Cindy wanted to find out how the amount of sunlight affects the growth of plants. She placed two tomato plants in 10 inch pots with potting soil and watered them ¼ cup each day. One plant was placed under a cardboard box and one was placed in the sunlight. She measured the growth of the plant each week for three weeks.
What is the dependent variable?
Using the same type of plant
Each plant was placed in a 10 inch pot
The growth of the plant
One plant is in the sunlight and the other is under a box
