Plant Experiment Reflection #2

My group’s question was: What happens if we use no fertilizer pellets? Our hypothesis was: If we do not give fertilizer pellets to the plants then it would take longer to grow and would not grow as well because the fertilizer pellets help them grow faster since it gives it food.

After two weeks my control plants have grown a lot! It grows about one to two centimeters a day. All of the quads are the color green. All of our plants are growing expect two. Those two are wilting. They are almost dead. The direction of most of our plants are standing upright. Now our plants has buds! There have been a lot of changes so far. In the beginning it was only about two or three centimeters. Now our highest plant is ten centimeters! Our control plants are doing really well.


For our manipulated plants we didn’t use any fertilizer pellets. After two weeks so far the manipulated plants are looking pretty well. Our tallest plant is one centimeter less than our tallest control plant. All of our plants are green. One of our plants is nine centimeters. All twelve of my plants are growing. It is also growing about one to two centimeters a day.

Based on the results our hypothesis was partly right. It was partly right because it is shorter than our control plants but it is only one centimeter shorter. I think this happened because the manipulated plant had all of the important things it needed, which were soil, air, sunlight and water. Plants in the real world get a lot of sunlight, rain and air that helps them grow. Fertilizer pellets are not that necessary.
