Scientific Method Review (Breakout Session)

When experimenting with the growth of a plant, a scientist uses three (of the same type of) plants, two different fertilizers, equal light, and equal water. What type of variable is the fertilizer?

• Dependent
• Independent
• Control
• Compound

An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, the independent variable is ...

• The type of plant
• The amount of sunlight
• The type of music
• The type of liquid

An experiment is being done to determine how light affects the growth of small zinnia plants. One plant is placed in full sunlight, the second in a shaded area, the third in an unlit closet. The hypothesis of this experiment could be:

• Plants grow differently under different conditions.
• Zinnia plants in direct sunlight grow taller than zinnia plants in little or no sunlight.
• Many things, including sunlight, affect the growth of a plant.
