      TEKS 4.12C: Fossil Evidence of Past Environments

      • Fossils and Past Environments

        About this lesson

        Learning Target: I can identify fossils and use them to describe changes to the environment.

        Focuses On:

        • Types of fossils
        • Fossil layers
        • Common Texas Fossils

        Builds On:

        3.12D:

        identify fossils as evidence of past living organisms and environments, including common Texas fossils

        Next Level:

        B.9B:

        examine scientific explanations for varying rates of change such as gradualism, abrupt appearance, and stasis in the fossil record

        Read More:

        This lesson is designed to support student understanding of how fossil evidence is used to interpret past environments.

        The lesson begins with a review of fossil types, such as terrestrial and aquatic, and analyzes how their positions within rock strata indicate environmental changes over time. It then explores common Texas fossils, using real locations and scenarios to discuss how these areas have transformed based on the fossil record.

        This foundational knowledge prepares students for standard 8.9B, where they will analyze the fossil record in greater depth.
