How does the amount of sunlight on plant leaves affects plant growth? Take 3 of the bean plants that are about 7 cm tall. Record their heights. Carefully clip off the necessary number of leaves so that the plants all have the same number of leaves. On the first plant, cover half of the leaves with aluminum foil. Cover all of the leaves on the second plant with aluminum foil. Do nothing to the leaves on the third plant. Plant 3 is the control. On plants 1 and 2 be sure to leave the stems and stalks exposed. Record the height of each plant every day and comment and count any new leaves on each plant. Record this information on a data table of your own design. At the end of two weeks, graph the growth of each plant. Write a conclusion.
