In this activity, learners create 3D geometric shapes using straws and pipe cleaners.

In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.

In this activity, learners will determine if the frequency and intensity of hurricanes are changing using real data from the National Hurricane Center.

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.

This is written as a static display, but can easily become a hands-on experiment for learners.

In this activity, learners will use a variety of household and/or natural objects to design a sculpture that balances from a single point.

This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

In this activity, learners construct a cereal chain as a model of how proteins are made in the cell.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this twist on a classic design challenge, learners will try to stop a bouncy ball from bouncing as they explore how to control the fall of an object.

In this activity, learners play a card game that explores the relative sizes of various objects. Learners compete to organize their hand of cards into lists of objects from largest to smallest.

This laboratory exercise is designed to show learners how DNA can easily be extracted from wheat germ using simple materials.

An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.

In this activity, learners explore how genetic switches function and the role of genetic switches in the process of evolution.

In this data activity, learners will explore shipwrecks from four National Marine Sanctuaries on the West Coast of the United States.

In this activity, learners are challenged to build a bird feeder using recycled materials from home and are encouraged to problem solve during the extensions.

In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

In this activity, learners recreate a method of detecting and correcting errors in computers called 'parity'.
