Geologic+Time+Scale+Activity

__ Geologic Time Scale __ 1. In this activity you will start by constructing a timeline of the Paleozoic, Mesozoic, and Cenozoic Eras in pairs. 2. Tape two half sheets of blank paper together so they are 55 cm long. 3. (Scale: 1cm = 10 million years) Copy this in the bottom left corner of your timeline 4. Write “Today” parallel to the right edge of your paper and this will represent the current time. 5. All measurements will be made from the right side of your timeline, in other words the present time. 6. Write the events from the table at the correct measurement on your time line. (Start at the top of the table) 7. Put the Permian extinction on your timeline. Remember, this extinction ends the Paleozoic Era. 8. Put the extinction of the dinosaurs on your timeline. Helpful-Hint: What Era was ended by this extinction? 9. Work the students at the table touching yours. Tape a string 4.6 meters long cross the top edges of the tables. 10. Measure and tape tags of paper to this string to mark the rest of the events on the Events-table handed out. 11. Hold your paper timeline at the right end of your string timeline and view the whole “Geologic Time Scale.” 12. Write the questions (50%) and answer(25%) them. Title this assignment and add it to your Science Notebook.
