A Story and a Lesson About Science

(Back to Lesson)

National Science Education Standards

Inquiry

  • Scientists develop explanations using observations (evidence) and what they already know about the world.

Organisms and Their Environments

  • Humans depend on their natural and constructed environments. Humans change environments in ways that can be either beneficial or detrimental for themselves and other organisms. (K-4)
  • Changes in environments can be natural or influenced by humans. Some changes are good, some are bad, and some are neither. (K-4)

Nature of Science

  • Scientists formulate and test their explanations of nature using observation, experiments, and theoretical and mathematical models. Scientists do and have changed their ideas about nature when they encounter new experimental evidence that does not match their existing explanations. (5-8)
National Geography Standards
  • How to use maps and other geographic representations, tools, and technologies to acquire, process, and report information.
