Question

the passage below describes an experiment. mark planted one tomato plant in each of nine identical pots. he placed three plants in soil that had a ph of 5.0, three in soil that had a ph of 6.5, and three in soil that had a ph of 8.0. he placed all the pots in a section of his backyard that gets direct sunlight for six hours each day. he gave each tomato plant three cups of water per day. over the course of one month, mark counted the number of tomatoes that each plant produced. identify the question that the experiment can best answer. is the amount of time that tomato plants live affected by soil ph levels? do soil ph levels affect the number of tomatoes a tomato plant produces?

Explanation:

Step1: Identify the research - interest

The experiment is about tomato plants.

Step2: Determine the variable of interest

The variable is soil pH levels and its impact on tomato - production.

Step3: Formulate the question

The question should focus on the relationship between soil pH and tomato yield.

Answer:

Do soil pH levels affect the number of tomatoes a tomato plant produces?
