“Commit and Toss” thinking activity- Teacher asks the question “If Geologic time were just 24 hours, when would the first animals
appear? When would plants appear? When would man appear?” Students write their answers anonymously and then fold and “toss”
their papers into a basket. Students are called on to pick a paper from the basket and then read aloud. (pre-assessment)

to the “timeline” at the appropriate place that they would appear. Add the names of the eras and periods to a Word Wall.
