Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation about the different causes of glacial melt.

In this physics activity, learners will explore buoyancy.

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.

Learners use compasses to detect the magnetic field created by current moving through a wire. This is one of four activities learners can complete related to PhysicsQuest 2008.

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

Everybody loves bubbles, and this is the best bubble recipe ever!

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

This activity (on page 2 of the PDF under SciGirls Activity: Music and Sound) is a full inquiry investigation into sound frequency.

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

In this full inquiry activity (located on page 3 of the PDF under GPS: Kinetic Sculpture Challenge Activity), groups of learners will make predictions about which feature of a pendulum (mass, length,

In this activity, learners explore the unique challenges in transportation engineering, such as devising a method for skiers or hikers to get to the top of a mountain.

In this fascinating and fun experiment, learners use chemistry to identify a mystery powder and to solve a "crime," a process similar to that used by real forensic scientists.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside

Many common household cleaners are antimicrobials.

In this activity learners explore surface tension. Why are certain objects able to float on the surface of water and how do detergents break the surface tension of water?

In this activity about the heart (on page 22 of the PDF), learners examine sheep or chicken hearts to learn about the heart's structure and the flow of blood through the heart.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.
