Activity #3: Constructing a master location map using transects and stations – Student groups
In the field, scientists take samples in a methodical way along the same transect lines and station sites. Data are often presented on a map of the study area. For studies that cover a large area, data collecting stations can be plotted by latitude and longitude. The class will construct a master map with transects and stations labeled. This map will be used for Activities #4 and 5.
Each student will:
- Use latitude and longitude to plot his/her station location(s) on a master map.
- Grades 6-8: G-6-M
- Grades 9-12: G-3-H
- Skills: Measuring, communicating, geography, interpreting data, math, formulating models and using data
- Station data sheets
- Pencils, colored pencils
- Graph paper
- Enlarged map of Louisiana’s offshore area with grid and longitude and latitude labeled.

- Each student plots and labels his/her station location on the class master map. These locations will be used for Activities #4 and 5.
- Students will check station plots for correct location.
Note: When you are mapping, remember, the latitude and longitude on the data sheet are presented as degrees, minutes and hundredths of a minute only. For example, 28: 52.56′ reads 28E and 52.56 minutes (not 52 minutes and 56 seconds).
