A student conducted an experiment to test how light intensity affects the rate of photosynthesis. They measured the number of oxygen bubbles produced by pondweed at different distances from a lamp. List the independent, dependent, and two controlled variables.

Independent variable: Distance of the lamp from the pondweed (light intensity)

Dependent variable: Number of oxygen bubbles produced (rate of photosynthesis)

Controlled variables: Type of plant used, volume of water, temperature
