Conducting experiments
What role does the scientific method play in ecology?
It is used by ecologists to understand the natural world
What is the purpose of deriving predictions from a hypothesis?
To test the hypothesis
In a manipulative experiment, what does the ecologist carefully manipulate?
Only the variable being measured
When conducting a mensurative experiment in the field, what does the ecologist rely on?
More observations
What happens if the data agree with the predictions made from the hypothesis?
The initial hypothesis is confirmed
What does the ecologist do if the data disagree with the predictions made from the hypothesis?
The ecologist starts over with a different hypothesis
When starting over with a different hypothesis, what often happens?
New observations and questions are developed based on what was learned
What does the ecologist measure in a mensurative experiment?
The amount of seagrass and seaweeds available to dugong in the wild
What is the main difference between a manipulative experiment and a mensurative experiment?
Whether or not the variable being measured is manipulated
What role do predictions play in designing an experiment?
They guide the design of an experiment to test the hypothesis
What happens if an ecologist cannot manipulate the variable being measured?
They conduct a mensurative experiment instead
