Flow Rate: Flow rate= Distance / Time
 For example, If the distance was 100ft and the time it took the bottle to float the distance was 1 min, then the flow rate would be 100ft/min.


Elevation of River bottom:
 Elevation was found by using two poles with 6 inch distance marks on each pole. Then a string was attached to the poles. To find the distance the poles were place away from each other at the length of the string. Then the string was adjusted to find the elevation inclines or declines along the river bottom.

Clam collection data:
  In order to get clams, we shoveled river bottom into the sequentially smaller nets. The bigger objects, like the clams were filtered out and we were able to observe them.

Choropleth map showing the number of individuals living in poverty.
This type of map is uses colors and different shading to represent a concentration 

Proportional symbol map  
showing population concentrations in Georgia 2000.
This type of map us usually used to represent the population of either humans animals or other populous beings. The larger the symbol, the larger the population of measured item.


Dot Density map showing where non-metro poor are located
This type of map is usually used to show concentrations of populations. The map uses the same size dot compared to the proportional map that uses different sizes.

Isopleth map of the United States.
This type of map uses contour lines to show different values and dimensions. The most common of these types of maps are topographic, and use lines to represent elevation.
