In this activity, learners build a game that tests their steadiness. Learners construct the game board by setting up an electrical circuit and a wand.

In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

This activity was designed for blind learners, but all types of learners can use it to build and examine a basic electrical circuit.

In this activity, learners explore the economics of coal mining as you they use fake money to purchase mining tools, attempt to carefully mine their cookies, sell their chocolate chip ore, and try to

Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

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

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

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

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 this activity, learners make water-walking critters using thin wire, and then test how many paper clips these critters can carry without sinking.

In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

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

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.
