A scientist wants to test the effect of watering on a new species of plant. He leaves three plants outside. The first one he gives no water to. The second he waters once a day. And the third plant he waters 3 times a day. After a week the plant that was watered once a day is thriving while the others are wilted. Identify the independent and dependent variables.
IV= water DV= plant growth
