Even fast computers are limited to how quickly they can solve problems. One way to speed things up is to use several computers at once.

This simple activity uses paper and scissors to convey two key concepts to learners: the nanoscale is very small and working on the nanoscale requires special tools.

This activity (on page 3 of the PDF under GPS: Roller Coaster Design Activity) is a full inquiry investigation into g-force and acceleration.

In this activity, groups of four learners must complete a set of four manual tasks. The restrictions are that they must complete the tasks in a limited time while wearing garden or rubber gloves.

Build a musical ice theremin by programming a micro controller, like a Pico Cricket to respond to resistance generated by the ice melting, or the ice being touched.

Learners participate in a variety of activities modeling different disabilities.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity, learners use three types of cheesy snacks--cheese balls, cheese puffs, and Cheetos--to learn about polymers.

In this activity, learners explore accuracy and precision.

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

In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.

In this activity, learners examine antibodies and antibody recognition using a model.

What's a more compelling problem to solve than being stranded on a deserted island?

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

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 activity, learners explore how engineers develop pipeline systems to transport oil, water, gas, and other materials over very long distances.

In this activity, learners explore the history of making objects from glass and artistry of Dale Chihuly.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.
