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

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.

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

This is an educator-led demonstration of microarray technology using a model created from a pizza box and ping-pong balls.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

In this activity, learners build a switch to turn electrical circuits on and off.

In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.

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

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

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.
