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.

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.

In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.

In this activity (4th activity on the page), learners test to see if saliva is necessary for food to have taste.

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

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

In this activity about light and perception, learners discover how a flash of light can create a lingering image called an "afterimage" on the retina of the eye.

What does it mean to be alive? Is a cactus alive? Is a seed alive? Is the air we breathe alive? What are the necessary characteristics?

In this experiment, learners float colored ice cubes in hot and cold water.

In this activity, learners will train to develop upper and lower body strength in their muscles and bones by performing body-weight squats and push-ups.

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 activity, learners explore accuracy and precision.

In this activity, learners design a therapeutic agent to image and/or cure various diseases in the respiratory system.

In this activity, learners complete simple exercises to investigate the relationship between force, area and pressure and their effects on materials.

In this activity, learners will write a secret message that only their friends will be able to read.

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

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

In this activity, learners explore computer programming and the impact of computers on society. Learners build and test a program to turn a light on and off using an Arduino board.

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,
