In this activity, learners explore materials through paper chromatography.

In this activity, learners investigate wind by comparing the force of wind in different locations. Learners build wind-o-meters out of wooden sticks and strips of paper.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

In this chemistry activity, learners explore density by using four solids and 6 liquids to create colorful, layered rows.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

If you got a big graduated or clear cylinder, water, a pipe, and a tuning fork, you've got a sound learning opportunity! Learn about resonance with this Exploratorium Science Snack.

In this activity on page 11 of the PDF, learners follow simple steps to recycle old newspaper into new paper.

In this activity, learners design and build a Zoom-a-rang using everyday materials. Experiment with different materials and Zoom-a-rang designs to see how they fly.

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

Is this activity concentrating on physical science, learners build their very own miniature hovercraft out of a paper cup. Using it, they can explore the concepts of friction and force.

In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.

This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.

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

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this online activity, learners make a whole rainbow by mixing red, green, and blue light. They can change the wavelength of a monochromatic beam or they can filter white light.

In this activity, learners explore the real science behind an egg drop "magic trick." Learners will wow their families by harnessing gravity, friction and motion to make 3 eggs fall off of their pedes

In this activity, learners discover how hard their hearts work to pump blood.

In this activity, learners build a toy that flies in circles. This activity introduces learners to center of mass, torque, and rotational motion.

How many colors make black? Gather as many water soluble black markers as you can find.
