In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.

In this activity, learners will be working with a sort of scientific magic, capillary action! They will set up 3 cups of water of different colors, connect them with paper towels and wait.

In this physics activity (page 8 of the PDF), learners will make their very own working compass.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

Learners make bell bracelets, place them on their wrists or ankles, and then dance to the rhythms and sounds the bells make. Many cultures use ankle or wrist bells to make music during dancing.

In this activity, learners will explore the dynamics of air pressure by using a candle, a cup, and a dish of water.

In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.

In this activity, learners investigate the Moon's infancy and model how an ocean of molten rock (magma) helped shape the Moon that we see today.

This is a web activity about simple machines. Learners will explore a lawn mower and identify six different simple machines which work together to help make our lives easier.

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.

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 discover that the human brain is highly adaptable. Learners try to toss beanbags at a target while wearing prism goggles.

In this activity (page 1 of the PDF under SciGirls Activity: Water Slides), learners will whip up some suds with a cup of water and a tablespoon of dish soap until the bubbles are stiff enough to star

This is an online game that explores speed, range and momentum. Learners will pick the winners in a 16-team tournament in 3 events: Tug-o-war, sprint, and marathon.

In this activity, learners discover that the Moon, like Earth, is made up of layers of different materials. Learners work in teams to make models of the interiors of the Moon and Earth.

In this activity learners compare the bounciness of warm and cold racquetballs to see if temperature makes a difference in how well they bounce.

In this activity on page 9 of the PDF, learners make their own paint using chalk as a pigment and glue and water as binders. This activity introduces learners to special mixtures called suspensions.

This fun and simple hands-on astronomy activity lets learners explore what happens when a star explodes.
