In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

In "Exploring the Solar System: Mars Rovers," participants learn about how scientists and engineers use robotic rovers and other vehicles to explore distant worlds, and experience some of the challeng

Learners examine the manufacturing process while they make picture frames from cereal boxes.

In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

In this activity, learners explore how rescue devices are designed to aid professionals during emergency situations.

In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.

Play with your food while learning about engineering! Build a spaghetti bridge, then test its strength by piling on the marshmallows, raw spaghetti, raw linguine and coins.

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

In this engineering activity, challenge learners to invent a water filter that cleans dirty water.

In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

In this activity, learners explore how engineers design tire treads to increase safety and reliability.

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 how spring scales work and how they are used for non-exact weight measurement.

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.

In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.

In "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can
