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

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 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.

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 activity, learners explore the history, design and motion of spinning tops. Learners work in teams of "engineers" to design and build their own tops out of everyday items.

In this activity, learners build helicopters and launchers using wooden dowels and scrap paper. Use this activity to explore rotational motion and kinetic and potential energy.

In this physics activity, learners will gain a better understanding of how friction, inertia, and mass affect objects.

In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi

In this physics activity, learners construct a small-scale version of a classic carnival game.

In this activity, learners are challenged, using everyday objects, to create simple machines to complete specific tasks.

In this design challenge activity, learners build a tower that’s at least 12 inches high with two or more parts that move (spin, sway, or flap) in the wind.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

In this demonstration about force and motion, learners will explore the forces that affect a pendulum A simple model pendulum comprised of a ball and string demonstrates how pendulums work as well as

This is an activity about circular motion. Learners will explore the laws of motion and force by observing circular motion.

In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

In this activity, learners explore how the pendulum has been a reliable way to keep time for centuries.

Learn how to make and fly a paper helicopter! This simple activity includes a template (for the copter "blades") and instructions for folding, flying, and testing designs.

In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.
