Lesson walk-through

Slide 1 · Hook

Decisions under uncertainty

Alberta winters, farming, forestry, and northern communities feel climate variability.
Science informs choices — it does not remove the need for values and perspectives.

Core explanation

We start with a real situation: Alberta winters, farming, forestry, and northern communities feel climate variability. Science informs choices — it does not remove the need for values and perspectives. 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 — Climate Science, Decisions, and Perspectives: Evidence informs choices; perspectives shape responses. On this slide («Decisions under uncertainty»), the science story is: Alberta winters, farming, forestry, and northern communities feel climate variability. Science informs choices — it does not remove the need for values and perspectives. 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-SO4, D-GO4-SO3.

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

Apply: Decisions under uncertainty
1. State the core idea: Alberta winters, farming, forestry, and northern communities feel climate variability.
2. Link to a second point: Science informs choices — it does not remove the need for values and perspectives.
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

Single weather events are not proof of climate trends — distinguish weather and climate.
On «Decisions under uncertainty», use the slide model and vocabulary (IPCC, model, perspective, stewardship) to replace this idea.
Models are not predictions with certainty — they show scenarios with stated limits.
