Building a strong foundation in science starts with mastering the key vocabulary. This guide will show you effective techniques to memorise essential Year 7 AQA science terms quickly and retain them for the long term.
在科学上打下坚实的基础，首先要掌握关键词汇。本指南将向你展示有效的技巧，帮助你快速记忆 Year 7 AQA 科学的基本术语，并长期记住它们。
1. Why Science Vocabulary Matters | 为什么科学词汇很重要
In Year 7, you will encounter many new scientific words. These terms are not just labels; they allow you to describe observations, explain phenomena, and answer exam questions accurately. Without a solid vocabulary, understanding concepts becomes much harder — it is like trying to build a house without knowing the names of the tools and materials.
在七年级，你会遇到许多新的科学词汇。这些术语不仅仅是标签，它们能让你准确描述观察结果、解释现象并回答考题。没有扎实的词汇基础，理解概念会变得困难得多——就像试图建造一座房子却不认识工具和材料的名称一样。
Furthermore, many scientific terms appear across biology, chemistry and physics. Once you learn a word like 'organism' or 'particle', you can use it in multiple topics, strengthening your overall science knowledge.
此外，许多科学术语在生物、化学和物理中都会出现。一旦你学会一个词，比如“生物体”或“粒子”，你就可以在多个主题中使用它，从而巩固你的整体科学知识。
2. Root Words, Prefixes and Suffixes | 词根、前缀和后缀
Many science words are built from Greek or Latin roots, prefixes and suffixes. Learning these building blocks helps you decode unfamiliar terms. For instance, 'bio-' means life, so 'biology' is the study of life. 'Photo-' means light, therefore 'photosynthesis' uses light to make food. 'Micro-' means small, so a 'microscope' lets you see tiny things.
许多科学词汇是由希腊或拉丁语词根、前缀和后缀构成的。学习这些构成要素有助于你解读不熟悉的术语。例如，“bio-”表示生命，所以“biology”是研究生命的学科。“photo-”表示光，因此“photosynthesis”是利用光制造食物。“micro-”表示微小，所以“microscope”能让你看到微小的东西。
Below is a table of common affixes that appear frequently in Year 7 AQA science. Try to spot them in your textbook.
下面是一个常见词缀表，这些词缀经常出现在 Year 7 AQA 科学中。试着在你的课本中发现它们吧。
| Prefix/Suffix | Meaning | Example | 中文示例 |
|---|---|---|---|
| bio- | life | biology | 生物学 |
| photo- | light | photosynthesis | 光合作用 |
| micro- | small | microorganism | 微生物 |
| -ology | study of | geology | 地质学 |
| therm- | heat | thermometer | 温度计 |
| -scope | look at | telescope | 望远镜 |
Whenever you meet a new term, break it into parts and ask yourself if you recognise any of these pieces. This strategy turns long, intimidating words into manageable chunks.
每当你遇到一个新术语时，把它拆成几部分，问问自己是否认识其中的任何部分。这种策略能把又长又吓人的单词变成可以轻松应对的小块。
3. Acronyms and Mnemonics | 首字母缩略词与记忆术
Acronyms and mnemonics condense lists of terms into memorable sequences. One famous example for life processes is MRS GREN, which stands for Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion and Nutrition. By remembering this single name, you can recall all seven characteristics of living things.
首字母缩略词和记忆术将一系列术语浓缩成容易记住的序列。生命过程的著名例子是 MRS GREN，它代表 Movement（运动）、Respiration（呼吸）、Sensitivity（感应）、Growth（生长）、Reproduction（生殖）、Excretion（排泄）和 Nutrition（营养）。通过记住这一个名字，你就能回忆起生物的全部七个特征。
In Chinese, you can create a catchy phrase: "运动呼吸感生长，生殖排泄加营养" (yùn dòng hū xī gǎn shēng zhǎng, shēng zhí pái xiè jiā yíng yǎng) to match the seven processes. Rhyming phrases make recall almost automatic.
中文里你可以编一个朗朗上口的短语：“运动呼吸感生长，生殖排泄加营养”，对应这七个过程。押韵的短语让回忆几乎自动化。
You can invent your own mnemonics for other groups, such as the order of the planets (My Very Easy Method Just Speeds Up Naming Planets) or the colours of the rainbow (Richard Of York Gave Battle In Vain). Personalised mnemonics are often the most powerful because they mean something to you.
你还可以为其他组合发明自己的记忆术，比如行星的顺序（My Very Easy Method Just Speeds Up Naming Planets）或彩虹的颜色（Richard Of York Gave Battle In Vain）。个性化的记忆术往往最强大，因为它们对你有特殊意义。
4. Key Biology Terms and Memorisation Tips | 重要生物学术语及记忆技巧
Biology vocabulary covers cells, organs, ecosystems and more. Start with the animal cell: nucleus (control centre), cytoplasm (jelly-like substance where reactions occur), cell membrane (skin that controls entry and exit) and mitochondria (powerhouses). Think of the cell as a busy city — the nucleus is the town hall, mitochondria are power stations, and the cell membrane is the city wall with gates.
生物学词汇涵盖细胞、器官、生态系统等。先从动物细胞开始：nucleus（控制中心）、cytoplasm（发生反应的果冻状物质）、cell membrane（控制进出的皮肤）和 mitochondria（能量工厂）。把细胞想象成一座繁忙的城市——细胞核是市政厅，线粒体是发电站，细胞膜是带有大门的城墙。
Plant cells add chloroplasts (for photosynthesis) and a cell wall (rigid outer layer). To remember chloroplast, notice it contains 'chloro-' (green) and 'plast' (body) — little green bodies that catch sunlight. The cell wall reminds you that plants stand tall without bones because their walls give them support.
植物细胞还有 chloroplast（叶绿体，进行光合作用）和 cell wall（细胞壁，坚硬的外层）。要记住叶绿体，注意它包含“chloro-”（绿色）和“plast”（体）——捕捉阳光的绿色小颗粒。细胞壁让你想起植物没有骨骼却能直立，因为它们的壁提供支撑。
eating this sequence aloud helps cement the hierarchy. You can also create a sentence like "Clever Tigers Only Observe Owls" to remember Cells, Tissues, Organs, Organ systems, Organism.
学习器官系统时，画一个流程图：细胞→组织→器官→器官系统→生物体。大声重复这个顺序有助于巩固层级关系。你还可以编一个句子，比如“聪明的老虎只观察猫头鹰”，来记住细胞、组织、器官、器官系统和生物体。
5. Key Chemistry Terms and Memorisation Tips | 重要化学术语及记忆技巧
Chemistry in Year 7 introduces atoms, elements, compounds and mixtures. An atom is the smallest particle of an element, while an element is a substance made of only one type of atom. A compound contains two or more different elements chemically bonded, whereas a mixture simply has different substances jumbled together but not bonded.
七年级化学引入了原子、元素、化合物和混合物。原子是元素的最小粒子，而元素是仅由一种原子组成的物质。化合物含有两种或更多不同元素，并通过化学键结合，而混合物只是不同的物质混在一起，但没有结合在一起。
A simple memory trick: think of an element as a pure note on a piano, a compound as a chord (different notes played together and locked), and a mixture as a bowl of fruit salad — the ingredients are separate and can be picked out.
一个简单的记忆窍门：把元素想象成钢琴上的一个纯音符，化合物是和弦（不同的音符一起弹奏并锁定），混合物则像一碗水果沙拉——原料是分开的，可以挑出来。
For chemical symbols, many derive from Latin names, which can be tricky. Sodium is Na (from natrium), Potassium is K (from kalium), Iron is Fe (from ferrum). You can use stories: "A naughty (Na) sodium atom always loses an electron" or "Kalium (K) keeps potassium in your banana." Learning these links makes the symbols stick.
化学符号很多来自拉丁名称，这有点棘手。钠是 Na（来自 natrium），钾是 K（来自 kalium），铁是 Fe（来自 ferrum）。你可以用故事来记：“钠原子总是淘气地（Naughty）失去一个电子”或“Kalium (K) 让你香蕉里的钾保持活力”。学会这些联系能让符号更容易记住。
The periodic table organises elements. A phrase like "Happy Harry Hears Lively Bees Buzzing" for the first few elements (Hydrogen, Helium, Lithium, Beryllium, Boron) can help. Always practise writing symbols with the first letter capitalised and the second lowercase, e.g. Mg for magnesium, not MG.
元素周期表将元素组织起来。用一句话如“Happy Harry Hears Lively Bees Buzzing”来记前几个元素（氢、氦、锂、铍、硼）会有帮助。一定要练习书写符号，首字母大写，第二个字母小写，比如镁是 Mg，不是 MG。
6. Key Physics Terms and Memorisation Tips | 重要物理术语及记忆技巧
Physics vocabulary includes words for forces, energy and motion. A force is simply a push or a pull, measured in newtons (N). Friction is a force that opposes motion; you can remember it because 'friction' sounds like 'freaking' slow-down action. Gravity is the force that pulls objects towards each other — think of 'gravity' grasping you to the ground.
物理词汇包括力、能量和运动相关词语。力简单来说就是推或拉，以牛顿（N）为单位。摩擦力是阻碍运动的力；你可以因为“friction”听起来像“freaking”（令人恼火的）减速动作而记住它。重力是物体之间相互吸引的力——想象“gravity”把你抓向地面。
Key formulas for Year 7 often involve speed and pressure. The speed equation can be displayed as:
Speed = Distance ÷ Time
中文公式：速度 = 距离 ÷ 时间。 (speed), the less time you take for the same distance. Another important one is pressure:
Pressure = Force ÷ Area
中文公式：压强 = 力 ÷ 面积。Imagine standing on soft sand — ure so you do not sink. High heels concentrate force on a small area, increasing pressure.
想象站在柔软的沙子上——穿平底鞋会把体重分散到更大的面积上，降低压强，这样你就不会陷下去。高跟鞋则将力集中到一个很小的面积上，增加了压强。
When studying energy, remember the eight energy stores using a mnemonic: "Great Kings Eat Magnetic Chocolate Cakes Every Night" (Gravitational, Kinetic, Elastic, Magnetic, Chemical, Thermal, Electrostatic, Nuclear). Pair each store with a real-life example: a book on a shelf has gravitational potential energy; a moving car has kinetic energy.
学习能量时，用记忆术记住八种能量储存：“Great Kings Eat Magnetic Chocolate Cakes Every Night”（引力势能、动能、弹性势能、磁能、化学能、热能、静电势能、核能）。把每一种储存与现实生活的例子配对：架子上的书具有引力势能；行驶的汽车具有动能。
7. Visual Associations and Diagrams | 视觉联想与图示
Your brain remembers pictures better than words alone. When you learn a new term such as 'diffusion', sketch particles spreading out from a high concentration area to a low concentration area. Add a caption: "Diffusion: particles move until evenly spread." The act of drawing solidifies the meaning.
大脑对图像的记忆比单靠文字更好。当你学习“扩散”这个新术语时，画一个粒子从高浓度区域向低浓度区域扩散的草图。加上说明：“扩散：粒子移动直至均匀分布”。画图的过程能巩固其含义。
For vocabulary about the states of matter, draw three beakers showing solid (particles tightly packed in rows), liquid (particles touching but jumbled) and gas (particles far apart and moving quickly). Label each state, then add arrows with the processes of melting, freezing, boiling and condensing. These visuals act as mental anchor charts.
对于物质状态相关的词汇，画三个烧杯分别展示固体（粒子紧密排列成行）、液体（粒子接触但混杂）和气体（粒子互相远离并快速移动）。标出每种状态，然后加上带有熔化、凝固、沸腾和凝结过程的箭头。这些画面会成为你脑海中的锚定图表。
You can also use colour coding. Highlight all biology terms in green, chemistry terms in blue, and physics terms in red. Over time, your brain starts to associate colours with subjects, speeding up recall during tests.
你还可以使用颜色编码。用绿色突出所有生物学术语，蓝色突出化学术语，红色突出物理术语。久而久之，你的大脑会将颜色与学科关联起来，在测试中加快回忆速度。
8. Flashcards and Spaced Repetition | 闪卡与间隔重复
Flashcards are one of the most effective tools for vocabulary memorisation. Write the English term on one side and the Chinese translation with a short definition on the other. For example, front: "Osmosis", back: "渗透 – movement of water across a semi-permeable membrane." Review them regularly using the Leitner system: cards you find difficult stay in a higher-frequency box, while easy cards move to a box you review less often.
闪卡是记忆词汇最有效的工具之一。一面写上英文术语，另一面写上中文翻译和简短定义。例如，正面：“Osmosis”，反面：“渗透 – 水透过半透膜的移动”。用莱特纳系统定期复习：你觉得难的卡片放在高频复习的盒子里，简单卡片则移到复习频率较低的盒子中。
Spaced repetition fights the forgetting curve. Study a set of new terms, then review after one day, then after three days, then after a week. This pattern moves information from short-term to long-term memory. Apps like Anki or simple paper card boxes work equally well.
间隔重复能对抗遗忘曲线。学习一组新术语，然后一天后复习，三天后再复习，一周后再复习。这种模式能把信息从短期记忆转移到长期记忆。像 Anki 这样的应用程序或简单的纸质卡片盒都很好用。
When creating flashcards, use images or silly associations. For 'exothermic' (releases heat), draw a fire coming out of a test tube. For 'endothermic' (absorbs heat), draw an ice cube taking in warmth. These quirky images make the definitions unforgettable.
制作闪卡时，使用图像或搞笑的联想。对于“exothermic”（放热），画一个试管中喷出火来；对于“endothermic”（吸热），画一个冰块吸收热量。这些古怪的图像会使定义难以忘记。
9. Putting Terms into Sentences and Stories | 将术语融入句子和故事
Using terms in context helps you understand their meaning deeply. Write short stories that include target vocabulary. For example: "The nucleus directed all activities as the cytoplasm buzzed with chemical reactions. Outside, the cell membrane carefully selected which molecules could enter." This not only rehearses the words but also reinforces their functions.
在上下文中使用术语有助于你深刻理解其含义。写一些包含目标词汇的小故事。例如：“细胞核指挥着所有活动，细胞质里化学反应嗡嗡作响。外面，细胞膜仔细地挑选哪些分子可以进入。”这不仅练习了词语，也巩固了它们的功能。
You can also link terms together in a logical chain: "The mitochondria inside muscle cells release energy through respiration, which requires oxygen brought by red blood cells, and produces carbon dioxide as a waste product." Such narratives mirror exam-style explanations and boost your confidence.
你还可以将术语按逻辑串联起来：“肌肉细胞内的线粒体通过呼吸作用释放能量，这需要红细胞带来的氧气，并产生二氧化碳作为废物。”这样的叙述模仿了考试型的解释，增强你的信心。
Challenge yourself to explain a science concept to a friend or family member using only the correct vocabulary. The more you speak the words aloud, the more natural they become. Recording yourself on your phone and listening back is another excellent trick.
挑战自己，用正确的术语向朋友或家人解释一个科学概念。你越经常大声说出这些词，它们就越自然。用手机录下自己的声音再回放，是另一个妙招。
10. Confusing Terms Demystified | 常见易混淆术语辨析
Several pairs of terms are easily mixed up. The table below clarifies some of the most common ones for Year 7 AQA science.
有几对术语很容易混淆。下表澄清了 Year 7 AQA 科学中最常见的几对。
| Term A | Term B | Key Difference (EN) | 关键区别 (CN) |
|---|---|---|---|
| Mass | Weight | Mass is the amount of matter (kg); weight is the force of gravity on that mass (N). | 质量是物质的量（千克），重量是该质量所受的重力（牛顿）。 |
| Element | Compound | Element: one type of atom. Compound: two or more elements bonded together. | 元素：一种原子。化合物：两种或多种不同元素通过化学键结合。 |
| Speed | Velocity | Speed has only magnitude; velocity has direction too. | 速率只有大小；速度既有大小又有方向。 |
| Heat | Temperature | Heat is thermal energy transfer; temperature measures how hot an object is. | 热量是热能的传递；温度衡量物体的冷热程度。 |
| Biotic | Abiotic | Biotic = living factors (plants); Abiotic = non-living factors (sunlight, water). | 生物因素（如植物），非生物因素（如阳光、水）。 |
To remember mass vs. weight, recall that on the Moon your mass stays the same, but your weight is less because gravity is weaker. Thinking about extreme locations helps lock in the concept.
要记住质量与重量，回想一下在月球上你的质量不变，但重量变轻，因为重力更弱。想想极端的场景有助于锁定概念。
11. Interactive Games and Practice | 互动游戏与练习
Games turn revision into fun. Play 'Science Bingo': create bingo cards with vocabulary words; the teacher or a friend reads definitions, and you mark the matching term. Another favourite is 'Taboo', where you must describe a term without using the main forbidden words — this forces you to think about meaning rather than reciting rote definitions.
游戏能把复习变成乐趣。玩“科学宾果”：制作一张有词汇的宾果卡；老师或朋友念出定义，你勾出匹配的术语。另一个受欢迎的玩法是“禁忌词”，你必须描述一个术语，但不能使用被禁止的主要词语——这迫使你思考含义，而不是背诵机械的定义。
Online quizzes on platforms like Quizlet or Kahoot offer instant feedback and a sense of competition. Many sets are already created for AQA KS3 science; you can join live games with classmates. Try beating your own score while revising terms such as 'diffusion' or 'resultant force'.
在 Quizlet 或 Kahoot 等平台上的在线测验提供即时反馈和竞争感。许多针对 AQA KS3 科学的习题集已经建好，你可以和同学一起加入实时游戏。在复习“扩散”或“合力”等术语时，试着打破自己的得分记录。
You can also play 'Word Wall' at home: write each term on a sticky note and slap it on the wall. Every time you walk past, point to one and say its definition aloud. Physical movement combined with speaking locks in memory from multiple angles.
你还可以在家玩“词汇墙”：把每个术语写在便利贴上，贴在墙上。每次路过时，指着一张说出其定义。身体动作加上口头表达能从多个角度锁定记忆。
12. Summary and Final Tips | 总结与最终建议
Mastering Year 7 AQA science vocabulary requires a combination of strategies: break words into roots, use mnemonics, draw diagrams, make flashcards, test yourself with spaced repetition, and play games. Do not try to learn everything the night before a test — short, daily practice sessions are
