Explore how the colors in white light can be absorbed and reflected. Shine a white light through colored filters onto a colored object. Investigate how the filters absorb some colors and let others pass through. Use different combinations of filters to block primary colors. For example, make a tomato look black by using a cyan filter to block red light from shining onto it. This learning object is one in a series of two learning objects. The series is also packaged as a combined learning object.
Objective
Students identify that colored filters selectively absorb colors.
Students identify that the three primary subtractive colors are magenta, cyan and yellow.
Students predict the result when subtractive colors are filtered onto colored objects.
Students explore the range of colors produced by combining different ratios of the three primary subtractive colors.
