Changing Hudson Project

Macroinvertebrates

Resource Type: 
Grades: 
9-12

A basic overview of invertebrates found in an aquatic ecosystem. 

Water Chestnut

Resource Type: 
Grades: 
9-12

This reading includes basic ecology of the water chestnut, along with information about the invasion of this plant in the region. 

Zebra Mussel Fact Sheet

Resource Type: 
Grades: 
9-12

Students will learn about the zebra mussel invasion and zebra mussel ecology. 

Invasive Species Reading & Questions

Resource Type: 
Grades: 
9-12

A general overview of invasive species. 

Watersheds

Resource Type: 
Grades: 
9-12

Students read about the Hudson River watershed. 

Tides

Resource Type: 
Grades: 
9-12

An overview of how the tides change in the Hudson River estuary. 

Change and the Hudson River

Resource Type: 
Grades: 
9-12

A brief reading summarizing major changes in the Hudson River watershed, including a discussion of when an ecosystem "bends" and "breaks". 

The Hudson Valley: A Social-Ecological System

Grades: 
9-12

In this module students will learn how land use has changed in the Hudson River watershed, both in geologic history and in more recent times in response to human pressures. Lessons include using paleoecology to understand change since the last glaciation, and using macroinvertebrates as an indicator for ecosystem health as it relates to land use.

Weather, Climate, & Climate Change

Grades: 
9-12
Topic(s): 
Nature of Science
Carbon

Extreme weather plagues many parts of our region, and can have significant impacts on the tributaries flowing into the Hudson as well as the Hudson itself. Climate change predictions are that, in the northeastern US, we will see more precipitation, less snow and possibly more large storms. No matter where you live, increased storm flow rates impact waterways and low-lying areas that were and probably still are flood plains. Students will investigate the physical and chemical parameters of a waterway, discuss the impact of different types of land cover, and use data from Wappinger Creek collected before, during, and after a storm to examine the effects of storm water on a small stream. They will also be able to investigate the impacts of a warming Hudson River on various aquatic organisms, the impact of climate change on the Hudson River's flow rate, and the implications of more frequent hurricanes.

Invasive Species

Grades: 
9-12
Topic(s): 
Water
Biodiversity
Nutrients & Energy
Nature of Science

Invasive species pose a serious risk to ecosystem health and stability around the world and locally. Why should we be concerned about invasive species? How do they change local plant and animal communities? How do they change the chemistry of a water body like the Hudson River?   Students will learn how and why invasive species have such large ecosystem impacts and how they have changed the Hudson River. This unit includes a more in-depth investigation of three species: zebra mussels, water chestnut, and common reed.  As students will discover, all of these introduced species have changed the ecosystems around us in potentially positive and negative ways.  The concluding research report provides an opportunity for students to explore other local invasive species.
