2. Hypothesis and Variables
Our 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).

5. Conclusion
We 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.
6. What We Would Change
If 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.
