  1. 3. Variable The variable that is changed by the researcher during an experiment. It is plotted along the X-axis of a graph.
  2. 4. *Low power (10x -40x*Uses light to form a 3-D image*Used to see the surface of larger objects in more detail*Can view objects visible to the naked eye*Can view living specimens
  3. 9. the horizontal line on a graph
  4. 11. (SEM*High Power (2,000,000x)*Uses electrons to form a computer-based 3-D image*Used to see the surface of objects in detail*Samples cannot be alive
Down
  1. 1. (TEM)*Very High Power (50,000,000x)*Uses electrons to form a computer-based 2-D image*Used to see the inside of objects in detail*Shows the sample as a whole*Samples cannot be alive
  2. 2. Variable The variable that you observe or measure in an experiment that depends on the independent variable. It is plotted along the Y-axis of a graph.
  3. 5. *Medium power (1,000x)*Uses light to form a 2-D image*Used to view objects not visible to the naked eye*Objects are transparent so light can pass through
  4. 6. Kind of graph that you use if your data is in categories or groups
  5. 7. the vertical line on a graph
  6. 8. Kind of graph that you use if your data on both axes is numbers
  7. 10. Kind of graph that you use if your data can be broken down into parts of a whole
