High school experimentation during the study of botany generally includes observing photobiological processes. These might include photosynthesis, phototrophism and photoperiodism. Experiments with these processes often involve exposing a plant or plant tissue to a light source covered with a piece of colored cellophane or plastic. Measurement of the light intensity at a specific wave length is often necessary.
