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.

Lesson walk-through

Slide 1 · 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?

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.

Try it yourself

Teach «Opening: Biomes as Open Systems» aloud in 60 seconds using two bullets and one vocabulary word from today’s list.

Slide 2 · Learning intent

Learning intentions (Alberta POS)

General outcomes: D-GO3.
Specific: D-GO3-SO1

Core explanation

This slide lists what you are learning today (Learning intentions (Alberta POS)). Your teacher will map each bullet to the Alberta Program of Studies—these are the ideas your class must cover, not extra trivia.

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

Learning intentions (Alberta POS) — General outcomes: D-GO3. Specific: D-GO3-SO1 Connect this slide to 'Biomes as Open Systems' and to outcome D-GO3-SO1. If anything is unclear, write a specific question for your teacher — vague 'I don't get it' is harder to help.

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

Think through: Learning intentions (Alberta POS)
1. Restate the main idea in your own words: General outcomes: D-GO3.
2. List one observation or fact that supports it.
3. State one question you still have.
Why this works: Science 10 rewards clear reasoning, not only recall.

Common mistakes to avoid

Treating outcome codes as labels to ignore.
Paraphrase each outcome in everyday language — that paraphrase is what you should be able to explain on your own.

Try it yourself

Explain 'Learning intentions (Alberta POS)' to an imaginary classmate using at least two bullet ideas from the slide.

Slide 3 · Concept

Biome inputs and outputs

Energy and matter cross biome boundaries.

Core explanation

Biome inputs and outputs: Energy and matter cross biome boundaries. In class your teacher will expand on this; use these notes to recall the main science ideas.

Check your understanding

In your notebook, restate the main idea in one sentence without looking.
Name one new vocabulary word and define it in your own words.

Slide 4 · Guided practice

Guided practice

Apply ideas in pairs; justify with POS vocabulary.

Core explanation

Guided practice: Apply ideas in pairs; justify with POS vocabulary. In class your teacher will expand on this; use these notes to recall the main science ideas.

Check your understanding

Try one practice item again without help—did your method change?
