1. Introduction to Year 7 CIE Physics | 了解 Year 7 CIE 物理
Year 7 CIE Physics is part of the Cambridge Lower Secondary Science curriculum, which also covers Biology and Chemistry. In Physics you will explore energy, forces, waves, electricity, and the structure of matter. The course emphasises hands-on investigation and scientific thinking, preparing you for the IGCSE years ahead.
Year 7 CIE 物理是剑桥初中科学课程的一部分，该课程还包括生物和化学。在物理中，你将探索能量、力、波、电以及物质结构。课程强调动手探究和科学思维，为你未来的 IGCSE 阶段做好准备。
You do not need any prior knowledge of physics equations or complex theories. The summer is a perfect time to look at everyday phenomena with new eyes: why a ball bounces, how a rainbow forms, or why your phone charger gets warm. Building these real-world connections is the best preparation of all.
你不需要预先知道任何物理公式或复杂理论。暑期正是用新眼光观察日常现象的好时机：为什么皮球会弹起、彩虹如何形成、为什么手机充电器会发热。建立这些与现实世界的联系就是最好的准备。
2. Why Physics Matters | 物理为何重要
Physics explains the fundamental rules of nature. From the smallest particles inside an atom to the motion of planets, physics gives us a language to describe and predict what happens. It underpins all of engineering, technology, medicine, and even sports science.
物理诠释了自然界的基本规律。从原子内部的微小粒子到行星的运动，物理为我们提供了一门描述和预测现象的语言。它支撑着所有工程、技术、医学，甚至运动科学。
Studying physics also sharpens your problem-solving skills. Every time you design an experiment, take a measurement, or check whether your result makes sense, you are thinking like a physicist. These habits of mind will help you in all your subjects and in everyday life.
学习物理还能提升你解决问题的能力。每当你设计实验、进行测量或判断结果是否合理时，你都在像物理学家一样思考。这些思维习惯会在所有学科和日常生活中助你一臂之力。
3. Key Skills You'll Develop | 你将发展的关键技能
During Year 7 you will learn much more than facts. You will practise observing carefully, recording data in tables, drawing graphs, and writing conclusions. These practical skills are assessed through regular investigations and are just as important as knowing the theory.
在 Year 7，你要学习的远不止事实性知识。你将练习仔细观察、用表格记录数据、绘制图表并撰写结论。这些实践技能会通过定期开展的探究活动进行评测，与理论知识同等重要。
You will also start using SI units (metres, kilograms, seconds, newtons, joules) confidently. Understanding units and being able to convert between them — for example, kilometres to metres — is a foundational skill that will reappear throughout your physics journey.
你还将开始自信地使用国际单位制（米、千克、秒、牛顿、焦耳）。理解单位并能进行换算——例如千米与米的转换—— 是一项基础技能，会贯穿你整个物理学习过程。
- Observation | 观察: Learn to notice fine details, not just what you expect to see. / 学会注意细节，而非只看到你期望看到的内容。
- Measurement | 测量: Use rulers, stopwatches, thermometers, and ammeters with care. / 仔细使用直尺、秒表、温度计和电流表。
- Data handling | 数据处理: Draw bar charts and line graphs, and spot patterns. / 绘制柱状图和线形图，并发现规律。
- Scientific vocabulary | 科学词汇: Describe observations using accurate terms like 'transparent' or 'acceleration'. / 使用"透明"或"加速度"等准确术语描述观察结果。
4. Core Topics Overview | 核心主题概览
The Year 7 syllabus is divided into several big ideas. Getting a bird's-eye view of these topics before school starts will make your weekly lessons feel more familiar. The table below shows the main areas and a taster of what you will learn.
Year 7 教学大纲分为几大"核心概念"。在开学前对这些主题有一个宏观了解，会让你每周的课堂内容变得更加亲切。下表列出了主要领域以及你即将接触的内容概览。
| Topic | 主题 | What you will explore | 探索内容 |
|---|---|
| Forces and Motion | Balanced/unbalanced forces, speed, distance-time graphs |
| Energy | Forms of energy, conservation, transfer diagrams |
| Waves: Light and Sound | Reflection, refraction, how sound travels, the ear |
| Electricity | Simple circuits, current, voltage, conductors and insulators |
| Magnetism | Magnetic poles, fields, electromagnets |
| The Particle Model | Solids, liquids, gases, changes of state |
| Space Physics (brief) | Day and night, seasons, the Solar System |
5. Forces and Motion | 力与运动
Forces are pushes or pulls that can change how an object moves. In Year 7 you will learn to represent forces with arrows, measure forces in newtons (N) using a forcemeter, and distinguish between contact forces (like friction) and non-contact forces (like gravity).
力是能改变物体运动状态的推或拉。在 Year 7 你将学习用箭头表示力, 用测力计以牛顿 (N) 为单位测量力, 并区分接触力 (如摩擦力) 和非接触力 (如重力)。
When forces on an object are balanced, it stays still or moves at a steady speed. Unbalanced forces cause acceleration, deceleration, or a change in direction. This idea explains why a book rests quietly on a table and why a football speeds up when kicked.
当物体受到的力平衡时, 它会保持静止或匀速运动。不平衡的力则导致加速、减速或方向改变。这个观念解释了为什么书本能静静地放在桌上, 也说明了为什么足球被踢后会加速。
average speed = distance travelled ÷ time taken
平均速度 = 行驶距离 ÷ 所用时间
n 50 seconds, your speed is 100 ÷ 50 = 2 m/s. Remember always to include the correct unit.
暑假期间可以练习用简单数字计算速度。例如, 如果你在 50 秒内走了 100 米, 你的速度就是 100 ÷ 50 = 2 m/s。请务必带上正确的单位。
6. Energy Transfers and Resources | 能量传递与资源
Energy is the ability to do work. It exists in many forms such as kinetic, thermal, light, sound, and chemical energy. The law of conservation of energy states that energy cannot be created or destroyed, only transferred from one store to another.
能量是做功的能力。它以多种形式存在, 如动能、热能、光能、声能和化学能。能量守恒定律指出, 能量既不能被创造也不能被消灭, 只能从一种能量储存转移到另一种。
You will learn to draw energy transfer diagrams. For instance, in a battery-powered torch, chemical energy in the battery is transferred electrically to the bulb, where it becomes light and thermal energy. Such diagrams help you trace energy pathways and recognise that some energy is always dissipated as heat.
你将学习绘制能量传递图。例如，在一个电池供电的手电筒中，电池中的化学能通过电能转移到灯泡，在那里变成光能和热能。这样的示意图能帮你追踪能量路径，并认识到总有一部分能量会以热的形式耗散。
Renewable and non-renewable energy resources are introduced early. Understanding the difference between solar, wind, and fossil fuels sets the stage for later discussions about sustainability and environmental impact.
可再生能源和不可再生能源的概念会早期引入。了解太阳能、风能与化石燃料之间的区别，为日后讨论可持续发展与环境影响奠定基础。
7. Waves: Light and Sound | 波动：光与声
Waves transfer energy without transferring matter. In Year 7, the focus is on light and sound waves. You will investigate how light travels in straight lines, how shadows form, and what happens when light hits a mirror (reflection) or passes through a transparent material (refraction).
波传递能量而不传递物质。在 Year 7，重点是光波和声波。你将探究光如何沿直线传播、影子如何形成，以及光照到镜子时（反射）或穿过透明材料时（折射）会发生什么。
With sound, you will learn that it is produced by vibrations and needs a medium (solid, liquid, or gas) to travel. There is no sound in space because it is a vacuum. You will also discover how the ear detects sound and how pitch and loudness relate to frequency and amplitude.
对于声波，你将知道声音由振动产生，并且需要介质（固体、液体或气体）才能传播。太空中没有声音，因为太空是真空。你还将发现耳朵如何探测声音，以及音调和响度如何与频率和振幅相关。
A simple investigation you can try at home: place a ticking clock on a table, hold your ear against the table top, and then listen from a distance. The sound is louder through the solid wood, showing that sound travels better through solids than through air.
你可以在家尝试一个简单探究：把一只滴答作响的时钟放在桌上，先用耳朵贴着桌面听，然后在远处听。通过固体木头传播的声音更响，这表明声音在固体中传播比在空气中更好。
8. Electricity and Magnetism | 电与磁
Electricity is all about the flow of charge. In Year 7 you will build simple series circuits using cells, wires, bulbs, and switches. You will learn to measure current (in amperes) with an ammeter connected in series, and voltage (in volts) with a voltmeter connected in parallel.
电的核心在于电荷的流动。在 Year 7 你将用电池、导线、灯泡和开关搭建简单的串联电路。你将学习用串联的电流表测量电流（单位：安培），以及用并联的电压表测量电压（单位：伏特）。
Conductors (like copper) allow electricity to pass easily, while insulators (like plastic) do not. Understanding this distinction is vital for safety. Never experiment with mains electricity; all your practical work will use low-voltage cells.
导体（如铜）容易让电流通过，而绝缘体（如塑料）则不能。理解这一区别对安全至关重要。切勿以市电做实验；所有实际操作都会使用低压电池。
Magnetism is a non-contact force. Every magnet has a north and a south pole. Like poles repel, unlike poles attract. You will draw magnetic field lines using a compass and explore how an electromagnet can be made by coiling wire around an iron nail and passing a current through it.
磁力是一种非接触力。每个磁铁都有北极和南极。同极相斥，异极相吸。你将使用指南针绘制磁感线，并探索如何通过将导线绕在铁钉上并通电来制作电磁铁。
9. Practical Work and Safety | 实验操作与安全
Physics is an experimental science. In the school laboratory you will handle equipment like ray boxes, masses, springs, and electrical components. Before doing any practical, your teacher will explain the safety rules: wear goggles when needed, tie back long hair, and never eat or drink in the lab.
物理是一门实验科学。在学校实验室里，你将使用光线盒、砝码、弹簧和电子元件等设备。在任何实验前，老师都会讲解安全规则：必要时佩戴护目镜、扎起长发、实验室中严禁饮食。
ion. Keep your results neat and always write the units. Learning to estimate uncertainties — like saying a length is 5.2 cm ± 0.1 cm — is a bonus skill that will impress your teachers.
你将学习撰写简单的实验报告：目的、预测、方法、结果表格、图表和结论。保持结果整洁，并始终标注单位。学会估算不确定度——例如说某个长度是 5.2 cm ± 0.1 cm——是一项加分技能，会让老师刮目相看。
If you have a garden or a park nearby, try measuring the time a pendulum takes to swing. Use a string, a small weight, and a stopwatch. Change the length of the string and see how the period changes. This is genuine physics research you can do right now.
如果你有花园或附近的公园，可以试着测量单摆的摆动时间。用一根绳子、一个小重物和秒表。改变绳子的长度，观察周期的变化。这正是你现在就能做的真正的物理研究。
10. Building a Study Routine | 建立学习常规
Summer is a wonderful opportunity to develop habits that will serve you all year. Aim for small, regular doses of physics rather than a single cramming session. Reading a science magazine, watching a documentary, or completing one worksheet per week is far more effective than trying to learn everything in the last week of August.
暑假是培养良好学习习惯的绝佳时机，这些习惯会让你全年受益。目标是少量、有规律地接触物理，而非一次性突击。阅读一本科学杂志、观看一部纪录片，或者每周完成一份练习卷，远比八月最后一周试图学完所有内容有效得多。
Set up a 'physics corner' at home. Keep a notebook for jotting down questions that come to mind — why is the sky blue? How does a microwave heat food? — and then research the answers online together with an adult. Curiosity-driven learning sticks better than rote memorisation.
在家中布置一个"物理角"。准备一个笔记本，随时记下脑海中浮现的问题——为什么天空是蓝色的？微波炉如何加热食物？——然后和一位成人一起在网上寻找答案。由好奇心驱动的学习比死记硬背更牢固。
| Week | 周次 | Suggested Activity | 建议活动 |
|---|---|
| 1 | Watch a video on the solar system; draw a labelled diagram. / 观看太阳系视频；绘制标注图解。 |
| 2 | Measure the speed of a toy car across the floor. / 测量玩具车在地板上的速度。 |
| 3 | Build a simple circuit with a battery, bulb, and switch. / 用电池、灯泡和开关搭建简单电路。 |
| 4 | Investigate shadows at different times of the day. / 探究一天中不同时间的影子变化。 |
| 5 | Create a poster showing energy transfers in a hairdryer. / 制作一张海报展示吹风机中的能量传递。 |
| 6 | Review all key words using flashcards. / 使用抽认卡复习所有关键词汇。 |
The goal is not perfection but a gentle introduction. By the time you walk into your first Year 7 physics lesson, you will already have a mental framework into which new knowledge can fit neatly. Enjoy the journey, stay curious, and remember that every great physicist started exactly where you are now.
目标不是完美，而是温和的入门。当你走进第一堂 Year 7 物理课时，你头脑中已经拥有了一个框架，新知识可以自然而然地归位。享受这段旅程，保持好奇心，并且记住：每一位伟大的物理学家都曾站在你此刻的起点上。
