Learners follow the template to build and fly a paper helicopter.

Learners build pan pipes out of drinking straws by cutting them to different lengths. Then, learners make music by blowing across the straws and playing some well-known songs.

In this activity, challenge learners to keep an ice cube from completely melting in 30 minutes. Learners engineer a box or wrap to prevent an ice cube from melting.

In this engineering activity, challenge learners to make a "grabber" that can pick up trash. Learners use simple materials to create pinchers that can grab small items.

Everybody loves messy science, and Flubber is a favorite of both COSI employees and guests!

In this activity (16th on the page), learners play a variation of the "I Spy" game to explore color. Learners work in teams with each team assigned a color.

In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract

In this activity, learners make an electroscope out of a foam cup, straw, aluminum pie pan, thread, and foil. Learners use their electroscopes to test for static electricity.

In this optics activity, learners build an animation tool to make mini movies. When you spin a phenakistascope, the pictures move so quickly that your eyes and brain can't separate the images.

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

In this activity, learners build a switch to turn electrical circuits on and off.

In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.

In this activity, learners build a mini crank machine to make a bird "fly." This engineering activity introduces learners to automata, rotational motion, cranks and cams.

In this physics activity, challenge learners to lift a book with just air using a plastic bag and a straw. This activity demonstrates compressed air and forces.

In this activity, learners will explore their center of gravity.

In this physics activity (page 3 of the PDF), learners will see firsthand that air takes up space and has pressure by attempting to inflate a balloon inside of a bottle.

In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.

In this math activity, learners pretend there is a special store that lets you pay for toys by their weight in pennies.

In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.

With a magnet, iron fillings, and a bottle, you can create a cool demonstration about magnetic lines of force: the fillings will arrange themselves within the magnet's magnetic field.
