Reference excerpt

Sri Lanka is a tropical island situated close to the southern tip of India. It is situated in the middle of Indian Ocean.

Worked examples

Example 1 — a first encounter with List of common commercial fish of Sri Lanka

Start with the simplest possible case. Write down what List of common commercial fish of Sri Lanka claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of common commercial fish of Sri Lanka before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of common commercial fish of Sri Lanka ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.
