7. Question #8-12 A scientist was conducting an experiment on whether plants grew better with fertilizer added to the soil. She set up 20 plants of the same type in the window and added fertilizer to 10 of them. She then made sure that all plants received the same amount of water and sunlight. She measured the height and number of leaves every week for 5 weeks. A scientist was conducting an experiment on whether plants grew better with fertilizer added to the soil.
