Turning the Air Upside Down: Warm Air is Less Dense than Cool Air
Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

Three Bean Salads
Source Institutions
This game teaches ratio and proportion by having learners make "salads" that combine three types of beans in different combinations.

Patterns and Functions: Fill 'er Up
Source Institutions
In this math lesson, learners predict, interpret, and sketch graphs of functions related to the shapes of bottles. A measure of water is poured into a container.

Special Effects: Titanic and Beyond
Source Institutions
In this activity, learners investigate how geometry plays a role in perspective.

Signs of Life
Source Institutions
In this activity, learners examine photo images of Earth taken from space, and attempt to identify and explain some of our planet's geological features.

Fantastic Plastic
Source Institutions
In this activity, learners investigate the properties of plastic bags. Learners find out what happens when they slowly push a pencil through a plastic bag filled with water.

Kepler Paper Model
Source Institutions
In this activity, learners build a paper model of the spacecraft and photometer (telescope) used during NASA's Kepler Mission.
Balloon Surprise
Source Institutions
In this activity, learners discover a trick to release the air out of a balloon without popping it.

Weather Stations: Winds
Source Institutions
In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.

Rates of Change: Bottles and Divers
Source Institutions
In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.

Football
Source Institutions
In this math activity (Page 10 of the Play Ball! PDF), learners play a game of "football" and analyze the results of the game.

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.

Vibrating Pennies
Source Institutions
Conduct a simple experiment to explore how temperature changes can make things expand or contract.

Xenosmilus
Source Institutions
Learners imagine they are paleontologists in Florida, where they find (remove from envelope) paper "fossils" of some unknown creature, only a few at a time.

Coffee to Carbon
Source Institutions
In this activity, learners place cards featuring biological structures in order by their relative size from largest to smallest.

Straw Rockets
Source Institutions
In this activity, learners will create unique rockets. Each rocket will be powered by air as the learner will blow into a straw and watch their rocket fly.

Shrinking Coin
Source Institutions
In this demonstration, learners attempt to get a large coin through a small hole, the size of a smaller coin.

Test the Finger Wrinkle Hypothesis
Source Institutions
Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?

Helicopters
Source Institutions
In this activity, learners will observe how air interacts with a paper helicopter. Learners will test different variables of weight, size, and shape.
