Background

The prairie is sectioned into plots. Some of the plots have grass and flowers in them and some only have grass. Our question was : have flowers spread from the original plots they were in?

Evidence

Figures 1-5 show the percentage of plots that have each plant in them from the data we collected.

Figure 1: Percentage of plots studies with and without Sage

Figure 2: Percentage of plots studies with and without American aster

Figure 4: Percentage of plots studies with and without american pokeweed

Figure 5: Percentage of plots studies with and without sunflowers

Figure 6: Diagram of the plants observed.

Reasoning

The types of flowers that seem to spread the most are sunflowers, american asters, and new england aster.
