Celebrating our ChemEd X PAEMST Finalists

It may come as no surprise that three of our very own lead contributors have been named as  Finalists for the 2021 Presidential Awards for Excellent in Mathematics and Science Teaching (PAEMST) at the secondary level in their states. We would like to recognize them along with all of the amazing math and science teachers across the country that have earned this honor.
