How is the investigation of the Hudson River ecosystem an example of scientific inquiry? Scientists study the natural world through scientific inquiry. This involves:
• Asking questions
• Developing and using models
• Planning and carrying out investigations
• Analyzing and interpreting data
• Using mathematics and computer technology
• Constructing explanations
• Engaging in argument from evidence
• Obtaining, evaluating, and communicating information

The investigation of the Hudson River is an example of scientific inquiry because it develops testable questions such as this; How might a zebra mussel invasion affect  the Hudson River ecosystem?

All the other elements of scientific inquiry were applied.

Explanation:

Developing and using models: Scientists developed ways to check for changes in the river using the data available to them.

• Planning and carrying out investigations: Several scientific institutes have planned and carried out investigations to determine reasons for the return of the Zebra mussels.

• Analyzing and interpreting data: Graphs are plotted to evaluate to draw a relationship between the zooplankton and the Zebra mussels.

• Using mathematics and computer technology : Mathematical measurements were done to analyze the sizes of the Zebra mussels.

• Constructing explanations : Explanations were proposed as to why the Zebra mussels were not eating up them. It made sense to them that more Zebra mussels would result in more Zooplanktons

• Engaging in argument from evidence : They could argue from the evidence that blue cobras were eating up the Zebra mussels

• Obtaining, evaluating, and communicating information: After scientists have obtained their information, they endeavor to communicate them by publishing them in scientific papers and journals.
