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