This will also allow you to watch germination. The process by which seeds sprout into plants is called germination. Conduct experiments to test the effects of light and dark on seed germination and plant growth. Keep both moist and at the same temperature. After a few days, count and compare the number of seeds that sprouted in each location.
Water evaporating out of plants is called transpiration.
To see transpiration, put a small plastic sandwich bag over a leaf or a few leaves on a plant outside. Return later in the day to check on your leaf. You should see moisture forming due to transpiration. Another way to watch movement of water in plants is to put celery or white carnations in containers with food coloring-dyed water. They will soak up this water and then you can see how quickly water moves up the stems and where it goes.
