"The History of Everything"
lesson resides off-site, over which we have no control. As of
this date (6-23-09), the link seems to be working. If you find
that it isn't, please let us know (contact the webmaster).
In the meantime, or as an alternative,
take a look at our "Time Machine" lesson. This provides
instructions for making a classroom-sized scaled timeline that
deeply engages your students. For some other very effective ideas
along this line, go to the Extensions & Variations
of that lesson, especially item #6 for two engaging activities
from the UC Museum of Paleontology that effectively teach geological
time. And #3 "Patterns in Time" is a recent
addition that helps students get a realistic sense of the vastness
of geological time as it relates to their own lifetime. "Other
Resources" will give you additional materials and ideas.
