Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

Learners take on the role of environmental engineers as they design water filters.

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 math lesson, learners arrange pattern blocks to create tessellations and to explore geometric patterns. Learners first explore making patterns with a variety of pattern blocks.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this activity, learners are invited to imagine the park of their dreams!

In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

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.

In this activity, learners use information gathered from a variety of sources to design and make their own insect.

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

In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

In this design challenge activity, learners build a four-stringed instrument that can play a tune.

After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.

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 will build a neighborhood out of blocks and cardboard.

In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

Have you noticed the plastic rings that are used to hold six-packs of soda? Those rings are great for carrying cans, but they're real trouble when they become trash that animals can get tangled in.

In this design challenge activity, learners investigate series circuits and motors to build a hand-held "kick stick." Their goal is create a battery-operated device that sends a Ping-Pong ball across

In this design challenge activity, learners invent a pinball-like game where a kick stick hits a ping pong ball into a target that buzzes.
