In this activity, learners use ABS pipe and an air leaf blower to make a strong shooting machine.

This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.

In this activity (located on page 7 of PDF), learners explore how Silly Putty was first invented and then attempt to make a batch of their own.

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.

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

In this activity, reuse two-liter bottles to create bowling pins. Learners practice math skills and develop a concept of verifying answers, while bowling and keeping score.

Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

In this activity, learners model ancient lunar impacts using water balloons.

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

Build your own version of a favorite carnival game, in which a marble races down a maze consisting of rows of nails.

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

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.

In this math activity (Page 17 of the Play Ball! PDF), learners play a game of "baseball" and analyze the results of the game.

In this math game, learners solve a mind-twisting puzzle using dominoes. Use this activity to help learners practice counting, adding, and solving problems.

In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.

Learners build a pendulum from a yo-yo, and then design their own experiment to determine what affects the pendulum's period of swing.

Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.

In this physics activity, learners assemble and/or investigate a pendulum "snake." Several large steel hex-nuts are suspended on strings of successively increasing length to form a series of pendulums
