Session 1f: Daphnia Magna And Water Monitoring, Julie Polz, Karen Togliatti, Angela Ahrendt
Professional Learning Day
Daphnia Magna, also known as water fleas, are commonly used in water toxicity studies since they are very sensitive to chemical changes in their environment, which make them good organisms to use in water quality testing. We will be testing the effect of six environmental pollutants on the Daphnia heart rate using a microscope, and then measuring their response to each of these pollutants.

Professional Learning Day
Students understand concepts better when they have had a chance to work hands on with relevant material. Examples will be presented from my classroom where difficult concepts have been modeled into simple experiments with considerable success in enhancing student understanding. Special focus will be given to selected topics that students seem to have the most difficulty grasping. The objective is to enable students to transfer their understanding to solve complex problems with considerable ease and apply their understanding to real world scenarios on assessments. Suggestions will also be provided for implementation of various concepts into the high school classroom.
