| I think that the plant given chlorine will die much faster than the other plant. | |
|
What effect does chlorine have on a plant over the period of two weeks? I chose this question, because one day I was thinking about how people in the summer step out of their pools, and onto the grass. Then I started to wonder what would happen to the grass that was being exposed to the chlorine water. I decided that the best way to find out was to actually do the experiment. I thought that the plant exposed to the chlorine water would die much faster, than the other plant, that was only exposed to tap water. I thought this because it seemed that the chlorine had chemicals in it, and if chemicals are put into a plant daily, than naturally it would die. To start off my procedure, I had to buy the two packages of lettuce seeds. Then I brought them home, and I planted them in small pots. Then every other day, for two weeks, I would water plant A with 25% chlorine water, and plant B with tap water. Every time, I made sure I was giving the plants 1/4 a cup of their solutions. Then I, every other day took notes of their growth. My results were kind of funny. Neither plant grew at all. So I concluded that chlorine has no affect on plants, and that disproved my hypothesis. If I had another chance to do my experiment, I would start out a lot earlier, like two months ahead of my due date. That way, if my seeds didn't grow at all, I would start over, and I would not have to rush the experiment |

1. I bought 2 lettuce
seed packets
2. I labeled the 2 plant pots that I hed 3. I put exactly seven seeds in each plant pot 4. I watered the plant A with 25% chlorine water every other day. I watered plant B with tap water every other day. 5. I took notes of their growth. |

| Both plants didnít grow at all. They never became any more than seeds. | |
| The two plants did not grow. The chlorine didn't have any effect on the plants, because neither one grew any more than another. This disproves my hypothesis. | |
