Kaleidoscoptical Activity—Demonstration Kit

By: Bob Becker, Kirkwood H.S., Kirkwood, MO

Item #: AP8781

Price: $56.15

In Stock.

The Kaleidoscoptical Activity Chemical Demonstration Kit demonstrates key concepts of the visible light spectrum and optical activity. Students use two pieces of polarized filter material and corn syrup to reveal a rotating array of colors.

Product Details

A radially polarized filter is placed on an overhead projector and a parallel polarized filter is positioned above it. The image produced shows four quadrants, alternating light-dark-light-dark. As an optically active solution is poured between them in a beaker, the image rotates and separates into a beautiful array of spectrum colors.

Concepts: Visible light spectrum, optical activity.
Time Required: 15 minutes 
Note: A 600-mL tall-form beaker, corn syrup and an overhead projector are needed.

Performance Expectations

MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
HS-PS4-3. Evaluate the claims, evidence, and reasoning behind the idea that electromagnetic radiation can be described either by a wave model or a particle model, and that for some situations one model is more useful than the other.
