<b>Methods:</b> 1)The experiment was conducted outside in the grasslands. 2)The variables were: number of different species, abundance of species, percentage of vegetation in quadrant, and percentage of grasses in quadrant. 3)Materials used: i) 1m*1m quadrat, ii) pencil, iii) paper, iv) students, v) eyes 4)The quadrant was used to sample 25 random plots of land in the grassland. The quadrant’s dimensions were 1m*1m=1m^2. 5)The number of species data was collected by identifying each different plant specie that was located within the quadrant. The data was verified by moving around the plants, and getting a feel for them to see if they were really different. This was further crosschecked with the lab manual to see which plant matched most closely to the ones listed in the lab manual and to truly verify if the plants being identified were different. 6)The total abundance of plants was identified by various steps. First the plants of the same specie were summed. Secondly the sums of the different species were added to get a total of the plant species in the area. How ever since grass is also considered a specie, quadrants within the quadrant were used with dimensions 10cm*10cm. The roots of grass were counted in that smaller quadrant and the data was extrapolated for the entire quadrant by multiplying the number of roots by 100.<b>Hypothesis:</b> There is a correlation between plots having greater quantities of other plant species and less grasses due to lack of space and resources for the grasses to thrive.<b>Predictions:</b> 1) As the number of other species of plants in the quadrant increased, the number of grasses in the quadrant decreased.2) As other plant species grew taller, grasses grew shorter.3) As other plants grew greener, more grasses died out.4) As more grasses grew, other plant species were smaller and weaker.<br>
