Stage-9 learners observed the effect of light on growth of cress seedlings. The activity involves close monitoring the growth of seedlings and measuring the height of plants after every 2 Days. Two petridishes were taken and cotton was placed. Few drops of water was put over cotton and then few cress seedlings were sprinkled. Then one petridish was placed in light conditions and other petridish was placed in dark conditions. Water was dropped regularly in both petridishes.
