Nature of Science

8. the factor that is intentionally changed or manipulated by the scientist to see how it affects something else
11. repeating a scientific experiment or study to see if the same results can be obtained
12. the act of gathering information using your senses or tools to study something closely and carefully
15. a systematic way for scientists (and anyone!) to investigate the world around them. It involves asking questions, forming educated guesses (hypotheses), testing those guesses through experiments, and then drawing conclusions based on the results.
16. a statement about what is expected to happen in a future event or situation, based on evidence or observations
17. the factor that is measured or observed in an experiment to see if it's affected by changes to the independent variable
18. a globally recognized standard system of measurement used in science and most countries

1. information gathered through direct observation or experimentation that supports a scientific explanation
2. the factor that a scientist intentionally changes in an experiment to see how it affects something else
3. a test where only one factor (variable) is changed at a time, while all other conditions are kept the same
4. a standard of comparison in an experiment
5. conducting the same experiment or observation multiple times under the same conditions to check the reliability of the results
6. the factor that is measured or observed to see if it is affected by changes in another variable
7. those that can be measured and expressed with numbers
9. describe the characteristics or qualities of something using words, rather than numbers
10. a testable statement that proposes a possible explanation for a scientific question or observation
13. a conclusion or explanation reached based on observations and prior knowledge
14. factor or condition in an experiment that is kept the same throughout the entire experiment
