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 use simple materials to create giant bubbles.

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

Young learners investigate and observe the properties of three liquids -- water, vegetable oil, and corn syrup. They use their senses to collect data and ask and answer questions.

In this activity about afterimages, learners explore what happens when receptor cells called cones in your eye's retina get tired.

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

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 analyze candy-coated sweets using chromatography. Learners use this method to separate the various dyes used to make colored candy.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

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 (17th on the page), learners investigate why you cannot see colors in dim light.

In this optics activity, learners use a shoebox, colored cellophane and sunlight to "change" the colors of gumballs. Learners will be surprised when the green and blue gumballs appear black!

Learners use chromatography to separate and analyze the mixture of pigments in leaves. Use this activity to discuss photosynthesis as well as why leaves change color in autumn.
