1. Introduction to the WJEC Engineering Course | WJEC 工程课程简介
The WJEC Level 1/2 Engineering qualification is designed to give you a broad introduction to the world of engineering. It combines theoretical knowledge with practical hands-on experience, preparing you for further study or a career in the sector. The course is typically taught over two years, with Year 10 covering foundational principles and initial project work.
WJEC 1/2 级工程资格证书旨在让你全面了解工程世界。它把理论知识与动手实践经验相结合，为你继续深造或进入该行业就业做好准备。课程通常在两年的时间里教授，Year 10 主要涵盖基础原理和初步的项目任务。
You will explore how engineers solve real-world problems, from designing sustainable products to manufacturing components with precision. The syllabus is structured around three mandatory units: Engineering Design, Producing Engineering Products, and Solving Engineering Problems. Each unit contributes to your final grade in a different way.
你将探究工程师如何解决现实世界的问题，从设计可持续产品到精密制造零部件。课程大纲围绕三个必修单元构建：工程设计、制造工程产品以及解决工程问题。每个单元以不同方式计入你的最终成绩。
Throughout Year 10, you will develop skills in researching, planning, drawing, making prototypes, and evaluating your work. You will also learn about the importance of health and safety, materials science, and electronic and mechanical systems. This integrated approach ensures you build a solid foundation for Year 11 and beyond.
在 Year 10 的整个学习过程中，你将培养研究、规划、绘图、制作原型以及评估自己作品的能力。你还会学到健康与安全、材料科学以及电子与机械系统的重要性。这种综合性方法能确保你为 Year 11 及以后的学习打下扎实的基础。
2. Unit 1: Engineering Design – Core Principles | 单元一：工程设计——核心原则
Unit 1 focuses on the design process, which lies at the heart of all engineering activity. You will learn how to analyse a design brief, identify user needs, and write a clear design specification. This unit is externally assessed through a written examination, making up 25% of the qualification.
单元一侧重于设计流程，这是所有工程活动的核心。你将学习如何分析设计概要、确定用户需求并撰写清晰的设计规格。本单元通过书面考试进行外部评估，占总成绩的 25%。
You will explore techniques for generating creative ideas, such as brainstorming, morphological analysis, and SCAMPER. Once ideas are generated, you need to select the most viable solution using criteria like functionality, aesthetics, cost, and sustainability. Sketching and annotation are essential skills at this stage.
你将探索产生创意的技巧，如头脑风暴、形态分析法和 SCAMPER 法。产生想法后，你需要根据功能、美观、成本和可持续性等标准选择最可行的方案。草图绘制和标注是这个阶段的基本技能。
Engineering drawings are a key part of this unit. You must be able to produce both 2D orthographic projections and 3D isometric sketches. Understanding dimensions, scale, and line types (e.g., construction lines, outlines, hidden detail) is crucial. CAD software may be used, but the exam often tests your ability to interpret and create drawings by hand.
工程图样是本单元的关键部分。你必须能够绘制二维正交投影和三维修正等距草图。理解尺寸、比例和线型（如构造线、轮廓线、隐藏细节线）至关重要。虽然可能使用 CAD 软件，但考试通常考查你手绘和解读图纸的能力。
You will also learn to evaluate designs against the specification and consider how products can be improved. Sustainability, including the 6 R’s (Reduce, Reuse, Recycle, Repair, Refuse, Rethink), is a recurring theme. Understanding customer feedback and testing prototypes will help you develop iterative design skills.
你还将学习对照设计规格评估设计方案，并思考如何改进产品。可持续性，包括 6R 原则（减量、重用、回收、修复、拒绝、再思考），是一个反复出现的主题。理解客户反馈和原型测试将帮助你培养迭代设计能力。
3. Unit 2: Producing Engineering Products – Practical Skills | 单元二：制造工程产品——实践技能
Unit 2 is the practical coursework component, accounting for 50% of your overall grade. In Year 10, you will typically begin a series of mini-projects or skill-building tasks that lead to a final manufactured product. You will work with a range of materials, including metals, polymers, and woods.
单元二是实践课程作业部分，占总成绩的 50%。在 Year 10，你通常会开始一系列小项目或技能培养任务，最终制成一件成品。你将使用多种材料，包括金属、聚合物和木材。
You will learn to mark out and measure accurately using tools like steel rules, try squares, scribers, and centre punches. Cutting, shaping, and finishing techniques are essential.

Joining methods are a core part of manufacturing: you could use adhesives, nuts and bolts, screws, rivets, or soft soldering. You must be able to select the appropriate joining technique based on materials, strength required, and whether the product needs to be disassembled. Safe working practices are assessed throughout, including the use of personal protective equipment (PPE) and risk assessments.
连接方法是制造的核心部分：你可以使用粘合剂、螺母和螺栓、螺钉、铆钉或软钎焊。你必须能够根据材料、所需强度以及产品是否需要拆卸来选择合适的连接技术。在整个过程中，安全工作规范都会被评估，包括使用个人防护装备和风险评估。
Quality control is emphasised. You will learn to use vernier callipers, micrometres, and go/no-go gauges to check dimensions. Your coursework portfolio will include photographs, process plans, and evaluation of your final product against the original design specification. Attention to detail and craftsmanship are key to achieving high marks.
质量控制受到重视。你将学习使用游标卡尺、千分尺和通止规来检查尺寸。你的课程作业作品集将包含照片、流程计划以及对照最初设计规格对成品进行的评估。注重细节和工艺水平是取得高分的关键。

5. Materials in Engineering | 工程材料
A thorough understanding of materials is essential across all three units. You will classify materials into families: ferrous metals (e.g., mild steel, cast iron), non-ferrous metals (e.g., aluminium, copper, brass), alloys (e.g., stainless steel), polymers (thermoplastics and thermosetting plastics), wood (hardwoods, softwoods, manufactured boards), and composites (e.g., carbon fibre, GRP).
在所有三个单元中，对各种材料透彻理解都是必不可少的。你会将材料分类为几大类：黑色金属（如低碳钢、铸铁）、有色金属（如铝、铜、黄铜）、合金（如不锈钢）、聚合物（热塑性和热固性塑料）、木材（硬木、软木、人造板）和复合材料（如碳纤维、玻璃钢）。
For each material, you should know typical engineering applications, advantages, and disadvantages. For example, aluminium is lightweight and corrosion-resistant, making it ideal for aircraft bodies, but it is more expensive than mild steel. Thermoplastics can be recycled and reshaped when heated, unlike thermosets which cannot be remoulded.
对于每种材料，你都应该了解典型的工程应用、优点和缺点。例如，铝重量轻且耐腐蚀，非常适合用于飞机机身，但比低碳钢贵。热塑性塑料加热后可以回收并重塑形状，而热固性塑料则不能重新模塑。
Material properties are tested through physical and mechanical methods. You need to describe hardness tests (e.g., Brinell, Rockwell), tensile tests, and toughness tests (e.g., Izod impact test). The relationship between the internal structure of a material and its properties, such as grain size in metals, is also relevant.
材料特性通过物理和机械方法进行测试。你需要描述硬度试验（如布氏硬度、洛氏硬度）、拉伸试验和韧性试验（如艾氏冲击试验）。材料的内部结构与其性能之间的关系，比如金属的晶粒大小，同样有关联。
Choosing the right material for a design involves trade-offs. You will learn to use selection charts and databases, and to justify your choices based on mechanical properties, cost, availability, environmental impact, and aesthetics. This is a recurring task in both the design and practical units.
为设计选择合适的材料涉及权衡取舍。你将学习使用选择图表和数据库，并根据机械性能、成本、可获得性、环境影响和美观性来论证你的选择。这是设计单元和实践单元中反复出现的任务。
6. Manufacturing Processes | 制造工艺
Year 10 WJEC Engineering introduces a wide range of manufacturing processes. You will learn to distinguish between primary processes (creating basic shapes from raw materials) and secondary processes (refining shapes and adding features). Understanding the capabilities and limitations of each process is vital for design and production.

9. Health, Safety and Sustainability | 健康、安全与可持续性
Health and safety are not a separate topic but are embedded throughout the course. You must be able to identify hazards in an engineering workshop and suggest suitable control measures. Risk assessments, following the 5-step model (Identify hazards, decide who might be harmed, evaluate risks, record findings, review), are a key part of your practical work.
健康与安全并非一个独立的主题，而是贯穿整个课程。你必须能够识别工程车间中的危险，并提出合适的控制措施。风险评估遵循五步模型（识别危险、确定可能受影响的人员、评价风险、记录结果、审查），是你实践工作的关键部分。
Relevant legislation includes the Health and Safety at Work Act (HASAWA), the Control of Substances Hazardous to Health (COSHH), and the Personal Protective Equipment at Work Regulations. You will learn about the correct disposal of waste materials, especially hazardous substances like solvents and electronic waste.
