COSI

In this activity, learners will create beautiful greeting cards by marbling with shaving cream and food dye. They will explore the chemistry behind the art of marbling.

In this activity about magnetism (page 17 of the pdf), learners experiment with magnets, exploring the concept of diamagnetic materials by seeing how a grape reacts to a magnetic field.

In this activity about light, learners explore how water can refract light and change the way they see things.

In this activity, learners make a solar oven. Learners witness the awesome power of the sun to make a yummy treat--a chocolate chip cookie!

In this chemistry activity (page 3 of the PDF), learners will observe a chemical change, specifically what happens to iodine when it is applied to ripe and unripe apples.

In this physics activity (page 8 of the PDF), learners will explore the property of density.

In this physics activity (page 2 of the PDF), learners will construct their own walkalong glider. They will explore how air, though invisible, surrounds and affects other objects.

In this activity (page 6 of the PDF), learners will observe both a chemical and a physical change.

In this physics activity, learners explore how sound is created by vibrations.

In this activity about gravity (page 6 of the PDF), learners will come to understand how all objects will fall at the same rate, but that air will slow things down.
