In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

In this activity, learners explore what makes a boat float and sink. They examine and test various objects to determine why objects float or sink.

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.

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

In this activity, learners build a stuffed-animal zip line. Learners hold a cord against a wall, hook a cute stuffed animal onto it, let the animal slide down, and records its travel time.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.

This activity (on page 3 of the PDF under GPS: Sailboat Design Activity) is a full inquiry investigation into design optimization.

This activity (on page 3 of the PDF under GPS: Roller Coaster Design Activity) is a full inquiry investigation into g-force and acceleration.

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

In this outdoor activity, learners use pegs (like tent pegs) and string or elastic to simulate drill sites and roads in Northern Canada.

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.
