Changing Scientific Knowledge

Science · Dinosaurs & Paleontology · meta

Evaluate competing scientific explanations about dinosaurs by weighing fossil evidence — understanding that scientific knowledge changes as new fossils are discovered and new methods of analysis are developed

Sign in to track this

What mastery looks like

  • Give an example of a scientific idea about dinosaurs that changed when new evidence was found
  • Explain that different scientists may interpret the same fossil evidence differently
  • State that the best scientific explanation is the one supported by the most evidence from multiple sources

Check your understanding

If Changing Scientific Knowledge read two different explanations for why dinosaurs went extinct, could they discuss what evidence supports each idea and why scientists sometimes change their minds?
