Science revision that sticks: diagrams, cards, practice
Science has a lot of facts, but it's more than a list to memorise. The students who do best usually combine remembering key facts with practising how to apply them. Here's a toolkit for biology, chemistry and physics.
Draw it from memory
Many science topics are processes or structures: the heart, the water cycle, electrolysis, a circuit. Try this:
- Look at a diagram for a minute.
- Cover it and draw it from memory, with labels.
- Check what you missed and fix it in a different colour.
Repeat a couple of days later. Drawing forces you to recall, and it's quicker than writing out pages of notes.
Flashcards for the facts
Use cards for definitions, key terms, equations and "state two" facts. Keep them to one idea each. For example:
- "What is the unit of resistance?"
- "Name the products of aerobic respiration."
- "What happens to reaction rate as temperature rises?"
Our guide to making flashcards quickly has the details.
Equations: learn which you're given
Check the exam board's equation sheet. Some equations are provided, some aren't. Learn the ones you must remember, and practise rearranging them, because that's where marks are lost. Then practise questions with units and significant figures.
Practise the longer answers
Questions worth four or six marks reward clear, ordered points. Try this approach:
- Underline the command word (describe, explain, compare, evaluate).
- Plan three or four bullet points before you write.
- Write in short, clear sentences using the correct key terms.
- Link ideas with "because", "so" and "which means".
Compare your answer against the mark scheme and look for which points you missed.
Learn the command words
Many marks are lost not from lack of knowledge but from answering the wrong question. "Describe" and "explain" are different: describing says what happens; explaining says why. Ask your teacher for the exam board's list of command words and make cards for them.
Required practicals
Don't skip them. Exams include questions on the practical work: method, variables, safety, results and conclusions. For each practical, make a one-page summary: aim, equipment, method in steps, independent, dependent and control variables, and what goes wrong.
Use past paper questions by topic
After revising a topic, do three to five exam questions on it. It's the best test of whether you can actually use what you've learned.
Where AI can help
AI can explain a stubborn concept in a new way, write practice questions from your notes and tell you what's missing from an answer. It can also get scientific details wrong, so check against your textbook or the specification before you memorise anything it says.
A simple weekly pattern
One topic a day: draw it, card it, question it. Then spend a short session each weekend on mixed questions from the earlier topics.
