Changing Hudson Project

Exploring Abiotic Changes due to Zebra Mussels

Resource Type: 

Students will know how the zebra mussel has changed the Hudson River ecosystem and be able to explain how a biotic change affects the abiotic conditions in the Hudson River.

Exploring Population Change due to Zebra Mussels

Resource Type: 

Students will know how the zebra mussel invasion affected the food web of the Hudson River and be able to explain at least two connections within the food web that were affected using evidence from

Introduction to Zebra Mussels

Resource Type: 

Students will know what lives in the Hudson River, and will be able to create a food web drawing to represent the organisms living in the river.

Ecosystems in Action: Population & Community Dynamics

Grades: 
9-12
6-8
Topic(s): 
Water
Biodiversity
Nutrients & Energy
Nature of Science

How do populations change in the Hudson River ecosystem, and how do these changes affect the larger ecological community? Using video, data, and hands-on investigations, students will explore how food webs and the abiotic resources and conditions of the ecosystem have changed in response to the zebra mussel invasion. This case study allows students to understand community level changes, which they can then apply to other systems.  

Natural Selection at Foundry Cove

Resource Type: 

Students will know that environmental changes act as a selection filter and be able to explain these processes using the example of cadmium resistance in Foundry Cove mud worms.

Survivors at Foundry Cove!

Resource Type: 

Students will know that mud worms at Foundry Cove evolved cadmium resistance and be able to explain how the scientists verified that cadmium-resistance is an inherited trait.

Biomagnification

Resource Type: 
Grades: 
9-12

Biomagnification: Cadmium in the Food Web

Resource Type: 

Students will know the concept of biomagnification and be able to explain how biomagnification relates to cadmium levels in blue crabs in the Hudson River.

The Marathon Battery Factory

Resource Type: 

Students will know how Foundry Cove became the most cadmium-polluted place in the world and will be able to explain the impact on the ecosystem.
