				(red & blue) (red & yellow) (yellow & blue)

Research
Suggested topics to research are the spectrum, color, art, and blending of colors.

Hypothesis

1. If I mix _________ and _________ together, I will get the color _________.
2. If I mix _________ and _________ together, I will get the color _________.
3. If I mix _________ and _________ together, I will get the color _________.

Procedure

1. Gather all materials.
2. Fill three test tubes 1/2 full with water.
3. Use the marker and label each test tube "A," "B," and "C."
4. Place 5 drops of red food coloring in test tube "A."
5. Place 5 drops of blue food coloring in test tube "B."
6. Place 5 drops of yellow food coloring in test tube "C."
7. Allow the color to mix thoroughly. A gentle shake will help to mix them faster.
8. Use the marker and label the remaining three test tubes "D," "E," and "F."
9. Pour 1/2 the water from test tube "A" into test tube "D."
10. Pour 1/2 the water from test tube "B" into test tube "D."
11. Place thumb over the opening of the test tube and gently shake.
12. Record your observations on data chart.
13. Pour remaining water from test tube "A" into test tube "E."
14. Pour 1/2 the water from test tube "C" into test tube "E."
15. Gently shake and record observations in data chart.
16. Pour remaining water from test tubes "B" and "C" into test tube "F."
17. Gently shake and record observations in data chart.
18. Color in the test tube with the appropriate color.
19. Draw conclusions and discuss.
