This activity introduces the idea of "divide and conquer" using a fictitious but serious problem--a pair of dirty socks has accidentally been wrapped in one of the presents that Santa is about to deli

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what th

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

In this activity about electricity, learners identify parallel and series circuits. First, learners examine and label diagrams of complete circuits.

This activity shows learners how computers use numbers to represent pictures. A grid is used to represent the pixels (short for picture elements) of a computer screen.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

Learners design their own experiment to investigate how pollution diffuses through ground material.

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

In this activity, learners listen to songs and decode hidden messages based on the same principle as a modem. As a final challenge, learners decode the binary messages in a music video.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

Learners design different shaped bandages for different purposes. First, they draw their designs on paper.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

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

In this activity, learners design a therapeutic agent to image and/or cure various diseases in the respiratory system.

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

In this Bob the Builder(TM)-themed activity, learners explore what it means to work together as a team.

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.

Learners will build and experiment with their own windmills made from simple household materials.
