In this activity, learners investigate color vision as well as plan and conduct their own experiments.

Learners observe and record what happens when they manipulate bottles containing a liquid (water or corn syrup) and one or more objects (screw, nail, paper clip).

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.

In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

This is an activity exploring color and color mixing.

In this hands-on activity, learners build their own kaleidoscopes and explore how light can reflect of off surfaces such as mirrors, to produce beautiful patterns.

Learners add different liquids (water, salt water, alcohol, and detergent solution) to water and observe the different ways the different liquids combine with water.

In this activity, learners perform an experiment to find out what determines a flower's color.

In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

This is an activity in which learners explore the effects of gravity, motion and momentum while creating art.

In this activity (5th activity on the page), learners explore how what you see influences taste. In experiment 1, learners taste five sodas, one of which is clear soda with orange food coloring.
