Use paper chromatography to analyze the leaf pigments found in three different types of plants. R What is the effect of water temperature on the amount of color in spirogyra plants? S Why do leaves change color in the fall? R R R R R R R R R R R R How Does the Coloring and Sweetness of a Flower Affect Bee Visitation? R Is green the only color in a leaf? S Investigate whether the pigments in leaves that produced their autumn color are present while the leaves were still green. R Separate the colors of a green leaf using chromatography R Determine if there is one color that can be used to paint our cherry trees that will protect them from sunburn without causing harvest delays.

The Effect of Ultraviolet Light on Plant Development and Fruit Production
R
Applying ultra-violet visible spectrophotometry and various types of chromatography to compare the amounts of certain photosynthetic pigments in fresh, frozen, and canned phaseolus vulgaris and spinacia olercea. R Why do leaves change color in the fall? R R R R R R R R R R R R Predict whether self-pollination or cross-pollination with another plant with the same or different colored flowers will produce the most seeds. R R 1. What happens to pigment as leaves change color with seasons? 2. Why are two leaves of the same tree different in color intensity? 3. Does the temperature of a refrigerator have an effect on a plants pigment composition? 4 and 5. Compared different, yet similarly colored parts of the plant to determine whether or not the coloring pigment was the same.
