Ch. 1 - Central Science

2. a type of scientific investigation that seeks to gain knowledge for the sake of knowledge itself
4. in an experiment, the standard that is used for comparison
6. study of matter and the changes it undergoes
7. amount of mass per unit volume; physical property
9. a measure that reflects the amount of matter anything that has a mass and takes up space
11. The SI base unit of volume
12. information describing color, odor, shape, or some other physical characteristic
15. matter that has a definite composition
16. a tentative, testable statement or prediction about what has been observed.
18. an explanation supported by many experiments; can be used to make predictions that are proven true
20. The SI base unit of Distance
21. a visual display of data
22. a type of scientific investigation that is undertaken to solve a specific problem
25. The SI base unit of Temperature
26. in an experiment, the variable that the experimenter plans to change
27. numerical information (Ex. how much, how big, how tall, or how fast)

1. in an experiment, the variable whose value depends on the independent variable
3. a systematic approach to problem solving that uses conversion factors to move from one unit to another
5. The SI base unit of mass
8. a systematic approach used in scientific study; an organized process used by scientists to do research and to verify the work of others
10. how close a measured value is to an accepted value
13. describes a relationship in nature that is supported by many experiments
14. anything that has mass and takes up space
17. how close a series of measurements are to eachother
19. a set of controlled observations that test the hypothesis
23. a visual, verbal, and/or mathematical explanation of data collected from many experiments
24. a measure of an amount of matter with respect to earth's gravitational pull
