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

In this activity, learners explore the concept of rotational equilibrium. Learners work in teams to estimate and determine the force within a mobile design.

In this activity, learners draw natural objects to explore the details, differences, and similarities of natural objects.

In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

In this three-part math activity, learners explore shapes. In part one, learners identify, describe, and classify two-dimensional shapes.

In this indoor and outdoor activity, learners discover that insects grow and develop as do all living things, going through a process known as complete metamorphosis.

In this activity, learners explore the concepts of density and basic chemical reactions as they create a homemade lava lamp effect using water, oil, food coloring, and Alka-Seltzer tablets.

In this activity, learners will use bubble wrap to print patterns on paper and experiment with mixing colors.

In this activity, learners construct drawing machines using a cup, some markers, and a battery pack. The markers act as "legs" for the machine, making a drawing that records as it moves.

In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In this math lesson, learners participate in a variety of activities that give them experience in recognizing, describing, and extending repeating and arithmetic patterns.

In this activity, early learners create paintings by making music and rhythm. Learners place paper in cans, add paint-soaked beans (or pebbles) and put the tops on.

In this simple chemistry activity (page 1 of PDF under SciGirls Activity: Colorblind Dogs) about acids and bases, learners will mix a baking soda and water solution and use it to paint a message on a

In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

This activity is about the mural making process done about 9,000 years ago in Catalhoyuk, Turkey.

In this activity, learners will swirl paint into shaving cream to make an extravagant nebula print.

In this activity, learners use beads, which represent amino acids, to create protein bracelets. Learners examine the relationship between amino acids and proteins.

In this activity, learners will dip different items in paint and then roll those items down a ramp. Learners will use science process skills such as observations and experimenting.
