Master scientific variables! Learn to identify independent, dependent, and constant factors in experiments.

You decide to see if growing plants in different color light will make plants grow faster. You get two plants that are the same size, type, size pot, and with the same soil. You start with Plant A getting 12 hours of white light and plant B getting 12 hours of blue light. After 5 weeks, you measure the height of the plants; plant A is taller than plant B. Match the type of variable to the parts of the experiment. Blue and White light Experimental Groups Light Color Independent Variable Hours of light Constant Plant height Dependent Variable Will a higher calorie lunch give an 8th grader more energy?

Calories consumed Independent Variable Amount of energy Dependent Variable 300 Calorie, 600 Calorie, or 900 Calorie lunch Experimental Groups Age of student Constant Match the correct vocabulary term with the definition. Independent Variable The variable that is getting changed in the experiment Dependent Variable The variable that is getting measured Experimental Groups The values for the IV Constants Factors that are kept the same
