My class has been learning about plants. For this project we had to come up with a question we were wondering. I wanted to know, what would happen to a plant if I put it in the closet, instead of under the light. My hypothesis was that if I put a plant in the closet, then the plant would not grow as tall because plants need sunlight to grow. For this experiment I had two plants, one was a control, with all the variables to grow a perfect plant. For the control plant I used seeds, soil, fertilizer, water and light. The other was a manipulated plant, that is the one that I am putting in the closet. For my manipulated plant I changed the light. I am looking to see if the amount of light will change the height of the plant.
After the first week I am noticing several things. First, my control plant is growing! It has 4 separate plants, each with 3 leaves. They are green and are about 2 cm tall already! The soil is light brown and moist from my watering it daily. Every day the plant grows about a half a cm. I wonder what will happen next! My manipulated plant is also growing, just differently. The plant is tall, but light green and not as many leaves. The soil is the same color as the control but the stem is thinner and less green. I wonder why?
This is my controlled experiment. This picture was taken on Monday, May 8th. It has been growing for about two weeks.
This is my manipulated. The sugar water is keeping the plant from growing.
