Earth Clock -Timeline From Past To Present

Is Earth history fun? Yes! This lesson reaches back to the beginning of earth and presents its entire life, up to now, on the scale of a 24-hour clock. Now that’s serious fun (at least for us science people).

Handout, Notes, and PPT


update- Here’s a little student handout I put together to simplify things and save a little time in the lesson. Now you have the option of students starting with a blank sheet of paper, or with this handout.
