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

This activity helps students learn how computers "compress" text by identifying repeating patterns of letters, words, and phrases.

This magic trick is based on how computers detect and correct data errors.

In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.

In this activity, learners create virus models, including nucleic acid and proteins, using simple materials. This resource includes information about virus structure and gene therapy.

In this activity, learners explore how the shapes, sizes, and distances of land masses appear differently on two different models of Earth: an icosahedron and a flat map.

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!

In this activity about encryption, learners cut out a secret decoder badge from a handout and use it to encode messages to each other.

In this activity, learners construct three quick and simple mechanisms to start building a pop-up book. Learners fold, cut, and glue paper to make a bird beak, parallelogram, and V-fold.

No glue is needed for learners of any age to become marshmallow architects or engineers.

In this engineering activity, young learners investigate multi-level buildings.

Learners conduct four simple experiments to demonstrate the effects of air pressure.

In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

This activity lets learners participate in the process of reconstructing a phylogenetic tree and introduces them to several core bioinformatics concepts, particularly in relation to evolution.

In this activity, learners build a paper model of the spacecraft and photometer (telescope) used during NASA's Kepler Mission.

With little more than a plastic bottle, some vinyl tubing, and a length of PVC pipe, make a rocket and a rocket launcher and investigate how rockets fly.

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

Build a pinwheel that works without wind! This activity contains steps on how to build a parachuting pinwheel out of paper, a film canister, and some brads.

Experiment with force and pressure by building a balloon rocket. When launched, the balloon will run a track wherever you place the string.
