Friday will be a review day and the Unit test will be given next Tuesday during the long block. Rubric is on next slide.
Should have about minutes to get into groups and start working on the project. We can circulate around the room to get them started. I thought we could group them first – those that want to do PSA, commercial, pamphlet. They can work in groups of 2-4 depending on what they choose.

26. Rubric
Each effect/forensic test listed and described is 7 points (84 points total)
Effects/tests that are listed but described incorrectly or not at all earn 3 points each.
