In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

In this activity, learners will create their own museum collection using their favorite toys, drawings, or collection.

In this activity, learners explore why they can see colors in bubbles and why they change.

In this physics activity, challenge learners to make and race a balloon-powered car. Learners construct the body out of a paper cup, wheels out of wooden spools. and fuel tank out of a balloon.

In this activity, challenge learners to make a pencil stand on its tip using only two pieces of wire and two clothespins. Use this activity to demonstrate the center of gravity.

In this activity related to the famous "Stroop Effect," learners explore how words influence what we see and how the brain handles "mixed messages." Learners read colored words and are asked to say th

In this activity (1st on the page), learners find their blind spot--the area on the retina without receptors that respond to light.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.

In this activity, learners calculate the width (horizontal diameter) of the blind spot on their retina. Learners make a blind spot tester using a piece of notebook paper.

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 data analysis activity, learners quantify the abundance and distribution of sea scallops in and adjacent to the Mid-Atlantic closed areas.

On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes.

In this activity, learners investigate whether more people are squares or rectangles. People with similarly sized heights and arm spans are classified as squares.

In this outdoor activity, learners discover the wonders of the habitat surrounding them.

In this engineering activity, challenge learners to invent a water filter that cleans dirty water.

In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil.

In this optics activity, learners create a ripple tank from household materials to study waves. Learners build the tank and then explore by making various types of waves.

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.
