Water the plant or plants.
Place a clear plastic bag over all of the leaves.
Tie the bag loosely with string around the stem.
Leave in the sun for a day. If you are conducting this experiment inside with a potted plant, place it on a windowsill.
Have students record their observations in their journal.
