Science

SNC2D builds on foundational science knowledge through hands-on investigations and inquiry-based learning in biology, chemistry, physics, and earth and space science.

Students explore scientific concepts and apply them to real-world problems while developing

• Critical thinking
• Data analysis
• communication skills

This course prepares students for further study in science and fosters responsible citizenship in a scientifically literate society

Unit 1: Biology – Tissues, Organs, and Systems
Students examine the structure and function of multicellular organisms, focusing on human systems and disease prevention.
Lessons include:

• Cell Theory and Cell Specialization
• Mitosis and The Cell Cycle
• Human Organ Systems
• Disease Prevention and Health Strategies
• Ethical and Social Issues in Biology

Unit 2: Chemistry – Chemical Reactions and Properties of Matter
This unit introduces chemical bonding, naming compounds, and reaction types.
Lessons include:

• Review of Atomic Structure and Bonding
• Ionic and Molecular Compounds
• Balancing Equations and Conservation of Mass
• Types of Chemical Reactions
• Acids, Bases, and Neutralization

Unit 3: Physics – Light and Geometric Optics
Students investigate the behavior of light and how it interacts with different surfaces and materials.
Lessons include:

• The Electromagnetic Spectrum
• Reflection in Plane and Curved Mirrors
• Refraction and Lenses
• Ray Diagrams and Image Formation
• Applications in Technology

Unit 4: Earth and Space Science – Climate Change
This unit focuses on Earth’s climate system, human impact, and solutions for sustainability.
Lessons include:

• Weather vs. Climate
• Climate Systems and Global Patterns
• The Greenhouse Effect and Its Impacts
• The Role of Oceans and Landforms
• Social, Economic, and Political Dimensions of Climate Change

Assessment in SNC2D combines theoretical knowledge with practical investigations:

• 70% of the final grade is based on coursework, and assignments.
• 30% of the final grade is based on final evaluations:
  • 10% Culminating STEM project or independent investigation
  • 20% Final written exam covering all four strand

All assessments align with Ontario curriculum expectations and support the development of scientific thinking, inquiry, and real-world application.
