1. Intro Question: How does your watershed impact the ocean? 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 8 th grade student. 3 min Water Cycle Tour (review) 4 min Discovery: Watershed Dynamics (how water flows) 5 min Hudson River Watershed Draw flow of river into ocean 5 min Looking at plumes 5 min Hudson River Plume 2 min Looking at an SST map 5 min

2. Comparing drawings 5 min Why does the river plume stay together in the ocean? 5 min Discovery: Density 10 min Check for understanding quiz / journal entry on different densities of fresh and salt water 5 min Find the Plume On paper 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. For Sage: break after slide #17 Land use along Hudson River 3 min Discovery: The Hudson River Watershed 5 min

3. See how farms are along the river and cities at river forks 5 min Activities that impact watershed ~ rollovers 5 min What local areas could be polluting your rivers? 3 min Pollution Solution: reading Pollution is carried in the river plume Discover Water the Universal solvent reading 1 min Eutrophication process 15 min End of day 2 ~ readings can be printed for homework

4. Discovery: Dead zones Discovery: NJ dead zones 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. 30 min For students who finish, they can visit the current ocean temperature (SST link)
