1. Curriculum Overview | 课程总览
The Year 7 AQA Physics course is part of the broader AQA KS3 Science programme. It builds on knowledge from primary school and introduces foundational concepts that will be developed further in Years 8 and 9. The curriculum is structured around the ‘Big Ideas’ in science: Forces, Electromagnetism, Energy, and Waves.
七年级AQA物理课程是更广泛的AQA KS3科学课程的一部分。它建立在小学知识的基础上，并引入一些基础概念，这些概念将在八年级和九年级进一步深化。课程围绕科学中的“大概念”展开：力、电磁、能量和波。
You will have three to four physics lessons per fortnight, often combined with chemistry and biology topics within a thematic unit. Assessment includes end-of-topic tests, practical write-ups, and ongoing teacher observation. The focus is on understanding how the physical world works and developing scientific thinking.
你每两周会有三到四节物理课，通常与化学和生物主题结合在同一个主题单元中。评估包括单元结束测试、实验报告撰写和教师的持续观察。重点是理解物理世界是如何运作的，并培养科学思维。
2. Energy: Stores and Transfers | 能量：存储与转移
Energy is the ability to do work and is measured in joules (J). Even in Year 7, we begin by learning that energy cannot be created or destroyed; it can only be transferred or stored. This is the principle of conservation of energy.
能量是做功的能力，以焦耳（J）为单位。在七年级，我们首先学习能量不能被创造或消灭，它只能被转移或储存。这就是能量守恒原理。
The eight main energy stores are: kinetic (movement), gravitational potential (height), chemical (food and fuels), elastic potential (stretched or compressed objects), thermal (heat), magnetic, electrostatic (electric charges), and nuclear.
八种主要能量存储方式是：动能（运动）、重力势能（高度）、化学能（食物和燃料）、弹性势能（拉伸或压缩的物体）、热能（热）、磁能、静电势能（电荷）和核能。
Energy is transferred between stores via four pathways: mechanically (by a force doing work), electrically (by an electric current), by heating (due to a temperature difference), and by radiation (such as light or sound).
能量通过四种途径在存储方式之间转移：机械做功（力做功）、电做功（电流）、加热（由于温差）和辐射（如光或声）。
Eₖ = ½ m v² | Eg = m g h
tial energy depends on mass, height and gravitational field strength (g ≈ 10 N/kg on Earth).
在七年级你可能还不需要进行这些计算，但你应该知道动能取决于质量和速度，而重力势能取决于质量、高度和重力场强（地球上 g ≈ 10 N/kg）。
Renewable resources like solar, wind, and tidal are compared with non-renewables such as coal, oil, and gas. You will discuss advantages and disadvantages, linking to real-world electricity generation.
太阳能、风能、潮汐能等可再生资源会与煤、石油、天然气等不可再生资源进行比较。你将讨论它们的优缺点，并与真实世界的发电方式联系起来。
3. Forces: Types and Measurement | 力：类型与测量
A force is a push or a pull that acts on an object. The unit of force is the newton (N). Forces are vector quantities, so they have both magnitude and direction. They can change the shape, speed, or direction of an object.
力是作用在物体上的推或拉。力的单位是牛顿（N）。力是矢量，所以它们既有大小也有方向。力可以改变物体的形状、速度或方向。
Forces are classified as contact forces (friction, air resistance, tension, normal contact) or non-contact forces (gravity, magnetism, electrostatic force). Friction opposes motion and often produces heat.
力分为接触力（摩擦力、空气阻力、张力、法向接触力）和非接触力（重力、磁力、静电力）。摩擦力阻碍运动，通常会产生热量。
You will use a newton meter to measure forces. Drawing force diagrams with arrows is a key skill; the length of the arrow represents the magnitude, and the arrowhead points in the direction of the force.
你将使用弹簧测力计来测量力。绘制带有箭头的力图是一项关键技能；箭头的长度表示大小，箭头指向力的方向。
Balanced forces produce no change in motion, while unbalanced forces cause acceleration or deceleration. This links directly to the idea of resultant force.
平衡力不会改变运动状态，而非平衡力则会导致加速或减速。这与合力的概念直接相关。
4. Motion and Speed | 运动与速度
tance ÷ time. The typical units are metres per second (m/s) or kilometres per hour (km/h).
速度告诉我们物体运动的快慢。平均速度用公式计算：速度 = 距离 ÷ 时间。典型单位是米每秒（m/s）或公里每小时（km/h）。
v = d / t
ractical involves timing a toy car over a measured distance and plotting a simple distance–time graph.
你将学习变形这个公式来求距离（d = v × t）或时间（t = d / v）。一个常见的实验是测量玩具车行驶一定距离的时间，并绘制简单的距离-时间图。
On a distance–time graph, a steeper slope indicates a higher speed. A horizontal line means the object is stationary. You must be able to describe motion using terms like stationary, constant speed, accelerating, and decelerating.
在距离-时间图上，较陡的斜率表示较高的速度。水平线表示物体静止。你必须能够使用静止、匀速、加速和减速等术语来描述运动。
Gravity near the Earth’s surface produces an acceleration of about 10 m/s². This means that for every second an object falls, its speed increases by about 10 m/s (ignoring air resistance).
地球表面附近的重力产生大约 10 m/s² 的加速度。这意味着物体每下落一秒，其速度就增加大约 10 m/s（忽略空气阻力）。
5. Electric Circuits and Current | 电路与电流
An electric current is a flow of electric charge, usually carried by electrons moving through a wire. Current is measured in amperes (A) using an ammeter connected in series. For a current to flow, the circuit must be complete and contain a source of potential difference.
电流是电荷的流动，通常由电子在导线中移动形成。电流以安培（A）为单位，使用串联在电路中的电流表测量。要使电流流动，电路必须是完整的，并且包含一个电势差源。
In Year 7, we build simple circuits using cells, bulbs, buzzers, and motors. You must be able to draw circuit diagrams using standard symbols. The international symbol for a cell is a long line and a short line; a battery is two or more cells.
在七年级，我们使用电池、灯泡、蜂鸣器和电机构建简单电路。你必须能够使用标准符号画出电路图。单个电池的国际符号是一长一短两条线；电池组则是两个或多个电池。
There are two types of circuit: series and parallel. In a series circuit, components are connected one after another, so there is only one path for the current. If one component breaks, the whole circuit stops working.
电路有两种类型：串联和并联。在串联电路中，元件一个接一个地连接，因此电流只有一条路径。如果一个元件损坏，整个电路都会停止工作。
In a parallel circuit, components are connected on separate branches. This means the current can take multiple paths, so if one bulb breaks, the others can stay on. This is how household lighting is wired.
在并联电路中，元件连接在不同的支路上。这意味着电流可以走多条路径，所以如果一个灯泡坏了，其他灯泡仍然可以亮。家用照明就是按照这种方式接线的。
6. Voltage and Resistance | 电压与电阻
Voltage (or potential difference) is the force that pushes electrons around a circuit. It is measured in volts (V) using a voltmeter connected in parallel. A higher voltage means a stronger push on the charges.
电压（或电势差）是推动电子在电路中流动的力量。它以伏特（V）为单位，使用并联的电压表测量。电压越高，对电荷的推动力就越强。
Resistance is anything that slows down the flow of current. It is measured in ohms (Ω). Wires have low resistance, but components like bulbs and resistors have higher resistance, converting electrical energy into light or heat.
电阻是任何阻碍电流流动的因素。它以欧姆（Ω）为单位。导线的电阻很低，但像灯泡和电阻器这样的元件具有较高的电阻，会将电能转化为光或热。
You will carry out investigations to see how changing the number of cells or the type of component affects the current in a circuit. A simple model often used is a water pipe: voltage is like water pressure, current is like the flow rate, and resistance is like a narrowing in the pipe.
你将通过实验研究改变电池数量或元件类型如何影响电路中的电流。一个常用的简单模型是水管模型：电压好比水压，电流好比流速，电阻好比管道中的狭窄处。
In a series circuit, the current is the same everywhere, but the voltage is shared across components. In a parallel circuit, the voltage across each branch is the same as the source voltage, but the current is divided between branches.
在串联电路中，电流处处相等，但电压被各元件分摊。在并联电路中，每条支路两端的电压与电源电压相同，但电流在各支路之间分配。
7. Sound Waves | 声波
Sound is a longitudinal wave that travels as a vibration through a medium, such as air, water, or solids. It cannot travel through a vacuum because there are no particles to pass on the vibrations. The speed of sound in air is about 340 m/s.
声音是一种纵波，它以振动的形式通过空气、水或固体等介质传播。声音不能在真空中传播，因为没有粒子来传递振动。声音在空气中的速度约为 340 m/s。
The pitch of a sound depends on the frequency of the vibration: a higher frequency gives a higher pitch. Loudness depends on the amplitude of the wave; a larger amplitude carries more energy and sounds louder.
声音的音调取决于振动的频率：频率越高，音调越高。响度取决于波的振幅：振幅越大，携带的能量越多，听起来越响。
You will investigate sound using tuning forks, oscilloscopes, and musical instruments. An oscilloscope trace shows a waveform where the number of waves per second is the frequency (measured in hertz, Hz).
你将使用音叉、示波器和乐器研究声音。示波器迹线显示波形，每秒的波数就是频率（以赫兹 Hz 为单位）。
The human ear detects sound from about 20 Hz to 20,000 Hz. Ultrasound is sound above this range and has uses in medical scanning and sonar. You should know that loud sounds can damage hearing and that protection is important.
人耳可以听到大约 20 Hz 到 20,000 Hz 的声音。超声波是高于此范围的声音，在医学扫描和声呐中有应用。你应该知道过大的声音会损害听力，保护措施很重要。
8. Light and Optics | 光与光学
Light is a transverse wave that does not need a medium to travel; it can move through a vacuum at 300,000 km/s. Light from a source travels in straight lines, which explains why shadows are formed. Shadows show that light is blocked by opaque objects.
光是一种横波，不需要介质就能传播；它可以在真空中以 300,000 km/s 的速度移动。来自光源的光沿直线传播，这就解释了影子是如何形成的。影子表明光被不透明物体阻挡。
Reflection is the bouncing of light off a surface. The law of reflection states that the angle of incidence equals the angle of reflection, both measured from the normal (a line at 90° to the surface). You will use plane mirrors and ray boxes to verify this.
反射是光线从表面反弹。反射定律指出，入射角等于反射角，两者都是从法线（与表面成 90° 的线）开始测量的。你将使用平面镜和光线箱来验证这一定律。
Refraction is the bending of light as it passes from one medium to another (e.g., from air to glass), caused by a change in speed. A lens uses refraction to converge or diverge light rays. The eye contains a lens that focuses light onto the retina.
折射是光从一种介质进入另一种介质（例如从空气到玻璃）时由于速度改变而发生的弯曲。透镜利用折射来会聚或发散光线。眼睛包含一个将光聚焦到视网膜上的晶状体。
White light is actually a mixture of all the colours of the visible spectrum. A prism can separate white light into red, orange, yellow, green, blue, indigo, and violet. Coloured objects appear the way they do because they reflect certain colours and absorb others.
白光实际上是所有可见光谱颜色的混合。棱镜可以将白光分解为红、橙、黄、绿、蓝、靛、紫。彩色物体之所以呈现某种颜色，是因为它们反射某些颜色的光而吸收其他颜色。
9. The Solar System and Space | 太阳系与宇宙
Our solar system consists of the Sun (a star), eight planets, dwarf planets, moons, asteroids, and comets. The planets in order from the Sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Gravity keeps them in orbit.
我们的太阳系由太阳（一颗恒星）、八大行星、矮行星、卫星、小行星和彗星组成。按距离太阳由近到远的顺序，行星依次是：水星、金星、地球、火星、木星、土星、天王星、海王星。引力使它们保持在轨道上运行。
The Earth rotates on its axis once every 24 hours, giving us day and night. The Earth’s axis is tilted, which causes the seasons as we orbit the Sun over one year. When the northern hemisphere is tilted towards the Sun, it experiences summer.
地球每 24 小时自转一周，产生昼夜。地轴是倾斜的，这导致我们绕太阳公转一年中出现四季变化。当北半球朝向太阳倾斜时，那里就是夏季。
The Moon orbits the Earth approximately every 28 days. Its changing appearance – the phases – is due to the relative positions of the Sun, Earth, and Moon. A solar eclipse happens when the Moon passes directly between the Earth and the Sun.
月球大约每 28 天绕地球一周。它变化的外观——月相——是由太阳、地球和月球的相对位置造成的。当月球直接经过地球和太阳之间时，就会发生日食。
Beyond our solar system, the universe is vast. Stars give out light because of nuclear reactions in their cores. Many stars have their own planetary systems. We use telescopes and space probes to explore further.
在太阳系之外，宇宙是浩瀚的。恒星因其核心的核反应而发光。许多恒星都有自己的行星系统。我们使用望远镜和太空探测器进行更深入的探索。
10. Scientific Enquiry and Practical Skills | 科学探究与实验技能
Physics is an experimental science, and Year 7 is when you start using the scientific method in a structured way. You will learn to make hypotheses, identify variables (independent, dependent, control), and design fair tests.
物理是一门实验科学，七年级是你开始有条理地使用科学方法的时期。你将学习提出假设，识别变量（自变量、因变量、控制变量），并设计公平实验。
Recording data accurately in tables and plotting graphs are essential skills. You must label axes with quantities and units, choose sensible scales, and draw lines of best fit. In physics, we often look for patterns like ‘the current increases as the voltage increases’.
在表格中准确记录数据并绘制图形是基本技能。你必须用物理量和单位标记坐标轴，选择合适的刻度，并画出最佳拟合线。在物理中，我们经常寻找诸如“电流随电压增加而增大”这样的规律。
Safety is prioritised: you will wear goggles when heating or using glass, handle electrical equipment with care, and always follow instructions. Risk assessments help you identify hazards and decide on precautions.
安全是首要任务：在加热或使用玻璃器皿时要戴护目镜，小心操作电气设备，并始终遵守指示。风险评估帮助你识别危险并确定预防措施。
Common practicals include measuring the speed of a toy car, stretching a spring to investigate Hooke’s Law, building series and parallel circuits, and investigating reflection using ray boxes. Each practical will involve a write-up with an aim, method, results, and conclusion.
常见的实验包括测量玩具车的速度、拉伸弹簧以探究胡克定律、搭建串联和并联电路，以及使用光线箱研究反射。每个实验都需要撰写报告，包括目的、方法、结果和结论。
11. Assessment and Progression | 评估与进阶
Assessment in Year 7 AQA Physics is continuous and varied. You will have topic tests at the end of each unit, containing multiple-choice, short-answer, and extended writing questions. Practical skills may be assessed through observation or a specific investigation task.
七年级AQA物理的评估是持续且多样的。每个单元结束时有主题测试，包含选择题、简答题和拓展写作题。实验技能可以通过观察或特定的探究任务进行评估。
Your teacher will use the AQA KS3 grid to track your progress against ‘I can’ statements. These describe what you should be able to do, such as ‘I can describe how sound travels’ or ‘I can draw a series circuit diagram’.
你的老师将使用AQA KS3网格，对照“我能”陈述来跟踪你的进步。这些陈述描述了你应该能做到的事情，例如“我能描述声音如何传播”或“我能画出串联电路图”。
Building a strong foundation in Year 7 is crucial for GCSE Physics. The concepts of energy transfers, force diagrams, and electric circuits reappear in much greater depth later. Ask questions, revise regularly, and try to link lessons to the real world.
在七年级打下坚实基础对GCSE物理至关重要。能量转移、力图和电路等概念在以后会以更深的层次再次出现。要勤于提问，定期复习，并尝试将课堂知识与现实世界联系起来。
12. Learning Resources and Study Tips | 学习资源与学习建议
To succeed in Year 7 physics, use a variety of resources. The AQA KS3 Science textbooks, CGP revision guides, and online platforms like BBC Bitesize are excellent. Make summary notes, flashcards for key equations, and mind maps connecting big ideas.
要在七年级物理中取得成功，请使用多种资源。AQA KS3科学教科书、CGP复习指南以及诸如BBC Bitesize之类的在线平台都非常好。制作摘要笔记、关键公式的闪卡，以及连接大概念的思维导图。
Watching documentaries about space or engineering can spark curiosity. Simple home experiments – building a basic circuit with a kit, dropping objects to compare gravity, or making a periscope – can reinforce classroom learning.
观看关于太空或工程的纪录片可以激发好奇心。简单的家庭实验——用套件搭建基本电路、丢下物体比较重力，或制作潜望镜——可以巩固课堂学习。
Collaborate with classmates: explaining a concept to someone else is one of the best ways to learn. If you get stuck, write your question down and ask your teacher. Physics is about understanding principles, not just memorising facts.
与同学合作：向他人解释一个概念是最好的学习方法之一。如果遇到困难，写下你的问题并询问老师。物理是关于理解原理的，而不仅仅是记忆事实。
Finally, keep a physics glossary where you record new words like ‘refraction’, ‘frequency’, and ‘newton’. Understanding the language of physics makes it much easier to answer exam questions accurately and with confidence.
最后，准备一个物理词汇表，记录像“折射”、“频率”和“牛顿”这样的新词汇。理解物理语言会让你更准确、更自信地回答考试问题。
