MS-LS4-1
The standard
Analyze and interpret data for patterns in the fossil record that document the existence, diversity, extinction, and change of life forms throughout the history of life on Earth under the assumption that natural laws operate today as in the past.
Next Generation Science Standards
What this standard means
Students need to read fossil data, rock layer diagrams, and timelines to spot patterns. They should connect older and younger layers to changes in organisms over time, including appearance, variety, extinction, and body structure complexity. They do not need to memorize eras or species names.
Mastery looks like a student using evidence from a fossil chart to explain a pattern, such as simpler body forms appearing in older layers and more complex forms appearing later. Common sticking points are treating every fossil as a direct ancestor, mixing up older and younger layers, and making claims without pointing to data.
Ways to teach it
- Give groups a set of fossil cards and rock layer strips, then have them arrange fossils by layer and identify changes in body structures.
- Ask students to write: What pattern do you see in the fossil record, and what data supports your claim?
- Show a simple fossil timeline and ask students to circle one extinction, one new appearance, and one increase in diversity.
- Compare fossil layers to a family photo album, where older photos show earlier traits and later photos show changes over time.
