COURSE DESCRIPTION
Chemistry is an experimental science combining study and investigation. Chemistry is necessary for understanding many others related courses including physics, biology and higher-level electives. This course is necessary for higher education in both biological sciences and environmental science, and will serve as preparation fro employment. The course will fill core requirements listed in the outline of topics and provide optional resources for further chemistry such as analytical, organic, engineering and food related chemistry.
