Students design and create their own air-powered rockets, in this hands-on activity.

In this activity, learners build a carousel toy that spins when pushed down.

In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

Learners construct an electricity-generating wind turbine out of a plastic bottle.

In this activity (on page 2 of PDF under GPS: Roller Coaster Design Activity), learners will use food cans of many different properties (sizes, shapes, and weights) and set two cans on their sides at

In this activity, learners discover that some things only stand up while they are spinning.

In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

In this demonstration/activity, water streaming through holes in the bottom of a suspended soda pop can causes the can to rotate.

In this activity, a spinning bicycle wheel resists efforts to tilt it and point the axle in a new direction.

In this activity, learners use a laser pointer and two small rotating mirrors to create a variety of fascinating patterns, which can be easily and dramatically projected on a wall or screen.

In this activity, learners explore how wind energy can be generated on both a large and small scale.

In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.

In this activity (page 1 of PDF under SciGirls Activity: Pet Handedness), learners will construct a simple spinning top out of a circle of construction paper, a film canister lid, and a bamboo skewer.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

In this activity, learners are challenged to design and construct a windmill to harness the power of wind.

Learners cut and fold a paper helicopter from the template in this PDF. They practice twirling the helicopter and observe what happens as they modify their tries.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.
