About SCH4U – Grade 12 Chemistry
SCH4U is Ontario’s Grade 12 university preparation Chemistry course. It builds on the scientific knowledge and investigation skills developed in Grade 11 Chemistry and introduces more advanced chemical concepts and applications.
The course explores the structure and properties of matter, organic compounds, chemical reactions, energy changes, equilibrium, and electrochemical processes. Students examine how these concepts explain chemical behaviour and contribute to scientific and technological developments.
Students develop analytical, mathematical, and scientific communication skills through chemical calculations, investigations, data interpretation, and problem-solving activities. The course also examines the effects of chemical processes and technologies on society, human health, and the environment.
Successful completion of SCH4U earns one credit toward the Ontario Secondary School Diploma (OSSD) and can support preparation for university programs in chemistry, engineering, health sciences, and related fields, subject to individual admission requirements.
What Will Students Learn in SCH4U?
By the end of the course, students will have opportunities to:
Explain the structure, properties, and naming conventions of organic compounds.
Investigate common organic reactions and their applications in everyday life and industry.
Analyse atomic structure, chemical bonding, molecular geometry, and intermolecular forces.
Explain how molecular structure influences the physical and chemical properties of substances.
Investigate energy changes in chemical reactions using thermochemical principles and calculations.
Analyse factors that influence chemical reaction rates and reaction mechanisms.
Explain dynamic equilibrium and predict how changes in conditions affect chemical systems.
Apply equilibrium concepts to chemical calculations and real-world processes.
Investigate oxidation-reduction reactions and the operation of electrochemical cells.
Examine applications of electrochemistry, including batteries, corrosion, and industrial processes.
Apply scientific investigation skills to chemical problems, experimental data, and chemical calculations.
Evaluate the environmental, technological, and societal implications of chemical processes.
SCH4U Course Content: Ontario Curriculum Strands
SCH4U follows The Ontario Curriculum, Grades 11 and 12: Science, 2008 (Revised). The course includes five subject-specific strands, with scientific investigation skills and career exploration integrated throughout the learning expectations.
Strand A: Organic Chemistry
Students investigate the structure, properties, and reactions of organic compounds, including hydrocarbons and compounds containing functional groups.
They explore organic nomenclature, isomerism, common reaction types, and the applications of organic chemistry in industry, medicine, and everyday life.
Strand B: Structure and Properties of Matter
Students examine atomic structure, chemical bonding, molecular geometry, and the forces that influence the properties of substances.
They investigate how models of matter explain chemical behaviour and how molecular structure affects physical and chemical properties.
Strand C: Energy Changes and Rates of Reaction
Students explore the energy changes associated with chemical reactions and the factors that influence reaction rates.
They apply thermochemical principles, energy diagrams, and quantitative calculations to analyse reaction enthalpy, activation energy, and reaction kinetics.
Strand D: Chemical Systems and Equilibrium
Students investigate reversible reactions and the conditions under which chemical systems reach dynamic equilibrium.
They explore equilibrium constants, Le Châtelier’s principle, acid-base equilibrium, and the application of equilibrium concepts to chemical processes.
Strand E: Electrochemistry
Students examine oxidation-reduction reactions and the transfer of electrons in chemical systems.
They investigate electrochemical cells, standard electrode potentials, electrolysis, and applications such as batteries, corrosion prevention, and industrial electrochemical processes.
Assessment and Evaluation in SCH4U
Assessment and evaluation in SCH4U are designed to measure students’ achievement of the knowledge and skills outlined in The Ontario Curriculum, Grades 11 and 12: Science, 2008 (Revised).
Students demonstrate their learning through chemistry assignments, problem-solving exercises, scientific investigations, laboratory-related activities, tests, research tasks, and other assessments aligned with the course expectations.
Evaluation considers four categories of achievement:
Knowledge and Understanding: Demonstrating knowledge of chemical concepts, principles, terminology, and relationships.
Thinking and Investigation: Applying scientific inquiry, critical thinking, experimental planning, data analysis, and problem-solving skills.
Communication: Communicating scientific information using appropriate terminology, chemical equations, calculations, diagrams, and written explanations.
Application: Applying chemistry concepts and scientific skills to practical situations, technological developments, and environmental issues.

Final Examination and Proctoring
Ontario International School (OIS) administers its final examinations through the school’s established examination and proctoring procedures.
Students completing SCH4U must write a final examination under the supervision of an approved, impartial proctor.
Students are responsible for arranging a qualified proctor and submitting the Exam Proctoring Application Form at least three weeks before their intended examination date. All proctors must be approved by the OIS principal.
For proctor eligibility requirements, application instructions, and examination arrangements, students should review the school’s Final Examination and Proctoring Procedures page.
Learning Accommodations
Ontario International School (OIS) recognizes that students have different learning needs. Students who require learning accommodations are encouraged to contact OIS to discuss their individual circumstances and available academic support options.
Where applicable, accommodations are considered in accordance with Ontario Ministry of Education policies and the student’s documented learning needs.
