Science & Innovation word list

How to actually use science & innovation vocabulary in the exam

A word list is where vocabulary study starts and where most of it unfortunately stops. Lexical Resource is a quarter of your Writing and Speaking band, and it is not scored on how many unusual words you produce — it is scored on precision, collocation and word formation. A common word used exactly beats a rare one used approximately, every time.

• Learn the collocation, not the word. Knowing hypothesis means little until you know which words go with it — the verb it takes, the preposition that follows, whether it is countable. Errors of collocation are visible to examiners in a way that a smaller vocabulary is not, because they sound wrong rather than simple. When you record a new word, record it inside a phrase you could actually say.
• Learn the word family. Word formation is explicitly part of the criterion, so one entry should give you several: the noun, the verb, the adjective, the adverb. Being able to shift form mid-sentence is what lets you vary structure without reaching for new vocabulary, and it is far cheaper than learning more words.
• Precision over reach. Words like algorithm and substrate earn marks when they are the exact word for the idea and lose them when they are approximately right. If you are not sure of the shade of meaning, use the plain word you are certain of. An accurate simple sentence outscores an ambitious inaccurate one on both Lexical Resource and Grammatical Range.
• Do not memorise sentences. This is the trap. Pre-learned phrasing dropped into an answer regardless of fit is recognised immediately — examiners read thousands of scripts — and memorised language that does not fit the question is discounted from your assessment. Learn the words; build the sentences live.
• Practise producing, not recognising. Reading a list feels productive and builds only recognition, which is the wrong half. You need retrieval: cover the definitions and produce each word from its meaning, then write one sentence of your own for each. Recognition is what fails you under exam pressure when you need the word and cannot reach it.

Where science & innovation actually comes up. Topic vocabulary earns most in Speaking Part 3, where questions turn abstract and general, and in Writing Task 2, where a precise word can carry an argument a vague one cannot. It matters least in Listening and Reading, where you need to recognise paraphrase rather than produce it — which is exactly why passive list-reading feels like it is working while your Speaking and Writing bands stay where they were.

A realistic way to use this page. Take five words, not fifty. Write one sentence with each, on a question you might genuinely be asked. Say them out loud, because a word you have never pronounced will not arrive under pressure. Come back in a few days and produce them from the definitions alone. Five words you can use are worth more in the exam than fifty you can recognise, and that ratio is the whole reason most vocabulary study does not move a band.
