Two to three class periods Concepts:
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details. - Life forms of the past were in some ways very different from living forms of today, but in other ways very similar. (LS4.A)
- Most species that once lived on Earth have gone extinct. (LS4.A)
- Fossils provide evidence of past life. (LS4.A)
- A hallmark of science is exposing ideas to testing. (P3, P4, P6, P7)
- Scientists test their ideas using multiple lines of evidence.
- Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence. (P6, NOS3)
- Scientists use multiple lines of evidence to study life over time.
- Scientists use fossils to learn about past life. (LS4.A, ESS1.C)
- Scientists use geological evidence to establish the age of fossils.
- There is a fit between the form of a trait and its function, though not always a perfect fit.
- Scientists use multiple research methods (experiments, observations, comparisons, and modeling) to collect evidence. (P2, P3, P4, NOS1)
- Scientists can test ideas about events and processes long past, very distant, and not directly observable.
