Source Institutions
In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.
Attention!
Source Institutions
In this outdoor art/environmental activity, learners create designs that will attract attention to animals and plants in particular habitats, and then test whether their designs attracted the "right"
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
Plant Hunt
Source Institutions
In this outdoor activity and game, learners collect and sort leaf samples to determine how many types of plants grow in the activity site.
Exploring the Universe: Filtered Light
Source Institutions
"Exploring the Universe: Filtered Light" demonstrates how scientists can use telescopes and other tools to capture and filter different energies of light to study the universe.
Envirolopes
Source Institutions
In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.
See the Light
Source Institutions
In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.
What Causes Rainbows?
Source Institutions
In this activity, learners explore how and why rainbows form by creating rainbows in a variety of ways using simple materials. Learners create rainbows indoors and outdoors.

In this activity, learners explore acid and bases as they create their own invisible ink out of baking soda and grape juice.
See the World Through Color-Filtering Lenses
Source Institutions
In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.
Colored Shadows Investigation
Source Institutions
This activity (located on page 3 of the PDF under GPS: Light and Color Activity) is a full inquiry investigation into mixing colors with light.
Bird in the Cage
Source Institutions
In this activity about afterimages, learners explore what happens when receptor cells called cones in your eye's retina get tired.
Flower Power
Source Institutions
In this activity, learners will experiment with changing flower colors. Learners will investigate the effects of acids and bases on flower colors.
Pie-Pan Convection
Source Institutions
It's difficult to see convection currents in any liquid that's undergoing a temperature change, but in this Exploratorium Science Snack, you can see the currents with the help of food coloring.
Peripheral Vision
Source Institutions
In this optics activity, learners conduct an experiment to explore peripheral vision. Learners collect data about their ability to see shapes, colors, or letters using their peripheral vision.
