Chapter 2: The Scientific Method

Question 1

Arrange the steps of the scientific method in order:

Answer 1

1. Form a question
2. Collect information
3. Form a hypothesis
4. Experiment
5. Observe
6. Collect data
7. Analyze data
8. Form a conclusion

Question 2

What happens at the step: Hypothesis?

Answer 2

Create an “If, Then, Because…” statement that predicts what will happen in an experiment

Question 3

What happens in the step: Create an Experiment?

Answer 3

Put together an experiment that will test your hypothesis and conduct it

Question 4

What happens in the step: Analyze Data?

Answer 4

Look over all of the data collected from your experiment thoroughly

Question 5

Compare and contrast: Collect Data, Analyze Data, Form a Conclusion

Answer 5

Similarities: Difference:
All contain data Perform different actions
All work with each other

Question 6

Determine what is not a characteristic of a good scientific question.

Answer 6

Opinion Based

Not Testable

Question 7

Compare: “Does Pepsi have more carbonation than Coke?” and “Does Coke taste better than Pepsi?”

Answer 7

1: Fact Based, Testable
2: Opinion Based, Not Testable

Question 8

Formulate your own scientific question.

Answer 8

Do fish swim more when it is warm outside or when it’s cold outside?

Question 9

Define what a hypothesis is.

Answer 9

An “If, Then, Because…” statement that predicts what will happen in an experiment

Question 10

Construct your own hypothesis.

Answer 10

If it is warm outside, then the fish will swim more, because their metabolism speeds up in warm weather and they need to eat.

Question 11

Develop a logical argument as to why this is or isn’t a good hypothesis: If a cricket is exposed to different temperatures then it will chirp more in times per minute, because animal activity increases in warmer temperatures.

Answer 11

No, this is not a good hypothesis, because it doesn’t specify what the different temperatures are. Their warm might be our cold.
