Control Variables

What colored bands (in order, bottom to top) did you find in your leaves? Did your “non-green” leaves still contain chlorophyll, or did they rely on other pigments entirely? If you had two different colored leaves from the same plant, do your results show you which pigments caused the difference?

3. Problems You Solved (Or Didn’t)
What problems did you encounter during these experiments and how did you solve them? If you didn’t come up with a solution, what seemed to be blocking you?
