PROBLEM: Are plants able to live in an environment without the seemingly essential nutrients of soil?
             HYPOTHESIS: Seeing as how certain plants can grow only in certain soils, it seems unlikely that any seeds would mature to a full healthy adult.
             · Assembled three cups with the proper soil (none, gravel, and topsoil)
             · Placed seeds in the cups (5 each to make sure at least a few of them sprout)
             · Placed 30 milliliters of water in all three cups (the amount of water will be the same and consistent throughout the experiment)
             · Removed seeds that didn't sprout in 5 days
             · Checked each seed for growth with ruler each day and recorded data
             · Added 5 milliliters of water each day
             Average growth per day for the plants with no soil, gravel, and topsoil is (in that order):
             Day No Soil (Height in cm) Gravel (Height in cm) Top Soil (Height in cm)
