Many thanks to my daughter, Hannah Hospitál, for this excellent idea.
As a science teacher at a school for the blind, I have often been asked how colors can be effectively described to students with visual impairment. We often use descriptive words with colors such as "fiery red" or " deep purple". These descriptions mean very little to students who have not experienced colors. A more concrete science-based explanation of why there are various colors is the basis of this activity. It will be most appropriate for students who already understand the structure of a wave or in conjunction with instruction on waves. This hands-on activity provides students with a more concrete understanding of how color varies based on difference in wavelength.
Science concepts related to waves and wave structure may need to be reviewed in order for students to fully comprehend this activity.
