Examining the effect of watering on plant growth
The experimental data and analyzed results support our hypothesis that the greater the amount of water, the faster the growth rate, but only up to a certain point. If too much water is given to the plants, their growth rate fell.
Research shows that too much water in the soil is detrimental to plant growth, as wet soil tends to cover a plant’s root with water and therefore deprive it of oxygen. This cause the roots to rot will eventually lead to the death of the plant.
What would happen if this science fair project was repeated using other species of plants such as corn and green peas?
The experiment can be repeated by placing the pots under a shade or directly outside under the sun.
