Across
- 4. determining a value from the existing values in a given data set (dotted lines)
- 6. well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts.
- 8. a Manchester-based scientist
- 10. postulated the nuclear structure of the atom, discovered alpha and beta rays, and proposed the laws of radioactive decay.
- 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.
- 12. the process of drawing conclusions based on evidence and reasoning
Down
- 1. A statement about what may happen in the future.
- 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. a statement that describes an observable occurrence in nature that appears to always be true
- 5. predicting hypothetical values that fall outside a particular data set (dotted line)
- 7. an educated guess as to what will happen during your experiment
- 9. an act or instance of noticing or perceiving and the acquisition of information from a primary source.
