Instructions
With your team determine the rules of color addition by using
a step by step problem solving process. Be sure to keep track of
each step because you will have to summarize them in your lab report.
(Hint: You should consider using the five steps presented in lecture,
starting with "Identify the Problem.") Some of the "Facts" for
this lab are in the internet sources.
Using the E-Prime color wheel simulator and the physical color wheel
determine the rules of color addition by adding together the colors two
at a time. Note that the physical color wheel works best in direct
sunlight.
After you have determine a preliminary solution using both the physical
color wheel and the virtual color wheel check with your
instructor. Then you will be approved to verify your solution
with the Singerman Apparatus. There is only one working Singerman so
you will need to share with the other teams, but only one team at a
time should use it to check their solution. With
the Singerman Apparatus you may add 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 a graphics program to produce a visual representation of the
results for the correct solution that you can add to your team wiki.
Write a report of your results as your team wiki report
for this week. Be sure to cite one source in your report
and reference it in correct APA style format.
