2. Overview of the Edexcel Engineering Course | 爱德思工程课程概览
The Edexcel GCSE in Engineering (1EN0) is structured around three main components: a written examination that tests your knowledge of engineering principles, a practical engineering project where you design and make a product, and an assessment of your understanding of materials, processes, and systems. The course covers mechanical, electronic, and structural engineering topics, as well as sustainability and the impact of engineering on society. You will learn to read and produce engineering drawings, work safely in a workshop, and evaluate the performance of a design.
爱德思GCSE工程课程（代码1EN0）围绕三大组成部分构建：考查工程原理知识的书面考试、一个让你设计与制作产品的实践工程项目，以及对你理解材料、工艺和系统的评估。课程涵盖机械、电子和结构工程主题，还涉及可持续性以及工程对社会的影响。你将学会阅读和绘制工程图纸，在车间安全地工作，并评估设计的性能。
3. Essential Mathematics for Engineers | 工程师必备数学基础
Engineering relies heavily on mathematics. Before Year 10 begins, review your skills in algebra, ratio and proportion, trigonometry, and units of measurement. You should be comfortable rearranging formulas such as V = IR or F = ma to solve for any variable. Practise using scientific notation and significant figures because precision is critical in engineering calculations. A strong grasp of gradient and area under a graph will also help you when you study motion, forces, and energy.
工程学高度依赖数学。在10年级开始之前，请复习代数、比例、三角学和测量单位方面的知识。你应该能熟练地重新排列公式，比如 V = IR 或 F = ma，以求解任何变量。练习使用科学记数法和有效数字，因为精度在工程计算中至关重要。如果你能深入理解图表的斜率和图形下方的面积，这对你将来学习运动、力和能量也很有帮助。
- Rearranging linear equations: y = mx + c → x = (y – c)/m
- Trigonometric ratios: sin θ = opposite/hypotenuse, cos θ = adjacent/hypotenuse, tan θ = opposite/adjacent
- Area of a circle: A = πr², circumference: C = 2πr
- 线性方程变形：y = mx + c → x = (y – c)/m
- 三角比：sin θ = 对边/斜边，cos θ = 邻边/斜边，tan θ = 对边/邻边
- 圆面积：A = πr²，周长：C = 2πr
F = ma (Force = mass × acceleration)
F = ma (力 = 质量 × 加速度)
4. Key Physics Concepts to Master | 需要掌握的关键物理概念
Engineering draws directly from physics, especially mechanics and electricity. Spend time understanding vectors and scalars—forces, velocity, and displacement are vectors with both magnitude and direction. Review Newton’s three laws of motion and be able to identify action–reaction pairs. In electricity, make sure you can distinguish between series and parallel circuits, and apply Ohm’s law (V = IR) and the power equation (P = IV). Energy transfers and efficiency are also fundamental themes.
工程学直接源于物理学，尤其是力学和电学。花些时间理解矢量和标量——力、速度和位移是既有大小又有方向的矢量。复习牛顿三大运动定律，并能够识别作用力与反作用力对。在电学方面，确保你能区分串联和并联电路，并应用欧姆定律（V = IR）和功率公式（P = IV）。能量转移与效率也是基本主题。
Efficiency = (Useful energy output ÷ Total energy input) × 100%
效率 = (有用的能量输出 ÷ 总能量输入) × 100%
5. Materials and Their Properties | 材料及其性能
Engineers select materials based on their mechanical, thermal, electrical, and optical properties. Key terms to learn include hardness, toughness, ductility, tensile strength, and conductivity. You will encounter metals like steel and aluminium, polymers such as acrylic and nylon, woods, composites, and smart materials. Understanding the difference between elastic and plastic deformation is essential when analysing how materials behave under load. Begin your summer by identifying materials in everyday objects and considering why they were chosen.
工程师根据材料的机械、热学、电学和光学性能来选用材料。需要学习的关键术语包括硬度、韧性、延展性、抗拉强度以及导电性。你将接触到钢铁和铝等金属、亚克力和尼龙等聚合物、木材、复合材料以及智能材料。理解弹性变形与塑性变形的区别对于分析材料在载荷下的行为至关重要。你可以从这个暑假开始，在日常生活中识别物品的材料，并思考选用原因。
| Property 性能 | Definition 定义 |
|---|---|
| Tensile strength 抗拉强度 | Ability to withstand pulling forces 承受拉力的能力 |
| Hardness 硬度 | Resistance to indentation or scratching 抵抗压入或划伤的能力 |
| Ductility 延展性 | Ability to be drawn into a wire 能够被拉成金属丝的能力 |
| Conductivity 导电性 | Ability to conduct electricity or heat 传导电或热的能力 |
6. Electronic and Mechanical Systems | 电子与机械系统
An engineering system typically consists of an input, a process, and an output. In electronics, inputs include sensors like thermistors and LDRs (light-dependent resistors); processes involve components such as transistors and integrated circuits; outputs might be LEDs, buzzers, or motors. You will learn to use standard circuit symbols and build simple circuits on breadboards. In mechanical systems, levers, gears, pulleys, and linkages transform forces and motion. Study the principle of moments and mechanical advantage—knowing how to balance a lever is a classic engineering problem.
工程系统通常由输入、处理和输出三部分组成。在电子系统中，输入包括热敏电阻和光敏电阻等传感器；处理过程涉及晶体管和集成电路等元件；输出则可能是LED灯、蜂鸣器或电机。你将学会使用标准电路符号并在面包板上搭建简单电路。在机械系统中，杠杆、齿轮、滑轮和连杆机构用来变换力和运动。请学习力矩原理和机械效益——如何平衡杠杆是一个经典的工程问题。
Sum of clockwise moments = Sum of anticlockwise moments
顺时针力矩之和 = 逆时针力矩之和
7. The Engineering Design Process | 工程设计流程
All engineering products begin with identifying a need or problem. The design process involves research, generating ideas, developing a design specification, creating drawings and prototypes, testing, and evaluating. You will use tools like design briefs, mood boards, CAD (Computer-Aided Design) software, and physical modelling to communicate your ideas. Being able to evaluate a design against criteria such as function, aesthetics, cost, and sustainability is a skill you will practise throughout the course.
所有工程产品都始于识别需求或问题。设计流程包括调研、构思创意、制定设计规范、绘制图纸与制作原型、测试以及评估。你将使用设计任务书、情绪板、CAD（计算机辅助设计）软件和实体模型等工具来传达想法。能够根据功能、美观、成本和可持续性等标准来评价设计，是你在整个课程中需要练习的一项技能。
8. Health, Safety, and Risk Assessment | 健康、安全与风险评估
Working safely in a workshop is non-negotiable. Before any practical activity, you must conduct a risk assessment: identify potential hazards, decide who might be harmed, evaluate the level of risk, and implement control measures. Familiarise yourself with common hazard symbols (flammable, toxic, corrosive) and safe working practices, including wearing PPE (personal protective equipment) such as goggles, gloves, and aprons. Learning to use tools like soldering irons, hand saws, and drills correctly will be part of your practical training.
在车间安全地工作是不可妥协的要求。进行任何实践活动之前，你必须进行风险评估：识别潜在危险，判断哪些人可能受到伤害，评估风险等级，并实施控制措施。请熟悉常见的危险符号（易燃、有毒、腐蚀性）以及安全工作规范，包括佩戴护目镜、手套和围裙等个人防护装备（PPE）。正确使用烙铁、手锯和电钻等工具也是实践训练的一部分。
9. Reading Engineering Drawings | 阅读工程图纸
Engineers communicate through technical drawings. You will need to interpret and produce orthographic projections (front, side, and plan views) and isometric drawings. Proper dimensioning, line types, scale, and tolerances are essential for manufacturing. Start practising by sketching simple objects in 2D views and then attempting an isometric projection. Pay attention to title blocks, dimensions, and hidden detail lines. Free software like Tinkercad or SketchUp can help you visualise 3D shapes.
工程师通过技术图纸进行沟通。你需要解读并绘制正投影图（前视图、侧视图和俯视图）以及等轴测图。正确的尺寸标注、线型、比例和公差对于制造至关重要。你可以从用二维视图绘制简单物体开始练习，然后尝试等轴测投影。要注意标题栏、尺寸标注以及隐藏细节线。像 Tinkercad 或 SketchUp 这样的免费软件可以帮助你进行三维形状的可视化。
10. Sustainability in Engineering | 工程中的可持续性
Modern engineering must balance performance with environmental responsibility. The Six Rs (Reduce, Reuse, Recycle, Repair, Refuse, Rethink) offer a framework for sustainable design. You will explore life-cycle assessment, renewable energy systems, and the choice of materials with low carbon footprints. Consider how engineers minimise waste, design for disassembly, and use energy-efficient processes. As you prepare for Year 10, think about the environmental impact of products you use daily.
现代工程必须兼顾性能与环境责任。6R原则（减少使用、重复利用、回收再生、维修、拒绝以及重新思考）为可持续设计提供了一个框架。你将探索生命周期评估、可再生能源系统以及低碳足迹材料的选择。请思考工程师如何最大限度地减少浪费、进行可拆卸设计并使用节能工艺。在你为10年级做准备时，可以想一想你日常使用的产品对环境造成的影响。
11. Mathematical Problem Solving in Context | 情境中的数学问题求解
Engineering problems often require you to combine several mathematical ideas. For example, you might calculate the area of an irregular shape, then use that to find the force exerted by a hydraulic press using pressure = force/area. Or you could use Ohm’s law and Kirchhoff’s voltage law to find unknown resistor values in a circuit. The summer is a great time to practise multi-step word problems that involve unit conversions, percentages, and rearranging equations—skills that appear repeatedly in the exam.
工程问题常常需要你综合运用多种数学知识。例如，你可能会先计算一个不规则形状的面积，然后用压强 = 力/面积公式计算液压机施加的力。或者你可以用欧姆定律和基尔霍夫电压定律来求出电路中未知的电阻值。暑假是练习多步骤应用题的好时机，这些题目涉及单位转换、百分比和方程变形——这些技能在考试中会反复出现。
Pressure = Force ÷ Area (P = F/A)
压强 = 力 ÷ 面积 (P = F/A)
12. Building a Study Routine and Practical Mindset | 建立学习常规与实践思维
To succeed in Engineering, combine consistent theory review with hands-on exploration. Set aside short, focused periods each week to read ahead, watch engineering documentaries, or try a DIY project. Keep a journal where you record observations about how things work—a bicycle brake mechanism, a kitchen mixer, a bridge design. Talk to family members about engineering careers, and perhaps visit a science museum. The most successful students are those who remain curious and are not afraid to make mistakes and learn from them.
要在工程学中取得成功，你需要将一贯的理论复习与亲手实践结合起来。每周留出简短而专注的时间来提前阅读教材、观看工程类纪录片或尝试一个DIY项目。准备一个日记本，用来记录你对事物工作原理的观察——比如自行车刹车装置、厨房搅拌机、桥梁设计。与家人聊一聊工程职业，或许还可以去参观科学博物馆。最成功的学生是那些保持好奇心、不惧犯错并能从中学习的人。
