Materials: grow lights; radish seeds; small metal trays; soil; unbleached paper towels; water IV. Procedure A. Experimental Group Set up: 1. Crumple up three small pieces of paper towels in the bottom of a small pie pan 2. Trim another paper towel the shape of the pan to lay flat over the crumpled paper towels. 3. Place 8 radish seeds on the top of the paper towel. Make sure they are spaced out. 4. Use a water dropper and soak the paper towels and seeds. B. Control Group Set up: 1. Fill pie tin with moist potting soil 1 cm below the top edge of the pan 2. Poke 8 small, evenly spaced 1 cm deep holes in the soil. 3. Drop one seed in each hole and cover it up with soil 4. Use a water dropper to soak in the seeds. It should be wet but not drippy. V. Observations: Make a colored and labeled sketch and at least 2 written observations.
