Mississippi Science L.3.4.5
The Standard
- L.3.4
- Students will demonstrate an understanding of how adaptations allow animals to satisfy life needs and respond both physically and behaviorally to their environment.
Construct scientific arguments using evidence from fossils of plants and animals that lived long ago to infer the characteristics of early environments (e.g., marine fossils on dry land, tropical plant fossils in arctic areas, or fossils of extinct organisms in any environment).

What This Standard Means
What Students Need to Do
- Students use fossils as clues to what a place was like long ago. They make a claim about the past environment and support it with details from the fossil.
What Mastery Looks Like
- Given a picture of a clam fossil found on dry land, a student says the area may once have been underwater. They explain that clams live in water today.
Common Misconceptions
- Students may think a fossil shows what the place is like now, rather than what it was like long ago. They may also claim that a single fossil tells them everything about the past environment.
How to Assess It
- Show a photo of a fish fossil found in a desert. Ask: “What might this place have been like long ago? Use the fossil as evidence.”

Ways to Teach It
Give pairs printed fossil photos and habitat cards; have them match each fossil to a possible past habitat and explain one match.
Show a clam fossil found on a dry hill and ask students to write: “What might this hill have been like long ago?”
Play a matching game with fossil and habitat cards; students earn a point only when they explain their match aloud.
Show a photo of a Kansas seashell fossil beside a Kansas map; ask students how the land may have changed.
