Hudson River Ecosystems

Learn about the dynamics of ecosystems through an authentic science experience.  How does human action, including commerce and energy production along the Hudson River, affect aquatic plants and animals.  Using mini-aquariums, students use instruments for data collection to solve a problem in a research simulation.

The program begins with a discussion of the impacts human activity has on the Hudson River.  After some instruction about how to use the testing equipment, students are put into 4 teams.  Each team has a water sample that has been taken from a place in the river where scientists have observed a problem such as loss of fish and plant life.  After making observations and proposing a hypothesis, their task is to compare their tank to a control tank of healthy water, measuring pH, salinity, turbidity and temperature in order to determine the cause of the problem.  The program concludes with each team reporting their data, determining if their hypothesis was proven and finally designing a new question to investigate based on their experimentation.
