Moving from primary science to Year 7 Cambridge Physics is an exciting step. You will begin to look at the world in a more precise, mathematical way, learning core ideas about forces, energy, waves and electricity that explain everything from a falling leaf to a rainbow. This guide helps you bridge the gap smoothly, building confidence and strong foundations for the Cambridge Lower Secondary Science curriculum.

从小学科学升入七年级剑桥物理是激动人心的一步。你将开始用更精确、更数学化的眼光观察世界，学习力、能量、波和电的核心概念，这些概念可以解释从飘落的树叶到彩虹的一切现象。这份指南帮你平稳过渡，建立信心，为剑桥初中科学课程打下坚实基础。

1. Year 7 Cambridge Physics: A New Chapter | 剑桥七年级物理：新篇章

Year 7 marks the start of secondary-level physics within the Cambridge Lower Secondary framework. You will move from general ‘science’ to more distinct subjects, with physics focusing on how objects move, why things fall, how light travels and what energy really means. Lessons combine theory with simple experiments, encouraging you to ask questions and test ideas.

七年级标志着剑桥初中阶段物理学习的开始。你会从笼统的“科学”转向更清晰的学科划分，物理学关注物体如何运动、东西为什么会下落、光如何传播以及能量究竟意味着什么。课程将理论与简单实验相结合，鼓励你提出问题并验证想法。

2. What Is Physics? The Study of Matter and Energy | 什么是物理学？物质与能量的研究

Physics is the branch of science that explores the fundamental rules of the universe. It studies matter – anything that takes up space and has mass – and energy in all its forms. From the tiny particles inside an atom to the motion of planets, physics seeks patterns that can be described with mathematics. In Year 7, you will touch upon forces, motion, energy transfers, sound, light and basic electricity.

物理学是探索宇宙基本规律的科学分支。它研究物质——任何占据空间并具有质量的东西——以及各种形式的能量。从原子内部的微小粒子到行星的运动，物理学寻找可以用数学描述的模式。在七年级，你将接触力、运动、能量传递、声音、光和基础电学。

3. Key Topics Overview | 主要课题概览

The Cambridge Year 7 physics syllabus typically covers four main areas: Forces and Motion, Energy, Waves (including light and sound), and Electricity. You will learn to calculate speed, draw force diagrams, identify forms of energy and build simple circuits. Each topic is linked to real-life contexts, such as how brakes stop a bicycle or why a light bulb glows.

剑桥七年级物理课程通常涵盖四个主要领域：力与运动、能量、波（包括光和声）以及电学。你将学习计算速度、绘制力的示意图、识别能量形式以及搭建简单电路。每个主题都与现实生活相联系，例如刹车如何让自行车停下或灯泡为什么发光。

4. Scientific Inquiry and the Scientific Method | 科学探究与科学方法

Physics is not just about facts; it is about how we find things out. The scientific method involves making observations, asking a question, forming a hypothesis, testing it with a fair experiment, recording data and drawing conclusions. In Year 7, you will design your own investigations, learning to change one variable at a time while keeping others constant.

物理学不仅仅是记住事实，更在于我们如何发现事物。科学方法包括观察、提出问题、做出假设、通过公平实验加以检验、记录数据并得出结论。在七年级，你将设计自己的探究活动，学会每次只改变一个变量而保持其他条件不变。

5. Safety in the Physics Laboratory | 物理实验室安全

Working safely in the lab is the first and most important rule. Always wear safety goggles when handling springs, wires or any equipment that could snap or shatter. Tie back long hair, tuck in loose clothing and listen carefully to your teacher’s instructions. Never run or eat in the lab, and report any breakages immediately. Simple habits prevent accidents.

在实验室安全操作是第一条也是最重要的规则。处理弹簧、导线或任何可能断裂或破碎的设备时，始终佩戴护目镜。扎好长发，束好宽松衣物，仔细听取老师的指导。绝不在实验室奔跑或饮食，任何破损立即报告。简单的习惯可以防止事故发生。

6. Measurement and Units: The Language of Physics | 测量与单位：物理的语言

Physics uses standard units so that scientists everywhere can share results. In Year 7, you will measure length in metres (m), mass in kilograms (kg), time in seconds (s), temperature in degrees Celsius (°C) and force in newtons (N). You will also use prefixes like kilo- (10³), centi- (10⁻²) and milli- (10⁻³) to make numbers more manageable. Accurate measurement is key to reliable experiments.

物理学使用标准单位，以便全球科学家共享结果。在七年级，你将用米（m）测量长度，千克（kg）测量质量，秒（s）测量时间，摄氏度（°C）测量温度，牛顿（N）测量力。你还会用到千（10³）、厘（10⁻²）、毫（10⁻³）等前缀让数字更简洁。精确测量是可靠实验的关键。

7. Forces and Motion: Pushes, Pulls and Speed | 力与运动：推、拉与速度

A force is a push or a pull that can change an object’s shape, speed or direction. Forces are measured in newtons and are often shown with arrows on a diagram. You will learn that balanced forces keep things still or moving at constant speed, while unbalanced forces cause acceleration or deceleration. Speed is calculated as distance divided by time.

力是能改变物体形状、速度或方向的推或拉。力的单位是牛顿，通常在示意图上用箭头表示。你将学到平衡力使物体保持静止或匀速运动，而非平衡力则会引起加速或减速。速度等于距离除以时间。

average speed = total distance ÷ total time

平均速度 = 总距离 ÷ 总时间

8. Energy: Forms, Transfers and Conservation | 能量：形式、传递与守恒

Energy is the ability to do work. It comes in many forms: kinetic (movement), thermal (heat), light, sound, electrical, chemical and gravitational potential. Energy cannot be created or destroyed – it is only transferred or transformed. In Year 7, you will trace energy changes, such as a battery transferring chemical energy into electrical energy to light a lamp.

能量是做功的能力。能量有多种形式：动能（运动）、热能、光能、声能、电能、化学能和重力势能。能量既不能创生也不能消灭——它只会传递或转换。在七年级，你将追踪能量变化，比如电池将化学能转化为电能点亮灯泡。

9. Waves: Light and Sound | 波：光与声

Light and sound are both waves that transfer energy. Light travels in straight lines and can be reflected, refracted and absorbed. You will explore how mirrors work and why objects appear coloured. Sound is produced by vibrations and needs a medium, such as air, to travel. The pitch of a sound depends on its frequency, and its loudness relates to amplitude.

光和声都是传递能量的波。光沿直线传播，可以被反射、折射和吸收。你将探索镜子的工作原理以及物体为何呈现颜色。声音由振动产生，需要空气等介质才能传播。音调取决于频率，响度则与振幅有关。

10. Electricity and Simple Circuits | 电与简单电路

Electricity involves the flow of tiny charged particles called electrons. A simple circuit needs a power source (cell or battery), wires and a component such as a bulb or buzzer. You will learn to draw circuit diagrams using standard symbols and to predict what happens when cells are added or components are arranged in series. Conductors allow electricity to pass; insulators block it.

电涉及被称为电子的微小带电粒子的流动。一个简单电路需要电源（电池）、导线和灯泡或蜂鸣器等元件。你将学习用标准符号绘制电路图，并预测增加电池或将元件串联时会发生什么。导体允许电流通过，绝缘体则阻断电流。

11. Bridging from Primary Science: How to Excel | 从小学科学过渡：如何脱颖而出

In primary school, you learned that things fall down and magnets attract. Now you will explore why, using forces and fields. Secondary physics requires more precise vocabulary, numerical work and logical reasoning. Keep a dedicated notebook, practise drawing diagrams and always write down units. Don’t be afraid to make mistakes – each correction secures a deeper understanding.

在小学，你知道了物体会下落、磁铁会吸引。现在你将用力与场的概念探究为什么。中学物理需要更精确的术语、数值计算和逻辑推理。准备一个专用笔记本，练习画示意图，并始终写下单位。不要害怕犯错——每一次纠正都会加深理解。

12. Tips for Success: Study Skills and Resources | 成功秘诀：学习技巧与资源

Review each lesson within 24 hours to strengthen memory. Use online simulations and videos to visualise abstract ideas, such as electric current or wave motion. Practise past Cambridge checkpoint questions to become familiar with the style. Form study groups to discuss tricky concepts, and keep asking ‘what if?’ – curiosity is the engine of physics.

每次课后24小时内复习以巩固记忆。利用在线模拟和视频将电流或波动等抽象概念可视化。练习以往的剑桥阶段性测试题，熟悉题型。组建学习小组讨论难懂的概念，并不断问“如果……会怎样？”——好奇心是物理学的引擎。
