1. Understanding the CAIE Lower Secondary Science Curriculum | 理解 CAIE 初中科学课程

The Cambridge Lower Secondary Science curriculum for Year 7 is designed to build a solid foundation of scientific knowledge and skills. It focuses on four strands: Biology, Chemistry, Physics and Scientific Enquiry. Each strand is taught through inquiry-based learning, encouraging students to think like scientists. The curriculum is flexible and can be adapted to different school contexts, but core learning objectives remain consistent globally.

剑桥初中科学课程（Year 7）旨在为科学知识和技能打下坚实基础。它侧重于四个部分：生物学、化学、物理学和科学探究。每个部分都通过探究式学习来教授，鼓励学生像科学家一样思考。该课程灵活，可适应不同的学校环境，但核心学习目标在全球范围内保持一致。

Assessment typically includes continuous evaluation of classwork, practical investigations and end-of-unit tests. Parents should familiarise themselves with the learning objectives for each term, often available in school curriculum handbooks or online. Understanding the “big ideas” behind each topic helps you link homework to real-world applications.

评估通常包括课堂作业、实践调查和单元结束测试的持续评价。家长应该熟悉每个学期的学习目标，这些通常可以在学校课程手册或网上找到。理解每个主题背后的 “大概念” 有助于您将家庭作业与现实世界应用联系起来。

2. Key Topics in Year 7 Science | Year 7 科学的关键主题

Year 7 science covers a broad range of introductory topics. In Biology, your child will learn about cells, classification of living things, plant structures and human body systems. Chemistry introduces the particle model, states of matter, properties of materials and simple chemical reactions. Physics explores forces, motion, energy, sound and light. Scientific enquiry runs through all topics, emphasising hypothesis, variables, data collection and drawing conclusions.

Year 7 科学涵盖了一系列入门主题。在生物学方面，您的孩子将学习细胞、生物分类、植物结构和人体系统。化学则引入粒子模型、物质状态、材料性质和简单的化学反应。物理学探讨力、运动、能量、声音和光。科学探究贯穿所有主题，强调假设、变量、数据收集和得出结论。

These topics are linked together by cross-cutting concepts such as energy transfer, patterns and systems. You can support learning by pointing out connections, for example how the particle model explains both changes of state in chemistry and diffusion in biology.

这些主题由跨学科概念（如能量转移、模式和系统）串联起来。您可以通过指出联系来支持学习，例如粒子模型如何解释化学中的状态变化和生物学中的扩散。

A typical Year 7 science textbook or syllabus will sequence these topics to build progressively. Common CAIE-endorsed resources include the Cambridge Lower Secondary Science series. Check with your child’s school for the exact scheme of work.

一本典型的 Year 7 科学教科书或教学大纲会按顺序安排这些主题，以逐步构建。常见的剑桥认可资源包括剑桥初中科学系列。请向您孩子的学校查询确切的教学计划。

3. Biology Focus: Cells, Plants and Human Systems | 生物重点：细胞、植物和人体系统

Biology in Year 7 starts with the cell as the basic unit of life. Students learn to identify and label parts of plant and animal cells (nucleus, cytoplasm, cell membrane, cell wall, chloroplasts) using a light microscope. They also explore the hierarchy from cells to tissues, organs and organ systems. Key systems covered include the digestive system, circulatory system and respiratory system.

Year 7 的生物从细胞作为生命的基本单位开始。学生学会使用光学显微镜识别和标注植物和动物细胞的各个部分（细胞核、细胞质、细胞膜、细胞壁、叶绿体）。他们还探索从细胞到组织、器官和器官系统的层次结构。涵盖的关键系统包括消化系统、循环系统和呼吸系统。

• Help your child draw and label diagrams of cells, then explain functions in simple terms.

  帮助您的孩子绘制并标注细胞图，然后用简单的语言解释功能。

• Use analogies, such as comparing the cell to a factory where the nucleus is the control centre.

  使用类比，比如将细胞比作工厂，细胞核是控制中心。

Plant topics include photosynthesis and how plants make food. A simple equation can be memorised: carbon dioxide + water → glucose + oxygen, in the presence of light and chlorophyll. Emphasise the role of leaves, stomata and roots.

植物主题包括光合作用以及植物如何制造食物。一个简单方程可记：二氧化碳 + 水 → 葡萄糖 + 氧气，在光和叶绿素存在下。强调叶、气孔和根的作用。

Human systems are often taught through diagrams and simple experiments, like measuring pulse rate before and after exercise. Encourage your child to trace the path of food through the digestive system and explain the role of enzymes briefly.

人体系统通常通过图表和简单实验教授，例如测量运动前后的脉搏率。鼓励您的孩子追踪食物通过消化系统的路径，并简要解释酶的作用。

4. Chemistry Focus: States of Matter and Chemical Reactions | 化学重点：物质的状态和化学反应

Chemistry in Year 7 builds on the particle model, explaining properties of solids, liquids and gases. Students learn to describe changes of state (melting, freezing, boiling, condensation, sublimation) in terms of energy and particle arrangement. The concept of diffusion is introduced, often using potassium permanganate in water or perfume in air.

Year 7 的化学以粒子模型为基础，解释固体、液体和气体的性质。学生学会用能量和粒子排列来描述状态变化（熔化、凝固、沸腾、凝结、升华）。还引入扩散概念，常用高锰酸钾在水中或香水在空气中演示。

• Practical at home: Melt an ice cube and discuss particle movement. Boil water and observe condensation.

  在家实践：融化一块冰并讨论粒子运动。烧水并观察凝结现象。

• Use marbles or balls to model solid, liquid and gas particles.

  用弹珠或小球来模拟固体、液体和气体粒子。

Simple chemical reactions are explored, such as burning magnesium, reacting vinegar with bicarbonate of soda, or rusting of iron. Students learn to identify reactants and products, and to recognise evidence of a chemical change: colour change, temperature change, gas production, precipitate formation.

还探讨简单的化学反应，例如镁燃烧、醋与小苏打反应，或铁生锈。学生学习识别反应物和产物，并认识化学变化的证据：颜色变化、温度变化、产生气体、生成沉淀。

Writing word equations is a key skill. Support your child in practising these, e.g., magnesium + oxygen → magnesium oxide. Ensure they understand that mass is conserved, though a full treatment of balancing equations comes later.

书写文字方程式是一项关键技能。支持您的孩子练习这些，例如：镁 + 氧气 → 氧化镁。确保他们理解质量守恒，尽管完整的化学方程式配平稍后才会涉及。

5. Physics Focus: Forces, Energy and Waves | 物理重点：力、能量和波

Year 7 physics introduces the concept of forces as pushes or pulls, measured in newtons (N). Students learn about balanced and unbalanced forces, friction, gravity and air resistance. They may investigate how the extension of a spring is related to the force applied (Hooke’s Law qualitative). Calculating speed using the formula speed = distance ÷ time is common.

Year 7 物理引入了力作为推或拉的概念，以牛顿 (N) 为单位。学生学习平衡力与不平衡力、摩擦力、重力和空气阻力。他们可能会研究弹簧的伸长与所施加的力的关系（胡克定律定性）。使用公式 速度 = 距离 ÷ 时间 计算速度是常见内容。

Energy is discussed in terms of different forms (kinetic, thermal, light, sound, electrical, chemical) and energy transfers. The principle of conservation of energy is introduced simply. Sound and light are treated as waves: sound waves need a medium, travel at different speeds, and are related to pitch and loudness. Light waves are explored through reflection, refraction (qualitative) and the visible spectrum.

能量以不同形式（动能、热能、光能、声能、电能、化学能）和能量转移来讨论。简单介绍了能量守恒原理。声音和光被视作波：声波需要介质，以不同速度传播，与音调和响度相关。光波通过反射、折射（定性）和可见光谱来探索。

• Use a slinky or rope to demonstrate transverse and longitudinal waves.

  使用弹簧玩具或绳子演示横波和纵波。

• Create a simple circuit at home with a battery, bulb and wires to show electrical energy transfer.

  在家用电池、灯泡和导线制作简单电路，展示电能转移。

Encourage your child to draw labelled ray diagrams for reflection and explain why we see colours.

鼓励您的孩子为反射画标注的射线图，并解释为什么我们看到颜色。
