Balloon Isometrics
Source Institutions
In this chemistry activity, learners will explore the concept of entropy. When learners stretch and unstretch a balloon, they will notice a change in temperature.
Clues About Clouds
Source Institutions
In this weather activity which requires adult supervision, learners will get a chance to make a cloud right here on Earth!
The Pulse of Gravity
Source Institutions
In this astronomy activity (page 3 of the PDF), learners will examine the effects of gravity on a person’s pulse and explore how gravity can differ from planet to planet.
Rollback
Source Institutions
In this physics activity (page 10 of the PDF), learners will make a can that will roll back after it has been rolled away to observe the interactions of kinetic and potential energy.
What Goes Up...
Source Institutions
In this activity about gravity (page eight of the pdf), learners will very simply explore how gravity affects objects using balls and toys.
Spaghetti Bridge
Source Institutions
In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.
Vibrant Cords
Source Institutions
In this activity, learners will explore how the voice works and feel the vibrations produced by vocal cords.
Two Lenses in One
Source Institutions
In this activity about light, learners explore how water can refract light and change the way they see things.
Density Stacker
Source Institutions
In this physics activity (page 8 of the PDF), learners will explore the property of density.
Owl Pellets
Source Institutions
In this activity (page 7 of the PDF), learners will investigate the contents of owl pellets. Learners will discover how owls digest their food as well as the kind of animals they eat.
Magnet Races
Source Institutions
In this physics activity (page 4 of the PDF), learners will explore how similar magnetic poles repel one another. They will rely on linear induction to race magnets around a simple course.
Static Spoons
Source Institutions
In this physics activity (page 6 of the PDF), learners will explore how static electricity affects surrounding objects.
Bones
Source Institutions
In this health activity (page 5 of the PDF), learners will explore a unique connection betweeen the bones of the body.
Spit Test
Source Institutions
In this biology activity (page 8 of the PDF), learners will explore how saliva assists in the beginning of the digestive process.
Peanut Butter and Jelly Robot
Source Institutions
This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.
Limewater
Source Institutions
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.
Paper Airplane Contest
Source Institutions
In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.
Comparing Crystals
Source Institutions
In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.
Chemical Reactions in Your Mouth
Source Institutions
In this chemistry activity (page 5 of the PDF), learners will see that chewing is more than just the crushing up of food; there is actually a chemical change going on at the same time.
COSI's Flubber Recipe
Source Institutions
Everybody loves messy science, and Flubber is a favorite of both COSI employees and guests!
