October 20 AND 21

We are creating timelines of Earth showing key developments in the origin and evolution of life. Students may use their book or online book to help with this.

Your assignment today is to learn more about the history of Life on Earth. You may choose one of four ways of doing this:

Choice Number 1 – create an illustrated timeline of event in the history of life on Earth using two sheets of plain paper taped together side by side longways, colored pencils and your textbook.



Taped papers

For the timeline:
Start with 4.6 billion years ago - page 423 – top of 424
Then p. 426
Then p. 427
Then p. 428
Then p 429-434

For each time period – you should write the date (in billion years ago, million years ago or thousands of years ago) write a short description of what Earth was looking like and what life -or conditions for life was looking like. Include any key events that occurred during the time period (for example mass extinction)

Choice Number 2 – Make a comic book about key events and types of life over the history of Earth – using pages 423, 424, 426-434. Use plain paper, colored pencils and the textbook

Choice Number 3 – Write a short story about a biologist from the future who is sent backwards through time back to the beginning of Earth to collect samples of life and the molecules that might have lead to life beginning on Earth. Include key events and dates for each time period.

Choice Number 4 – Think of your own way to show or describe the history of life on our Earth using pages 423-434 in the textbook and your online packet from Friday as a reference.
