Scientific Method: Steps, Variables, and Hypothesis Testing in Biology

What is the first step in the scientific method?

Observation

What is formulated based on an observation in the scientific method?

A question

What is the purpose of a hypothesis in the scientific method?

To provide a testable explanation for the observation.

What must be defined when designing an experiment?

Independent and dependent variables

What is a prediction in the context of the scientific method?

An If/then statement that states what is expected to happen if the hypothesis is correct.

What is the general format of a prediction?

If [hypothesis], then [expected outcome on the dependent variable].

What is the role of the independent variable in an experiment?

It is the variable that is manipulated to observe its effect on the dependent variable.

What is the dependent variable in an experiment?

It is the variable that is measured or observed in response to changes in the independent variable.

What should you do after performing an experiment?

Analyze and interpret the data.

What can each experiment lead to in the scientific method?

The creation of new hypotheses to test.

Provide an example of a prediction based on a hypothesis about bee preferences.

If bees prefer some flower colors over others, then bees will visit brightly colored flowers more frequently than white flowers.

What is the significance of defining variables in an experiment?

It helps clarify what is being tested and measured.

What is the importance of analyzing and interpreting data in the scientific method?

It allows scientists to draw conclusions and make informed decisions based on the results.

What is the relationship between hypotheses and predictions?

Predictions are derived from hypotheses and indicate expected outcomes based on them.

What is an example of an observation that could lead to a scientific question?

Noticing that one tree's leaves are thicker than another's due to sunlight exposure.

What is the next step after formulating a question in the scientific method?

Construct a hypothesis.
