Properties of Water
Students will investigate the unique physical and chemical properties of water and their importance to life.
Key Questions
- Explain the unique properties of water, such as cohesion and adhesion.
- Analyze how water's properties make it essential for living organisms.
- Compare the solvent properties of water with other common liquids.

About This Topic
Glaciers and Climate examines the massive bodies of ice that have shaped Canada's landscape and continue to influence global climate. Students learn about the formation of glaciers and the geological features they leave behind, such as moraines and drumlins. This topic is essential for understanding Canada's physical geography and the long-term changes in Earth's climate history.
Students also investigate the role of glaciers as indicators of climate change. As glaciers melt, they affect ocean levels and salinity, which in turn impacts global weather patterns. This topic particularly benefits from hands-on, student-centered approaches where students simulate glacial movement and its erosive power on the land.
Active Learning Ideas
Simulation Game: Glacial 'Flubber' Movement
Groups use a non-Newtonian fluid (like 'flubber') to represent a glacier. They place it on a sloped tray with sand and rocks to observe how it flows and carries debris over time.
Gallery Walk: Ice Core Records
Students examine 'mock' ice cores (made of frozen layers with trapped 'bubbles' and 'dust'). They use these to reconstruct a timeline of past volcanic eruptions and temperature changes.
Think-Pair-Share: The Albedo Effect
Students discuss how white ice reflects sunlight compared to dark ocean water. They predict what happens to global temperatures as ice melts and more dark water is exposed.
Watch Out for These Misconceptions
Common MisconceptionStudents often think glaciers are just static blocks of ice.
What to Teach Instead
Teachers should emphasize that glaciers are 'rivers of ice' that flow under their own weight. Using time-lapse videos or physical simulations of flow helps students understand their dynamic nature.
Common MisconceptionMany believe that melting icebergs are the main cause of sea-level rise.
What to Teach Instead
It is important to distinguish between sea ice (which is already in the water) and land-based glaciers and ice sheets. A hands-on experiment with ice on a 'continent' versus ice in the 'ocean' clarifies this difference.

Planning templates for Science
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
rubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
