Put one tray in sunlight and one tray in shade, using different seeds and different amounts of water. Use the same kind of seeds, soil, water, and temperature, changing only the amount of light each tray receives. Put all seedlings in sunlight and measure the tallest plant at the end of the week. Use one seedling in sunlight and compare it with a different plant already growing in shade.
