will work out with a clothespin to investigate why hockey players jump on a stationary bike after an intense game.

To understand how skaters turn in midair, try this little experiment! Individuals can do this activity alone, but it works better with a partner.

This trick from Exploratorium physicist Paul Doherty lets you add together the bounces of two balls and send one ball flying.

This is an activity about reaction times. Just how quickly must an NHL goalie respond to save a shot, and how does your reaction time compare?

In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment.

You may have tried to throw a curveball or a slider, or even a screwball, with an ordinary baseball and found it difficult to do.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

When baseball was in its infancy, the ball had plenty of bounce. Today's baseball may not seem to have bounce to it at all; if you drop a ball on the field it won't bounce back.

In this movement and measurement activity, learners jump as far as they can three times, and compare their longest jump to the longest jump of their friends, classmates and/or family members.
