Hypothesis and VariablesOur hypothesis states that by the water drain

outside of the school has more weeds growing on it on one side, than on the other.

INDEPENDENT VARIABLE: Distance from drain, side of drain.

DEPENDENT VARIABLE: Amount of weeds.CONSTANTS: The amount of weeds in an area

(6 in).

Analyzed Data Graph

ConclusionWe found that our graph supports our

hypothesis, that one side of the drain favors weed growth. When analyzing our graph, you can see that on the left side of the drain, there is more weeds, than on the left, whether it is because of room, sunlight, or soil, we are unsure.

What We Would ChangeIf we were to redo our experiment, we would

find a larger area. We would include soil and water and light as factors, and record them as well. We would also put more time into our research, so that it can be more reliable.
