Which type of water makes soybeans grow fastest?

Supporting files

The purpose of the project is to determine which type of water makes soybeans grow the fastest when watering the plants with tap water, calcium water, and distilled water. The hypothesis states that the soybeans watered with calcium water will grow the tallest. The materials needed include soil, soybean seeds, distilled water, tap water, a beaker, and TUMS®. The project was started by putting the soybeans in soil. It is important to water 30 plants, 10 soybean plants for each variable with 30ml mixture of calcium water, distilled water, and municipally treated tap water every other day. The calcium mixture was created by mixing up 1 TUMS® in 250 mls of municipally treated tap water. Next the soybeans were measured every week, then the data was recorded.. The hypothesis was supported, in 5 weeks calcium watered soybeans averaged a height of 35 centimeters, distilled watered soybeans averaged a height of 34 centimeters, and tap watered soybeans averaged a height of 12 centimeters. Even though there were holes for the water to drain the plants were overwatered and died. This experiment will help people know what type of water makes the soybean plant grow the fastest. Also knowing what type of water solution the soybeans need will help the soybeans get more nutrition.
