For the group studying soil pH, they will use pH testing strips to find areas of differing pH. In order to use the strips, they will dig a small hole and fill it with water and insert the pH strip into the pool. The survey of the species will be recorded right next to where the pH is recorded.
For the group studying richness of plants near vehicular traffic, they will find an area of grass right next to a road way, and then find an areas that are farther away from a road way. The groups will record the distance from which their areas are from a roadway.
The group studying the effects of pedestrian traffic will survey an area for a 15 minute time block and record the amount of people that walk through the area. The quantitative flow of people will give the group a gradient for them to compare the species richness to.
The group studying how different amounts of sunlight and shade affect the species will find areas that have certain known intervals of sunlight and shade. For example, the group will find an area that has 6 hours of light or shade, 8 hours of light or shade, and 10 hours of light or shade. The different amounts of light and shade will give the group values for them to plot the species richness against.
