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

In this design challenge activity, learners use a balloon and other simple materials to design an air-powered rocket that can hit a distant target.

In this activity (page 1 of PDF under SciGirls Activity: Pet Handedness), learners will construct a simple spinning top out of a circle of construction paper, a film canister lid, and a bamboo skewer.

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 design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp

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

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 explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity learners will build structures out of blocks and then roll balls to try to knock them down.

In this lab (Activity #1 on page), learners explore how we see color.

In this activity, learners explore the concept of how engineering solved the problem of human/computer interface.

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 investigate balance and symmetry by designing a symmetrical butterfly, using a paper cutout.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.

In this activity, learners explore how boats are engineered to achieve speed.

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

In this design challenge activity, learners use tubes of newspaper to make a table that’s at least eight inches tall and strong enough to hold a heavy book!
