Experiment to Grow a Sweet Potato in Water:

  1. Materials Needed:

    • One sweet potato
    • A glass jar or container
    • Water
    • Toothpicks
  2. Procedure:

    • Select a healthy sweet potato.
    • Insert 3-4 toothpicks around the middle of the sweet potato to suspend it in the jar.
    • Place the sweet potato in the jar with the pointed end down and the wider end up.
    • Fill the jar with water, covering the bottom half of the sweet potato.
    • Place the jar in a sunny spot, such as a windowsill.
  3. Observations:

    • Week 1-2: Roots begin to develop from the bottom of the sweet potato submerged in water.
    • Week 2-4: Shoots or sprouts start emerging from the top part of the sweet potato.
    • Week 4-6: The shoots grow longer and develop into vines with leaves.
    • Maintenance: Ensure the water level is maintained, changing the water every few days to prevent stagnation and mould growth.

Conclusion:

  • Sweet potatoes can successfully grow in water, with roots forming in the submerged portion and shoots/vines growing from the exposed portion.
  • Regular maintenance, such as water changes and adequate sunlight, is essential for healthy growth.
