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.

Push Me a Grape
Source Institutions
In this physics activity, learners experiment with the attractive and repulsive power of magnets.

Sound Dampeners
Source Institutions
In this activity, learners will experiment with water- and air-filled balloons as a way of dampening sound before it reaches their ears.

Liquid Lava Layers
Source Institutions
In this activity, learners explore the concepts of density and basic chemical reactions as they create a homemade lava lamp effect using water, oil, food coloring, and Alka-Seltzer tablets.

Gravity Fail
Source Institutions
In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

Gassy Lava Lamp
Source Institutions
In this activity, learners use oil, water, food coloring and antacid tablets to create a bubbling lava lamp. Use this activity to introduce concepts related to density, hydrophobicity vs.
Currently Working: Testing Conductivity
Source Institutions
Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.

Build a Rocket - and a Launch Pad!
Source Institutions
In this activity, learners construct a rocket powered by the pressure generated from an effervescing antacid tablet reacting with water, and build a launch pad for their rocket.

Make a "Mummy"
Source Institutions
The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

Sink It
Source Institutions
Learners classify a variety of objects by their characteristics. They then design an experiment to determine which objects float or sink in water and add this characteristic to their classification.

Periscope
Source Institutions
In this activity, learners construct a device that allows them to look over ledges or around corners.

Burn a Peanut
Source Institutions
In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut.

Air Pressure
Source Institutions
In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

3-2-1 POP!
Source Institutions
In this physics activity, learners build their own rockets out of film canisters and construction paper.

Bridge the Gap
Source Institutions
Learners work in groups to construct bridges using stale marshmallows and toothpicks.

Pearlescent Pigments
Source Institutions
This is written as a display, but can easily be adapted to a hands-on activity. Learners observe and shake containers of shiny liquids.

Heating and Cooling of the Earth's Surface
Source Institutions
Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.

Plankton Feeding
Source Institutions
This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

Launch Altitude Tracker
Source Institutions
In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.
