  1. 5. observations-Qualitative observations use your senses to observe the results. (Sight, smell, touch, taste and hear.) Quantitative observations are made with instruments such as rulers, balances, graduated cylinders, beakers, and thermometers. These results are measurable
  2. 6. curved upper surface of a liquid in a tube
  3. 8. the process of a liquid changing into a gas. An example of evaporation is water turning into steam.
  4. 10. Variable-a variable (often denoted by y ) whose value depends on that of another
  5. 13. test-Conducting a fair test is one of the most important ingredients of doing good, scientifically valuable experiments. To insure that your experiment is a fair test, you must change only one factor at a time while keeping all other conditions the same. Scientists call the changing factors in an experiment variables.
  6. 15. Variable-a variable (often denoted by x ) whose variation does not depend on that of another.
  7. 16. smallest particle of a chemical element that can exist
  8. 17. properties-A physical property is any property that is measurable, whose value describes a state of a physical system. The changes in the physical properties of a system can be used to describe its transformations or evolutions between its momentary states
  9. 18. is a chemical process where a solid turns into a gas without going through a liquid stage. An example of sublimiation is when ice cubes shrink in the freezer.
  10. 19. action of deposing someone, especially a monarch

  1. 1. or become liquefied by heating.
  2. 2. observations-relating to, measuring, or measured by the quantity of something rather than its quality.
  3. 3. supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation
  4. 4. a substance or object) capable of being decomposed by bacteria or other living organisms and thereby avoiding pollution
  5. 7. substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy
  6. 9. which collects as droplets on a cold surface when humid air is in contact with it
  7. 11. scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.
  8. 12. element, feature, or factor that is liable to vary or change.
  9. 14. or be joined securely to something else, especially by means of an adhesive substance, heat, or pressure.
