6-8 Time:
Two to four class periods. Teaching tips:
This module was developed for high school students, but has been used successfully with middle school students as well. Concepts:
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details. - Through billions of years of evolution, life forms have continued to diversify in a branching pattern, from single-celled ancestors to the diversity of life on Earth today.
- The patterns of life's diversity through time provide evidence of evolution. (LS4.A)
- Fossils provide evidence of past life. (LS4.A)
- There are similarities and differences among fossils and living organisms. (LS4.A)
- A hallmark of science is exposing ideas to testing. (P3, P4, P6, P7)
- Scientists test their ideas using multiple lines of evidence.
- Our knowledge of the evolution of living things is always being refined as we gather more evidence.
- Scientists use anatomical features to infer the relatedness of taxa. (LS4.A)
- Classification is based on evolutionary relationships.
