Course Overview

Chemistry A is the first part of a sequential high school chemistry program, designed to provide students with a strong foundation in the principles of matter and its interactions. The course introduces students to atomic structure, the periodic table, chemical bonding, stoichiometry, and states of matter. Emphasis is placed on understanding both the microscopic behavior of atoms and molecules and their macroscopic effects, giving students a comprehensive view of how chemistry explains the natural world.

Key Learning Focus

• Atomic Structure: Modeling atoms and understanding subatomic particles.
• Periodic Table: Exploring trends, organization, and the properties of elements.
• Chemical Bonding: Investigating ionic, covalent, and metallic bonds and their implications in chemical compounds.
• Stoichiometry: Applying mathematical relationships to chemical reactions.
• States of Matter and Energy: Understanding the properties of solids, liquids, gases, and the role of energy in changes of state and reactions.

Instructional Approach

Instruction in Chemistry A blends teacher-led lessons with hands-on and virtual laboratory investigations. Students conduct experiments such as modeling atomic structures, analyzing chemical reactions, and investigating electrical forces between particles. Project-based activities and interdisciplinary problem-solving tasks allow students to apply theoretical concepts to real-world contexts, such as medicine, environmental science, and materials technology. Active learning strategies emphasize scientific inquiry, data analysis, and critical thinking skills.

Academic Alignment and Progression

Aligned with state and national science education standards, Chemistry A is a full-year introductory science course for grades 9–12. It is the first in a two-part sequence, followed by Chemistry B, and prepares students for advanced coursework such as AP Chemistry and college-level science classes. Completion of this course also supports pathways into scientific and technical careers across healthcare, engineering, research, and environmental sciences.

Outcomes

By the end of Chemistry A, students will:

• Demonstrate understanding of atomic structure, periodic trends, and chemical bonding.
• Apply stoichiometric principles to analyze and predict chemical reactions.
• Investigate the properties and states of matter and explain changes at both microscopic and macroscopic levels.
• Conduct laboratory experiments and interpret results using scientific methods.
• Be prepared for Chemistry B and advanced studies in chemistry and related sciences.
