A-GO3-SO7
By the end of this lesson you should be able to: Predict the products of formation (synthesis) and decomposition, single and double replacement, and hydrocarbon combustion chemical reactions, when given the reactants
Self-check: Without looking at your notes, give one example or explanation that shows you meet A-GO3-SO7.
A-GO3-SO5
By the end of this lesson you should be able to: Classify and identify categories of chemical reactions; i.e., formation (synthesis), decomposition, hydrocarbon combustion, single replacement, double replacement
Self-check: Without looking at your notes, give one example or explanation that shows you meet A-GO3-SO5.
A-GO3
Big idea: Identify and classify chemical changes, and write word and balanced chemical equations for significant chemical reactions, as applications of Lavoisier's law of conservation of mass
Self-check: How does today's lesson connect to A-GO3?

Lesson walk-through

Slide 1 · Hook

Can you predict the product?

Chemists predict before they run — saves time and improves safety.

Core explanation

We start with a real situation: Chemists predict before they run — saves time and improves safety. 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 A — Predicting Products and Balancing Practice: Reaction type and solubility rules narrow what products are reasonable. On this slide («Can you predict the product?»), the science story is: Chemists predict before they run — saves time and improves safety. 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 A-GO3-SO7, A-GO3-SO5.

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

Apply: Can you predict the product?
1. State the core idea: Chemists predict before they run — saves time and improves safety.
2. Link to a second point: Chemists predict before they run — saves time and improves safety.
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

Double replacement always produces a precipitate.
On «Can you predict the product?», use the slide model and vocabulary (activity series, solubility, complete combustion) to replace this idea.

Try it yourself

Teach «Can you predict the product?» aloud in 60 seconds using two bullets and one vocabulary word from activity series.

Slide 2 · Learning intent

Outcomes

A-GO3-SO7 predict products.
Reinforce A-GO3-SO5 categories.

Core explanation

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

Outcomes — A-GO3-SO7 predict products. Reinforce A-GO3-SO5 categories. Connect this slide to 'Predicting Products and Balancing Practice' and to outcome A-GO3-SO7. 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: Outcomes
1. Restate the main idea in your own words: A-GO3-SO7 predict products.
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

Double replacement always produces a precipitate.
Use the evidence and vocabulary on this slide ('Outcomes') to replace the incorrect idea with the class model.
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 'Outcomes' to an imaginary classmate using at least two bullet ideas from the slide.

Slide 3 · Concept

Synthesis and decomposition

Combine elements or break one compound into simpler ones.
Example patterns on board.

Core explanation

Synthesis and decomposition: Combine elements or break one compound into simpler ones. Example patterns on board. 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.
