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.

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

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 water activity, learners discover ways to move water across the water table.

In this activity, learners use pop-beads to understand the characteristics and properties of polymer chains.

In this activity (pages 3-4), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

In this design challenge activity, learners design and build a circuit: an "electric highway" that connects a battery and buzzer at least three feet apart using four types of materials.

In this activity (pages 7-16), learners model various crystal structures with LEGOs. This activity also contains additional links that explain how to create other crystal structures.

In this activity, learners build a tiny but powerful flashlight out of simple materials. Use this activity to introduce learners to electrical circuits and conductivity.

In this activity, learners will create a speaker using a paper cup, magnet, and enameled wire. Also included in this activity is a Mr.

This activity was designed for blind learners, but all types of learners can explore the process of extrusion used to produce pipes and wires in industry.

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

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

In this activity, learners construct a rocket powered by the pressure generated from an effervescing antacid tablet reacting with water, and build a launch pad for their rocket.

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