  1. Hypothesis- If plant U is placed in a box, then it will not grow as much as plant T because plant T is receiving more sunlight. Independent – Amount of sunlight Dependent- plant growth Base your answers on the picture and the information below. The two plants, T and U, were given the same amount of water and soil. However, plant U was placed in a box. Form a hypothesis. b. What is the independent and dependent variables?
