Introduction: During the process of photosynthesis, oxygen is released. The release of oxygen can be visibly observed in aquatic plants as bubbles. Counting the number of bubbles released over a period of time can serve as a measurement of the rate of photosynthesis. There are factors that can increase the rate of photosynthesis in plants. This simulation will explore those factors.

Procedure: You will change the variables and record the number of bubbles released in a minute. Use the clock and the start / stop buttons.

1. Make a prediction about what you think will happen: As you increase the light intensity, the number of bubbles will
