Optimal Watering for Healthy Bean Plant Growth: An Experimental Study

This study investigates the best watering frequency to promote healthy growth of green bean plants from seeds. The hypothesis proposed that watering every six days would yield the best results. Materials used included green bean seeds, measurement tools, pots, and potting soil. Over a two-week period, six plants were watered at different intervals while their growth was measured daily. The results showed no clear trend in growth, indicating that the hypothesis was incorrect. The findings challenge assumptions about optimal plant watering.

  1. How Tall Can You Grow? Henry Weiner

  2. Problem • How often should you water so that you can grow bean plants from seed?

  3. Hypothesis • I predict that watering every six days will work best to produce a healthy bean plant from seed.

  4. Materials • Green bean seeds • Liquid measuring cup with 1/8 cup markings • Pots to plant seeds in • Drill to drill holes in bottom of pot • Catch pan • Ruler with metric system • Water out of the tap • Sunlight • Potting soil

  5. Procedure • Gather all materials. • Use drill to drill three holes 3/8 inch in diameter. • Plant 3 seeds in each cup in soil about 1 inch under the surface. • Put cups in catch pan to catch runoff. • Water all of the plants with their respective times of watering • Water with the watering schedule • Measure every day with centimeters. • Record on spreadsheet. • Continue for 2 weeks. • At end of experiment, make graphs.

  6. Results

  7. More Results • Plants 4 and 5 didn’t grow. Plant 1 was watered everyday; Plant 2 every 2 days, and so on.

  8. Conclusion • My hypothesis was incorrect. I predicted that the trend would go from plant 6 to plant 1. However, there was no trend in the data. Plant 6 grew first, but then plant 1 grew, causing it to have no trend.
