In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

Are fingers the only place on the body where we use our sense of touch? In this activity (6th activity on the page), learners test the touch sensitivity of different parts of the body.

In this activity, learners will create a model rocket out of an inflated balloon attached to a straw on a taught string.

In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.

In this activity, learners construct hail-proof houses using recycled materials to discuss storm readiness and safety.

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

Students design and build their own parachutes in this hands-on engineering project.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

Coins are everyday objects which tell a lot about the people who use them.

In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

In this activity, learners design a bungee jump for an egg using nylon stockings.

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

In this engineering activity, challenge learners to build a tower out of 10 sheets of newspaper and 3 feet of masking tape, which can hold a golf ball balancing at the top.

In this activity, learners explore the flexibility of polymer chains by pushing sharpened pencils through a Ziploc bag.

In this activity, learners will explore how and why weight distribution works.
