Geology Study Guide

Study Guide How does an idea turn to a hypothesis and then to a theory? In scientific reasoning, a hypothesis is constructed before any applicable research has been done. A theory, on the other hand, is supported by evidence: it’s a principle formed as an attempt to explain things that have already been substantiated by data. (Hypothesis- An idea that has been tested many, many times, pretty much works, still has some issues that might be worked out.) (Theory- The BEST explanation of the facts so far. Predictable. Testable. Most scientist agree that it is probably right.) What is a scientific fact? An objective and verifiable observation, in contrast with a hypothesis or theory, which is intended to explain or interpret facts.(An observation)  What is the difference between a theory and a law?

  1. How does an idea turn to a hypothesis and then to a theory?
  • In scientific reasoning, a hypothesis is constructed before any applicable research has been done. A theory, on the other hand, is supported by evidence: it’s a principle formed as an attempt to explain things that have already been substantiated by data. (Hypothesis- An idea that has been tested many, many times, pretty much works, still has some issues that might be worked out.) (Theory- The BEST explanation of the facts so far. Predictable. Testable. Most scientist agree that it is probably right.)
  1. What is a scientific fact?
  • An objective and verifiable observation, in contrast with a hypothesis or theory, which is intended to explain or interpret facts.(An observation) 
  1. What is the difference between a theory and a law?
  • A law is a description of an observed phenomenon in the natural world that hold true every time it is tested. It doesn’t explain why something is true; it just states that it is true. A theory, on the other hand, explains observations that are gathered during the scientific process.
  1. Describe the Big Bang.
  • the rapid expansion of matter from a state of extremely high density and temperature that according to current cosmological theories marked the origin of the universe.
  1. What evidence is there of the Big Bang?
