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!

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.

Make a Museum Collection at Home
Source Institutions
In this activity, learners will create their own museum collection using their favorite toys, drawings, or collection.

Falling Faster
Source Institutions
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.

Static Spoons
Source Institutions
In this physics activity (page 6 of the PDF), learners will explore how static electricity affects surrounding objects.

Paper Airplane Contest
Source Institutions
In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.

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.

All About Air
Source Institutions
In this activity, learners with explore the gases present in air. They will then build their own wind cannons and challenge family and friends to a friendly competition.

Balloon in a Bottle
Source Institutions
In this physics activity (page 3 of the PDF), learners will see firsthand that air takes up space and has pressure by attempting to inflate a balloon inside of a bottle.

You're Grounded
Source Institutions
In this engineering activity, learners test the stability of towers they build out of cups, discovering that structures with more mass in the base are more stable.

Hover Cup
Source Institutions
Is this activity concentrating on physical science, learners build their very own miniature hovercraft out of a paper cup. Using it, they can explore the concepts of friction and force.

Bottle "Tops"
Source Institutions
In this physics activity about rotational inertia, learners use a spinning top made out of a bottle cap and a nail to explore how changing the axis of rotation affects how the energy is used.

Weightless Water
Source Institutions
In this physics activity (page 5 of the PDF), learners will witness the effects of free fall by observing falling water, and will gain a better understanding of the concept of weightlessness.

Jumping Beans
Source Institutions
In this physics activity (page 3 of the PDF), learners will explore the concept of static electricity.

Flip
Source Institutions
In this amazingly simple physics activity (page 5 of the PDF), learners will explore how exerting a force on an object can give it kinetic energy and momentum.

Ziploc Digestion Simulator
Source Institutions
In this biology activity, learners recreate the process of digestion in a zip lock bag. A bit of soda pop added to some crumbled crackers approximates how acids in the stomach dissolve food.

Frosty Glasses
Source Institutions
In this activity, learners explore why frost forms. They create their own frost using a solution of ice water and salt in a glass.

Backyard Graphing
Source Institutions
In this math activity, learners will create a scale diagram of their backyard or other outdoor area on graph paper.

Balancing Act
Source Institutions
In this physics activity (page 6 of the PDF), learners will build a class 1 lever and hypothesize and test the distances two objects need to be placed from the fulcrum in order to balance.
