Dependent and independent variable 2

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. What is the independent variable in the experiment?

• the amount of light
• the type of plants
• the type of soil
• the length of the experiment

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.
