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 explore what happens when polarized white light passes through a sugar solution.

In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.

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.

Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.

In this activity, learners use a laser pointer and two small rotating mirrors to create a variety of fascinating patterns, which can be easily and dramatically projected on a wall or screen.

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.

Learners demonstrate how water can distort, refract and magnify light.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

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.

In this activity about light and perception, learners create pictures in thin air.

In this fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.

In this activity, learners explore the invisible infrared radiation from an electric heater.

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 (described on pages 39-42 of PDF), learners make a paper wheel (on pages 57-60 of PDF) that shows them the relative loudness of different sounds.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

In this activity (on pages 25-32 of PDF), learners make models of the inner ear out of pipe cleaners.
