Vocabulary: Law of Superposition, Radiometric Dating, Absolute Age, Relative Dating, Relative Age, strata, paleontology, fossil, evolution Problem Statement: How do paleontologists use fossils to give relative ages to rock strata? Procedures: Before What the teacher will do: Activity: Engage - Part 1: (15 Have the students define and identify the Law of Superposition, Radiometric Dating vs. min.) Relative Dating. You may want to have the students compare Radiometric Dating vs. Relative Dating. Read and discuss reading passage with the students. “Background” Hand out , Set A in random order. Students place on the table and work in small groups to sequence the eight cards by comparing letters that are common to individual cards, and therefore, overlap. There should be lots of discussion. The first card in the sequence has on it. If the letters and represent fossils in the oldest rock layer, they are the “TC” “T” “C” oldest fossils, or the first fossils formed in the past for this sequence of rock layers. Optional: PowerPoint of this activity () & (). During What the teacher will do: Activity: Explore and Explain (45 Read Procedures for Activity 1 with the students. min.) Verify that the cards are stacked in the correct column order with the oldest rocks at the bottom. Have students complete Activity 2 with other students. Ask students to let you know when the fossil layer is correct & completed Verify responses or help them correct as needed. After What the teacher will do: Activity: Review and discuss Analysis & Conclusion questions with the students. (45 Reiterate that although you are reproducing Relative Dating, Radiometric Dating shows min.) actual numbers. Evaluate Checking individual stacks of cards. Verbal answers to the discussion questions. Students write a short paragraph explaining the Law of Superposition. Sequence information using items which overlap specific sets; students will relate sequencing to the Law of Superposition and then show how fossils can be used to give relative dates to rock layers Use the Evidence & rubric to defend your claims when writing “Claim, Reasoning” your conclusion. Extensions Students research different fossils to see where they are on the geologic time scale. Research the internet for fossil trivia, then write a question and answer game for the class. Students write a story telling the life of an animal that is facing extinction. Draw a fossil Pop-up book. Write a short definition below each picture. Students may take family field trips to a nearby fossil bed.
