What is a hypothesis?

• Whatever the teacher tells you is the truth.

• An untestable statement.

• An experiment.

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

How do you come up with a good question?

• By testing the data.

• By making an interesting observation.

• From the predictions.

• Assume that you know everything.

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?

• Forming a hypothesis

• Conclusion

• Making an observation

•  Developing a test

All the things in an experiment that must be the same to make it fair are called

• controlled experiments

• dependent variables

• controlled variables or constants

•  independent variables

What is the first step in the Scientific Method?

• Prediction

• Observation

• Test

• Question

A scientist hypothesizes the the temperature at which an alligator's egg is incubated will determine whether the alligator will be male or female. The independent variable is...

• the male alligators

•  the incubator

•  the gender of the alligator

•  the temperature

What is the difference between a question and a hypothesis?

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

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

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

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

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

• Observations trick you into trying only one hypothesis.

• If you reject your only hypothesis you would have nothing left.

• A prediction always needs more than a single hypothesis.

• Hypotheses always come in pairs.

What is the difference between a hypothesis and a test?

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

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

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