In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.

This is an activity (located on page 3 of PDF under Hockey Sticks Activity) about composites, materials made of 2 or more different components.

Computers store drawings, photographs, and other pictures using only numbers. Through this activity, learners decode numbers to create pictures using the same process that computers use.

In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.

In this activity, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building.

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

In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.

In this activity, learners explore the structural strength of triangles by creating their own free-standing geodesic dome out of plastic straws.

In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.

In this activity, learners play a game similar to Hangman by guessing a secret phrase to understand how computer scientists measure the amount of "information" in a document.

This hands-on activity shows you how to build basic architectural shapes out of toothpicks and gumdrops.

In this activity, learners build bridges out of newspaper and tape to explore how structures are designed to bear loads.

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.

In this activity, learners design, build, test and redesign a display tower that will meet a specific set of criteria and constraints.
