Why Lesson Planet?
In this salt front of the Hudson River worksheet, 7th graders first read an excerpt about the lower portion of the Hudson River that is an estuary. Then they use a colored pencil to plot salinity data from the table shown on a graph, identifying where the salinity is the highest and the lowest. There are four more questions that pertain to their graph. Using the same graph, students plot the data from table 2 given and respond to four questions related to the location of that data.
