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 activity, learners explore center of gravity, or balance point, of stacked blocks.

In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.

In this activity, learners explore how changes in fluid pressure affect the buoyancy of a Cartesian diver inside a plastic soda bottle.

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 use simple materials to create giant bubbles.

Did you know that a Slinky makes a handy model of earthquake waves?

In this activity, learners predict whether a ball on Earth or a ball on the Moon bounces higher when dropped and why.

In this activity related to computer programming, learners give directions to a "robot" (either an adult or another learner) and find out which instructions the robot is able to follow, and how their

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

In this activity, learners explore sound by constructing an instrument toy that buzzes when you swing it.

Everybody loves boomerangs! In this activity about force and motion, the learners will experiment with boomerangs and explore how they work. This is a great activity to get learners up and moving.

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.

In this activity, learners investigate the reflective properties of light and mirrors as they make a kaleidoscope.

Design and create an optical illusion toy that makes two pictures appear to become one. This is called a thaumatrope and will allow the learner to investigate the phenomenon of persistence of vision.

In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

In this activity, learners will use their chosen material to build the tallest tower possible in under three minutes. This activity uses problem solving and fine motor skills to challenge learners.

In this activity (26th on the page), learners construct an easy-to-build device and test motor learning.

In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.
