In this activity, learners discover that it's difficult to distinguish between two different shades of gray when they aren't separated by a boundary.

Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.

“Exploring the Universe: Orbiting Objects” is a hands-on activity that invites visitors to experiment with different sized and weighted balls on a stretchy fabric gravity well.

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

In this neuroscience activity (5th activity on the page), learners explore their sense of touch without using their senses of vision and hearing.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

Molecular gastronomy is the scientific study of food preparation. Learners use self-assembly techniques to create edible capsules of chocolate syrup (food grade ingredients are required).

In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.

Wheels aren't the only things that can "roll" objects that are placed on top of it. Make non-intuitive shapes from cutouts and a compass to demonstrate this.

Make a big canvas of iridescent color with pvc pipe! In this Exploratorium Science Snack, you'll need to cut and assemble some PVC pipe, but the pay-off, the soap-bubble canvas, is big.

Learners make a simple battery out of "sandwiches" of aluminum foil, pennies, and a salt water-soaked paper towel.

In this simple exploratory activity (1st activity on the page), blindfolded learners try to identify mystery items by smell.

Are there boxes, is this an illusion, or is this real life Q-bert? Illusions are always fun to build especially when you can build them.

Learners use two mirrors to explore how images of images of images can repeat forever.

In this activity (4th activity on the page), learners use their sense of smell to rate and arrange containers filled with different dilutions of a scent (like cologne or fruit juice) in order from wea

This Exploratorium activity explores size and scale. Through four levels of screen sizes, learners can sort out objects of different sizes.

In this optics activity, learners explore interference by adding wax blocks to a ripple tank.
