Investigate a flower's power of marketing by making an imitation flower that successfully signals a bee (or other pollinator of your choice) to visit.

In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.

In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

This is an activity where learners will compare the different metamorphosis stages of amphibians.

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.

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

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

In this activity about electricity and magnetism, learners examine what happens when a magnet exerts a force on a current-carrying wire.

In this activity, learners use their sense of smell to explore the world on the nanoscale.

In this activity, learners make their own flip book that shows real solar flares erupting from the Sun in November 2000. Step-by-step instructions are included with photos.

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.

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

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

“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.

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.

This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.

In this activity, learners examine raindrop bottles (prepared ahead of time) to observe in slow motion the behavior of falling droplets and explore concepts such as drag and terminal velocity.

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