Coloration - Teacher's Guide

   Episode Overview
skunkJunior Naturalist Patrice explains how coloration is a structural adaptation that helps animals and plants survive in their environment. She joins Senior Naturalist Dave Erler to examine the coloration of the great horned owl. We take an up-close look at the skunk. Von and Marrissa visit with wildlife photographer John Green and learn how color plays a role in photography.
   Program Objectives

Students will:
1. Analyze how structural adaptations help organisms survive.

2. Identify coloration as a structural adaptation.

3. Give examples of coloration in living organisms.

4. List and describe different types of coloration. i.e. deceptive, mimicry, camouflage, advertising, countershading.

5. Recognize the distinct characteristics of the  great horned owl and the striped skunk.

6. Describe adaptations exhibited by the  great horned owl and the striped skunk.

   Previewing Activities

1. Have students name some animals and plants with unusual coloration and discuss how that coloration might help the them survive.

2. Have students name some ways color is used in human environments for warning, attracting and to camouflage or mimic.

   Post-Viewing Activities

1. Have students make a list of animals that use:
Counter Shading
Advertising Coloration
Camouflage
Mimicry

Then have them choose one of those animals and research it further.

2. Give students an outline of a butterfly. Explain that the classroom is the butterfly's habitat. Have them design an unique coloration pattern for their butterfly and write a brief paragraph explaining how the coloration of their butterfly helps it survive in the classroom environment.

3. Take a nature walk with your students and have them observe plants and animals and take notes about their coloration.

   Trials of the Toothpick  Bird

 Materials Needed

colored toothpicks
grassy area
recording sheets

Process

Tell the students that they are testing which color tooth-pick would survive the best in a grassy environment. The students are to play the part of the rare toothpick bird.

Mark off a grassy area. Distribute an equal of each color toothpicks on the grass. Give the students 15 seconds to find as many of the toothpicks as they can. Record the number of toothpicks "eaten" for each color. Which color was the most vulnerable to the toothpick bird? Which one was the best protected?

Note: You can do this activity as a whole class, or you can break the class into small groups.

But We Can't Go Outside!
If you can't go outside to do this activity, or if you don't have a grassy area, you can replicate the activity by distributing a sheets of newspaper to each student and sprinkling colored confetti and cut-up newspaper. Make sure there is an equal number of each!
