Intro Question: How does your watershed impact the ocean

1
Each adventure is designed to have a main theme
(or thread) with additional information available
as Discoveries (more details about the
content).Recommended discoveries have an arrow
adding them into the main thread. As the teacher,
you will decide which Discoveries your students
should take. The times are listed as
approximations for a typical 8th grade student.

This would be the stop point of day 1 about one
class period if you included the SST and
Discovery Density. Find the plume could be
printed for homework or done in class the next
day. This activity uses temperature and salinity
to locate the edges of the river plume.
Reinforcement of plotting coordinates, but can be
omitted without losing content.

Student assessment student writes an essay in
their journal online how each person in the
picture is affecting their watershed and how this
pollution may impact the ocean. Focus on essay
construction and use of scientific information.
