📚 Year 7 CAIE Science: Transition Guide | Year 7 CAIE 科学：升学衔接指南

Welcome to Year 7 Science on the CAIE pathway. Moving up from primary school means you will explore the living world, materials, and forces in greater depth, while also learning how scientists ask questions, design experiments, and interpret data. This guide will help you understand what to expect and how to build confidence for the years ahead.

欢迎来到 CAIE 体系的 Year 7 科学课程。从小学升入初中，你将更深入地探索生命世界、物质和力，同时学习科学家如何提出问题、设计实验和解释数据。本指南将帮助你了解接下来的学习内容，并建立信心，为未来打好基础。

1. Understanding the CAIE Science Curriculum | 了解 CAIE 科学课程

The Cambridge Lower Secondary Science curriculum for Year 7 is organised into four strands: Biology, Chemistry, Physics, and Scientific Enquiry. Each topic is designed to build on what you learned in primary school and to prepare you for the demands of IGCSE science later on.

剑桥初中科学课程在 Year 7 阶段分为四个领域：生物学、化学、物理学和科学探究。每个主题都在你小学知识的基础上加深，让你为日后 IGCSE 科学课程做好准备。

In Biology, you will study cells, the structure of living things, and life processes. Chemistry introduces particles, states of matter, and simple separation techniques. Physics covers forces, energy, and the solar system. Scientific Enquiry runs through all three areas, teaching you how to think and work like a scientist.

在生物部分，你将学习细胞、生物的结构和生命活动；化学部分介绍粒子、物质状态和简单的分离方法；物理部分涵盖力、能量和太阳系。而科学探究贯穿这三个领域，教你像科学家一样思考和动手。

2. Key Scientific Skills for Year 7 | Year 7 关键科学技能

Success in science is not just about remembering facts. You will be expected to observe carefully, classify objects, make predictions, and draw conclusions based on evidence. These skills are practised in every topic.

学好科学不只是记知识点。你需要仔细观察、分类、做出预测，并依据证据得出结论。这些技能会贯穿每个单元的学习。

You will also learn to use scientific vocabulary accurately. Words like ‘hypothesis’, ‘variable’, and ‘reliable’ will become part of your everyday classroom language. Getting comfortable with these terms early on makes later topics much easier to understand.

你还要学会准确地使用科学词汇。“假设”、“变量”、“可靠”等术语将成为课堂常用语。尽早熟悉这些术语，能为以后的学习扫清很多障碍。

3. Laboratory Safety First | 实验室安全第一

Working safely in the laboratory is the most important rule in science. Before you even touch any equipment, you must know the safety symbols and the location of safety equipment such as the fire extinguisher, eye wash station, and first aid kit.

在实验室安全操作是科学课最重要的准则。在接触任何器材之前，你必须认识安全标志，并知道灭火器、洗眼器和急救箱的位置。

Tie back long hair and tuck in loose clothing to avoid catching fire or getting caught in equipment.

长头发要扎起来，宽松的衣物要收紧，以免着火或被设备卷住。
Wear safety goggles whenever you are heating substances or using chemicals, even if the experiment seems simple.

只要加热物质或使用化学品，哪怕看起来很简单，也必须佩戴护目镜。
Never taste any substance in the lab, and do not smell chemicals directly – waft the air above the container towards your nose instead.

切勿品尝实验室中的任何物质；不要直接凑近化学试剂闻气味，应该用手轻轻扇动瓶口上方的空气来闻。
Always listen to your teacher’s instructions before starting an experiment, and report any breakages or spills immediately.

实验开始前一定要听清老师的指导，如有破损或洒漏，要立刻报告。

4. Biology: Cells and Life Processes | 生物：细胞与生命活动

In Year 7, you will discover that all living things are made of cells. You will learn to identify the parts of a typical animal cell (nucleus, cytoplasm, cell membrane) and a plant cell (adding cell wall, chloroplasts, and a large vacuole).

在 Year 7，你将认识到所有生物都由细胞构成。你将学会识别典型动物细胞（细胞核、细胞质、细胞膜）和植物细胞（多了细胞壁、叶绿体和大液泡）的结构。

You will also explore the seven life processes, often remembered by the acronym MRS GREN: Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, and Nutrition. Understanding these processes helps you classify living things and study how they survive.

你还会学习生命活动的七大过程，常记为 MRS GREN：运动、呼吸作用、感应性、生长、繁殖、排泄和营养。理解这些过程有助于你为生物分类，并研究它们的生存方式。

Plant cell: contains chloroplasts for photosynthesis → CO₂ + H₂O → glucose + O₂

植物细胞：含有叶绿体进行光合作用 → CO₂ + H₂O → 葡萄糖 + O₂

5. Chemistry: Particles and Mixtures | 化学：粒子与混合物

You will learn that everything around you is made of tiny particles that move and arrange themselves differently in solids, liquids, and gases. This particle model explains why ice floats, why perfume spreads across a room, and why you can compress air but not water.

你会学到，你周围的一切都由微小的粒子构成，这些粒子在固态、液态和气态中的运动方式和排列方式不同。这个粒子模型能解释为什么冰会浮在水上、香水如何在房间里扩散，以及为什么你能压缩空气却很难压缩水。

Another key Year 7 topic is mixtures. You will use techniques such as filtration, evaporation, and distillation to separate substances. These practical activities show you how scientists obtain pure substances and are great for developing your lab skills.

Year 7 的另一个关键主题是混合物。你将使用过滤、蒸发和蒸馏等技术来分离物质。这些实践活动既让你看到科学家如何获得纯净物质，又能很好地锻炼你的实验能力。

Diffusion: particles spread from a region of high concentration to low concentration

扩散：粒子从高浓度区域向低浓度区域扩散

6. Physics: Forces and Motion | 物理：力与运动

Forces are pushes or pulls that can change an object’s speed, shape, or direction. In Year 7, you will measure forces using a newton meter and learn to draw force arrows on diagrams to show balanced and unbalanced situations.

力是能让物体改变速度、形状或方向的推或拉。在 Year 7，你将使用弹簧秤测量力的大小，并学习在示意图上用力箭头表示平衡和不平衡的状态。

You will also explore how speed is calculated and how simple levers and pulleys can make work easier. Practical tasks might include investigating friction on different surfaces or measuring how the extension of a spring depends on the force applied.

你还会学习如何计算速度，以及简单的杠杆和滑轮如何让工作更省力。实践活动可能包括研究不同表面的摩擦力，或测量弹簧的伸长量如何随外力变化。

weight = mass × gravitational field strength → W = m × g

重量 = 质量 × 重力场强度 → W = m × g

7. Scientific Enquiry and Variables | 科学探究与变量

Scientific enquiry is all about finding answers to questions through experiments. Before you start any test, you need to identify the independent variable (the thing you change), the dependent variable (the thing you measure), and control variables (things you keep the same).

科学探究就是通过实验寻找答案。在开始任何测试之前，你需要确定自变量（你改变的因素）、因变量（你测量的结果）和控制变量（保持不变的因素）。

You will practise writing a clear hypothesis, such as ‘If the amount of light increases, then the rate of photosynthesis will increase.’ Recording results in a table and drawing graphs help you spot patterns and evaluate whether your data supports the prediction.

你将练习写出清晰的假设，例如“如果光照量增加，那么光合作用的速率会增加”。把结果记录在表格中，并绘制图表，有助于发现规律，并评估数据是否支持你的预测。

8. Data Handling and Graphs | 数据处理与图表

Being able to present and interpret data is a vital science skill. In Year 7 you will draw bar charts for categorical data and line graphs for continuous measurements, making sure to label axes, choose a sensible scale, and add a title.

能展示和解读数据是一项重要的科学技能。在 Year 7，你需要为分类数据绘制条形图，为连续测量数据绘制线图，并确保标出坐标轴、选择合适的刻度、添加标题。

You will also learn to identify anomalous results and discuss the reliability of your investigation. This often leads to asking ‘What could I do to make my results more repeatable?’ – a question every good scientist should ask.

你还会学习识别异常结果，并讨论实验的可靠性。这经常会引出这样的问题：“我该怎样做才能让结果更具可重复性？”——每个优秀科学家都该这么问。

9. Studying Effectively for Science | 高效学习科学

Because Year 7 Science covers three different subjects, it helps to organise your notes with clear headings, labelled diagrams, and summaries. Try making flash cards for new vocabulary and mind maps to link big ideas like ‘energy’ across Biology, Chemistry, and Physics.

Year 7 科学涵盖三门学科，做笔记时用清晰的标题、标注插图和总结会很有帮助。试着为生词制作抽认卡，并用思维导图将“能量”这类大概念在生物、化学和物理中联系起来。

After each lesson, take five minutes to write one thing you understood well and one question you still have. This simple habit makes revision far easier when assessments approach, and it trains you to be an active learner instead of a passive listener.

每节课后花五分钟写下你理解透彻的一个知识点，以及你仍有的一个疑问。这个简单的习惯会让考前复习轻松很多，也能训练你成为主动的学习者，而不是被动的听众。

10. Exciting Real-World Connections | 激动人心的现实世界联系

Science is not just in the textbook. The concepts you learn in Year 7 explain the colours of a rainbow, why bread rises, how a bicycle brake works, and what keeps the planets orbiting the Sun. Looking for science in everyday life makes the subject far more memorable and enjoyable.

科学不止在课本里。Year 7 学到的概念可以解释彩虹的颜色、面包为什么会膨胀、自行车刹车如何工作，以及是什么让行星围绕太阳运转。在日常生活中寻找科学的影子，会让这门课变得更难忘记，也更有趣。

To prepare for your next step, try watching short documentary clips, asking ‘why’ when you see something unusual, and keeping a curiosity journal. These small actions build the critical thinking skills that CAIE assessments reward right up to IGCSE and beyond.

为了更好地为下一阶段做准备，可以看看短纪录片、遇到不寻常的事多问一个“为什么”，并坚持写一本好奇心日记。这些小小的举动能培养批判性思维能力，这也是 CAIE 考试一直到 IGCSE 甚至更高阶段都看重的能力。
