What is a Biblical or Christian Worldview?
It is a worldview that begins with God and accepts the Bible as His Word.
What is the Scientific Method?
It is an organized way of finding a workable solution to a problem.
What are the steps of the Scientific Method in order?
1. Define the problem.
2. From a hypothesis
3. Test the hypothesis
4. Classify the data
5. Choose and verify the answer
6. Predict Outcomes
When we define the problem in the scientific method, the problem must be _____________, ______________, _______________, and ________________.
observable, measurable, repeatable, fall within the limitations of science.
What is a hypothesis?
It is a simple, testable statement about the answer to a problem.
What two ways can we test a hypothesis?
What is a survey?
In a survey you obtain data by observing conditions that already exist.
What must you control in an experiment in order to achieve a good result?
What are variables?
They are factors or conditions that may vary.
What is an experimental variable?
It is the factors or conditions that are changed in an experiment.
What are the groups called that experience the experimental variable?
the experimental groups
What is the control group?
It is the group that does not experience the experimental variable.
Name some ways in which we classify data.
★ group or arrange the data
★ analyze the data
What are some ways that we arrange data?
What does verifying an answer mean?
It means obtaining more data in repeated experiments or surveys to make sure your results are repeatable.
What is meant by "the fall"?
