Outcome checklist

Alberta Program of Studies — tick each row when you can explain it without the slide.

D-GO3-SO1
By the end of this lesson you should be able to: Describe a biome as an open system in terms of input and output of energy and matter and exchanges at its boundaries (e.g., compare and contrast cells and biomes as open systems)
Self-check: Without looking at your notes, give one example or explanation that shows you meet D-GO3-SO1.
D-GO3
Big idea: Relate climate to the characteristics of the world's major biomes, and compare biomes in different regions of the world
Self-check: How does today's lesson connect to D-GO3?

Where this shows up later

Unit D — Greenhouse effect: Biomes exchange matter and energy openly.

Lab and demo watch-outs

Classroom safety
Follow school rules for equipment, goggles, and fire safety even during thought experiments.
Any time hands-on work is suggested.

Hook

Opening: Biomes as Open Systems

Introduce biomes-as-open-systems.

Core explanation

We start with a real situation: Introduce biomes-as-open-systems. Your job is to notice evidence and ask questions before memorizing definitions.

Check your understanding

Can you connect this slide to something we learned earlier today?

Explain moreDeeper teaching notes — read like a tutor explaining the idea

Unit D — Biomes as Open Systems: Biomes exchange matter and energy — human use changes those flows. On this slide («Opening: Biomes as Open Systems»), the science story is: Introduce biomes-as-open-systems. Read like a tutor: connect each bullet to evidence or a model, not memorized wording. Alberta Science 10 expects you to explain ideas in class discussions and written work — this slide supports outcomes D-GO3-SO1.

Worked example(s)Step-by-step reasoning, not just answers

Apply: Opening: Biomes as Open Systems
1. State the core idea: Introduce biomes-as-open-systems.
2. Link to a second point: Introduce biomes-as-open-systems.
3. Give one Alberta or daily-life example that fits both ideas.
4. Check your example against the slide — would your teacher agree?
Why this works: Application proves understanding beyond repeating bullets.

Common mistakes to avoid

Repeating the slide without understanding.
Cover the bullets and explain the idea using a new example.
