Learners use shop tools and various materials to construct a magnetic spinner and a compass.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.

In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

In this activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.

In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.

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 construct a device that allows them to view 2-D images in 3-D.

This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.

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 related to computer programming, learners give directions to a "robot" (either an adult or another learner) and find out which instructions the robot is able to follow, and how their

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

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

In this activity, learners build an old-fashioned paddle boat out of simple materials.

In this activity, learners explore the concept of friction and how ball bearings reduce friction.

In this technology activity, learners light up the room with electrifying play dough creations. Learners use conductive and insulating homemade play dough to build simple circuits.

Make your own "Dance Dance Revolution" dance pad! In this design challenge activity, learners work in teams to build a dance pad that lets you use your feet to sound a buzzer or flash a light.

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

In this activity, learners explore the concept of how brakes can stop or slow mechanical motion.
