Balance a ball in the air with a hair dryer! This Exploratorium produced activity shows learners concepts like lift and air streams. You can try many different angles, speeds, and ball types.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

In this activity, learners explore gravity and air pressure as they experiment with holding a glass full of water upside down, without spilling it, using a simple piece of cardstock.

Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.

Which one of your eyes are dominant? Do they act independently or are they equally "in control?" This activity explores how your eyes work (or don't work) together.

In this activity about depth perception, learners create an optical illusion in a shoe box.

In this activity, learners will explore acid-base reactions and create their own bubbly results.

In this optics activity, learners discover how they can make glass objects "disappear." Learners submerge glass objects like stirring rods into a beaker of Wesson™ oil to explore how the principles of

This lesson familiarizes learners with the term "tropical belt." First, learners locate the equator, Tropic of Cancer and Tropic of Capricorn on a map and trace these lines with a crayon.

In this activity, learners discover a brain process called habituation.

In this game, learners cutout a model black hole "cone" and attempt to roll around a marble or other small spherical object without touching the event horizon.

Discover how sound travels and what materials make better sound conductors. Can you hear better with your fingers in your ears? Find out with a coat hanger and some string!

“Exploring the Solar System: Big Sun, Small Moon” is a hands-on activity that explores the concept of apparent size and allows visitors to experience this phenomena using familiar objects—a tennis bal

In "Chemistry is Colorful" learners explore different materials through paper chromatography.

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

In this activity about transfer of energy, learners get to build their own catapult using nothing more than a plastic spoon and some tape.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

In this activity, learners make a model of the solid Earth's layers that's good enough to eat! Learners use tasty foodstuffs to simulate Earth's inner core, outer core, mantle, and crust.

In this activity, learners design a bungee jump for an egg using nylon stockings.
