  2. What is the function of the microscopes base? Provides structure to the microscope.

  3. What is the first step to the scientific method? Problem

  4. Where is the diaphragm located on a microscope? Underneathe the stage

  5. What is science? Study of the natural world

  6. How do you know if something is living or not? Displays all 8 Characteristics of Life

  7. What is a qualitative observation? Observation made using your senses

  8. What is evolution? The change an organism group makes over generations.

  9. What is the function of the revolving nosepiece? Changes the power of magnification on the microscope.

  10. What is an independent variable? What is purposely changed in an experiment

  11. What is the dependent variable? The element of the experiment that depends on the independent variable.

  12. What is metabolism? The use of materials to develop energy in living things.

  13. How many eye pieces does a compound microscope have? One

  14. How many eye pieces does a stereo microscope have? 2

  15. What do you call a cell that is more than one cell? Multicellular

  16. What is a hypothesis? An educated guess on what you think will happen.

  17. What is the difference between asexual and sexual reproduction? Asexual is requires one parent, while sexual reproduction requires two parents.

  18. Which knob should only be used on high power? Fine Focus Knob

  19. What is homeostasis? The ability to maintain internal stability.

  20. How do you carry a microscope? With both hands

  21. Which objective should you always begin with? Low Power

  22. Sweating is an example of which of the 8 Characteristics of Life? Homeostasis

  23. Birds migrating is an example of which of the 8 Characteristics of Life? Responding to enviroment

  24. What is the difference between the control group and the experimental group? The control group doesn’t change anything, while the experimental group changes the independent variable.

  25. What is a quantitative observation? An observation that includes a measureable amount. (A number)
