To change students negative attitudes toward science into positive. To observe the effect of light on plants. Illustrate the exchange of gases between the atmosphere and the plant. To understand how green plants use the sun's energy to produce food through photosynthesis. To see that plants are part of many natural cycles.
Plants provide a renewable source of food energy for many forms of life.
Green plants utilize the sun's energy and the gases in the atmosphere to produce food through photosynthesis and exchange gases in the atmosphere in the associated process of transpiration. Have each student make an illustrated log of events for germination of the seedings to the end of the experiment. Keep covering them with warm tap water. Keep covered with warm water and in a indirectly lit place. Sprinkle water over the top of the soil until the soil is well saturated.
