In this matching game, learners study the limits of life on Earth to see what other places in the solar system might sustain microbial life.

During this lesson, learners will determine their blood pressure and learn about systolic and diastolic pressures.

In this activity about neuron/target muscle recognition (page 44 of the PDF), learners arranged in two rows facing away from each other use string to simulate neural development.

Directed by instructional cards, learners kinesthetically model cell communication by acting as components in a cell signaling pathway.

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.

In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.

In this physics activity, learners build a toy with a figure that spins around like a gymnast on the high bar.

In this activity about human interface design issues, learners help the Oompa-Loompas of a great chocolate factory solve different 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.

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.
