I will be presenting one of my lab activities at a conference for the Maryland Association of Science Teachers (MAST). My presentation will be on Saturday, October 18 from 9:30-10:30 AM. In addition to presenting, I will also be at a table where I will be selling copies of the newest edition of the lab manual. Since this table space will be much more than I need, I will use most of this space to do demonstrations that will hopefully get people's attention.
