📚 Year 7 WJEC Physics: Winter Intensive Revision Plan | 七年级 WJEC 物理：寒假强化复习计划
The winter holiday offers a brilliant opportunity to consolidate everything you have learned in Year 7 Physics so far. A well-structured revision plan not only helps you catch up on tricky topics but also builds confidence for the new term ahead. This guide will give you a step-by-step strategy to make your winter revision effective, stress-free and even enjoyable.
寒假为巩固你在七年级物理中已学的一切提供了一个绝佳的机会。一个安排合理的复习计划不仅能帮助你补上较难的主题，还能为迎接新学期树立信心。本指南将为你提供一步步的策略，让寒假复习变得高效、无压力甚至充满乐趣。
1. Why Winter Break is the Perfect Revision Window | 为什么寒假是复习的黄金窗口
During term time, new topics come thick and fast, leaving little room for deep reflection. The winter break gives you uninterrupted time to revisit ideas, plug gaps in understanding, and link concepts together without the pressure of daily homework. Short, focused bursts of revision spread across the holiday are far more effective than last-minute cramming.
在上课期间，新课题接连不断，几乎没有留下深入思考的空间。寒假为你提供了不受干扰的时间来重温概念、填补理解漏洞，并在没有每日作业压力的情况下将概念串联起来。把短时间、高专注的复习分散在整个假期里，远比临时抱佛脚有效得多。
Moreover, research shows that revisiting material after a break strengthens long-term memory – a process called spaced repetition. By designing a plan now, you can use the holiday to lock in knowledge that will serve you well for end-of-year tests and beyond.
此外，研究表明，在休息一段时间后重温材料能加强长时记忆——这个过程被称为间隔重复。现在制定一个计划，你就能利用假期把知识牢牢锁定，这将对年终测试甚至以后的考试大有裨益。
2. Taking Stock: Assess Your Current Understanding | 盘点：评估你的现有理解水平
Before diving into revision, make a quick list of every physics topic you have covered since September. Look through your exercise book, textbook and any online resources your school uses. Rate each topic using a simple traffic light system: green for ‘I get this’, amber for ‘I’m a bit shaky’, and red for ‘I really need help with this’. This honest self-assessment stops you wasting time on things you already know well.
在投入复习之前，先把自九月以来学过的每一个物理主题列出来。翻阅你的练习本、教科书以及学校使用的任何在线资源。用一个简单的交通灯法给每个主题打分：绿色代表“我已掌握”，琥珀色代表“我有点不牢”，红色代表“我真的需要帮助”。这种诚实的自我评价可以避免你在已经熟悉的内容上浪费时间。
Your list might include topics such as forces, speed, gravity, energy stores, circuits, current, voltage, the particle model and density. Highlight any red or amber topics – these will become the focus of your first revision sessions.
你的清单可能包括力、速度、重力、能量储存、电路、电流、电压、粒子模型和密度等主题。把任何红色或琥珀色的主题标出来——这些将成为你最初复习的重点。
3. Set SMART Revision Goals for Physics | 为物理复习设定 SMART 目标
Vague goals like ‘I will revise physics’ rarely work. Instead, use SMART goals: Specific, Measurable, Achievable, Relevant and Time-bound. For example, a SMART goal could be: ‘By the end of this week, I will be able to calculate speed using distance and time and explain three examples of energy transfers.’ This makes it easy to check if you have succeeded.
像“我要复习物理”这样模糊的目标几乎不起作用。相反，要使用 SMART 目标：具体的、可衡量的、可实现的、相关的和有时限的。例如，一个SMART目标是：“到本周末，我能够使用距离和时间计算速度，并解释三个能量转移的例子。”这样你就能很容易地检查是否成功实现了目标。
Write down two or three SMART goals for the holiday. Pin them near your study space so you can see them every day. Ticking off a goal gives a real sense of achievement and motivates you to tackle the next one.
为这个假期写下两到三个 SMART 目标。把它们贴在靠近学习空间的地方，让你每天都能看到。完成一个目标并打上勾会带来真正的成就感，并激励你去攻克下一个目标。
4. Key Topic 1: Forces and Motion | 核心主题1：力与运动
Forces are pushes or pulls that can change an object's speed, shape or direction. In Year 7, you need to understand contact forces (like friction and air resistance) and non-contact forces (like gravity and magnetism). Revise the difference between mass (measured in kilograms) and weight (the force of gravity on a mass, measured in newtons). Remember the equation:
力是能改变物体速度、形状或方向的推或拉。在七年级，你需要理解接触力（如摩擦力和空气阻力）和非接触力（如重力和磁力）。复习质量（以千克为单位）与重力（地球对物体质量的引力，以牛顿为单位）之间的区别。记住下面这个方程：
weight (N) = mass (kg) × gravitational field strength (N/kg)
重量 (N) = 质量 (kg) × 重力场强度 (N/kg)
On Earth, gravitational field strength is roughly 10 N/kg, so a 50 kg student has a weight of about 500 N. Practise using this triangle to rearrange the equation.
在地球上，重力场强度大约为 10 N/kg，因此一个 50 kg 的学生的重量约为 500 N。练习使用这个三角形来重新排列方程。
ce ÷ time. Always use consistent units: metres for distance and seconds for time give speed in m/s. You should also be able to draw and interpret simple distance– that a steeper slope means higher speed and a flat section means the object is stationary.
在学习运动时，速度告诉你物体移动的快慢。你应当遇到过公式 速度 = 距离 ÷ 时间。始终使用统一的单位：距离用米，时间用秒，则速度单位为 m/s。你还应该能绘制并解读简单的距离-时间图像，认识到：斜率越大表示速度越大，水平段表示物体静止。
5. Key Topic 2: Energy Stores and Transfers | 核心主题2：能量的储存与转移
Energy is a central idea in physics. It cannot be created or destroyed – only transferred from one store to another. The main energy stores you need to know are: kinetic, gravitational potential, elastic potential, thermal (internal), chemical and nuclear. Use the phrase ‘King George Eats Cold Noodles’ (Kinetic, Gravitational potential, Elastic potential, Chemical, Nuclear) as a memory aid, though you should also remember thermal and other stores.
能量是物理学的核心概念。它不能被创造或消灭，只能从一种储存转移到另一种储存。你需要了解的主要能量储存有：动能、重力势能、弹性势能、热能（内能）、化学能和核能。可以用口诀帮助记忆，同时你也得记住热能和其他储存。
Energy can be transferred in four ways: by forces doing work (mechanically), by electric currents (electrically), by heating (thermally) and by light or sound (radiation). For example, when you lift a book, chemical energy in your muscles is transferred mechanically into gravitational potential energy. When you turn on a lamp, energy stored in the battery or mains supply is transferred electrically into light and thermal energy.
能量可以通过四种方式转移：通过力做功（机械方式）、通过电流（电方式）、通过加热（热方式）以及通过光或声音（辐射方式）。例如，当你举起一本书时，你肌肉中的化学能通过机械方式转移为重力势能。当你打开一盏灯时，储存在电池或电源中的能量通过电方式转移为光能和热能。
Conservation of energy means the total energy before a transfer equals the total after. A common misconception is that energy is ‘used up’. Instead, it is dissipated – spread out into less useful stores, often heating the surroundings. Use energy transfer diagrams (Sankey diagrams) to show what happens to every joule.
能量守恒意味着转移前的总能量等于转移后的总能量。一个常见的误解是能量被“用光”了。实际上，能量是被耗散了——扩散到不太有用的储存中，通常是使周围环境变热。使用能量转移图（桑基图）来展示每一焦耳的去向。
6. Key Topic 3: Electricity and Circuits | 核心主题3：电与电路
Electricity in Year 7 covers building simple circuits and measuring current and voltage. Current is the flow of electric charge, measured in amperes (amps, A) using an ammeter connected in series. Voltage (potential difference) is the push that drives the current, measured in volts (V) using a voltmeter connected in parallel across a component.
七年级的电学内容涵盖搭建简单电路以及测量电流与电压。电流是电荷的流动，用电流表串联测量，单位为安培（amp，A）。电压（电势差）是驱动电流的“推力”，用电压表并联在某个元件两端测量，单位为伏特（V）。
You need to understand the difference between series and parallel circuits. In a series circuit, there is a single loop; current is the same everywhere, but voltage is shared between components. In a parallel circuit, there are multiple branches; voltage is the same across each branch, but current splits. Try drawing circuit diagrams using the correct symbols for cells, batteries, bulbs, switches, buzzers and motors.
你需要理解串联与并联电路的区别。在串联电路中，只有一条回路；各处电流相同，但电压在各元件间分配。在并联电路中，有多条支路；各支路两端电压相同，但电流会分流。尝试使用正确的符号画出电路图，包括电池、电池组、灯泡、开关、蜂鸣器和电动机。
Conductors and insulators are also important. Metals are good conductors because they have free electrons, while plastics, rubber and wood are insulators. Always remember safety: never use mains electricity for your home experiments – stick to low-voltage batteries.
导体和绝缘体也很重要。金属是良好的导体，因为它们拥有自由电子，而塑料、橡胶和木头则是绝缘体。务必牢记安全：绝对不能使用市电进行家庭实验——只允许使用低压电池。
7. Key Topic 4: The Particle Model of Matter | 核心主题4：物质的粒子模型
The particle model helps explain the properties of solids, liquids and gases. All substances are made of tiny particles – atoms, molecules or ions – that are constantly moving. In solids, particles vibrate in fixed positions and are arranged regularly. In liquids, particles are close but can slide past each other. In gases, particles are far apart and move rapidly in all directions.
粒子模型帮助解释固体、液体和气体的性质。所有物质都由微小的粒子——原子、分子或离子——组成，这些粒子在不停地运动。在固体中，粒子在固定位置振动，排列整齐。在液体中，粒子紧挨在一起但能相互滑动。在气体中，粒子相距很远，朝各个方向快速运动。
Use this model to explain why solids have a fixed shape and volume, liquids have a fixed volume but take the shape of their container, and gases fill any container completely. You should also link the model to density: a substance is denser when its particles are packed more tightly. The formula for density is:
用这个模型来解释为什么固体有固定的形状和体积，液体有固定的体积但形状随容器而变，而气体会完全充满任何容器。你还应该把模型与密度联系起来：当粒子排列得更紧密时，物质的密度就更大。密度的公式如下：
density (kg/m³) = mass (kg) ÷ volume (m³)
密度 (kg/m³) = 质量 (kg) ÷ 体积 (m³)
Changes of state – melting, freezing, boiling, condensing – can be explained by the energy gained or lost by particles. When a solid is heated, particles vibrate more until they break free, forming a liquid. This is a physical change, not a chemical one, which means no new substance is made.
物态变化——熔化、凝固、沸腾、凝结——可以用粒子获得或失去能量来解释。固体被加热时，粒子振动加剧，直到挣脱束缚形成液体。这是一种物理变化而非化学变化，这意味着没有新物质生成。
8. Other Topics to Keep an Eye On | 其他需要留意的主题
Depending on your school’s scheme of work, you may have touched upon waves, light and sound. Even if they have only been introduced briefly, it is worth spending a short time reviewing them. Sound is produced by vibrations and needs a medium to travel through, which is why you cannot hear anything in space. Light travels in straight lines, and you can draw ray diagrams to show reflection and refraction. Making a pinhole camera is a fun way to see how images are formed.
根据你学校的教学安排，你可能已经接触了波、光和声音。即使只是简略地介绍过，也值得花一小段时间复习它们。声音由振动产生，并且需要介质才能传播，这就是为什么在太空中你听不到任何声音。光沿直线传播，你可以画光路图来展示反射和折射。制作一个针孔照相机是一个有趣的方法，能让你看到图像是如何形成的。
Don't forget to check your WJEC specification or ask your teacher if you are unsure which topics have been covered. A mismatch between what you revise and what will be assessed can waste precious time.
如果你不确定哪些主题已经涵盖，别忘了查看你的 WJEC 课程大纲或询问你的老师。复习内容与考试范围不对口会浪费宝贵的时间。
9. A Sample Weekly Revision Timetable | 一周复习时间表示例
Consistency beats intensity. Aim for 30–40 minutes of physics revision per day with short breaks in between. Here is a sample timetable that mixes topics and activities to keep your brain engaged. Feel free to adapt it to your own traffic-light list.
持之以恒胜过一时的强度。目标是每天进行 30–40 分钟的物理复习，中间安排短暂休息。下面是一份示例时间表，它混合了不同主题和活动，以保持你的大脑投入。你可以根据自己的“交通灯”清单随意调整。
| Day | Focus / 重点 | Activity / 活动 |
|---|---|---|
| Mon 周一 | Forces & weight 力与重量 | Flashcards + weight calculations 闪卡 + 重量计算 |
| Tue 周二 | Energy stores 能量储存 | Mind map + label energy transfers 思维导图 + 标注能量转移 |
| Wed 周三 | Circuits & symbols 电路与符号 | Draw circuit diagrams + build a simple circuit 画电路图 + 搭建一个简单电路 |
| Thu 周四 | Particle model 粒子模型 | Explain states of matter to a family member 向家人解释物态 |
| Fri 周五 | Speed & graphs 速度与图像 | Practice questions + plot a distance–time graph 练习题 + 绘制距离-时间图 |
| Sat 周六 | Mixed quiz 混合测验 | Online quiz or past paper questions 在线测验或历年试卷题 |
| Sun 周日 | Rest & review 休息与回顾 | Scan notes; update traffic-light list 浏览笔记；更新交通灯清单 |
Adjust the timetable over the weeks. If you have three weeks of holiday, you might rotate through the four main topics twice, increasing the difficulty of the practice questions each time.
在几周内调整时间表。如果你有三周假期，你可以对四个核心主题轮换复习两遍，每次都增加练习题的难度。
10. Active Revision Techniques That Work | 有效的主动复习技巧
Simply reading your notes is a passive activity that often leads to ‘I think I know it’ syndrome. Instead, use active techniques that force you to retrieve information from memory. Here are some powerful methods:
仅仅阅读笔记是一种被动活动，常常导致“我以为我会了”的错觉。相反，要使用迫使你从记忆中提取信息的主动技巧。以下是一些有效的方法：
- Flashcards / 闪卡： Write a question on one side and the answer on the back. Test yourself and separate cards into ‘know’ and ‘not yet’ piles. / 一面写问题，另一面写答案。自我测试并将卡片分成“已掌握”和“尚未”两堆。
- Brain dumps / 脑内倾倒： After studying a topic, put your book away and write down everything you remember. Then check what you missed. / 学完一个主题后，把书合上，写下你能记起的所有内容。然后核对遗漏之处。
- Teach a teddy / 教给泰迪熊： Explain a concept aloud to a toy, pet or family member. If you get stuck, you know which part to revisit. / 大声向玩具、宠物或家人解释一个概念。如果你卡住了，就知道需要复习哪个部分。
- Dual coding / 双重编码： Combine words with simple diagrams. For example, draw a series circuit and label the current and voltage measurements. / 将文字与简图结合。例如，画一个串联电路并标出电流和电压的测量值。
Rotate between these techniques to keep revision fresh. Pairing active recall with spaced repetition (coming back to topics after a day, a week, a month) has been proven to make learning stick.
在这些技巧之间轮换可以让复习保持新鲜感。将主动回忆与间隔重复（在一天、一周、一个月后再次回到某个主题）相结合，已被证明能让学习更加牢固。
11. Hands-On Physics: Simple Home Experiments | 动手物理：简单的家庭实验
Physics is an experimental science, so doing a few safe, simple experiments at home can bring abstract ideas to life. Always ask an adult before starting and use common household items.
物理是一门实验科学，因此在家做一些安全、简单的实验可以让抽象的概念变得生动。开始前一定要征求成人同意，并使用常见的家庭用品。
with the formula v = d ÷ t, then change the height of the ramp and predict what will happen – this shows how gravitational potential energy converts to kinetic energy.
尝试测量一辆玩具车沿斜坡滚下的速度。用米尺测量距离，用秒表记录时间。用公式 v = d ÷ t 计算速度，然后改变斜坡的高度并预测会发生什么——这展示了重力势能如何转化为动能。
Build a simple circuit using a low-voltage battery, wires and a small bulb. Try adding more bulbs in series and observe what happens to their brightness. This demonstrates the concept of resistance and shared voltage. Alternatively, dissolve salt in water and see if the solution conducts electricity – a neat link to charged particles.
用低压电池、导线和一个小灯泡搭建一个简单电路。尝试串联更多灯泡，观察它们亮的程度如何变化。这展示了电阻和电压分配的概念。或者，将盐溶于水中，看看该溶液能否导电——这是与带电粒子之间精巧的联系。
For the particle model, place a drop of food colouring in a glass of hot water and another in cold water. The faster spread in hot water shows that particles move more rapidly when they have more thermal energy.
针对粒子模型，在热水和冷水中各滴入一滴食用色素。热水中扩散得更快，这表明当粒子拥有更多热能时，运动得更快。
12. Reflect, Adjust, and Stay Motivated | 反思、调整并保持动力
At the end of each week, take ten minutes to reflect. Ask yourself: Which topics now feel amber or green instead of red? Which study technique worked best? If something was boring or hard to stick to, change it. If you find you learn well by watching short videos, build one or two into your timetable – just make sure they are from a reliable source and no more than 5 minutes long.
每周结束时，花十分钟进行反思。问问自己：哪些主题从红色变成了琥珀色或绿色？哪种学习方法效果最好？如果某件事枯燥或者难以坚持，就调整它。如果你发现自己通过看短视频学得不错，就在时间表里安排一两个视频——但要确保它们来源可靠，时长不要超过5分钟。
Reward yourself after a good week. It doesn't have to be big – extra screen time, a favourite snack, or a trip to the park can keep your motivation high. Remember, revision is not about being perfect; it's about making progress one small step at a time.
在完成一周的良好复习后，给自己一点奖励。不需要很多——额外的屏幕时间、最爱的零食或去公园玩一圈都能让你保持高昂的积极性。记住，复习不是为了追求完美，而是为了日积月累的进步。
Finally, keep a positive mindset. Physics is fascinating because it explains how the world works, from why your bike doesn't fall over to how your phone lights up. The more you understand, the more you will enjoy it.
最后，保持积极的心态。物理之所以迷人，是因为它解释了世界如何运作——从为什么自行车不会倒下到你手机屏幕如何亮起。你理解得越多，就会越享受它。
