In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

In this activity, learners explore density and buoyancy as they design and construct rafts.

In this quick activity about size and scale (on page 2 of the PDF under What's Nano?

In this activity, learners mimic remote sensing. Learners use a stick to measure the distance to a "planet surface" they cannot see, and create their own map of the landscape.

In this physical activity, two lines of learners link hands and arms to model a beam subject to various loading schemes.

In this activity related to computer programming, learners give directions to a "robot" (either an adult or another learner) and find out which instructions the robot is able to follow, and how their

In this activity (on page 4), learners create a submarine using a plastic sandwich bag. This is a fun way to learn about buoyancy and how captured gas can cause objects to float.

In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

With two stacks of books and a few rolls of pennies, build two kinds of bridges--a beam span and an arch span--and see how much weight each of them can hold.

In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.

In "Exploring the Solar System: Mars Rovers," participants learn about how scientists and engineers use robotic rovers and other vehicles to explore distant worlds, and experience some of the challeng

This is an activity about rockets. Learners will explore how rockets leave Earth's orbit and what it takes to make a launch successful.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

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.

Learners observe and discuss a simple model of a wet scrubber, a device for cleaning industrial air pollution.

In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.

Learners initially test to see how many drops of liquid (water, rubbing alcohol, and vegetable oil) can fit on a penny.

In this activity on page 9 of the PDF, learners test how flavoring extracts move through the walls of a balloon.
