This academic program is designed to study matter and its changes. The program emphasizes the context of science by considering the interrelationships among science, technology and society. Students, through the study of Chemistry 20-30, are given an opportunity to explore and understand the natural world and to become aware of the profound influence of chemistry on their lives. The four topics covered are: The Diversity of Matter and Chemical Bonding, Forms of Matter: Gases, Matter as Solutions, Acids and Bases and Quantitative Relationships in Chemical Changes. Prerequisite: Science 10: 50% (It is recommended that students taking Chem 20 have completed Math 10 Pure or Math 10 Combined). Students without the prerequisite must withdraw from class with no refund if they are under 20 years of age as of September 1 of the current school year.
