BIG IDEA
Understand the idea before memorising a rule.
Cells and organisation is part of biology. At Grade 7, the goal is to connect this topic to a clear method, relevant evidence and a final check. You will apply that idea to a real biology question at this grade level.
YOU WILL LEARN TO
- Explain the key ideas in cells and organisation using accurate science vocabulary.
- Apply a reliable method to a new cells and organisation task.
- Check the result and explain why the evidence supports it.
METHOD
A reliable three-step approach
- 1
State the scientific idea using accurate vocabulary.
- 2
Connect cause and effect with an observation or model.
- 3
Check the explanation against evidence, units and safety rules.
WORKED EXAMPLE
During a timed challenge for Grade 7, which structure controls most activities in a cell?
