  1. 4. determining a value from the existing values in a given data set (dotted lines)
  2. 6. well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts.
  3. 8. a Manchester-based scientist
  4. 10. postulated the nuclear structure of the atom, discovered alpha and beta rays, and proposed the laws of radioactive decay.
  5. 11. British physicists who first theorized and offered experimental evidence that the atom is a divisible entity rather than the basic unit of matter, as was widely believed at the time.
  6. 12. the process of drawing conclusions based on evidence and reasoning

  1. 1. A statement about what may happen in the future.
  2. 2. proposed a theory for the hydrogen atom, based on quantum theory that some physical quantities only take discrete values. Electrons move around a nucleus, but only in prescribed orbits, and If electrons jump to a lower-energy orbit, the difference is sent out as radiation.
  3. 3. a statement that describes an observable occurrence in nature that appears to always be true
  4. 5. predicting hypothetical values that fall outside a particular data set (dotted line)
  5. 7. an educated guess as to what will happen during your experiment
  6. 9. an act or instance of noticing or perceiving and the acquisition of information from a primary source.
