For a plant to grow healthy and strong it needs light, water, and fertile soil to grow in, but what happens of the light it gets is not enough? Is there an optimum level of light that the plant must have to grow well? In this science experiment we are going to use three plants of the same kind and roughly of the same size to check this fact out.

Does the plant that gets less light grow more or less than the one which gets a whole lot more light? To make the experiment easier to control we will use just artificial light on all three plants. We will set the three plants in cubicles in similar pots, but we will vary the quality of light that each plant will receive. To do so we will use a 25 watt bulb, a 100 watt bulb and a 200 watt bulb.

Now make a record chart for your observations of each plant. Make sure that the lights are far enough from the plants so that the heat generated from them does not damage the plants. Observe the condition of the plants over a period of 10 days on a daily basis. At the end of ten days which plant is looking the healthiest? Look out for more science experiments here.
