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

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 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.

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 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 watercraft engineering and sailing.

Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

In this activity, learners use ABS pipe and an air leaf blower to make a strong shooting machine.

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

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper
