9

Scientific method

Ways in which scientists answer questions and solve problems

10

Observation

Any use of the senses to gather information

11

Measurements

Observations that are made with tools

12

Efficiency

Compares energy output with energy input

13

Hypothesis

Possible explanation or answer to a question. A good hypothesis is testable

14

Controlled experiment

Compares the results from the control group with the results from experimental groups. The groups are the same except for one factor called a variable

15

Variable

One factor that is different than everything else in a controlled experiment

16

Data

Any pieces of information acquired through experimentation

17

What is the first step of the scientific method?

Ask a question

18

As part of the scientific method, after you ask a question what is the next step?

Form a hypothesis

19

As part of the scientific method, after you form a hypothesis what is the next step?

Test the hypothesis

20

As part of the scientific method, after you test the hypothesis what is the next step?

Analyze the results

21

As part of the scientific method, after you analyze the results what is the next step?

Draw a conclusion

22

As part of the scientific method, after you draw a conclusion what is the last step?

Communicate your results

23

Name the steps in the scientific method

1) ask a question
2) form a hypothesis
3) test the hypothesis
4) analyze the results
5) draw a conclusion
6) communicate the results

24

What are some ways to communicate the results of an investigation?

Write a scientific paper, make a presentation, or create a website

25

Why graphs and charts useful for analyzing results?

Information is easier to see and understand when is organized into charts and graphs

26

Why is boat efficiency important?

It saves resources such as fuel

27

What is the purpose of asking questions?

Helps focus the purpose of an investigation

28

What is one way to test a hypothesis?

Do a controlled experiment
