Nature of Science

6. How objects appear when observed using a hand lens or magnifying glass.
9. Type of investigation that involves collecting data on different items, or the same item under different conditions.
11. What scientists do when the evidence does not support the hypothesis.
12. Performed by scientists to collect information, or data, through observations or measurements.
13. When a measurement is close to the true size.
15. Measured with scales.
18. Type of question that cannot be answered with a basic "yes" or "no" and does not include your own belief of opinion.
20. A belief or judgement that does not have to be proved or backed up with evidence.
21. Type of investigation that involves observing and recording.
23. Objects whose volume can be found using a graduated cylinder.
25. Data that is valid and collected through repeated measurements.
27. The one thing changed in an experiment to see what effect it has on something else.
28. What scientists can see; used to form testable questions.
29. Type of investigation that involves changing a variable to see what happens.

1. A summary of the observations and data collected that explains whether a hypothesis is supported or not.
2. Done by scientists to collect background information to make a prediction of what will happen when they test their question.
3. Tool used to measure the volume of a liquid.
4. Performed by testing a variable at least three times.
5. Measured with a measuring tape, ruler, or meter stick.
7. Tool used to measure temperature.
8. Measured using stopwatches and clocks.
10. Tools that allow scientists to view tiny objects that cannot be seen with just their eyes.
14. Formed before a scientist conducts an investigation.
16. Testable prediction written as an "If...then..." statement.
17. Used by scientists when they cannot experiment on the real thing.
19. The setup to which all the others are compared in an experiment.
22. The process of reaching a conclusion about something from known facts.
24. Measured using different types of balances or a scale.
26. Means the explanation is based on evidence that is observable or measurable.
