Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

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.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

Learners compare the properties of two balls that appear identical. One ball bounces, while the other ball "thuds." The “bounce” ball is made of the polymer polybutadiene (-C4H4-).

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this physics activity, challenge learners to make and race a balloon-powered car. Learners construct the body out of a paper cup, wheels out of wooden spools. and fuel tank out of a balloon.

In this engineering design challenge, learners build an air-powered spinning machine.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this activity, learners build helicopters and launchers using wooden dowels and scrap paper. Use this activity to explore rotational motion and kinetic and potential energy.

In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

In this physics activity, learners will gain a better understanding of how friction, inertia, and mass affect objects.

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.

In this physics activity, learners build their own rockets out of film canisters and construction paper.
