📚 Year 7 WJEC Physics: Complete Course Syllabus Overview | Year 7 WJEC 物理：课程大纲全面解析
In Year 7, WJEC Physics introduces students to the fundamental principles that govern the physical world, building scientific curiosity and practical skills. This comprehensive guide walks through the entire syllabus, covering key topics from energy and forces to waves, electricity, and space, while emphasising how these concepts are assessed and applied.
在 Year 7 阶段，WJEC 物理课程带领学生探索支配物理世界的基本原理，培养科学好奇心和实践技能。这篇全面解析将逐模块梳理课程大纲，涵盖能量、力、波、电与太空等核心主题，并强调这些概念的评估方式与实际应用。
1. Introduction to Energy | 能量入门
Energy is the ability to do work, and it is the central theme that runs through all of physics. In Year 7, students learn to identify different energy stores such as kinetic, thermal, chemical, gravitational potential, elastic potential, and nuclear energy.
能量是做功的能力，也是贯穿物理学始终的核心主题。Year 7 学生要学会识别不同的能量储存方式，如动能、热能、化学能、重力势能、弹性势能和核能。
Energy can be transferred from one store to another through pathways like heating, electrical work, mechanical work, and radiation. The key principle is that energy is always conserved; it cannot be created or destroyed, only transferred or converted.
能量可以通过加热、电功、机械功和辐射等途径在不同储存之间转移。关键原理是能量始终守恒：它不能被创造或消灭，只能被转移或转化。
- Kinetic energy – energy of moving objects.
- 动能——运动物体的能量。
- Thermal energy – energy related to temperature.
- 热能——与温度相关的能量。
- Gravitational potential energy – energy stored due to height.
- 重力势能——因高度而储存的能量。
Practical activities often involve measuring temperature changes during energy transfers, such as mixing hot and cold water, and using simple Sankey diagrams to represent energy flows visually.
实践活动通常包括在能量转移过程中测量温度变化，如混合热水和冷水，并使用简单的桑基图直观表示能量流动。
2. Forces and Motion | 力与运动
Forces are pushes or pulls that can change the speed, direction, or shape of an object. Students begin by studying contact forces (friction, air resistance, tension) and non-contact forces (gravity, magnetic and electrostatic forces).
力是一种推或拉，能改变物体的速度、方向或形状。学生们首先学习接触力（摩擦力、空气阻力、张力）和非接触力（重力、磁力和静电力）。
A resultant force causes acceleration or deceleration. If forces on an object are balanced, it remains at rest or moves at a constant speed. Unbalanced forces lead to a change in motion, described qualitatively through Newton's First Law.
合力会导致加速或减速。如果物体受平衡力作用，它将保持静止或匀速直线运动；非平衡力会导致运动状态的改变，这可以通过牛顿第一定律进行定性描述。
Students calculate speed using the formula:
average speed = total distance ÷ total time
学生用公式计算速度：
平均速度 = 总距离 ÷ 总时间
Graphs of distance against time are interpreted, and the gradient represents speed. Practical work includes timing trolleys down ramps, measuring friction on different surfaces, and investigating the elastic limit of springs.
学生需要解释距离-时间图像，其斜率代表速度。实践工作包括测量小车沿斜面下滑的时间、在不同表面上测量摩擦力，以及研究弹簧的弹性限度。
3. Waves: Sound and Light | 波：声与光
Waves transfer energy without transferring matter. In Year 7, the focus is on two types of waves: sound, which is a longitudinal mechanical wave, and light, an electromagnetic transverse wave that does not need a medium.
波传递能量而不传递物质。Year 7 的重点是两种波：声波是一种需要介质传播的纵波，而光波是一种不需要介质的电磁横波。
Sound travels through solids, liquids, and gases by causing particles to vibrate. Its speed depends on the medium; it travels fastest in solids. Key concepts include pitch (determined by frequency) and loudness (determined by amplitude).
声音通过引起粒子振动在固体、液体和气体中传播。其速度取决于介质，在固体中传播最快。核心概念包括音调（由频率决定）和响度（由振幅决定）。
For light, students explore how light travels in straight lines, leading to the formation of shadows. They investigate reflection, using ray boxes to demonstrate the law of reflection (angle of incidence equals angle of reflection). Refraction is introduced qualitatively, showing how light bends when passing between media of different densities.
对于光，学生探索光沿直线传播的性质，这导致影子的形成。他们研究反射，用光线盒演示反射定律（入射角等于反射角）。折射也进行定性介绍，展示光在穿过不同密度介质时如何弯曲。
The visible spectrum is broken down into seven colours, and students may combine primary colours of light (red, green, blue) to produce secondary colours. The electromagnetic spectrum is mentioned as a family of transverse waves with various uses and dangers.
可见光谱被分解为七种颜色，学生可通过叠加光的三原色（红、绿、蓝）来产生二次色。电磁波谱被提及为一组具有各种用途和危害的横波家族。
4. Electricity and Circuits | 电与电路
Electricity is the flow of charge, typically carried by electrons in a conductor. Year 7 introduces basic circuit components: cells, batteries, switches, bulbs, buzzers, motors, and resistors. The difference between series and parallel circuits is a key learning objective.
电是电荷的流动，通常由导体中的电子携带。Year 7 介绍基本电路元件：电池、开关、灯泡、蜂鸣器、马达和电阻器。串联和并联电路的区别是一个关键学习目标。
In a series circuit, there is only one path for current to flow; if one component breaks, the whole circuit stops. In parallel circuits, each component is on its own loop, so if one fails, others continue to work. This explains why domestic wiring uses parallel connections.
串联电路只有一条电流通路，如果一个元件损坏，整个电路停止工作。并联电路中每个元件处于独立回路，因此一个损坏时其他仍能工作，这也解释了家庭布线采用并联方式的原因。
Students measure current using ammeters (connected in series) and measure voltage (potential difference) using voltmeters (connected in parallel). The unit of current is the ampere (A) and of voltage the volt (V). Resistance is introduced conceptually, and the qualitative relationship is given as:
V = I × R
学生使用电流表（串联）测量电流，使用电压表（并联）测量电压（电位差）。电流的单位是安培（A），电压的单位是伏特（V）。电阻被引入概念，定性关系为：
V = I × R
Conductors and insulators are distinguished by how easily charges move through them. Static electricity may be introduced briefly, showing how insulating materials can become charged by friction, transferring electrons.
导体和绝缘体通过电荷在其中移动的难易程度来区分。可能会简要介绍静电，展示绝缘材料如何通过摩擦转移电子而带电。
5. Matter: Solids, Liquids and Gases | 物质的状态：固体、液体和气体
Everything is made of particles. The particle model helps explain the properties of solids, liquids, and gases. In solids, particles are tightly packed in a regular pattern and only vibrate; in liquids, particles are close but can move past each other; in gases, particles are far apart and move randomly at high speeds.
万物由粒子组成。粒子模型有助于解释固体、液体和气体的性质。固体中粒子紧密有序排列，只能振动；液体中粒子接近但可以相对滑动；气体中粒子相距很远，高速随机运动。
Changes of state—melting, freezing, boiling, condensation, sublimation—are physical changes that involve energy transfer. When a substance changes state, its temperature remains constant until the change is complete, because energy is used to break or form bonds rather than raise temperature.
状态变化——熔化、凝固、沸腾、冷凝、升华——是涉及能量转移的物理变化。物质发生状态变化时，温度在变化完成前保持不变，因为能量被用于打破或形成键而不是升高温度。
Diffusion experiments, such as potassium manganate(VII) spreading in water or the smell of perfume across a room, provide evidence for the particle model. Brownian motion (observed with smoke particles) is another classic example showing random particle movement.
扩散实验，如高锰酸钾在水中扩散或香水气味弥漫房间，为粒子模型提供了证据。布朗运动（通过烟尘粒子观察）是表明粒子随机运动的另一个经典例子。
Pressure in gases is explained by particles colliding with container walls. Increasing temperature raises the kinetic energy of particles, increasing collisions and therefore pressure if volume is constant.
气体的压强调释为粒子与容器壁碰撞。升高温度会增加粒子动能，如果体积不变，碰撞增多则气压上升。
6. The Solar System and Beyond | 太阳系及其之外
In this topic, students explore Earth's place in the universe. The Solar System consists of the Sun, eight planets, their moons, dwarf planets, asteroids, and comets. Students learn the order of planets from the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
在这一课题中，学生探索地球在宇宙中的位置。太阳系包含太阳、八大行星、它们的卫星、矮行星、小行星和彗星。学生要学习行星离太阳的顺序：水星、金星、地球、火星、木星、土星、天王星、海王星。
The difference between a planet and a star is emphasised: stars generate their own light through nuclear fusion, whereas planets reflect starlight. Gravity is the force that holds the Solar System together. Moons orbit planets, and the Earth's Moon causes tides.
重点区分行星与恒星：恒星通过核聚变产生自己的光，而行星反射星光。重力是维持太阳系在一起的力。卫星围绕行星运行，地球的月球引起潮汐。
Seasons on Earth arise from the tilt of its axis (about 23.5°) as it orbits the Sun. Day and night are caused by Earth's rotation on its axis every 24 hours. A year is the time Earth takes to complete one orbit around the Sun.
地球上的四季源于地轴倾角（约23.5°）以及地球绕日公转。昼夜由地球每24小时绕地轴自转一周引起。一年是地球绕太阳公转一周所需的时间。
A broader view includes the Milky Way as the galaxy that contains our Solar System, and the fact that the Universe contains billions of galaxies. The concept of light-years as a distance scale may be touched upon when discussing the vastness of space.
更广阔的视野包括银河系作为包含我们太阳系的星系，以及宇宙包含数十亿个星系的事实。讨论宇宙的浩瀚时，可能提及光年作为距离尺度的概念。
7. Scientific Enquiry Skills | 科学探究技能
WJEC embeds scientific enquiry throughout the Year 7 physics course. Students learn to formulate hypotheses, identify independent, dependent, and control variables, and design fair tests. These skills are essential for all practical investigations.
WJEC 将科学探究贯穿 Year 7 物理课程。学生学习如何提出假设，识别自变量、因变量和控制变量，并设计公平测试。这些技能对所有实践探究都至关重要。
Data collection involves using appropriate equipment (stopwatches, thermometers, ammeters) and recording results systematically in tables. Students then process data by calculating averages, plotting graphs (line graphs or bar charts), and identifying patterns or anomalies.
数据收集包括使用适当的设备（秒表、温度计、电流表）并系统地将结果记录在表格中。学生接着通过计算平均值、绘图（折线图或条形图）并识别规律或异常来处理数据。
Making conclusions requires relating findings back to the hypothesis and explaining results using scientific knowledge. Evaluating the method involves commenting on limitations, sources of error (random or systematic), and suggesting realistic improvements such as repeating measurements or using more precise instruments.
得出结论需要将发现与假设联系起来，并运用科学知识解释结果。评估方法包括评论局限性、误差来源（随机或系统误差），并提出切实的改进建议，如重复测量或使用更精密的仪器。
Key terms such as accuracy, precision, repeatability, and reproducibility are introduced in a simple, age-appropriate way. A typical investigation might be: 'How does the length of a wire affect the brightness of a bulb?' or 'How does the mass on a spring affect its extension?'
准确性、精确度、可重复性和再现性等关键术语以适合年龄的简单方式引入。典型实验可能是：“导线长度如何影响灯泡亮度？”或“弹簧上的质量如何影响其伸长量？”
8. Practical Assessments and Key Skills | 实践评估与关键技能
Practical work is not just a teaching tool but also an assessed component. Students are expected to handle apparatus safely, follow instructions, and make careful observations. They must also identify hazards and take simple precautions to minimise risk.
实践操作不仅是教学工具，也是评估组成部分。学生应能安全地操作仪器，遵循指令并进行细致观察。他们还必须识别危险并采取简单的预防措施以降低风险。
Measurement skills include reading scales to the correct degree of precision and recording units. Time, length, mass, temperature, current, and voltage are the most common physical quantities measured. Students should be able to use prefixes like milli- (10⁻³), centi- (10⁻²), and kilo- (10³).
测量技能包括正确读取刻度并记录单位。时间、长度、质量、温度、电流和电压是最常测量的物理量。学生应能使用毫（10⁻³）、厘（10⁻²）和千（10³）等词头。
Graphical skills involve choosing suitable scales, labelling axes with units, plotting points accurately, and drawing lines of best fit. Interpretation includes determining gradients and intercepts where relevant, and using graphs to make predictions (interpolation and extrapolation).
绘图技能包括选择合适的比例、标注轴与单位、精确描点并画出最佳拟合线。解释技能包括在适当情况下确定斜率和截距，以及利用图线进行预测（内插法和外推法）。
Common equipment used in Year 7 includes spring balances, measuring cylinders, electrical cells, ray boxes, signal generators, and data loggers. Familiarity with these tools builds confidence for further study.
Year 7 常用器材包括弹簧秤、量筒、电池、光线盒、信号发生器和数据采集器。熟悉这些工具能为后续学习建立信心。
9. How to Succeed in Year 7 Physics | 如何学好 Year 7 物理
Success in Year 7 WJEC Physics depends on consistent engagement with both theory and practical work. Here are five strategies that make a real difference. First, always review lesson notes within 24 hours and create colourful mind maps to link concepts like energy stores and forces.
学好 Year 7 WJEC 物理需要持续投入理论与实验。以下是五个真正有效的策略。第一，每次课后24小时内复习笔记，并制作彩色思维导图来连接能量储存和力等概念。
Second, master key vocabulary. Learn to spell and define terms such as 'resultant force', 'amplitude', 'potential difference', and 'gravitational field', because exam questions often test precise definitions. Third, complete all assigned practicals with focus—record observations in real time rather than relying on memory later.
第二，掌握关键词汇。学会拼写并定义诸如“合力”、“振幅”、“电位差”和“引力场”等术语，因为考试常会测试精确定义。第三，专注完成所有指定的实验——实时记录观察，不要靠事后回忆。
Fourth, practise numerical work. Simple rearrangements of formulas for speed and Ohm's law require confidence with division and multiplication. Use the triangle method if needed. Fifth, connect physics to daily life. When you see a rainbow, think of dispersion; when you kick a ball, think about force pairs and momentum (later on).
第四，练习数值计算。速度和欧姆定律公式的简单变形需要熟练掌握除法与乘法，必要时可使用三角法。第五，将物理与日常生活联系起来。看到彩虹时想想色散；踢球时想想力对和动量（稍后阶段）。
Using past paper questions, even in Year 7, helps familiarise you with the command words: 'state', 'describe', 'explain', 'calculate'. 'Explain' requires a reason, often linking cause and effect scientifically.
即使 Year 7 也可以使用历年试题，这有助于熟悉指令词：“陈述”、“描述”、“解释”、“计算”。“解释”需要给出理由，通常用科学原理关联因果。
