Learning Objective

Students will explore evidence and fossil record through guided practice and application.

Today's Lesson

In this lesson, we'll explore evidence: fossil record. Scientific inquiry allows us to investigate and explain natural phenomena.

Fossils are preserved remains or traces of ancient organisms. The fossil record is all fossils discovered, showing life's history. Types: body fossils (bones, shells), trace fossils (footprints, burrows), preserved organisms (amber, ice). Fossils form when organisms are buried quickly and mineralization occurs. The fossil record shows: species that once lived, how life changed over time, transitional forms (links between groups), mass extinctions. Dating methods (relative and radiometric) tell us fossil ages. Fossils are evidence for evolution!

As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.

Take notes on key points and make connections to what you've already learned in previous lessons.
