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

Learners cut and fold a paper helicopter from the template in this PDF. They practice twirling the helicopter and observe what happens as they modify their tries.

In this activity, learners engineer a flying glider using paper hoops and a drinking straw.

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

In this activity, learners work in teams to construct and test fly drinking straw rockets. Learners explore how changing the rockets' fins affect flight distance.

This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.

Learners follow the template to build and fly a paper helicopter.

Learn how to make and fly a paper helicopter! This simple activity includes a template (for the copter "blades") and instructions for folding, flying, and testing designs.

In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.

In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.

Learners act as engineers and design mini submarines that move in the water like real submarines.

Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

In this physics activity, challenge learners to make a rubber band-powered spool racer. Demonstrate principles of motion as well as potential and kinetic energy.

In this activity, learners explore density and buoyancy as they design and construct rafts.

In this activity, learners engineer a paper helicopter that spins to the ground when dropped.

In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.

This assortment of mathematical games can be played while traveling.

In this activity, learners make and test fly paper helicopters. Learners use templates to create paper helicopters and then take take turns flying them in the air.
