C-GO1-SO1
By the end of this lesson you should be able to: Trace the development of the cell theory: all living things are made up of one or more cells and the materials produced by these, cells are functional units of life, and all cells come from pre-existing cells (e.g., from Aristotle to Hooke, Pasteur, Brown, and Schwann and Schleiden; recognize that there are sub-cellular particles, such as viruses and prions, which have some characteristics of living cells)
Self-check: Without looking at your notes, give one example or explanation that shows you meet C-GO1-SO1.
C-GO1
Big idea: Explain the relationship between developments in imaging technology and the current understanding of the cell
Self-check: How does today's lesson connect to C-GO1?

Hook

Maggi worms or microscope?

Pasteur and others replaced spontaneous generation.
Three tenets of cell theory.

Core explanation

We start with a real situation: Pasteur and others replaced spontaneous generation. Three tenets of cell theory. Your job is to notice evidence and ask questions before memorizing definitions.

Explain moreDeeper teaching notes — read like a tutor explaining the idea

Unit C — Cell Theory and Spontaneous Generation: Cell theory is an evidence story about how life is structured. On this slide («Maggi worms or microscope?»), the science story is: Pasteur and others replaced spontaneous generation. Three tenets of cell theory. 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 C-GO1-SO1.

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

Apply: Maggi worms or microscope?
1. State the core idea: Pasteur and others replaced spontaneous generation.
2. Link to a second point: Three tenets of cell theory.
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.
