Do plants need light?
Instructions
1. Place the paper towels around the inside edge of each jar 2. Place a bean seed between the paper towel and the side of the plastic jar 3. Wet the paper towels and place the jars on a sunlit window ledge until germination 4. After germination, place one jar inside a dark cupboard within the same room 5. The plant placed in the dark cupboard becomes white, grows poorly and dies first
You will need:
- 2 clear plastic jars - 1 packet of bean seeds - Paper towels - Water - 1 Dark Cupboard and 1 Sunlit Window
A green chemical called chlorophyll (....."Clo - ro - fill".....) changes sunlight into energy and sugar.
The plant in the dark cupboard loses it's green colour because sunlight helps to make chlorophyll. Without chlorophyll plant growth stops as there is no more energy or sugars being produced  |
