Why Are Bubbles So Colorful?
Source Institutions
In this activity, learners explore why they can see colors in bubbles and why they change.

Colors, Colors?
Source Institutions
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

Our Sense of Hearing
Source Institutions
In this activity, learners investigate the sense of hearing and plan and conduct their own experiments.

Ants
Source Institutions
In this outdoor activity, learners investigate ant behavior by testing ant feeding reactions to different types of food.

Critical Angle
Source Institutions
In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

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

Bone Identification
Source Institutions
This activity (page 3 of the PDF under SciGirls Activity: Dinosaurs) is a full inquiry investigation into fossil hunting and identification.

Does Sunscreen Protect My DNA?
Source Institutions
In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

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

See It to Believe It: Visual Discrimination
Source Institutions
In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.

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

Finding a Gene on the Chromosome Map
Source Institutions
In this activity, learners use pedigree and jigsaw puzzles to explore how scientists use genetic information from a family to identify a gene associated with a genetic disorder.

Measuring Your Blind Spot
Source Institutions
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.

Beam Me Up!
Source Institutions
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.

Expose Your Nose
Source Institutions
In this simple exploratory activity (1st activity on the page), blindfolded learners try to identify mystery items by smell.

The Scoop on Scallops
Source Institutions
In this data analysis activity, learners quantify the abundance and distribution of sea scallops in and adjacent to the Mid-Atlantic closed areas.

Our Chemical Senses: Olfaction
Source Institutions
In this activity, learners investigate the olfactory system by conducting several experiments.

Are you a Square or a Rectangle?
Source Institutions
In this activity, learners investigate whether more people are squares or rectangles. People with similarly sized heights and arm spans are classified as squares.

Habitat Observations
Source Institutions
In this outdoor activity, learners discover the wonders of the habitat surrounding them.
The Ripple Tank
Source Institutions
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.
