Chemistry

SCH4U offers students a deep understanding of chemical principles and their real-world applications.

The course emphasize-s scientific inquiry and analytical thinking through the study of atomic theory, chemical bonding, thermochemistry, equilibrium, and electrochemistry.

Students conduct investigations and solve complex problems as they prepare for postsecondary studies in science, health, or engineering fields

• 70% of the final grade is based on coursework, including:
  • Lab reports and virtual simulations
  • Stoichiometry and reaction-based calculations
  • Conceptual quizzes and problem-solving assignments
  • Inquiry projects and chemical system analyses
  • Unit tests and discussion board participation
• 30% of the final grade is based on final evaluations:
  • 10% Culminating chemical investigation or design project
  • 20% Final written exam covering theoretical and practical concepts

All assessments follow Ontario curriculum standards and are designed to develop scientific knowledge, critical thinking, and research skills for success in university-level chemistry and related fields.
