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 create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

In this chemistry activity, learners use guar gum to make slime. Use this activity to introduce learners to polymers, viscosity, and colloids.

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

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

In this water activity, learners discover ways to move water across the water table.

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.

Working in small teams, learners try to build a satellite that can float for at least five seconds in the marked area of a vertical wind tube.

In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

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.

Learners make their own paper using old newspaper. Learners can make their paper colorful by adding construction paper.

In this activity, learners explore clouds and how they form.
