📚 Year 7 Cambridge Science: Vocabulary Memorisation Guide | Year 7 剑桥科学：词汇术语速记指南

Mastering scientific terminology in Year 7 is like learning the alphabet of the natural world. The Cambridge Lower Secondary Science syllabus requires you to understand key words and use them confidently in explanations. This guide breaks down essential terms into clear definitions, simple memory hooks and visual tricks so that you can recall them quickly during lessons and tests.

在 Year 7 掌握科学术语就像学习自然界的字母表。剑桥初中科学大纲要求你理解关键词汇，并能在解释中自信地使用它们。本指南将核心术语拆解为清晰的定义、简单的记忆挂钩和图像化诀窍，让你在课堂和测验中都能快速回想。

1. Cells and Tissues | 细胞与组织

The journey into biology starts with the cell, the tiniest living unit. Knowing these core words will help you discuss everything from bacteria to blue whales.

生物学之旅从细胞这个最微小的生命单位开始。掌握这些核心词汇，你就能讨论从细菌到蓝鲸的一切。

Cell: Picture a tiny prison ‘cell’ – a small, enclosed space that holds a prisoner. Our living cell is a tiny enclosed unit that keeps life processes inside. Saying ‘cell = small room of life’ locks the image in your mind.

细胞：想象一个微小的监狱“牢房”（cell）——一个关押囚犯的封闭空间。我们活的细胞正是一个微小的封闭单元，将生命过程保存在里面。默念“细胞 = 生命的小牢房”就能把这幅画面锁进脑海。

Nucleus: The word sounds like ‘nuclear’ or ‘core’. Think of the nucleus as the brain of the cell, giving instructions. The memory phrase ‘NUcleus = NUmbER one organelle’ reminds you it is the most important part.

细胞核：这个词听起来像“核”或“核心”。把细胞核想象成细胞的大脑，发号施令。记忆口诀“核 = 核心首脑”就能提醒你它是头号重要的结构。

Cytoplasm: Break it into ‘cyto-‘ (cell) and ‘-plasm’ (jelly). Visualise a colourful fruit jelly with fruit pieces floating inside – the jelly is the cytoplasm and the fruit chunks are the organelles.

细胞质：把它拆成“cyto-”（细胞）和“-plasm”（浆状物）。想象一盒彩色果冻，里面的水果粒就是细胞器，包裹它们的果冻就是细胞质。

Cell membrane: Imagine a strict gatekeeper at a castle: only food and messages can enter, only waste can leave. The membrane is a ‘member-gate’ – only approved members may pass.

细胞膜：想象城堡门口的严厉守卫：只有食物和信号能进入，只有废物能出去。细胞膜就像一道“成员门禁”——只有获批的成员才可通过。

Tissue: A tissue paper is made of many intertwined fibres. Similarly, biological tissue is woven from many similar cells. When muscle cells team up, they form muscle tissue to pull on bones.

组织：一张纸巾（tissue）由许多交错纤维组成。同样地，生物组织也是由许多同类细胞“编织”而成。当肌肉细胞联合起来，就形成了拉动骨骼的肌肉组织。

2. Particle Theory and States of Matter | 粒子理论与物质状态

Everything around us is made of tiny particles, and how they are arranged decides whether a substance is solid, liquid or gas. These terms form the backbone of chemistry.

我们身边的一切都由微小粒子构成，粒子的排列方式决定了物质是固体、液体还是气体。这些术语构成了化学的骨架。

Particle: Think of ‘part’ – a particle is a small part of a whole. Everything is made of these invisible dots. The word ‘particle’ itself contains ‘part’, helping you remember it is a tiny bit.

粒子：想想“部分（part）”——粒子就是整体中极小的一部分。万物都由这些肉眼看不见的小点构成。“particle”这个词本身含有“part”，帮你记住它是一个微小份额。

Solid: Imagine soldiers standing to attention – they are tightly packed and cannot move past each other. ‘Solid as a rock’ helps you recall that the shape does not change.

固体：想象士兵立正站好——他们紧紧挤在一起，无法穿过彼此身旁。“坚如磐石”帮你记住形状保持不变。

Liquid: Picture a crowded dance floor where people stay close but can slip and slide around each other. The liquid takes the shape of the dance floor (the container).

液体：想象一个拥挤的舞池，人们靠得很近，却能相互滑动穿梭。液体就像舞池里的人，随着舞池的边界（容器）变换形状。

Gas: Think of children released onto a playground – they run everywhere, filling the whole space. A gas expands to fill any container because the particles zoom about freely.

气体：想象一群孩子被放到操场上——他们四散奔跑，占满整个空间。气体之所以能充满任何容器，正是因为粒子在无拘无束地飞窜。

Diffusion: Picture a drop of ink spreading in water. The particles travel from where they are crowded (high concentration) to where they are sparse. ‘Diffusion = Different distribution’ can help you connect the word.

扩散：想象一滴墨
