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

In this activity, learners explore how engineers work in a team to solve problems.

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

In this activity learners will build roller coasters and test them using small balls or marbles.

In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

In this 6-7 day investigation, learners begin with an introduction to seamounts that are present in the Gulf of Alaska.

In this activity, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.

In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.

In this activity, learners build their own sound machines and explore the interplay of motion and sound.

In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment.

In this activity (pages 13-14), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

Hooray! In this design challenge activity, learners invent a device that launches a spoonful of confetti into the air. Learners are encouraged to create the biggest cloud of confetti possible.

This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.

Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

In this activity, learners explore electronics and motion by making a Scribbling Machine, a motorized contraption that moves in unusual ways and leaves a mark to trace its path.

In this activity, learners use their strength to light a light bulb. A chain made from paper clips is placed in series with a battery and flashlight bulb.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.
