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, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

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.

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 perform 20 arm curls with cans that simulate the weight of beans on Earth versus the weights of the same number of beans on the Moon and in space.

In this space science activity, learners work together to create a human-powered orrery to model the movements of the four inner planets.

In this activity, learners drop impactors onto layers of graham crackers!

In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.

In this activity, learners use a simple 3D model to discover why the Moon has phases.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

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.

During this activity, learners will make different versions of "ooze" using varied proportions of detergent and glue.

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

In this quick activity (located on page 2 of the PDF under GPS Wetlands Activity), learners will model how wetlands act as natural filters for the environment.

In this quick activity (page 2 of PDF), learners will play a game using their observation and listening skills, interpreting clues from each other to deduce their secret animal identity.

In this activity, learners work in groups of four to explore light. Learners create new colors from the primary colors of light from flashlights covered in theatrical gels or cellophane.
