Seeing 3D
Source Institutions
Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!
Mirrors and Images
Source Institutions
In this optics activity, learners explore how many objects they can see in a set of mirrors (hinged like a book) at various angles.
CD Spectroscope
Source Institutions
In this activity, learners use an old CD to construct a spectroscope, a device that separates light into its component colors.
The Straw Flute
Source Institutions
In this is activity about sound and vibration, learners create their own 'flutes' with drinking straws, then investigate how changing the length of the straw affects the sounds that are produced.
Pinhole Viewer
Source Institutions
In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.
Earth's Energy Cycle: Albedo
Source Institutions
In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.
Blind Spot
Source Institutions
In this activity, learners conduct a simple test to find their blind spot.
Screaming Balloon
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: Extreme Sounds) about sound vibrations, learners will investigate which small objects, such as coins, hex nuts, or marbles, produce t
Shadow Dance
Source Institutions
In this activity, learners experiment with shadows and light sources to understand the relationship between the angle illumination and the shadow's length.
Straw Kazoo
Source Institutions
In this activity, learners make some music by constructing a kazoo out of a simple plastic drinking straw. Use this activity to explore sound, vibrations, and music.
Exploring the Universe: Pack a Space Telescope
Source Institutions
Space telescopes can offer us better, clearer views of the universe (and of our own planet) than Earth-based telescopes can, but getting these large, delicate pieces of equipment into orbit is tricky.
Exploring the Universe: Exoplanet Transits
Source Institutions
In "Exploring the Universe: Exoplanet Transits," participants simulate one of the methods scientists use to discover planets orbiting distant stars.
Soap-Film Painting
Source Institutions
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.
The Three Little Pigments: Science activity that demonstrates the primary and secondary colors of lightScience activity that demonstrates the primary and secondary colors of light The Three Little Pigments Know your C, M, Y, and K.
Source Institutions
Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.
What's the Buzz
Source Institutions
In this physics activity, learners explore how sound is created by vibrations.
Magic Wand
Source Institutions
In this activity about light and perception, learners create pictures in thin air.
The Ripple Tank
Source Institutions
In this optics activity, learners create a ripple tank from household materials to study waves. Learners build the tank and then explore by making various types of waves.
Hole in Your Hand
Source Institutions
Create an illusion where it appears that your hand has a hole in it. You'll see the results from when one eye gets conflicting information.
Mix and Match
Source Institutions
In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.
Far-Out Corners
Source Institutions
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.
