Color Pigments - Questions
The Color Pigments Concept Builder is comprised of 33 questions. The questions are divided into 15 different question groups. Questions in the same group are rather similar to one another. The Concept Builder is coded to select at random a question from each group until a student is successful with that group of questions.
There are three different activities that can be engaged in through the Concept Builder. Those three activities are differentiated as follows:
- Name That Pigment: Question Groups 1-6 ... Learners identify the pigment present in a sheet of paper from observations of the papers color appearance when two different light colors shine upon it.
- Fashion Show: Question Groups 7-12 ... Learners determine the color appearane of a shirt when they are given the pigments that it contains and the incident light color.
- Gum Drops: Question Groups 13-15 ... Learners determine the printer inks - cyan, magenta, and/or yellow - that must be applied to various parts of a color image in order to produce the desired results.
The questions from each group are shown below. The activities can be done independent of each other. That is, Activity 2 is not dependent upon having done Activity 1. Teachers are encouraged to view the questions in order to judge which activities are most appropriate for their classes.
