Heat Speeds Up Reactions
Source Institutions
In this activity, learners investigate the effect of heat on a reaction.

Build a Battery
Source Institutions
Learners make a simple battery out of "sandwiches" of aluminum foil, pennies, and a salt water-soaked paper towel.

Oily Ice
Source Institutions
In this activity, learners experiment with the density of ice, water, and oil. Learners will discover that the density of a liquid determines whether it will float above or sink below another liquid.

Egg Osmosis: A four day eggsperience!
Source Institutions
Eggs are placed in vinegar for one or two days to dissolve the shells. Then, learners place the eggs in water or corn syrup and observe them over a period of days.

Kaleidoscope
Source Institutions
In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

Design a Lunar Rover!
Source Institutions
In this team design challenge (page 2-10 of PDF), learners design and build a model of a Lunar Transport Rover that will carry equipment and people on the surface of the Moon.

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

DNA Extraction
Source Institutions
Learners use a simple process to extract DNA from strawberries.

Shake It Up!
Source Institutions
Learners observe a sealed container holding a clear colorless liquid. They shake the container and the fluid turns blue. When allowed to sit for a few moments, the fluid turns colorless again.

Toy Chemistry
Source Institutions
In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.

Iron for Breakfast
Source Institutions
Did you know that some breakfast cereals are fortified with ferric phosphate, while others contain tiny pieces of reduced iron?

Get a Leg Up
Source Institutions
In this activity, learners experiment and collect data during a simulation of the fluid shifts experienced by astronauts' bodies in microgravity.

Light Combinations
Source Institutions
In this activity about magnetism (page 17 of the pdf), learners experiment with magnets, exploring the concept of diamagnetic materials by seeing how a grape reacts to a magnetic field.

Hollandaise Sauce: Emulsion at Work
Source Institutions
In this activity, learners follow a recipe to make hollandaise sauce. Learners discover how cooks use egg yolks to blend oil and water together into a smooth mix.

Bend a Carrot
Source Institutions
In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.

Having a Gas with Cola
Source Institutions
In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

Diaper Dissection
Source Institutions
This is written as a display, but can easily be adapted to a hands-on activity. Learners discover how all the parts of a diaper work together to keep babies dry and comfortable.

Micro Automata
Source Institutions
In this activity, learners build small animated toys that move.

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.

Lever Cowboy
Source Institutions
In this activity, learners build a figure that moves and "comes to life" when they pull its string.
