Because oxygen is a product of photosynthesis and the Elodea plant is submerged in water, the oxygen is released in bubbles that rise to the surface of the water in the beaker.
In this experiment, the rate of photosynthesis for each degree of light intensity can be measured by counting the number of bubbles released every 30 seconds for five minutes at each distance.
The rate is the number of bubbles released per minute.
Organisms that use the process of photosynthesis to create sugar to use for energy have a greater rate of photosynthesis when the intensity of the light source is the greatest.
Background: Photosynthesis is the process by which photoautotrophs convert photons of kinetic light energy into potential chemical energy (food) by synthesizing glucose from water and carbon dioxide and releasing oxygen as a waste product.

Sunlight radiation travels in waves but acts like particles of energy called photons.
