Spherical Reflections
Source Institutions
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.
Stereoscope
Source Institutions
In this activity, learners construct a device that allows them to view 2-D images in 3-D.
Bird in the Cage
Source Institutions
In this activity about afterimages, learners explore what happens when receptor cells called cones in your eye's retina get tired.
Peripheral Vision
Source Institutions
In this optics activity, learners conduct an experiment to explore peripheral vision. Learners collect data about their ability to see shapes, colors, or letters using their peripheral vision.
Disappearing Glass Rods
Source Institutions
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

Source Institutions
In this online activity, learners make a whole rainbow by mixing red, green, and blue light. They can change the wavelength of a monochromatic beam or they can filter white light.
Seeing in the Dark
Source Institutions
In this activity (17th on the page), learners investigate why you cannot see colors in dim light.
Colored Shadows
Source Institutions
In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.
Periscope
Source Institutions
In this optics activity, learners build a spy tool to secretly view things over walls or around corners.
Afterimage
Source Institutions
In this optics activity, learners investigate afterimages.
