  1. The Affect of Magnets on Radish Plant Growth By: Austin Cia & Max Rabin 4th Period 2nd Quarter 2010 Robert Louis Stevenson Middle School

  2. Introduction Testable question: Will a radish plant grow towards a magnet? Hypothesis: If we put a magnet next to a radish plant the radish will grow towards the magnet because we think since a radish grows shorter next to a magnet then it will grow towards a magnet too. Background Information: -Radishes grow shorter next to magnets -Magnetism is the force that electric currents exert on other electric currents

  3. Introduction cont. • Experimental Variables: • One of the radishes will have a magnet next to it, and the other wont • Control Variables: • Same temperature, amount of water, pots, amount of sunlight, radish seeds, and soil.

  4. Materials • 6 radish seeds in each pot • 1 magnet that holds 100 pounds • 2 pots • 800 milliliters of soil in each pot • 1 2-foot piece of rebar • 2 feet of duct tape

  5. Procedure • Gather all materials: 2 pots, 1 magnet, 1 pack of radish seeds, 1 piece of rebar, duct tape, and soil • Put 800 milliliters of soil in each pot • Put 6 radish seeds ½ of an inch down in the soil • Get the piece of rebar and duct tape the magnet to the rebar. Then put the piece of rebar in the soil so the magnet is facing the radish. • Water every other day. • As it grows, if the radish grows towards the magnet, record how much every week.

  6. Observation & Data

  7. Data Graph

  8. Data Analysis • The plant with the magnet ended up not growing towards the magnet, but it did grow 1 cm. taller than the plant without the magnet. • Compare: Both plants grew straight up; Both plants looked the same • Contrast: The plant with the magnet grew 1 cm. taller than the plant without the whole time • The radish plant with the magnet grew 1 cm. taller than the radish without the whole time.

  9. Conclusion • Our hypothesis was incorrect because the radish plant with the magnet grew straight up • The rebar that was holding the magnet up was metal, so it might have affected the magnetic field • Instead of using a piece of rebar we would use a wooden stick • Our recommendations are that magnets don’t have any affect on plants
