Goal 5, Objective 5.01

Goal 5

The learner will conduct investigations and utilize appropriate technologies and information systems to build an understanding of evidence of evolution in organisms and landforms.

Objective 5.01

Interpret ways in which rocks, fossils, and ice cores record Earth's geologic history and the evolution of life including:

  • Geologic Time Scale.
  • Index Fossils.
  • Law of Superposition.
  • Unconformity.
  • Evidence for climate change.
  • Extinction of species.
  • Catastrophic events.

Resources aligned to this objective

Records 1–9 of 9 displayed.

Archaeological soils
Students will determine components of a soil sample and evaluate how archaeologists use soils to interpret sites.
Format: lesson plan (grade 8 Mathematics and Science)
Stratigraphy and cross-dating
Students will use an activity sheet to interpret archaeological strata using the law of superposition and apply cross-dating to determine the age of other artifacts.
Format: lesson plan (grade 8 Science)

Lesson plans on the web

Crocs, then and now
Students investigate the geographical distributions, habitats, and other features of modern crocodilians and the so-called SuperCroc (Sarcosuchus imperator). Students will consider the things they can learn about one species by studying the other. (Learn more)

Dinosaur detectives
Students learn that discoveries about dinosaurs have a long history and that each paleontologist adds his or her work to a body of fossil evidence used to support theories about dinosaurs. Students will form groups to conduct research about a particular paleontologist and present their findings to the class. (Learn more)
