📚 Year 13 SQA Sciences: Vocabulary & Terminology Quick Memorisation Guide | Year 13 SQA 科学：词汇术语速记指南
Mastering the precise vocabulary of SQA Physics, Chemistry, and Biology at Year 13 is the bridge between a simple grasp of concepts and top-band exam performance. Terms like ‘enthalpy’, ‘vector’, and ‘allele’ are not just words to be recognised; they are the language you need to frame definitions, interpret data, and construct explanations that meet SQA marking criteria. This guide provides you with active, research-backed techniques to internalise scientific terminology quickly, from root analysis to spaced repetition, ensuring you never lose marks because you mixed up ‘accuracy’ and ‘precision’ again.
在 Year 13 阶段掌握 SQA 物理、化学和生物的精准词汇，是从大致理解概念跃升到考试高分的桥梁。“焓”、“矢量”、“等位基因”这类术语绝非需要单纯辨认的单词，它们是你在构建定义、解读数据和撰写符合 SQA 评分标准解释时所需的语言。本指南为你提供了经过研究验证的主动速记技巧，从词根分析到间隔重复，确保你不会再因为混淆了“准确度”和“精确度”而失分。
1. Why Terminology Matters | 词汇术语为何重要
SQA examiners repeatedly highlight that candidates lose easy marks by using loose, everyday language instead of precise scientific vocabulary. For instance, writing ‘heat energy’ when you mean ‘enthalpy change’ in a Chemistry context, or calling an object ‘moving’ instead of ‘accelerating’ in Physics, can prevent you from showing the depth of understanding required for higher grades. Terminology is the foundation for linking concepts; a correct definition often carries a mark on its own, and it builds your credibility in extended response questions.
SQA 考官反复强调，考生因使用宽松的日常语言而非精确的科学词汇而轻易失分。例如，在化学语境中你想表达“焓变”却写成“热量”，或者在物理中称一个物体在“移动”而非“加速”，这些都会阻碍你展现出获得高等级所需的深度理解。术语是连接概念的基础；一个正确的定义本身往往就值一分，并且能为你在拓展回答中建立可信度。
Furthermore, scientific words often carry their meaning in their structure. Recognising this transforms memorisation from rote learning into a logical puzzle. When you understand that ‘exothermic’ contains ‘exo-‘ (out) and ‘therm’ (heat), you instantly know it describes energy being given out. This makes recall far more reliable under exam pressure.
此外，科学词汇的含义往往蕴藏在其构词结构中。认识到这一点，就能把记忆从死记硬背转变为逻辑推理。当你明白“exothermic”（放热的）包含“exo-”（外）和“therm”（热）时，你立刻明白它描述的是能量向外释放。这让考试压力下的回忆变得可靠得多。
2. Unlocking Roots, Prefixes, and Suffixes | 破解词根、前缀与后缀
Decoding a term’s Greek or Latin roots is like having a secret key. In Biology, ‘hypertonic’ breaks down into ‘hyper-‘ (over/above) and ‘tonos’ (tension/pressure), telling you a solution has a higher solute concentration. In Physics, ‘isochoric’ (iso- equal, -chore space) immediately indicates a constant volume process. Adopt the habit of looking at every new term as a combination of building blocks; you will drastically reduce the number of completely unfamiliar words.
破解一个术语的希腊语或拉丁语词根就像拥有一把秘钥。在生物学中，“hypertonic”（高渗的）可分解为“hyper-”（过度/高于）和“tonos”（张力/压力），告诉你一种溶液溶质浓度更高。在物理学中，“isochoric”（等容的，iso-相同，-chore空间）直接表明这是一个体积不变的过程。养成习惯，把每一个新术语都视为构词模块的组合；你遇到的完全陌生的词汇数量将大幅减少。
Create a simple log in your notes with three columns: Prefix/Suffix, Meaning, and Example. Common ones to learn include ‘photo-‘ (light) as in photosynthesis; ‘electro-‘ (electricity) as in electrolyte; ‘-lysis’ (splitting) as in hydrolysis; ‘-phobic’ (fearing/repelling) as in hydrophobic. Even advanced SQA terms reveal their secrets this way: ‘electrophilic addition’ (electron-loving addition) becomes much clearer.
在你的笔记中创建一个简单的三列表格：前缀/后缀、含义、范例。需要掌握的一些常见构词成分包括：’photo-‘（光），如 photosynthesis（光合作用）；’electro-‘（电），如 electrolyte（电解质）；’-lysis’（分解），如 hydrolysis（水解）；’-phobic’（疏/惧），如 hydrophobic（疏水的）。即便是高级的 SQA 术语也会这样揭示自身秘密：“electrophilic addition”（亲电加成）就清晰多了。
3. Physics in Words: Mechanics and Waves | 物理词汇：力学与波动
Mechanics is filled with pairs that must be distinguished. ‘Displacement’ is the vector distance in a given direction, while ‘distance’ is a scalar. Learn to attach the phrase ‘per unit time’ mentally to the definition of a rate: ‘velocity’ is displacement per unit time. Visualising a car moving north-east at 20 m s⁻¹ embeds both magnitude and direction, cementing the vector idea.
力学中充满了必须区分的成对术语。“位移”（displacement）是给定方向上的矢量距离，而“距离”（distance）是标量。学着在心里把“每单位时间”这个短语附加到速率的定义上：“速度”（velocity）就是每单位时间的位移。想象一辆汽车以 20 m s⁻¹ 的速度向东北方向行驶，这同时嵌入了大小和方向，巩固了矢量的概念。
In waves, the language describes behaviour: ‘diffraction’ is the spreading of a wave when it meets an obstacle or gap; ‘refraction’ is the change in direction as it crosses a boundary between media. A frequent error is mixing up ‘amplitude’ (maximum displacement from rest) and ‘wavelength’ (distance between successive identical points). Use the phrase ‘amplitude gives volume/loudness’ to link the physical quantity to its effect in sound.
在波动中，术语描述行为：“衍射”（diffraction）是波遇到障碍物或狭缝时传播开来的现象；“折射”（refraction）是波穿过介质边界时方向发生改变。一个常见错误是混淆“振幅”（amplitude，离开平衡位置的最大位移）和“波长”（wavelength，相邻相同点间的距离）。可以用“振幅决定音量/响度”这句话，将物理量与它在声音中的效应联系起来。
The photoelectric effect introduces ‘threshold frequency’ (the minimum frequency to eject electrons) and ‘work function’ (the minimum energy for electron emission). Remembering that the work function is a property of the metal and is symbolised by the Greek letter phi (Φ) helps you link equation terms. In Advanced Higher, terms like ‘angular momentum’ and ‘torque’ need precise vector descriptions, so always visualise the right-hand rule for direction.
光电效应引入了“阈值频率”（threshold frequency，能够打出电子的最低频率）和“功函数”（work function，电子发射所需的最小能量）。记住功函数是金属的一种属性且用希腊字母 phi (Φ) 表示，有助于联系方程项。在 Advanced Higher 课程中，“角动量”（angular momentum）和“力矩”（torque）等术语需要精确的矢量描述，因此要总是用右手定则形象化其方向。
4. Chemistry Code: Moles, Bonding, and Reactions | 化学密码：摩尔、化学键与反应
The mole is the chemist’s counting unit, linking mass, number of particles, and gas volume. ‘Avogadro’s constant’ (6.02 × 10²³ mol⁻¹) is the number of entities in one mole. A classic exam trap asks for the ‘molar mass’ (mass of one mole, g mol⁻¹) when you have only calculated ‘relative molecular mass’ (no units). Always write units in your definition: ‘molar volume’ is the volume occupied by one mole of a gas, usually stated in dm³ mol⁻¹ at standard conditions.
摩尔是化学家的计数单位，连接了质量、粒子数目和气体体积。“阿伏伽德罗常数”（6.02 × 10²³ mol⁻¹）就是一摩尔实体中的个数。经典的考试陷阱会在你只算出了“相对分子质量”（无单位）时，要求给出“摩尔质量”（一摩尔的质量，g mol⁻¹）。记得在你的定义中总写上单位：“摩尔体积”是一摩尔气体所占据的体积，通常以标准状况下的 dm³ mol⁻¹ 表示。
Bonding terms describe how atoms are held. ‘Electronegativity’ is a measure of the pull on bonding electrons; a large difference leads to ‘ionic bonding’, while a small or zero difference gives ‘covalent’ or ‘metallic bonding’. The term ‘dative covalent bond’ (also called coordinate bond) relies on both electrons coming from the same atom. Understand the bonding continuum, from non-polar covalent to ionic, rather than treating them as isolated boxes.
化学键术语描述原子如何被维系在一起。“电负性”是衡量对键合电子拉引能力的指标；电负性差值很大导致“离子键”，差值很小或为零产生“共价键”或“金属键”。“配位共价键”（也称配位键）这一术语依赖于两电子都来自同一原子。要理解从非极性共价键到离子键的键合连续体，而不是把它们当作孤立的分类来看待。
In physical chemistry, ‘enthalpy’ is heat content at constant pressure; ‘entropy’ is a measure of disorder. SQA questions love to ask about the feasibility of a reaction using ‘Gibbs free energy’: ΔG = ΔH – TΔS. Remember that ΔG must be negative for a feasible reaction. Terms like ‘heterogeneous’ (different phases) and ‘homogeneous’ (same phase) equilibrium must be correctly applied when writing equilibrium expressions. Keep a table of these contrasting pairs handy.
在物理化学中，“焓”是恒压下的热含量；“熵”是混乱度的一种量度。SQA 试题喜欢考查用“吉布斯自由能”（ΔG = ΔH – TΔS）判断反应可行性。要记住一个可行反应必须满足 ΔG < 0。书写平衡表达式时，必须正确应用“多相”（heterogeneous）和“均相”（homogeneous）平衡等术语。手边备好一张这些对照术语的表格会很有帮助。
5. Biology’s Lexicon: Cells, Genetics, and Ecology | 生物学术语：细胞、遗传与生态
Cell biology builds on organelles. ‘Mitochondrion’ (plural mitochondria) is the site of aerobic respiration, while ‘chloroplast’ is for photosynthesis. Do not confuse the ‘cell wall’ (fully permeable, structural, found in plants) with the ‘cell membrane’ (selectively permeable, found in all cells). In membranes, ‘active transport’ requires energy (ATP) to move substances against a concentration gradient, whereas ‘facilitated diffusion’ uses protein channels and no energy.
细胞生物学建立在细胞器之上。“线粒体”（mitochondrion，复数 mitochondria）是有氧呼吸的场所，而“叶绿体”（chloroplast）则负责光合作用。不要把“细胞壁”（全透性，结构支持，存在于植物细胞）与“细胞膜”（选择透过性，所有细胞皆有）混淆。在膜运输中，“主动运输”需要能量（ATP）逆浓度梯度搬运物质，而“易化扩散”使用蛋白质通道且不需要能量。
Genetics and evolution have a precise vocabulary. An ‘allele’ is a variant form of a gene. ‘Genotype’ is the genetic constitution, ‘phenotype’ is the observable characteristic. Disruptive, stabilising, and directional selection are patterns of natural selection that SQA expects you to distinguish. Mastering the steps from ‘transcription’ (DNA to mRNA) to ‘translation’ (mRNA to polypeptide) relies on using correct terms like ‘codon’, ‘anticodon’, and ‘peptide bond’. Avoid writing ‘the base U replaces T’ without specifying it occurs in RNA.
遗传与进化拥有一套精准的词汇。“等位基因”是基因的变体形式。“基因型”是遗传组成，“表现型”是可观察的特征。分裂选择、稳定选择和定向选择是 SQA 期望你区分的自然选择模式。掌握从“转录”（DNA 到 mRNA）到“翻译”（mRNA 到多肽）的步骤有赖于正确使用诸如“密码子”、“反密码子”和“肽键”等术语。不要仅仅写“碱基 U 替代了 T”，而不说明这发生在 RNA 中。
In ecology, ‘biodiversity’ incorporates species richness and relative abundance. ‘Niche’ refers to the role an organism plays in its ecosystem, encompassing its habitat, feeding relationships, and interactions. Be careful to distinguish ‘population’ (same species, same area) from ‘community’ (all populations in an area) and ‘ecosystem’ (community plus abiotic factors). These hierarchical terms appear in data analysis questions regularly.
在生态学中，“生物多样性”包含了物种丰富度和相对丰度。“生态位”指的是一个生物在其生态系统中所扮演的角色，包括其生境、摄食关系和相互作用。要小心区分“种群”（同一地区同种生物）、“群落”（一个地区所有种群）和“生态系统”（群落加上非生物因素）。这些层级术语会频繁出现在数据分析题中。
6. Units, Symbols, and Abbreviations | 单位、符号与缩写
SQA mark schemes are ruthless about missing or incorrect units. ‘Current’ (I) in amperes (A), ‘potential difference’ (V) in volts (V), ‘resistance’ (R) in ohms (Ω). In Physics, the symbol fs−1 (using superscript properly, I’ll use Unicode: s⁻¹) stands for ‘per second’. Learn the standard prefixes: nano- (n, 10⁻⁹), micro- (µ, 10⁻⁶), milli- (m, 10⁻³), centi- (c, 10⁻²), kilo- (k, 10³), mega- (M, 10⁶). Mistakes with powers of ten are extremely common.
SQA 的评分方案对缺失或错误的单位毫不留情。“电流”（I）的单位是安培（A），“电势差”（V）的单位是伏特（V），“电阻”（R）的单位是欧姆（Ω）。在物理中，符号 s⁻¹ 表示“每秒”。学习标准词头：纳（n, 10⁻⁹）、微（µ, 10⁻⁶）、毫（m, 10⁻³）、厘（c, 10⁻²）、千（k, 10³）、兆（M, 10⁶）。10 的幂次错误极其常见。
In Chemistry, state symbols (s), (l), (g), (aq) are part of the terminology and are required in equations. ‘STP’ stands for Standard Temperature and Pressure, but SQA commonly uses ‘room temperature and pressure’ or standard conditions: 298 K and 100 kPa. Meanwhile, in Biology, ‘ATP’, ‘NADPH’, and ‘RuBP’ must be written out in full forms at least once before using abbreviations, and you must know their roles precisely to secure those marks in photosynthesis and respiration questions.
在化学中，状态符号（s）、（l）、（g）、（aq）是术语的一部分，方程式里必须包含。’STP’ 代表标准温度和压力，但 SQA 常用“室温和常压”或标准条件：298 K 和 100 kPa。同时，在生物学中，’ATP’、’NADPH’ 和 ‘RuBP’ 这些缩写在使用前至少需要写出一次全称，而且你必须精确知道它们在光合作用与呼吸问题中的作用才能拿到分数。
7. Mnemonics and Acrostic Tricks | 助记术与首字母缩略诀窍
Creating a memorable phrase from the first letters of a sequence can lock in information. For the electromagnetic spectrum in order of decreasing wavelength, ‘Raging Martians Invaded Venus Using X-ray Guns’ gives Radio, Microwaves, Infrared, Visible, Ultraviolet, X-rays, Gamma. In Biology, ‘King Prawn Curry Or Fat Greasy Sausages’ helps recall classification: Kingdom, Phylum, Class, Order, Family, Genus, Species.
用一组信息的首字母编一句好记的话，可以将信息牢牢锁定。对于波长递减的电磁波谱，“Raging Martians Invaded Venus Using X-ray Guns”（愤怒的火星人用 X 射线枪入侵金星）给出了无线电波、微波、红外线、可见光、紫外线、X 射线和伽马射线。在生物学中，“King Prawn Curry Or Fat Greasy Sausages”有助于回忆分类阶元：界、门、纲、目、科、属、种。
For the reactivity series, a strong mnemonic such as ‘Please Stop Calling Me A Zebra In The Library’ can map to Potassium, Sodium, Calcium, Magnesium, Aluminium, Zinc, Iron, Tin, Lead (for part of the series). Homemade mnemonics work best; the process of constructing one forces you to actively engage with the material. Pair the nonsense phrase with a vivid mental image to strengthen the cue.
对于金属活性顺序，一句像“Please Stop Calling Me A Zebra In The Library”（请别再在图书馆里叫我斑马）这样的强力助记句可以对应钾、钠、钙、镁、铝、锌、铁、锡、铅（部分顺序）。自己编的助记句效果最好；构建的过程会迫使你主动与材料互动。搭配一个荒诞的、生动的心理图像来强化提示线索。
8. Visual Aids and Concept Maps | 视觉辅助与概念图
Science is rich in diagrams: ray diagrams, reaction coordinate graphs, and genetic crosses. For a term like ‘action potential’, draw the graph of membrane potential versus time, labelling the resting potential, depolarisation, and repolarisation. Attach the terminology directly to the curve: the steep rise is caused by Na⁺ ion channels opening. This links the word to a visual shape, making it a single memory chunk.
科学中富含图表：光线图、反应坐标图和遗传杂交图。对于像“动作电位”这样的术语，画出膜电位随时间变化的曲线，标注静息电位、去极化和复极化。将术语直接贴在曲线上：陡峭上升由 Na⁺ 离子通道开放所致。这会把词汇与一个视觉形状联系起来，使其成为一个单一的记忆组块。
Concept maps excel at connecting terminology across topics. In the centre, place ‘Photosynthesis’. Connect it to ‘light-dependent reactions’ and ‘Calvin cycle’, then branch further to ‘photolysis’, ‘NADPH’, ‘RuBisCo’. Each arrow should have a short phrase: ‘uses light energy to split water’. This shows you not only what the word means, but how it functions in the system—exactly the level of synthesis SQA demands.
概念图擅长将跨主题的术语连接起来。在中心位置写上“光合作用”。把它连接到“光依赖反应”和“卡尔文循环”，再进一步分支到“光解作用”、“NADPH”和“RuBisCo”。每个箭头上应写一个短短语：“利用光能分解水”。这不仅让你知道词汇的含义，还展示了它在系统中的功能——这正是 SQA 所要求的综合层面。
9. Flashcards and Spaced Repetition | 闪卡与间隔重复
Write the term on one side of a physical or digital flashcard, and the definition, a diagram, and an example context on the other. For ‘Le Chatelier’s principle’, the back should state: ‘If a system at equilibrium is subjected to a change, the equilibrium shifts to oppose the change’, and an example such as adding reactant shifts towards products. Review using spaced repetition: intervals of 1 day, 3 days, 1 week, 1 month. This algorithm battles the forgetting curve efficiently.
在纸质或数字闪卡的一面写下术语，另一面写上定义、图表和例句语境。对于“勒夏特列原理”，卡片背面应写上：“若平衡系统受到外部改变，平衡会向着减弱这种改变的方向移动”，并附上一个例子，如增加反应物则平衡移向产物方向。使用间隔重复进行复习：间隔为 1 天、3 天、1 周、1 个月。这一算法能有效抗击遗忘曲线。
Avoid the trap of flipping the card and thinking ‘I knew that’ without truly testing. Force yourself to articulate the full definition, including units if it is a quantity. If you stumble, return the card to your daily deck. With terms like ‘buffer solution’, make sure you can explain how it resists pH change using the equilibrium between a weak acid and its conjugate base. Flashcard study must be active, not passive.
避免掉入翻过卡片后自以为“我知道”却并未真正测试的陷阱。强迫自己完整叙述定义，如果是物理量还要包括单位。如果你卡壳了，就把这张卡片放回每日复习的牌堆。对于像“缓冲溶液”这样的术语，要确保你能解释它如何利用弱酸与其共轭碱之间的平衡来抵抗 pH 变化。闪卡学习必须是主动的，而非被动的。
10. Active Recall in Context | 上下文中的主动回忆
Reading notes is insufficient. Close the book and try to recall the exact phrasing of ‘relative atomic mass’ (the weighted mean mass of an atom of an element relative to 1/12th the mass of an atom of carbon-12). Then open your textbook to verify every word. Practise writing SQA-style definitions from memory under timed conditions; the phrasing often has legally precise wording that earns the mark. The term ‘conservation of momentum’, for example, must include ‘in the absence of external forces’.
光看笔记是不够的。合上书，尝试回忆“相对原子质量”（元素一个原子的加权平均质量与一个碳-12 原子质量的 1/12 的比值）的确切措辞。然后打开课本核对每一个字。练习在计时条件下凭记忆写出 SQA 风格的定义；这些措辞往往有着法条般的精确性，这样才得分。例如，“动量守恒”一词必须包含“在无外力作用的情况下”。
In Chemistry, write out full ionic equations to recall ‘spectator ions’ and ‘redox’ terminology. When studying ‘standard enthalpy of combustion’, draw a Hess’s law cycle and label the pathway, saying the definition aloud: the enthalpy change when one mole of a substance is burned completely in oxygen under standard conditions. Engaging multiple senses—writing, speaking, drawing—builds multiple retrieval routes to the term.
在化学中，写出完整的离子方程式来回忆“旁观离子”和“氧化还原”等术语。学习“标准燃烧焓”时，画出一个盖斯定律循环图并标出路径，同时大声说出定义：一摩尔物质在标准状况下于氧气中完全燃烧时的焓变。调动多重感官——写、说、画——可以构建出提取该术语的多条路径。
11. Common Pitfalls and Confusing Pairs | 常见陷阱与易混淆术语对
Here are high-risk terms that must be teased apart: ‘Accuracy’ vs ‘Precision’ — accuracy is how close a measurement is to the true value, precision is the spread of repeated measurements. In Chemistry, ‘molecular formula’ vs ’empirical formula’ — the empirical is the simplest whole-number ratio. In Biology, ‘genome’ (all genetic material) vs ‘gene’ (a segment coding for a polypeptide). Create a dedicated ‘confusion list’ in your revision notes and write contrasting definitions side by side.
以下是一些高风险术语，必须加以辨析：“准确度”与“精确度”——准确度指测量值接近真实值的程度，精确度指重复测量结果的散布程度。在化学中，“分子式”与“实验式”——实验式是最简整数比。在生物学中，“基因组”（全部遗传物质）与“基因”（编码多肽的一段序列）。在你的复习笔记中创建一个专门的“易混淆清单”，将对照定义并排写出。
Another classic mix-up: ‘ionic bond’ is the electrostatic attraction between oppositely charged ions, not the transfer of an electron (that is the process leading
