Ontario Curriculum — 2008 Revised

SCH4U Curriculum Document

Chemistry, Grade 12, University Preparation — full strand and expectations reference

Course Overview

SCH4U enables students to deepen their understanding of chemistry through the study of organic chemistry, the structure and properties of matter, energy changes and rates of reaction, equilibrium in chemical systems, and electrochemistry. Students further develop problem-solving and investigation skills as they investigate chemical processes, and refine their ability to communicate scientific information.

Prerequisite: SCH3U — Chemistry, Grade 11, University Preparation.

Fundamental Concepts

Big Ideas

Organic Chemistry: Organic compounds have predictable physical and chemical properties determined by their structures. Organic chemical reactions and their products have many applications and societal/environmental implications.
Structure & Properties: Atomic models continue to be refined to explain observed phenomena. The properties of an element depend on the structure and behaviour of its atoms.
Energy & Rates: Energy is transformed in physical and chemical changes. The rate of a chemical reaction depends on factors that can be quantitatively analyzed.
Equilibrium: Many chemical reactions in everyday life are reversible and reach a state of dynamic equilibrium.
Electrochemistry: Electrochemical reactions involve the transfer of electrons. They have practical applications and societal/environmental implications.

Achievement Chart (Growing Success, 2010)

CategoryWeightDescription
Knowledge & Understanding25%Recall facts, terminology, concepts; comprehension of relationships
Thinking & Investigation25%Planning, processing, problem-solving, critical/creative thinking
Communication25%Expression and organization of ideas; use of conventions, vocabulary, terminology; communication for different audiences
Application25%Application of knowledge and skills in familiar contexts; transfer to new contexts; making connections (STSE)

70/30 Policy

The final mark consists of two components: 70% term mark (based on assessment OF learning throughout the course, with emphasis on the most consistent or most recent evidence) and 30% summative (a final examination, performance task, or combination thereof administered near the end of the course). Both components reflect all four achievement-chart categories with equal weighting (K/U 25%, T 25%, C 25%, A 25%).
