AP4785 - $7.80
This set of five transparent acrylic squares will be a valuable resource during your discussions of color theory. The rigid acrylic color filters can also be used as a wavelength filter set with bright light projection demonstrations or with student...
AP4786 - $8.35
This color filter set is ideal for work that requires “flexibility.” The cellophane-type material can be curved around test tubes or other objects for filtering effects. These handy-sized filters are perfect for producing defined colors...
AP6868 - $19.20
Mind-boggling! Display the colors of the rainbow by rotating a black-and-white disk! Spin the disk in the opposite direction and the color order reverses. How is this possible? It is the result of the brain's perception of flashing white light. A fun...
AP6172 - $43.75
Shed light on the concept of color perception with this overhead projector demonstration. Why are some objects blue and others red? Does a color filter actually change white light into colored light? What color is seen when blue and yellow light are...
AP6423 - $3.80
Excellent color filters, at an affordable price! It's easy to illustrate color mixing by subtraction. Simply overlap two colored paddles and place them on an overhead projector. A brilliant display of complementary colors will appear-yellow and blue...
AP6162 - $11.10
What is color? Why do we see different colors? Demonstrate and explain to students why objects look the color they do using these three highly visible color wheels and a centrifuge device! A two-colored wheel is placed on the centrifuge device and...
AP6712 - $33.40
How does a rainbow of colors turn white? Clearly demonstrate that white light is composed of all the colors of the rainbow. This 23-cm diameter sturdy plastic color wheel comes with a plastic handle that attaches to the center of the wheel. Start the...
AP6843 - $15.30
Challenge your students' sense of sight by saturating their cone cells! After focusing on an “oddly-colored” image for one minute; students will be amazed at what they “see” when they look down at a sheet of white paper. The colors magically change...
AP7148 - $29.95
An easy-to-follow chart that simplifies the electromagnetic spectrum! Displays the wavelengths of familiar electromagnetic waves such as FM radio, cellular phones and X-rays, and colorfully shows the relatively small bandwidth of visible light. Frequency...
AP7262 - $22.10
Finally an easy way to combine the primary colors of light! Many people have seen white light dispersed into a spectrum after it has passed through a prism, but few have observed different colors of light combined to make white light. In this teacher-led...
AP7230 - $15.00
Our most popular scientific charts are now available in notebook size! 8½" x 11", color, notebook size, pad of 30. An easy-to-follow chart that simplifies the electromagnetic spectrum! Displays the wavelengths of familiar electromagnetic...
AP7284 - $32.05
There is more to light than meets the eye! Instead of just giving your students information about the electromagnetic spectrum, allow them to discover infrared and ultraviolet light for themselves. Two “enlightening” demonstrations reveal evidence...
AP7161 - $32.30
Show students a spectroscope, and they can see the spectrum of colors from visible light. Let them build a spectroscope, however, and suddenly students discover not only why white light is separated, but also why different light sources produce different...
AP7398 - $26.75
Help students clearly see the difference between primary colors of light and primary colors of pigment. Show color mixing by addition using blue, red, and green filters. The three primary colors of light are projected onto a screen then refracted to...
