Answer 1

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.
