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.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

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.

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

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 three-part activity, learners use paper to explore Bernoulli's Principle — fast-moving air has lower pressure than non-moving air.

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.

In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

In this activity, learners build their own rockets from paper, coffee stirrers, and tape. Learners discover that when anything flies, air pressure is always involved.

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.

Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.
