This activity attempts to clear up the common misconception that deserts are always hot, totally dry, and uninhabitable.

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 activity, learners are challenged to create a parachute using easily sourced materials in order to transport a LEGO figure safely to the ground.

In this activity, learners make a 3-D model of DNA using paper and toothpicks. While constructing this model, learners will explore the composition and structure of DNA.

In this activity, learners build their your own seismograph with household materials to document shaking.

In this activity, learners will learn how to knit using only their hands. Learners will explore patterns and fabrication as well as develop fine motor skills and patience through this activity.

In this design challenge activity, learners build a device to carry a Ping-Pong ball from the top of a zip line to the bottom in four seconds (or less!).

In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.

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.

In this activity, learners build a seesaw powered by magnets.

This lesson guide includes six simple and quick activities to help learners better understand Bernoulli's Principle.

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

In this hands-on activity, learners will become familiar with the special adaptations of rainforest plants and discover the conditions needed for tropical trees to survive along with what can impinge

In this activity, learners will use a compact disc to build an air puck that can glide across a smooth tabletop. The puck glides with almost no friction on a cushion of air escaping from a balloon.

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

Make a model city happier with LEDs, circuits, motors, and batteries! Groups can think, discuss, design, and build what would make a community happy. Kids can work as part of a team or on their own.

In this outdoor activity, learners discover that plants aren't just shoots (stem, branches, leaves, and flowers) growing above ground, but contain plenty of roots growing underground—more than half th

In this activity (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.

In this experiment, learners will explore whether increased carbon dioxide makes our oceans more basic or more acidic.

In this activity, learners will engineer three different parachutes to test how well each one works.
