Science overview

  1. 1. Introduction to Science
  2. 2. What is ”Science”? Science… is made up of mistakes, but they are mistakes which it is useful to make, because they lead little by little to the truth.” –Jules Vern
  3. 3. What is ”Science” Science is not a ‘thing’, but a way of thinking. Focus of science is the natural world Can be used to understand anything that is Observable Observable: able to be experienced using the senses Science changes over time to give the best explanation possible
  4. 4. Observations The noticing and describing of events or processes. Observations rely on our senses, or on scientific instruments which enhance our senses. Observations can be: Qualitative: use adjectives and descriptions Quantitative: use measurements and numbers
  5. 5. Hypothesis A possible explanation for a set of observations, or a possible answer to a scientific question. A good hypothesis should offer predictions that are testable
  6. 6. Model A representation of an idea, object, system, or process which is used to explain something that cannot be experienced directly. Similar to a hypothesis. Types of model include conceptual (ideas), mathematical, computer, physical.
  7. 7. Prediction A guess, based on observations, hypothesis, or theory, which is observable and testable.
  8. 8. Theory A well tested explanation that unifies a broad range of observations and hypotheses, and enables scientists to make accurate and testable predictions about new situations. Theories will change to incorporate and explain new observations, or will be replaced by better theories Ex: Theory of Gravity, Theory of Relativity, Germ Theory, Theory of Evolution, Molecular Theory, Theory of Plate Tectonics
  9. 9. Observations Hypothesese Models Predictions Theory
