Today was our first day back from vacation and we finally were able to do our lab, A Mouthful of Minerals. After reviewing our notes from before Camp Kieve, we proceeded to test three toothpastes to see which worked best to remove marker from a ceramic tile. (The marker mimicked plaque while the tile stood in as a model for our teeth.)
Tomorrow we will discuss our results and students will have a chance to write up their lab reports as a group or individually. All lab reports will be due on Friday.
Students missing today will have a lab make-up day after school in the near future.
