Match

Match the parts of the scientific method with the correct step.

• Does sunlight affect the rate of photosynthesis in plants?

• Plants exposed to more sunlight seem to grow faster and healthier.

• Increased sunlight exposure increases the rate of photosynthesis in plants

• Set up controlled experiment with groups of plants exposed to different amounts of sunlight (full sunlight, partial sunlight, and no sunlight).

• Measure and compare the rate of photosynthesis by evaluating growth, leaf color, and oxygen production.
