Practical - Light Intensity and Photosynthesis Rate

The video tutorial explains an experiment to study how light intensity affects the rate of photosynthesis in pondweed. It covers the setup, including the use of a lamp and hydrogen carbonate solution, and details the independent, dependent, and control variables. The procedure involves measuring oxygen bubbles produced at varying distances from the light source. Results are recorded in a tally chart and analyzed using a scatter graph, showing that increased distance (decreased light intensity) reduces photosynthesis rate.
