Fast plants & root growth hormones by: Anna Lily & Izzy

EXPERIMENTAL QUESTION… What is the effect of root growth hormones on fast plants? Three days old Thirty-five days old

If we add root growth hormones then the plants will grow taller. OUR HYPOTHESIS… If we add root growth hormones then the plants will grow taller.

EXPERIMENTAL DESIGN… Our variable is the root growth hormones. We added two doses of RGH to the soil- for experiment one. We added four doses to the soil- for experiment two! RGH means root growth hormones (we made it up ) The yellow stuff is the RGH

TIME LAPSE

Results As you can see our experiment stopped growing around the 15th day at 4.5 inches. They stayed that way until they died.

COMPARISON TO CONTROLLED… 4.5 inches 6 inches 4.5 inches The controlled plant grew 6 inches and both of the experiments only grew 4.5 inches that means that RGH does not work on fast plants.

Conclusion Our hypothesis was that the plants would grow taller. Our data does not support our hypothesis, because our experiment was two and a half inches shorter than our controlled. We actually think that the RGH made our plants stop growing because in our data the plants stopped growing a lot sooner then our controlled.
