2. The Engineering Design Process | 工程设计流程

At the heart of every project is a structured design process: Define the problem, research existing products, brainstorm possible solutions, select the best idea, model and prototype, test and evaluate, and finally make improvements. This cycle is repeated until the design meets all the requirements.

每个课题的核心都是一套结构化的设计流程：定义问题、调研现有产品、头脑风暴构思方案、选出最佳创意、建模并制作原型、测试与评价，最后进行修改。这一循环会不断重复，直到设计满足所有要求为止。

Understanding each stage helps you manage your time and resources effectively. For example, during the research phase, you might analyse how a mobile phone stand supports a device; in the prototyping stage, you could build a cardboard mock-up before cutting expensive materials. This systematic approach is exactly what Edexcel examiners look for in your project work.

理解每一个阶段有助于有效管理时间和资源。例如，在研究阶段，你可能会分析手机支架如何支撑设备；在原型阶段，你可以在切割昂贵材料之前先用硬纸板做出模型。这种系统化的方法正是 Edexcel 考官在课题作业中所看重的。

3. Materials and Their Properties | 材料及其特性

Engineers choose materials based on properties such as strength, hardness, flexibility, conductivity, and density. In KS3, you’ll work with wood, metals, plastics, and composite materials. For instance, softwood like pine is easy to cut and shape, while acrylic plastic is shatter-resistant and often used for lightweight enclosures.

工程师根据强度、硬度、柔韧性、导电性和密度等特性来选择材料。在 KS3 课程中，你会用到木材、金属、塑料和复合材料。例如，像松木这样的软木易于切割和塑形，而亚克力塑料具有抗摔碎特性，常用于制作轻便的外壳。

You will also learn to distinguish between ferrous and non-ferrous metals. Ferrous metals contain iron and are magnetic – think of steel – while non-ferrous metals like aluminium and copper are lighter and resist corrosion. Selecting the right material early can save both cost and weight in a design.

你还将学习区分黑色金属与有色金属。黑色金属含铁且可被磁铁吸引，例如钢；而铝、铜等有色金属更轻且耐腐蚀。在设计初期选出合适的材料，能节省成本和减轻重量。

4. Basic Mechanics and Forces | 基础力学与力

Every structure must withstand forces such as tension, compression, torsion, and shear. A bridge, for example, experiences compression in its top beams and tension in its lower cables. Understanding these forces allows you to design shapes that are strong yet use minimal material, like triangles in truss bridges.

任何结构都必须承受拉力、压力、扭力和剪切力等。例如，一座桥梁的顶部梁承受压力，而下部钢缆则承受拉力。理解这些力，你就能设计出既坚固又省料的形状，比如桁架桥中的三角形结构。

A simple but powerful equation you will encounter is moment = force × perpendicular distance (M = Fd). In a lever, a small effort can lift a large load if the effort is applied far from the pivot. This principle explains why spanners, scissors, and even wheelbarrows make work easier.

你会遇到一个简单而强大的公式：力矩 = 力 × 垂直距离（M = Fd）。在杠杆中，若施力点离支点足够远，则较小的力就能抬起重物。这一原理解释了为什么扳手、剪刀甚至手推车都能让工作更省力。

5. Introduction to Electronics | 电子学入门

Electronics in KS3 Engineering introduces you to basic components such as batteries, resistors, LEDs, switches, and sensors. You’ll build circuits on breadboards and learn to read simple circuit diagrams. Understanding polarity – the positive and negative sides of a component – is crucial to avoid short circuits.

KS3 工程的电子学部分会带你认识电池、电阻器、发光二极管（LED）、开关和传感器等基础元件。你将在面包板上搭建电路，并学会阅读简单的电路图。理解极性（元件的正极和负极）对避免短路至关重要。

Key relationships are introduced through Ohm’s law: V = I × R, where V is voltage in volts, I is current in amps, and R is resistance in ohms (Ω). For example, if a 9 V battery connects to a 300 Ω resistor, the current flowing would be I = 9 / 300 = 0.03 A, or 30 mA. This lets you predict component behaviour before building.

通过欧姆定律可以理解关键关系：V = I × R，其中 V 是以伏特为单位的电压，I 是以安培为单位的电流，R 是以欧姆（Ω）为单位的电阻。例如，9 V 电池连接到 300 Ω 电阻时，流过的电流为 I = 9 / 300 = 0.03 A，即 30 mA。这让你可以在搭建之前预测元件的行为。

6. Manufacturing Techniques | 制造技术

You will get hands-on with marking-out tools, saws, files, drills, and strip heaters for bending plastics. Accuracy is critical: measuring and marking twice before cutting prevents wasted material. The engineering mantra ‘measure twice, cut once’ will quickly become second nature in the workshop.

你将亲手使用划线工具、锯、锉刀、电钻以及用于弯曲塑料的条形加热器。精确度至关重要：切割前进行两次测量和标记，能避免材料浪费。工程师座右铭“两次测量，一次切割”很快就会在车间成为你的第二天性。

Joining methods vary with material. Woods are often glued with PVA or joined with screws and nails, while metals may be riveted, bolted, or soldered. Plastics can be joined through plastic welding or solvent cement for acrylic. Knowing which method to use for a given situation is a core practical skill.

连接方法因材料而异。木材通常用 PVA 胶水粘接，或用螺丝、钉子固定；金属则可能需要铆接、螺栓连接或锡焊。塑料可以通过塑料焊接或亚克力溶剂胶进行连接。能够根据实际情况选用正确的连接方法，是一项核心实操技能。

7. Design Communication: Sketching and Drawing | 设计沟通：草图与绘图

Engineers must communicate ideas clearly. In KS3, you’ll practise freehand sketching, isometric drawing, and orthographic projection. An isometric drawing shows a 3D object on 2D paper using 30-degree angles, giving a clear visual of height, width, and depth in one view.

工程师必须清晰地传达想法。在 KS3 阶段，你将练习徒手草图、等轴测图以及正投影图。等轴测图利用 30 度角在二维纸上展示三维物体，只需一张图就能直观体现高、宽、深。

Annotation is equally important: adding notes about dimensions, materials, and surface finishes directly onto your drawing. This helps others – and you, when you revisit the design – to understand the thinking behind each feature. Digital tools like 2D CAD may also be introduced at this stage.

标注同样重要：在图纸上直接添加尺寸、材料和表面处理等注释。这有助于他人（以及日后翻阅设计的你自己）理解每个特征背后的思考。此阶段还可能引入二维 CAD 等数字工具。

8. Health and Safety in Engineering | 工程中的健康与安全

A safe workshop is the absolute priority. You will learn how to identify hazards, use protective equipment such as goggles, aprons, and dust masks, and follow strict rules when operating machinery. Risk assessments are a routine part of every practical task, teaching you to spot dangers before they cause harm.

安全的车间环境是绝对优先事项。你将学习识别危险源，使用护目镜、围裙和防尘口罩等防护装备，并在操作机器时遵守严格规定。风险评估是每项实操作业的常规环节，教你预先发现隐患，防患于未然。

Common safety signs and colour codes – red for prohibition, yellow for warning, blue for mandatory action, and green for safe conditions – are used throughout the workshop. Understanding these symbols ensures you can work confidently in any practical environment.

车间内遍布常见的安全标识和彩色代码——红色代表禁止，黄色代表警告，蓝色代表强制行为，绿色代表安全条件。理解这些符号能确保你在任何实践环境中自信地工作。

9. Sustainability and Environmental Impact | 可持续性与环境影响

Modern engineering is deeply concerned with sustainability. You’ll explore the ‘6 Rs’ of sustainable design: Reduce, Reuse, Recycle, Repair, Refuse, and Rethink. For example, designing a product that uses fewer materials (reduce) or can be easily disassembled for repair both lower environmental footprint.

现代工程高度关注可持续性。你将探索可持续设计的“6R”原则：减少使用、重复利用、回收再生、维修、拒绝使用和重新思考。例如，设计一款使用更少材料（减少）或易于拆解维修的产品，都能降低环境足迹。

Lifecycle analysis (LCA) is introduced at a basic level, examining the energy and waste involved from raw material extraction, manufacturing, and distribution to product use and disposal. Choosing renewable materials and local suppliers can dramatically cut a product’s carbon footprint.

课程会基础性地介绍生命周期分析（LCA），考察从原材料开采、制造、分销到产品使用和废弃过程中所涉及的能耗与废弃物。选择可再生材料和本地供应商，可以显著降低产品的碳足迹。

10. Simple Machines and Mechanical Systems | 简单机械与机械系统

Simple machines – levers, pulleys, wheels and axles, inclined planes, screws, and wedges – form the building blocks of complex mechanisms. You’ll examine how a gear train can increase torque or speed, depending on gear ratios. In a bicycle, for instance, shifting to a larger rear gear makes pedalling easier to climb hills.

简单机械——杠杆、滑轮、轮轴、斜面、螺钉和楔子——构成了复杂机构的基本元件。你将研究齿轮系如何根据齿轮比来增加扭矩或速度。例如在自行车上，换到较大的后齿轮能让上坡踏行更省力。

Edexcel often uses real-life case studies: analysing a can opener reveals linkages and levers, while a conveyor belt model shows belt and pulley systems. Creating physical models of these mechanisms helps you grasp mechanical advantage and efficiency calculations.

Edexcel 课程常采用真实案例研究：分析开罐器能揭示连杆和杠杆原理，而传送带模型则展示了带轮系统。制作这些机构的实体模型能帮助你理解机械增益和效率的计算。

---

11. Programming and Control Systems | 编程与控制系统

An introduction to control is often included through block-based coding platforms like microcontrollers (e.g., micro:bit or Crumble). You’ll write simple programs to make LEDs flash, respond to button presses, or read a light sensor. This merges physical computing with engineering design.

控制系统入门通常通过基于块的编程平台（如 micro:bit 或 Crumble）来进行。你会编写简单程序，让 LED 闪烁、响应按钮按压或读取光线传感器。这实现了物理计算与工程设计的融合。

Flowcharts are used to plan programmes: diamonds represent decisions, rectangles show processes, and parallelograms indicate inputs or outputs. Translating a real-world problem – like ‘if it gets dark, turn on the night light’ – into a flowchart reinforces logical thinking vital for a career in engineering.

流程图用来规划程序：菱形代表判断，矩形表示过程，平行四边形指示输入或输出。将现实问题（如“如果天黑，就打开夜灯”）转化为流程图，能增强逻辑思维，这对工程职业至关重要。

12. Summer Bridging Activities to Try at Home | 暑期在家可做的衔接活动

Prepare for KS3 Engineering by building a simple structure from spaghetti and marshmallows – test its strength and record where it fails. This mimics the iterative design process and introduces forces in action. Experiment with different shapes and note which ones bear the most load.

用意大利面和棉花糖搭建简单结构，测试其强度并记录断裂位置，为 KS3 工程做好准备。这模拟了迭代设计过程，并呈现力的作用。尝试不同形状，记录哪种形状承重最大。

Take apart an old household electronic device (unplugged, with adult supervision) to identify components and materials. Draw a labelled sketch of what you find, and research how each part functions. Keeping a summer engineering diary with sketches, ideas, and observations will give you a huge head start.

在成人监护下拆解一件废旧家用电子设备（务必拔下插头），识别其中的元件和材料。为你发现的东西绘制标注草图，并研究每个零件的功能。用一本暑期工程日记记录草图、构思和观察，这将带给你巨大的先发优势。

Finally, watch online engineering documentaries or virtual factory tours to see mass production lines and robotic assembly. Make notes on how machines are controlled and how quality is checked. The more you connect book theory with the real world, the more confident and inspired you will feel in September.

最后，观看线上工程纪录片或虚拟工厂参观，了解批量生产线和机器人装配。记录机器如何受控以及质量如何检验。把书本理论与现实世界连接得越多，九月份开学时你就会越自信、越有灵感。
