IF PLANTS CAN GROW WITH OUT LIGTH

 Plants and light seem to be good buddies, but how far does the friendship really go? While a lot of plants grow happily underneath warm, sunny skies, the light of the sun might not be necessary for growth and health. Do you think you could grow a plant in darkness? Try out this simple and fun experiment to find out how important -- or unimportant -- light is to a plant.

Problem:

Do plants need light to grow? No because if you put three pots that have one bean in each and the same amount of soil and water it will grow and start to sprout without sunlight and it will slowly die.So technically it will grow but it well die.

Materials:

• Six bean seeds
• Six pots
• Plant sprayer
• Potting soil
• Shelf
• Cupboard
• Ruler
• Notebook
• Pencil

Procedure:

1. Fill each pot with soil.
2. Plant one bean seed in each pot. Make sure you gently cover each seed with a shallow layer of soil.
3. Place three of the pots outside in a spot that receives lots of sunshine. If the weather is too stormy or overcast, position the pots under a grow light.
4. Place the remaining three pots in a dark cupboard.
5. Think about what you know of plants and light. Why do you think plants might need light? Why do you think they might be able to do without it?
6. Remember the question of this experiment: Do plants need light to grow? Write down your guess, often called a hypothesis, in your notebook.
7. Spray all your planted seeds gently with the mister.
8. Now it's time to wait. To get the best results, you'll want to observe your seeds for at least three weeks. Make sure you use the mister every couple of days.
9. At the end of each week, take a close look at each of your pots. Write down what you see in your notebook.
10. Once a full three weeks have passed, read through your notes. Did the absence of light make a difference?
