Sientific method

Lying in bed you notice that you get cold every time your brother opens the door. This is most closely associated with which step in the scientific method?

• Conclusion

• Making an observation

• Forming a hypothesi

• Developing a test

What is the difference between a question and a hypothesis

• A question follows from an interesting observation and the hypothesis is an educated guess or answer to that questiony

• A question is what you end up with after the test and the hypothesis is a summary of the conclusions.

• A question is an assumption and the hypothesis is the answer to the assumption.

• A question is the summary of data collected and the hypothesis is the interpretation of the data

What is the first step in the Scientific Method?

• Test

• Hypothesis

• Observation

• Prediction

What is the last step in the scientific method?

• Hypothesis formation

• Observation

• Communication of results

• Conclusion

What is a hypothesis?

• Whatever the teacher tells you is the truth.

• Your best “educated guess” of what the answer to your question will be.

• An experiment

• An untestable statement.

How do you come up with a good question?

• From the predictions.

• Assume that you know everything.

• By testing the data.

• By making an interesting observation.

What is a prediction?

• Another word for observation.

• To force a conclusion based on many data.

• Just another word for a hypothesis.

• What you think will be the outcome of your experiment or data collection.

How do you make a conclusion?

• You look at your hypotheses and choose which one you like best

• You guess what the results should be.

• You keep making different tests until they show what you want to see.

• You compare the data from your experimental results to the prediction they tested.

What is the difference between a prediction and a test?

• A prediction is what a fortune teller gets paid for, and a test is what you give to your friends to make sure they are still your friends.

• A prediction is a possible answer to the question, and a test is what you take at the end of the semester in class.

• A prediction is usually a specific statement “if . . .then”, and the test is the actual experiment used to obtain data.

• A prediction is what the doctors gives you in her clinic, and a test is what the weatherman gives you each evening.

Why do you usually need more than one hypothesis for a question?

• Observations trick you into trying only one hypothesis.

• Hypotheses always come in pairs.

• A prediction always needs more than a single hypothesis.

• If you reject your sole hypothesis you have nothing left.
