African violet plants are grown for their delicate, colorful flowers and furry, soft leaves. people often want to touch the leaves and brush the hairy leaves with their fingers. growers and plant owners were concerned that this could negatively affect the plant. of particular concern was the presence of body lotion or other skin products on the hands of persons touching the leaves.
a student thought this might be the basis of a science project. he selected two african violet plants. ten leaves on each of the two plants were brushed with a gloved hand for 30 seconds, once a day, for a period of five days. the difference was that leaves of the second plant were brushed with a gloved hand that had hand lotion applied to the glove.

as part of the peer review process, evaluate the student’s experiment. as part of your evaluation, be sure to:
• state one possible hypothesis for the experiment proposed by the student [1]
• describe the type of data that should be collected to determine if the brushing with lotion was having a negative effect on the african violet plant
