Lab 2

Learning Objectives

Use a step by step problem solving process to deduce the rules for color addition.

Learn how to use three apparati to manipulate and measure color perception.

Graphically depict the results.

Materials Needed

1. Microcomputer connected to network (Part C)
2. Hand Stand Perimeter, Instructions, Color samples, wand, colored marking pens (Part A)
3. Color Wheel and color disks (Part B)
4. Singerman Color Mixer (Part C)

5. PowerPoint Software (Part C)
6. APA Publication Manual

Instructions

Part A. Color Perception: With a partner map the retina of your right eye for sensitivity to the colors of red, blue, green, yellow and white. Show your results by marking the color sensitivity areas on the chart provided in lab. Work on this activity alternately with the other activities in order to avoid eye strain. Find the "blind spot" for each individual.

Part B. Color Addition- Color Wheel.
With the color wheel determine the rules of color addition by adding together the colors blue, red, green and yellow (two at a time). Note that the Color Wheel works best in direct sunlight. Record your results on your lab report.

Part C. Color Addition- Singerman Apparatus. With the Singerman Apparatus deduce the rules of color addition by adding colors three at a time. The center portion where all three colors overlap should be white (possible seen as light gray). Note that the color mixer works best in a dark room. It will be set up in a room near the lab.Use the diagrams on your lab report to record your data. Use PowerPoint on the microcomputers to produce a chart of the results for the correct solution.

Write a report of your results and file it on the R drive. (See standard lab report form in the R:Drive.) Be sure to cite one source in your report and reference it in correct APA style format.
