In this activity, learners will use Google Sky to observe features of the night sky and share their observations.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

In this activity, learners explore ray optics. Learners discover that they can use a magnifying glass to create an upside-down image.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this activity, learners experiment with their voices and noisemakers to understand the connections between vibrations and the sounds created by those vibrations.

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

In this activity, learners will explore how water affects marker on filter paper. Learners will use science process skills such as making observations and predictions as they explore color.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

This is an activity exploring color and color mixing.

Everybody loves bubbles, and this is the best bubble recipe ever!

In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

This is a series of three quick science activities to do with a spoon, knife, and fork. In the first two activities, learners use the flatware to explore optics, mirrors, reflection, and distortion.

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

In this easy demonstration (3rd on the page), learners explore depth perception by conducting a test with two pencils.

In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.
