ScienceHow to study science
Science is not a list of facts to be learnt by heart. It is a way of asking "why?" and "how do we know?". Students who study it that way find that it needs less memory, not more.
1. Understand before you memorise
Read a topic the way you would read a story: what is the problem, what is the idea that solves it? If you can explain the water cycle to your younger brother or sister in your own words, you have understood it. If you can only repeat the book's sentences, you have not.
2. Learn the words
Every topic has five or six key terms: evaporation, conductor, inertia. Science questions are often simply "define" or "what is meant by". Keep a small notebook of terms, each with a one-line meaning in your own words and one example.
3. Draw
A labelled diagram is worth half a page of writing, and examiners give marks for it. Practise drawing the main diagrams from memory: the parts of a plant, the water cycle, a circuit, the heart. Use a pencil, draw large, and label with straight lines that do not cross.
4. Do, do not just read
Most ideas in school science can be seen at home with a glass, a torch, a magnet or a few seeds. Every topic on this site ends with a small activity. A thing you have seen with your own eyes is never forgotten. Always take an adult's help with heat, flames, sharp tools and anything electrical beyond a torch cell.
5. Ask why
Why do wet clothes dry faster on a windy day? Why is the sky dark at night? Why does a steel spoon feel colder than a wooden one? Connecting what you study to what you see makes science interesting, and "application" questions in exams easy.
6. Practise numericals step by step
In physics and chemistry sums, write four lines every time: what is given, what is to be found, the formula, and the working with units. Most marks are lost not on the idea but on units and careless arithmetic.
7. Test yourself
After reading a topic, close the page and answer the quick questions. Re-reading feels comfortable but teaches little; recalling is what builds memory. Come back to the same questions after three days and again after two weeks.
8. Use your textbook as the final word
This site explains ideas in simple language to help you understand. For examinations, your prescribed textbook decides what is in the syllabus, which definitions to write and how much detail is needed. Use both: understand here, then read the chapter in your book.
A plan for one topic
- Read the explanation once, slowly (10 minutes).
- Write the key terms in your notebook (5 minutes).
- Draw the diagram, if there is one (5 minutes).
- Do the activity when you can.
- Answer the quick questions without looking (5 minutes).
- Read the same chapter in your textbook and solve its exercises.
