Part One: DON’T DO THIS PART ON MON.

Answer the following question from the discovery ed video (If watching on your own macbook your username is your full gaggle email and your password is your student ID. http://player.discoveryeducation.com/index.cfm?guidAssetId=3FF74D22-6652- 4502-B8A4-E3ED305DC497

Required Question: Why do you think it is important to measure periods of geologic time?

**If you finish watching the video at home and you answer the following questions, you will get extra credit points on your lowest grade in Science. (If you don’t have internet at home, watch the video during homeroom. Let me know if you need a note for your homeroom teacher.

Questions: (answer in a different color) 1. What two scales do geologists use to measure time?

2. How do rocks help geologists determine time periods?

3. What clues do scientists use to learn about prehistoric life?

4. What is a fossil?

5. How do fossils form?

6. What kinds of events can change Earth’s geology?

7. Describe an organism from each of the four time periods on the geologic

scale.

8. How do scientists study plants and animals that lived millions of years ago?

9. What can fossils teach us about the Earth?

10. What have scientists learned about dinosaurs by studying fossils?

Part Two:

Use the following event phrase boxes to fill in the chart on the next page. You can use your textbook Unit A Ch. 2.3 p. 61-67 for help when matching them (there is a copy of these textbook pages on my website if you need it).

You will Highlight the event phrase box you are selecting each time and copy it. Then paste each event phrase box where you think they go In the “Major Biological and Geological Events Organizer” chart on the next page of this document. You can change the color if you want to.

Make sure you pay careful attention as to whether each “event phrase” is biological or geological. Also make sure you use your textbook to place it under the correct Era

ELABORATE, Part 3 Name______Take a Journey Back in Time TASK: You work for a travel agency that has a special time machine that can take tourists back in time millions or billions of years ago. Your tourists can see plants, animals, and continents that were much different from anything they can see today. You have been assigned the task of designing a travel brochure for the travel agency.

PROCEDURE: 1. Select one of the four geologic time periods (eras) that you just made the chart for, about which you will become an expert. Complete Worksheet #1 (can be found on next page). 2. Use your textbook Unit A Ch. 2.3 p. 61-67, and internet resources to gather information about your time period (you are not allowed to use the internet for research on Mon.). You must use a minimum of 2 resources. As you study the information available, look at the animals and plants that were living during the time period as well as the surface of the earth and the climate. 3. Make a travel brochure powerpoint that gives an accurate idea of your geologic time period using text and images. Your images can be clipart, cartoons, realistic pictures, or your own drawings (in tux paint or another computer art program). Use Worksheet #2 to help you organize your information for the brochure.
