Explore the effects of gravity on a slowly falling object: a parachute you make out of plastic bags, string and stones.

In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.

Learners trace, cut out and fly a boomerang, outdoors or in a large indoor space.

In this math activity (Page 12 of the Play Ball! PDF), learners play a game of "soccer" and analyze the results of the game.

In this activity, learners construct a simple game to test their hand-eye coordination and steadiness of hand.

Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

In this math activity (Page 14 of the Play Ball! PDF), learners play a game of "basketball" and analyze the results of the game.

In this quick activity (page 1 of the PDF under SciGirls Activity: Extreme Sounds) about sound vibrations, learners will investigate which small objects, such as coins, hex nuts, or marbles, produce t

In this activity, learners make some music by constructing a kazoo out of a simple plastic drinking straw. Use this activity to explore sound, vibrations, and music.

In this activity, learners determine the shape of an unseen object by bouncing a ball off the object.

In this activity, learners explore the properties of paper by constructing and modifying paper airplanes.

In this activity, learners investigate how changing the center of gravity of a balloon affects how it travels. Learners fill a balloon with a little bit of water and insert into an empty balloon.

Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

In this activity (on page 2 of the PDF under GPS: Luge Activity), learners will construct a model hovercraft out of an empty spool and a piece of cardboard.

In this math game (Page 14 of the Are You Game? PDF), learners determine the probability of getting an even versus an odd product using the numbers on a regular deck of cards.

Learners make bell bracelets, place them on their wrists or ankles, and then dance to the rhythms and sounds the bells make. Many cultures use ankle or wrist bells to make music during dancing.

In this activity, learners will make a thaumatrope, an old-fashioned optical illusion that dates back to the 1820s.

In this physics activity about rotational inertia, learners use a spinning top made out of a bottle cap and a nail to explore how changing the axis of rotation affects how the energy is used.

In this activity, learners will create their own simple shadow puppets, and experiment with light and shadow while playing with them.

Build a glider that uses the same physics as a curve ball, for less than a dime.
