Welcome Message:
This year, I am teaching two classes:
Chemistry, the study of matter and the changes it undergoes.
Chemistry helps us to develop an understanding of what the substances we and the world around us are made of and how they interact, from the food we eat to all the things that are a part of our daily lives.
Ecology, the study of the interactions of living things in our environment.
This class is a precursor to our Biology class and is intended to help prepare students for the Keystone Biology test.
