- 3.In an investigation designed to determine the effect of the amount of water on plant growth, two groups of equal-sized bean plants of the same species were grown under identical conditions, except the amount of water they were given.

It was determined that the plants watered with 400 mL of water once a day showed more growth.The independent variable in this investigation is the...
