Observing Plant Growth
Plants will grow towards sunlight.
Plant some seeds in 2 separate paper cups of soil – make sure the cups have holes in the base and a tray to sit in to catch the water.
Leave one cup in full sunlight and put the other in a shoebox. Cut a hole in the top of the box at one end so sunlight can get through. Place the plant in the box at the opposite end to the hole.
What happens? Does the seedling in the box still grow towards the sun?
