1. Timeline of Planet Earth

2. 1 Million 1, 000,000 A million seconds = 12 days.
A million minutes = 1 year, 329 days, 10 hours and 40 minutes.
A million hours ago it was 1885
It would take 23 days without sleeping to count to a million.
See video on You Tube or United Streaming explaining a million and a billion….

3. 1 Billion 1,000,000,000 A billion seconds = 31 years.
A billion hours ago homo sapiens had not evolved.
A billion kids on each others shoulders would stretch past the moon.
If you counted from one to one billion, you would be counting for 95 years.
One thousand million, is a billion.

4. The Earth is 4.6 Billion years old.

5. Directions Organize into groups of 2-4 people.
Gather a meter stick and roll of adding machine tape.
Measure carefully 5 meters of adding machine tape from the roll and cut it off.
Measure 20 cm from one end, draw a line across and label the line “Today”.
Add group member names and hour to that end of the roll, closest to the far end.

6. Directions
Measure and mark your timeline in 1 meter increments/1 billion year increments ~ starting at the today line.
Label each 1 meter as 1 billion years. (Be precise.)
Scale:
1 millimeter =1 million years.
1 meter = 1 billion years.
End of day 1

7. Time Divisions Earth Time is arranged into Eon’s, Era’s & Periods.
Please measure and label them on your timeline.
Color each Period a different color, and each Era a different color as well. Skip the color coding of the Eon’s. Remember that an Era crosses over several periods so draw them in with pencil before coloring.
Day 2

8. Adding Events
Now that your Eras & Periods are labeled and colored, begin adding events into your timeline. Attach the pieces somehow to the timeline.
Attach to the front?
Attach as flip in from the sides with an x showing specifically where it belongs.
Measure from the today line, because every thing is measured in m.y.a. or millions of years ago.
Remember Your
Scale:
Each millimeter =1 million years.
Each meter = 1 billion years.
