Yeast Balloons: Can biochemistry blow up a balloon?
Source Institutions
Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon.

Earth Atmosphere Composition
Source Institutions
In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

Hot Cans and Cold Cans
Source Institutions
Learners apply their knowledge of heat transfer to design two cans - one that will retain heat and one that will cool down quickly.

Cave in a Cup
Source Institutions
In this activity (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then

How it is Currently Done
Source Institutions
In this quick activity, learners observe how wind creates ocean currents.

Wet Pennies
Source Institutions
Learners initially test to see how many drops of liquid (water, rubbing alcohol, and vegetable oil) can fit on a penny.

Find the Best Way to Clean Oil off Bird Feathers
Source Institutions
In this experiment, learners examine the way oil affects bird feathers and test different cleanup methods to find out which works best.

A System of Transport
Source Institutions
In this activity about the human heart (on page 5 of the PDF), learners work in teams to simulate the volume of blood moved through the circulatory system by transferring liquid into--and through--a s

Recycling Paper
Source Institutions
In this crafty chemistry activity (on page 2 of the PDF), learners make their own paper from used paper they may have otherwise thrown away.

Handwashing Laboratory Activities: Fingerprint Technique
Source Institutions
In this lab (Activity #1 on page), learners compare bacteria growth on two petri dishes containing nutrient agar: one that has been touched by a finger washed only with water and one that has been tou

Charge Challenge
Source Institutions
In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

Egg Drop
Source Institutions
In this activity, kids make and play with Ooze before testing the material in an egg drop!

Make a Prism
Source Institutions
In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

Comparing the Density of Different Liquids
Source Institutions
Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

Do Cities Affect the Weather?
Source Institutions
In this activity, learners explore clouds and how they form.

Weather Stations: Storms
Source Institutions
In this activity, learners test how cornstarch and glitter in water move when disturbed. Learners compare their observations with videos of Jupiter's and Earth's storm movements.

Hot Stuff!: Testing for Carbon Dioxide from Our Own Breath
Learners blow into balloons and collect their breath--carbon dioxide gas (CO2). They then blow the CO2 from the balloon into a solution of acid-base indicator.

Ice Cream
Source Institutions
In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

Push It Out
Source Institutions
In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

Copper Caper
Source Institutions
In this activity, learners conduct an oxidation experiment that turns old pennies bright and shiny. Learners soak 20 dull, dirty pennies in a bowl of salt and vinegar for five minutes.
