Outcome checklist

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

D-GO4-SO1
By the end of this lesson you should be able to: Investigate and identify human actions affecting biomes that have a potential to change climate (e.g., emission of greenhouse gases, draining of wetlands, forest fires, deforestation) and critically examine the evidence that these factors play a role in climate change (e.g., global warming, rising sea level(s))
Self-check: Without looking at your notes, give one example or explanation that shows you meet D-GO4-SO1.
D-GO4-SO2
By the end of this lesson you should be able to: Identify evidence to investigate past changes in Earth's climate (e.g., ice core samples, tree ring analysis)
Self-check: Without looking at your notes, give one example or explanation that shows you meet D-GO4-SO2.
D-GO4
Big idea: Investigate and interpret the role of environmental factors on global energy transfer and climate change
Self-check: How does today's lesson connect to D-GO4?

Glossary

greenhouse gas: Key vocabulary for this lesson (greenhouse gas). Use your class notes and the slide explanations to state it in your own words — Alberta Science 10 expects you to use this term correctly in context.
paleoclimate: Key vocabulary for this lesson (paleoclimate). Use your class notes and the slide explanations to state it in your own words — Alberta Science 10 expects you to use this term correctly in context.
ice core: Key vocabulary for this lesson (ice core). Use your class notes and the slide explanations to state it in your own words — Alberta Science 10 expects you to use this term correctly in context.
dendrochronology: Key vocabulary for this lesson (dendrochronology). Use your class notes and the slide explanations to state it in your own words — Alberta Science 10 expects you to use this term correctly in context.

Hook

What changed in the last two centuries?

Industrial emissions, land clearing, wetland drainage — biomes and atmosphere respond.
Scientists ask: what is human-caused vs natural variability?

Core explanation

We start with a real situation: Industrial emissions, land clearing, wetland drainage — biomes and atmosphere respond. Scientists ask: what is human-caused vs natural variability? Your job is to notice evidence and ask questions before memorizing definitions.

Check your understanding

Unit D — Human Actions and Climate Evidence: Multiple evidence lines support human climate influence. On this slide («What changed in the last two centuries?»), the science story is: Industrial emissions, land clearing, wetland drainage — biomes and atmosphere respond. Scientists ask: what is human-caused vs natural variability? 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-GO4-SO1, D-GO4-SO2.

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

Apply: What changed in the last two centuries?
1. State the core idea: Industrial emissions, land clearing, wetland drainage — biomes and atmosphere respond.
2. Link to a second point: Scientists ask: what is human-caused vs natural variability?
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

Climate has never changed before humans — paleoclimate shows natural change, but rate and drivers differ today.
On «What changed in the last two centuries?», use the slide model and vocabulary (greenhouse gas, paleoclimate, ice core, dendrochronology) to replace this idea.
One cold winter disproves long-term warming trends.
On «What changed in the last two centuries?», use the slide model and vocabulary (greenhouse gas, paleoclimate, ice core, dendrochronology) to replace this idea.
