2. Analyze  Study a topic closely, break a topic down into smaller parts.

3. Bar Graph  The pictorial display of a set of data using bars to indicate the value, amount or size of the dependent variable for each level of the independent variable tested. Usually the taller the bar, the greater the value of the dependent variable.

4. Beaker  Tool used to measure volume

5. Conclusion  A summary of what is learned from an experiment.  The last section of a report of an experiment, it states the purpose, major findings, hypothesis, and recommendations for further study.

6. Constant  All of the factors or conditions that must be kept the same in an experiment.

7. Control Group  The group treated normal to which the experimental group is compared. Factors that are fixed in an experiment.

8. Data  Recorded information from experiments

9. Data Table  A chart to organize and display the data collected in an experiment.

10. Degrees Celsius  The SI unit of measurement for temperature. ⁰C

11. Dependent Variable  The dependent variable is what you measure or observe to obtain your results.  Is found on the y-axis of a graph and in the left column of a data collection table.

12. Evidence  Data found using a scientific process.

13. Experiment  A test of a hypothesis. It determines if purposely changing the independent variable does indeed change the dependent variable.

14. Experimental Group  The group exposed to all conditions of the experiment. The group being tested.

15. Experimental Procedure  Detailed, step-by-step directions for conducting a science experiment which allow duplication.

16. Graduated Cylinder  A narrow container used to measure the volume of liquids

17. Gram (g)  The SI unit of measurement for mass.

18. Hypothesis  A testable explanation for an observation or scientific problem. Written as an IF, THEN statement.

19. Independent Variable  The one factor or condition that is changed by the experimenter  Found on the x-axis of a graph.  Is recorded in the left column of a data table.

20. Interpret  To determine the patterns and trends from scientific data or information.

21. Intervals  The equal size values represented by the equal spaces marked along the axis of a graph.

22. Line Graph  A pictorial display of data that can be drawn when the data for both variables are continuous data. The line in a line graph shows the relationship between the independent and dependent variables.

23. Liter (L)  The SI unit of measurement for volume.

24. Mass  A measure of the amount of matter in an object.

25. Mean (Average)  One of the measures of central tendency (average); the sum of numbers in a set of data divided by the number of pieces of data.

26. Measurable  Able to be measured

27. Meter (m)  The SI base unit for length and distance.

28. Meter stick  The tool used to measure distance or length.

29. Model  A pattern, plan, representation, or description designed to show the structure or workings of an object, system or concept.

30. Observation  The use of the sense to describe the natural world.

31. Qualitative Data/Observations  Observations involving quality or kind, recorded characteristic that cannot be expressed in numbers. Color Shape

32. Quantitative Data/Observations  Observations that involve a number in the form of an amount or measurement.

33. Repeated Trials  Repeating measurements several times. The more measurements made the more reliable the results.

34. SI System of Measurement  The International System of Units is the modern form of the metric system and is generally a system of units of measurement devised around seven base units and the convenience of the number ten. It is the world's most widely used system of measurement, both in everyday commerce and in science.

35. Spring Scale  Tool used to measure force or weight

36. Stopwatch  Tool used to measure time.

37. Testable Question  A question that is answered through a scientific investigation.

38. Thermometer  Tool used to measure temperature.

39. Triple Beam Balance  Tool used to measure mass.

40. Untestable  A question that cannot be answered through a scientific investigation.

41. Validity  The extent to which a test measures what it claims to measure.

42. Variable  Factor that can change in an experiment

43. Volume  The amount of space occupied by an object

44. Weight  The force of gravity exerted on an object’s mass.

45. x-Axis  The line along the bottom of a graph on which the scale for the independent variable is placed.

46. y - Axis  The vertical line drawn on the left side of a graph on which the scale for the dependent variable is placed.
