Evidence Review

Anna Garcia Case

Review of Evidence from 1.1.1-1.1.4

Take out your notes and lets review and compare evidence so far. The questions on the next slides are timed, so make sure you have your notes out before you proceed.

This is not for a grade but it should hlep you see how your ideas compare with your classmates. Soon you will be asked to share your answers and defend why you chose them in a video that will count for a quiz grade.

Have your lab journal out and ready to go

The questions are timed. Be ready
