When an explanation correctly predicts an event, confidence in the explanation as science knowledge is increased


Predicting a solar or lunar eclipse can be used to support the explanation (theory) that the Earth orbits the Sun.

Teacher reflection

  • Why does a correct prediction increase confidence in an explanation?
  • If an explanation doesn’t correctly predict an event, is the explanation necessarily wrong? Why or why not?
  • Does a correct prediction need to support an explanation for the explanation to be accepted? Why or why not?
  • Do scientists always have to test their explanations by using predictions? Why or why not?
