Science skills: Measuring results

  • Scientific ideas are not accepted until there is evidence to back them up.
    • Theories, theorems and experimental results are published in scientific journals. These undergo peer review by the scientific community before they are accepted.
    • Scientists will also repeat experiments described in journals to confirm their results are valid.
    • Some scientific ideas considered correct today were not initially accepted until decades after they were first published, such as Darwin’s theory of evolution.
  • Currently accepted scientific theories and models are the ones that best fit the current evidence and knowledge of the universe. They may be disproven in future.
  • Scientific ideas that are reported in popular media before verification and peer review can lead to negative opinions of science.
