Key learning points
- A method provides step-by-step instructions for how to carry out an investigation.
- Methods should include how equipment is used and specific amounts of substances used.
- Methods should be written so that they are both repeatable and reproducible.
- Methods are written concisely, using clear language and command words.
Common misconception
Sometimes pupils like to write methods in paragraph form, which can be difficult to follow.
Suggest pupils draw labelled diagrams of key steps, write a sentence to describe each diagram, then go back to number them in order.
