Chapter 14.2 Color CPO Science Integrated Physics & Chemistry

Developing A Model  What is Light?  Why are there different colors of light?  These are the wavelengths & frequencies of each color of light

Key Questions  What is light & why are there different colors?  How do different colors of light interact?  How do we create colors for clothes, TV’s, printer’s etc…?  How does the human eye work?

Developing An Experiment  How can we create the three colors we are going to examine? —Color filters  What are we going to test? —Different mixtures of the colors

Run The Experiment Tips : —The lights will not make perfect circles & it may be necessary to move one light closer or further from the paper —The colors will not be perfect.

What Did You Learn?  What colors did the mixtures make? —Red + Green = Yellow —Green + Blue =cyan —Blue + Red = Magenta —Red + Blue + Green=White  Answer Questions 2a&b in the Investigations Manual

Developing An Experiment  How do you think the color filters work?  Why are your clothes the colors they are? —Are they always that color? —What about crayons?

What Did You Learn?  What do you notice about the light coming out of the filter compared to the white light?  Answer Questions the questions in part 4 of the Investigations Manual  What happened to your picture?

Summary  How can three colors be responsible for all the colors we see? —How does the eye see colors?  What are the differences between the RGB color theory & the CMYK color theory?
