5. Students hypothesize that temperature is a limiting factor for the germination of seeds. They carry out an experiment to
test their hypothesis. They label two plastic bags A and B and place a damp paper towel and one bean seed in each bag.
They place one bag in a lighted refrigerator and the other bag on the windowsill. Whenever the paper towels look dry, they
add more water. Each day they check to see if the seeds have germinated and record their observations in a data table.
