That's because monitors use additive colors and printers use subtractive.
This lab consolidates labs on subtractive and additive color. I knew there was a difference, but when studying color, I didn't find a lab that helped students to compare the two. Comparing additive and subtractive colors You don't need any materials for the section on comparing additive and subtractive colors. Refraction of Light activity Materials needed three beakers or mason jars3 straws Light moving through a Prism Flashlightprismwhite paper Here's another simple one.
Effects of colored light on what we see Materials needed: This is the part of the lab I like best. Out on the table for students to play with. List of Free Science Books. Dimensional Analysis. Newton's 1st Law Of Motion.
