PowerPoint Presentation and Friday's Test

PowerPoint Presentations and Test Readiness

Most of you commented favorably on the student PowerPoint Presentations. There were some valid reservations and I would not overdo them. I am the teacher after all.
Most of you are a little unsure about the test on Friday, but you will have today and tomorrow to prepare yourself and I will not introduce any new work until after the test on Friday. Your helping hand experiment is not due until Friday 2 September.
