Outcome checklist

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

B-GO2-SO13
By the end of this lesson you should be able to: Investigate and analyze one-dimensional scalar motion and work done on an object or system, using algebraic and graphical techniques (e.g., the relationships among distance, time and velocity)
Self-check: Without looking at your notes, give one example or explanation that shows you meet B-GO2-SO13.
B-GO2
Big idea: Explain and apply concepts used in theoretical and practical measures of energy in mechanical systems
Self-check: How does today's lesson connect to B-GO2?

Where this shows up later

Unit B — Thermodynamics: Heat and work are energy transfers.

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.

Roller coasters without leaving the desk

Track height and speed — energy transforms.
Use algebra for d, t, v relationships.

Core explanation

We start with a real situation: Track height and speed — energy transforms. Use algebra for d, t, v relationships. 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 B — Mechanical Energy Transformations: Mechanical systems swap kinetic and potential energy — friction steals some as heat. On this slide («Roller coasters without leaving the desk»), the science story is: Track height and speed — energy transforms. Use algebra for d, t, v relationships. 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 B-GO2-SO13.

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

Apply: Roller coasters without leaving the desk
1. State the core idea: Track height and speed — energy transforms.
2. Link to a second point: Use algebra for d, t, v relationships.
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.
