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.

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.

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.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

In this math activity, learners make their own bubble wands and determine if the size of the wand affects the number of bubbles it produces.

In this activity, learners use oil, water, food coloring and antacid tablets to create a bubbling lava lamp. Use this activity to introduce concepts related to density, hydrophobicity vs.

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

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.

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

Learners shine the light of a laser pointer through sheets of fabric that all have a different number of threads per inch.

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 practice matching and subitizing as they create the longest domino train possible.
