In this activity about magnetism (page 4 of the PDF), learners will experiment with magnets and different objects to find out that not all metals are attracted to magnets.

In this physics activity, learners will explore buoyancy.

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 activity about magnetism (page seven of the pdf), learners experiment with magnets to better understand how magnetic fields work.

In this chemistry activity, learners explore chemical reactions and their effects, including the kind of reaction in the human body that makes people burp!

In this activity about magnetism (page 13 of the pdf), learners will experiment with magnets to explore how water and other liquids affect the strength of magnetic fields.

In this chemistry activity, learners will learn how to make their own pH indicator using cabbage leaves, and then test common household items with their homemade indicator.

In this activity, learners will create glitter bottles with adult supervision. These are a fun way for little ones to practice observing and making comparisons.

In this chemistry experiment, learners get to make a very bizarre substance using corn starch and water. Is it a solid? Is it a liquid? Or is it a different kind of substance entirely?

In this activity about transfer of energy, learners get to build their own catapult using nothing more than a plastic spoon and some tape.

In this activity, learners will explore the chemistry of cooking. They will learn about--and observe--the Maillard Reaction as they make their own browned butter.

This is an online activity about what would happen if we could travel at or near the speed of light.

In this activity about magnetism (page 15 of the PDF), learners will explore how opposite and similar magnetic poles affect a swinging (pendulum) magnet.

This is a chemistry lab activity about solutions (page 6 of the PDF). Students make a limewater testing solution for carbon dioxide and explore the concepts of solubility and precipitates.

This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.

In this physics activity (page 14 of the PDF), learners gain a better understanding of how friction and mass affect objects by comparing the rotational inertia of raw and hard-boiled eggs.

This is an online game about stopping distance. Learners choose one of three vehicles and one of three speeds.

In this physics activity (page 2 of the PDF), learners will explore the concept of thermal conductivity and learn the differences between high and low thermal conductivity.

In this physics activity (page nine of the pdf), learners use balloons to explore how a rocket works. It is suggested they also work to see how they can alter the velocity of the rocket.
