Effects of Solar Radiation on Land and Sea
Source Institutions
In this activity, learners explore the different heating properties of soil and water.

Burning Issues
Source Institutions
Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

Polishing Pennies
Source Institutions
In this experiment, learners try different liquids to see which ones clean pennies best. Liquids to try include water, lemon juice, cola, vinegar, and dishwashing detergent.

Squeeze the Stream
Source Institutions
In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects.

Make a Rainbow
Source Institutions
In this activity, learners will explore light and rainbows with this easy setup! Learners will only need a cup of water, some paper and a flashlight.

Eyedropper Hydrometer: Buoy your understanding of density
Source Institutions
Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

Great Steamboat Race
Source Institutions
In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

Hot and Cold
Source Institutions
In this chemistry challenge, learners discover that many chemical reactions involve heat loss or gain.

We all Scream for Ice Cream
Source Institutions
In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

Build Your Own Hydroelectric Generator
Source Institutions
Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

Sink or Float
Source Institutions
In this activity, learners explore and compare the buoyant properties of materials found in nature and in human-made materials.

Glow in the Dark Jello
Source Institutions
In this activity, learners will make homemade jello that glows under a blacklight. They will learn about quinine, an ingredient in tonic water that is fluorescent.

Pop Rockets
Source Institutions
Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

Ocean Currents
Source Institutions
In this activity, learners will explore how density is affected by temperature and how that can create currents.

Oil Spill Cleanup
This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

Ice Melt
Source Institutions
In this activity, learners will explore basic information about thermodynamics by experimenting with ice. Learners will compare ice melting rates on metal pans or plastic cutting boards.

Salt Crystal Garden
Source Institutions
In this activity, learners will explore saturated solutions and discover how crystals form.

Aluminum-Air Battery: Foiled again!
Source Institutions
Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.

Watercolor
Source Institutions
In this activity, learners will use chemistry to create a night sky watercolor painting. They will experiment to learn the effects of mixing crayon, salt, and lemon juice with water color paints.

Shake the Bag Ice Cream
Source Institutions
In this activity, learners will experiment with salt and ice in order to turn a bag of ingredients into ice cream.
