Virtual lab: Light intensity and photosynthesis

Aim: find how the distance of a lamp (light intensity) affects the rate of photosynthesis in pondweed. Press the button to carry out each step of the method.

Follow the method one step at a time, or use the buttons above to finish it for you.

    Results

    Relative light intensity = 1 ÷ distance² (Higher tier: the inverse square law).

    Graph: rate of photosynthesis against distance

    The graph will be drawn when you reach that step.
