Touch the Spring (Lightbulb)
Source Institutions
In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.
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.
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.
Cylindrical Mirror
Source Institutions
In this activity, learners create a cylindrical mirror to see themselves as others see them.
Water Sphere Lens
Source Institutions
In this activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.
Polarized Light
Source Institutions
In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.
Hot Spot
Source Institutions
In this activity, learners explore the invisible infrared radiation from an electric heater.
Mirror, Mirror on the Wall: Angles of Reflection
Source Institutions
In this optics activity, learners work in pairs to explore how mirrors work. Learners use tape to mark the angles needed to see each other's reflection in a wall mirror.
Critical Angle
Source Institutions
In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.
Stereoscope
Source Institutions
In this activity, learners construct a device that allows them to view 2-D images in 3-D.
Kaleidoscope
Source Institutions
In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).
See the Light
Source Institutions
In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.
See the World Through Color-Filtering Lenses
Source Institutions
In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.
Corner Reflector
Source Institutions
In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.
Camera Projector
Source Institutions
In this activity (posted on March 14, 2011), learners follow the steps to construct a camera projector to explore lenses and refraction.
Mirrorly a Window
Source Institutions
In this activity about light and reflection, learners discover that what you see is often affected by what you expect to see.
Periscope
Source Institutions
In this activity, learners construct a device that allows them to look over ledges or around corners.
Mirror, Mirror
Source Institutions
In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.
Kaleid-o-mania
Source Institutions
In this hands-on activity, learners build their own kaleidoscopes and explore how light can reflect of off surfaces such as mirrors, to produce beautiful patterns.
Fish Eyes: More than Meets the Eye
Source Institutions
In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.
