📚 Year 12 SQA Science: Quick Guide to Memorising Key Terms | Year 12 SQA 科学：关键术语速记指南
For Year 12 students tackling SQA Higher Biology, Chemistry or Physics, a strong command of scientific terminology is not just helpful — it is essential. Examiners expect precise use of keywords in definitions, explanations and data analysis. This guide breaks down proven strategies to build, recall and apply the key terms that will earn you full marks in every section of your science papers.
对于正在攻克 SQA Higher 生物、化学或物理的 Year 12 学生来说，牢固掌握科学术语不仅仅是锦上添花——而是必不可少的。考官期望你在定义、解释和数据分析中精准使用关键词。本指南将拆解经过验证的策略，帮助你积累、回忆并运用那些能够为你每份科学试卷赢取满分的核心术语。
1. Why Mastering Terminology Matters | 掌握术语为何重要
In SQA Higher Sciences, many marks are awarded specifically for using the correct scientific term. A description of a biological process that uses ‘diffusion’ instead of ‘active transport’ can lose you a mark even if the wider answer is sensible. Similarly, in Chemistry, stating that an ‘ion’ is formed is not the same as explaining ‘ionic bonding’. Precision is a fundamental skill that separates A from C grade candidates.
在 SQA Higher 科学考试中，很多分数是专门奖励给使用正确科学术语的。一个生物过程描述如果把 ‘active transport’ 写成 ‘diffusion’，即使整体的回答看起来合理也会失分。同样，在化学中，说形成了 ‘ion’ 并不等同于解释 ‘ionic bonding’。精准度是区分 A 等考生与 C 等考生的基本技能。
Moreover, understanding terminology reduces cognitive load during exams. When you instantly recognise that an SQA question is asking about ‘enthalpy of combustion’ or ‘projectile motion’, you can focus on applying the relevant formulae and concepts rather than decoding the prompt. This fluency comes from deliberate practice with the vocabulary.
此外，理解术语能降低考试期间的认知负担。当你一眼就认出 SQA 题目是在问 ‘enthalpy of combustion’ 或 ‘projectile motion’ 时，你就能专注于运用相关的公式和概念，而不是花时间解读题干。这种流利度来自于对词汇的有意识练习。
2. The Power of Prefixes and Suffixes | 前缀与后缀的力量
Scientific language is built from a limited set of Greek and Latin word parts. Learning common prefixes like ‘endo-‘ (inside), ‘exo-‘ (outside), ‘hyper-‘ (over) and ‘hypo-‘ (under) instantly unlocks dozens of terms. In SQA Biology, ‘endocytosis’ and ‘exocytosis’ become easy to distinguish; in Chemistry, ‘exothermic’ and ‘endothermic’ are no longer confusing.
科学语言是由数量有限的希腊语和拉丁语词根构建而成的。学习常见的前缀，如 ‘endo-‘ (在内)、’exo-‘ (在外)、’hyper-‘ (超) 和 ‘hypo-‘ (低)，能立刻解锁几十个术语。在 SQA 生物中，’endocytosis’ 和 ‘exocytosis’ 变得容易区分；在化学中，’exothermic’ 和 ‘endothermic’ 也不再令人困惑。
Suffixes are equally powerful. ‘-osis’ indicates a process or condition, ‘-ase’ signals an enzyme, and ‘-itis’ means inflammation. Recognising these patterns helps you deduce meanings even if you encounter an unfamiliar term in a passage-based question. Dedicate a page in your revision notebook to these building blocks.
后缀同样强大。’-osis’ 表示过程或状态，’-ase’ 提示这是一种酶，而 ‘-itis’ 意味着炎症。识别这些模式有助于你在即使遇到基于短文的陌生术语时也能推断出含义。在你的复习笔记本中专门用一页来记录这些构词模块。
3. Common Greek and Latin Roots in SQA Science | SQA 科学中常见的希腊拉丁词根
Many students find it useful to maintain a table of high-yield roots. Below is a selection that appears frequently across Biology, Chemistry and Physics papers.
许多学生发现，维护一张高频词根表非常有用。下表精选了一些在生物、化学和物理试卷中频繁出现的词根。
| Root | Meaning | Example | 中文含义 |
|---|---|---|---|
| therm | heat | endothermic, thermistor | 热 |
| photo | light | photosynthesis, photon | 光 |
| cyto/cyte | cell | cytokinesis, erythrocyte | 细胞 |
| hydro | water | hydrolysis, hydrocarbon | 水 |
| electro | electric | electrolysis, electrode | 电 |
| oxid | oxygen/electron loss | oxidation, antioxidant | 氧化 |
Try to spot these roots when you read textbooks or past paper mark schemes. Associating a familiar root with a new term dramatically shortens memorisation time.
当你阅读教材或往年试卷评分方案时，尝试识别这些词根。将熟悉的词根与新术语联系起来，能大大缩短记忆所需的时间。
4. Biology Key Terms Made Easy | 生物学术语轻松记
SQA Higher Biology is dense with process-specific vocabulary. Use the ‘chunking’ method: group terms into conceptual families. For example, for cell transport, learn ‘diffusion, osmosis, active transport, endocytosis, exocytosis’ together. Compare them side by side in a table with columns for ‘energy requirement’, ‘direction of movement’ and ‘membrane protein involved’.
SQA Higher 生物富含过程性词汇。使用“组块”法：将术语按概念家族分组。例如，对于细胞运输，一起学习 ‘diffusion, osmosis, active transport, endocytosis, exocytosis’。在表格中将它们并排比较，列明 ‘能量需求’、’运动方向’ 和 ‘涉及的膜蛋白’。
For genetics terms, tell a story: ‘DNA is transcribed into mRNA, which is translated into a polypeptide chain at the ribosome.’ Connecting ‘transcription, translation, codon, anticodon’ in a flowchart embeds them in a logical sequence rather than as isolated words.
对于遗传学术语，可以讲一个故事：’DNA 被转录成 mRNA，mRNA 在核糖体处被翻译为多肽链。’ 将 ‘transcription, translation, codon, anticodon’ 以流程图连接起来，让它们嵌入逻辑序列而非孤立词汇。
5. Chemistry Terminology Demystified | 化学术语揭秘
Higher Chemistry introduces a language of functional groups, reaction types and bonding. A classic stumbling block is distinguishing between ‘electrophile’ and ‘nucleophile’. Use a mnemonic: Nucleophiles are Negative-loving (or Neutral with lone pairs) and Electrophiles are Electron-loving. Drawing a simple diagram of a curly arrow always alongside the term reinforces meaning.
Higher 化学引入了官能团、反应类型和化学键的语言。一个经典的绊脚石是区分 ‘electrophile’ 和 ‘nucleophile’。使用助记符：亲核试剂是爱负电的（或带有孤对电子的中性粒子），亲电试剂是爱电子的。在术语旁边始终画一个简单的弯箭头图，能强化其含义。
For systematic nomenclature, master the prefixes meth-, eth-, prop-, but- for carbon chain lengths. Then add suffixes: -ane, -ene, -ol, -al, -one. You can build nearly all organic molecule names from these bricks. Practice by naming ten random molecules daily until it becomes second nature.
对于系统命名法，掌握表示碳链长度的前缀 meth-, eth-, prop-, but-。然后加上后缀：-ane, -ene, -ol, -al, -one。你几乎可以用这些砖块拼出所有有机分子名称。每天随机为十个分子命名，直到它成为自然反应。
6. Physics Vocabulary in Context | 物理词汇语境记忆
Physics terminology often describes quantities, laws and relationships. Always pair a symbol with its full name and unit. For example: p = mv (momentum = mass × velocity), measured in kg m s⁻¹. Writing the equation in its symbolic form while saying the words aloud anchors the term through multiple senses.
物理术语通常描述量、定律和关系。始终将符号与其全称和单位配对。例如：p = mv (momentum = mass × velocity)，单位为 kg m s⁻¹。一边写出符号形式的方程，一边大声念出这些词，可以通过多种感官锚定术语。
Kinematics throws up easily confused pairs: ‘scalar’ versus ‘vector’, ‘speed’ versus ‘velocity’, ‘distance’ versus ‘displacement’. Make a two-column chart and rehearse it under timed conditions. Flash cards with one term on the front and its precise definition plus an example on the back are ideal for the Higher Physics exam.
运动学会出现容易混淆的词对：’scalar’ 与 ‘vector’，’speed’ 与 ‘velocity’，’distance’ 与 ‘displacement’。制作一个两列的图表，并在限时条件下反复练习。正面写术语、背面写精确定义和一个例子的抽认卡，是准备 Higher 物理考试的理想工具。
7. Visual Cues and Diagrams | 视觉线索与图表
Your brain stores images more efficiently than isolated text. Turn every tricky term into a doodle: for ‘isotonic’, draw a cell with equal arrows entering and leaving; for ‘dynamic equilibrium’, sketch a double arrow with equal-rate labels. These mental images are easily recalled during the stress of an exam.
你的大脑存储图像比存储孤立的文字更高效。把每个棘手的术语变成涂鸦：对于 ‘isotonic’，画一个带有进出等粗箭头的细胞；对于 ‘dynamic equilibrium’，画一个双向箭头并标注速率相等。在考试的高压环境下，这些心理图像更容易被回想起来。
Concept maps are particularly effective for linking vocabulary across topics. Start with a central theme like ‘Energy Changes in Chemistry’ and radiate out to ‘exothermic’, ‘enthalpy’, ‘activation energy’, ‘catalyst’ and ‘Hess’s law’. Use coloured arrows to show relationships.
概念图对于跨主题链接词汇尤为有效。从 ‘Energy Changes in Chemistry’ 这样的中心主题出发，向外辐射 ‘exothermic’、’enthalpy’、’activation energy’、’catalyst’ 和 ‘Hess’s law’。用彩色箭头显示它们之间的关系。
8. Acronyms and Mnemonics | 首字母缩略词与助记符
SQA science students love mnemonics. For the reactivity series in Chemistry, try “Please Stop Calling Me A Cute Zebra In The Lion Cage” (Potassium, Sodium, Calcium, Magnesium, Aluminium, Carbon, Zinc, Iron, Tin, Lead, Copper). For the electromagnetic spectrum, “Raging Martians Invade Venus Using X-ray Guns” (Radio, Microwave, Infrared, Visible, Ultraviolet, X-ray, Gamma).
SQA 科学学生都爱助记符。对于化学中的反应活性序列表，可以试试 “Please Stop Calling Me A Cute Zebra In The Lion Cage”（钾、钠、钙、镁、铝、碳、锌、铁、锡、铅、铜）。对于电磁波谱，可用 “Raging Martians Invade Venus Using X-ray Guns”（无线电、微波、红外、可见光、紫外、X射线、伽马射线）。
In Biology, a classic for the seven taxonomic ranks: “King Philip Came Over For Good Soup” (Kingdom, Phylum, Class, Order, Family, Genus, Species). Always verify that the mnemonic matches the current SQA specification order, and say it with a rhythm to embed it in long-term memory.
在生物中，一个用于七个分类等级的经典助记符是：”King Philip Came Over For Good Soup”（界、门、纲、目、科、属、种）。请务必验证助记符是否匹配当前的 SQA 教学大纲顺序，并有节奏地朗读，将它嵌入长期记忆中。
9. Flashcards and Active Recall | 抽认卡与主动回忆
Passive reading is the enemy of terminological mastery. Use the Leitner system with physical or digital flashcards: if you answer correctly twice, move the card to a less frequent review pile. Write the SQA definition on one side and the term on the other. Test yourself in both directions because papers ask you to define terms and to identify them from descriptions.
被动阅读是掌握术语的大敌。使用莱特纳系统配合实体或数字抽认卡：如果连续两次回答正确，就把卡片移到复习频率较低的盒子中。一面写上 SQA 的定义，另一面写上术语。双向进行自测，因为试卷既会要求你定义术语，也会要求你根据描述识别出术语。
Spaced repetition apps like Anki allow you to embed images and audio clips. For a term like ‘vasodilation’, include an audio recording of yourself saying the word and explaining it, along with a picture of widened blood vessels. The multi-modal reinforcement cements the vocabulary.
像 Anki 这样的间隔重复应用允许你嵌入图片和音频片段。对于像 ‘vasodilation’ 这样的术语，可以加入你自己朗读词语并解释的录音，以及一张血管扩张的图片。多模态的强化能巩固词汇。
10. Real-world Connections | 现实世界联系
Abstract terms become memorable when linked to everyday experience. ‘Osmosis’ is why slugs shrivel on salt. ‘Electromagnetic induction’ is how your wireless phone charger works. ‘Enzymes’ are the reason pineapple jelly won’t set. Whenever you encounter a scientific term, ask yourself: where have I seen this outside the textbook?
当抽象的术语与日常经验联系起来时，就会变得难忘。’Osmosis’ 解释了为什么蛞蝓在盐上会缩水。’Electromagnetic induction’ 是你的无线手机充电器的工作原理。’Enzymes’ 是菠萝果冻无法凝固的原因。每次遇到一个科学术语时，问自己：我在课本之外哪里见过它？
Keep a ‘Science in the News’ scrapbook. Paste articles about gene editing (CRISPR), renewable energy, or space missions, and highlight every technical term. Redefine them in your own words in the margin. This exercise converts passive awareness into exam-ready active vocabulary.
准备一本“新闻中的科学”剪贴簿。粘贴关于基因编辑 (CRISPR)、可再生能源或太空任务的报道，并高亮每个技术术语。在页边空白处用自己的话重新定义它们。这项练习能将消极的意识转化为考试就绪的主动词汇。
11. Practise with Past Paper Questions | 真题练习
SQA marking schemes are the ultimate glossary. Collect all the past papers and isolate the 1- and 2-mark ‘state’ or ‘name’ questions. These often demand a single precise term. Compile the answers into a list — you will notice that terms like ‘random’, ‘systematic’, ‘precision’, ‘replicates’, ‘dependent variable’ appear year after year in the experimental context.
SQA 评分方案是终极词汇表。收集所有往年试卷，并挑出那些 1 分或 2 分的 ‘state’ 或 ‘name’ 题。这些题通常要求一个精准的术语。把答案汇编成一份列表——你会注意到 ‘random’、’systematic’、’precision’、’replicates’、’dependent variable’ 这类词在实验语境下年年都出现。
Simulate exam conditions by answering vocabulary questions without notes. Mark them strictly according to the scheme — if the scheme says ‘activation energy’, do not award yourself a mark for ‘energy needed to start a reaction’. Use the mark schemes to refine your definitions until they are word-perfect.
通过不参考笔记来回答词汇题，以模拟考试条件。严格按照评分方案给自己打分——如果方案写的是 ‘activation energy’，就不要因为写了 ‘energy needed to start a reaction’ 而给自己分。利用评分方案不断打磨你的定义，直到字字无误。
12. Exam Day Tips for Terminology | 考试当天术语应对技巧
On the day of your SQA Higher Science exam, carry a small list of your ten most commonly confused word pairs to glance at just before you enter the hall. For many students these include ‘anion/cation’, ‘oxidising agent/reducing agent’, ‘genotype/phenotype’ and ‘velocity/acceleration’.
在你参加 SQA Higher 科学考试的那天，带上一张小纸条，写上你最常混淆的十组词对，在进入考场前快速扫一眼。对于许多学生来说，这些词对包括 ‘anion/cation’、’oxidising agent/reducing agent’、’genotype/phenotype’ 和 ‘velocity/acceleration’。
When answering, underline the key term in the question stem. If it asks for the name of a process, begin your answer with that name in bold or capital letters if the format allows, to mentally lock it in. For longer responses, define the term in your opening sentence — this shows the examiner you know it and structures your answer logically.
答题时，在题干的关键术语下划线。如果题目要求写出一个过程的名称，在格式允许的情况下，用粗体或大写字母给你的答案开头，以此在心理上锁定它。对于较长的回答，在开篇句就定义该术语——这向考官表明你懂它，并能从逻辑上组织你的答案。
