Discovery Lab: Making a Geologic Time Line

Materials: Tape, sheets of printer paper, meter sticks, scissors, glue, colors, image packet, Ipads/smartphones/laptops

Procedure

Setting up the timeline:

1. Arrange sheets of printer paper in a landscape orientation and line them up end to end, forming a 5 meter-long

2. Using clear transparent tape, tape the paper together so that there is 5 meters of paper

from end to end.

3. Using a meter stick, draw a line through across the middle of the paper from left to

right.

4. In the top left corner, make a scale. Label the scale: 1 cm = 10 million years

5. Starting on the left side of the paper, measure 5 cm, to the right on the line, and make

a vertical mark. Label this mark with the word “Today”.

6. From this mark, measure 1 meter to the right on this line and make a vertical mark.

Label this mark “1 billion years”. Measure and mark each meter after that up to 4

meters or 4 billion years from today.

7. Now, measure 60 cm to make the total length of the time line 4.6 meters. Mark and

label this distance 4.6 billion years (The Beginning of Time).

Marking events on the timeline:

8. Label the year and name of each eon, era, and period on your geologic time scale.

Using the scale 1 cm = 10 million years, measure the distance to each era from Today.

9. Using both your image packet and the list below as guides, measure, mark, and label the major events of each era on your geologic time scale. (If you don’t know when an event occurred, research it using reputable sources on the internet.)

-Greatest known extinction event

-Oldest known fossil

-First marine reptiles   (mosasaur and plesiosaur)

-First Coal-forming forest

-Pangaea begins to break

-First land animals

-First forests

-Formation of the Western Interior Seaway

Annotating Events:

10. Color and cut out each of the images in the image packet.

11. Paste them onto the geologic time scale .

12. Label all the letter images, using the space allowed on the timeline

13. Annotate all images and events with additional information provided in the image packet as well as researched on your own. In your annotation include:

   1. Crucial information

2. Why it is important to know

Geologic Time Scale Questionnaire: What Do You Know? (1-10)

Procedure: On a sheet of paper, write out your answers to the best of your knowledge. Give yourself a lot of space, because you will return to this worksheet after every lab day and update your answers. Write in a different color of ink for each day and create a key for which color was used on which day.

1. How much older is Earth than you?

2. How would you help a kindergarten student understand the age of the Earth?

3. How do scientists determine when an eon, era, or period begins and ends?

4. When did the greatest extinction event occur on Earth? How?

5. What triggered the beginning of the Cenozoic era?

6. How did photosynthesis change Earth’s atmosphere? Why was this one of the most significant events in Earth’s history?

7. What evolutionary adaptation allowed for life on land?

8. In your opinion, what was the most crucial geological or biological event for the evolution of humans?

9. What evidence have scientists used to answer these kinds of questions?

10. Why is it important for scientists (and us) to study the history of the Earth?

Technology #3

1. Technology- Research the fishing technologies of the following groups

Include in your description in addition to the other questions we normally use.

1. the tools they used and how to make them.
2. The food preservation/ cooking techniques.
