Learning Exercise
Cookies and Color
Students will practice mixing colors using food coloring and frosting. Aimed for use of discussion of wavelengths and how they determine what colors we see. Also for use in discussing primary and secondary colors.

Wavelengths and Color: Lesson Plan
Maria Alejandra Lucero
Objective & Description:
Students will understand that white light is a mixture of the different colors of the spectrum and the colors we see are variations of that concept. The following activity is supplemental, building on the concepts of color and its relation to wavelength. The activity is designed for level 2 through 4 ELD students.
Standard Addressed:
6.e. Students know that white light is a mixture of many wavelengths (colors) and that retinal cells react differently to different wavelengths.
Prerequisites:
Students must have an understanding of white light, wavelength, and colors.
Time Required: 45 minutes
Materials:
Sugar cookies, white frosting, food coloring, paper napkins, index cards, small paper cups, plastic utensils
Preparation:
For each pair of students, prepare an index card with a recipe of how many drops of what color each student should mix into their frosting. Scoop small amount of frosting into small cups and place one at each seat with utensils, napkins, and food coloring bottles.
Procedure:
Time (min)
(10) Review previous notes and lectures, covering the composition of white light, colors, and reflection and absorption.
(5) Pass out cookies and go over instructions on worksheet.
(15) Allow students to work independently.
(5) Clean up materials and throw away dirty utensils and napkins.
(10) Go over results with class. Discuss following topics:
i. Do the colors you make fit on the spectrum, or are they in between colors?
ii. What colors did you use to make those colors?
iii. How do you think this relates to how we see other colors, like brown?
Accommodations:
Students requiring additional accommodations for the completion of the lesson are given written copies of the instructions in addition to oral instructions. Then instructions should be repeated before the start of the lesson and reinforced on an individual basis by the teacher.
