* A Knife * Water * A potato with buds or eyes * A stick or marker * A patch of dirt
Take the potato cut into half. Dig holes in the ground and plant the 2 halves of the potato with the eyes facing up separately, cover with mud and dirt and mark the 2 places separately with a stick or marker. Water one point immediately and continue watering it regularly, but do not water the other point. See the difference you find in both the points and find why there is a difference.
Water is essential for plants to grow and produce flowers and fruits.
The potato that was watered regularly grew and produced roots and baby potatoes under the soil, but the other potato piece under the soil and produced nothing.
