Moving from primary school to Year 7 brings exciting new subjects, and Engineering is one of the most hands-on and creative disciplines you will encounter. This guide will help you understand what to expect, how to prepare, and how to succeed in your WJEC Engineering course.
从小学升入七年级带来了令人兴奋的新科目，工程学将是你接触到的最具实践性和创造性的学科之一。本指南将帮助你了解课程内容、如何准备以及如何在WJEC工程课程中取得成功。
1. Welcome to Year 7 Engineering | 欢迎来到七年级工程课
Engineering in Year 7 opens the door to a subject where you can design, build and test your own ideas. You will spend time in a dedicated workshop, using real tools and materials to complete projects. The WJEC specification encourages you to think like an engineer from the very start.
七年级工程课为你打开了一扇大门，让你可以设计、建造和测试自己的想法。你将在专业车间里使用真实的工具和材料来完成项目。WJEC教学大纲从一开始就鼓励你像工程师一样思考。
You will keep an engineering logbook to record your designs, sketches, and reflections. This helps you track progress and develops important communication skills. Assessment is often based on your practical work and the quality of your design journal.
你将保留一本工程日志，记录你的设计、草图和反思。这有助于你跟踪进度，并培养重要的沟通技能。评估通常基于你的实践工作和设计日志的质量。
2. What is Engineering? | 什么是工程？
Engineering is the application of science and mathematics to solve problems. Engineers design, create and improve structures, machines, electronic devices, and systems that people use every day. From bridges and cars to smartphones and medical equipment, engineering is everywhere.
工程学是运用科学和数学来解决问题。工程师设计、创造并改进人们日常使用的结构、机器、电子设备和系统。从桥梁和汽车到智能手机和医疗设备，工程无处不在。
There are many branches of engineering, including mechanical, electrical, civil, and chemical engineering. In Year 7, you will sample different areas through practical projects, helping you discover which ones suit your interests.
工程学有许多分支，包括机械工程、电气工程、土木工程和化学工程。在七年级，你将通过实践项目体验不同领域，帮助发现你感兴趣的方向。
3. The Engineering Design Process | 工程设计流程
Every engineer follows a design process to develop successful solutions. The typical stages include: identifying a need, researching, generating ideas, developing a chosen solution, prototyping, testing, and evaluating. In Year 7, you will use this cycle for your own mini-projects.
每位工程师都遵循设计流程来开发成功的解决方案。典型阶段包括：确定需求、研究、产生创意、深化选定方案、制作原型、测试和评估。在七年级，你将运用这个循环来完成自己的小项目。
You will learn to write a clear design brief and specification. A design brief explains what you need to do, while a specification lists the criteria your product must meet, such as size, cost, and materials.
你将学会撰写清晰的设计简介和规格说明。设计简介说明你需要做什么，而规格说明列出你的产品必须满足的标准，例如尺寸、成本和材料。
4. Health and Safety in the Workshop | 工作坊中的健康与安全
Safety is the most important rule in any engineering workshop. Before using any tool or machine, you must understand the correct procedures and wear appropriate personal protective equipment (PPE) such as safety goggles, aprons, and sturdy shoes.
安全是任何工程车间最重要的规则。在使用任何工具或机器之前，你必须了解正确的操作步骤，并佩戴适当的个人防护装备，如护目镜、围裙和结实的鞋子。
Common safety signs you will encounter include mandatory signs (blue circles), prohibition signs (red circles with a line), warning signs (yellow triangles), and emergency exit signs (green rectangles). Always follow your teacher’s instructions and never rush.
你会遇到常见的安全标志，包括指示标志（蓝底圆形）、禁止标志（红圈加斜线）、警告标志（黄底三角形）和紧急出口标志（绿底长方形）。始终遵从老师的指导，切勿匆忙行事。
- Always tie back long hair and remove jewellery.
- 务必扎好长发并摘下首饰。
- Keep your workspace clean and tidy.
- 保持工作区域整洁有序。
- Report any accidents or damaged tools immediately.
- 立即报告任何事故或损坏工具。
5. Materials and Their Properties | 材料及其性质
In Year 7, you will work with a range of materials including wood, metals, plastics, and composites. Understanding their properties helps you select the right material for a design. Key properties include strength, hardness, flexibility, conductivity, and durability.
在七年级，你将接触一系列材料，包括木材、金属、塑料和复合材料。了解它们的性质有助于你为设计选择合适的材料。关键性质包括强度、硬度、柔韧性、导电性和耐久性。
For example, wood is often used for structures because it is easy to shape and environmentally friendly. Metals like aluminium are lightweight and strong, making them ideal for electronics casings. Plastics can be moulded into complex shapes but may lack strength at high temperatures.
例如，木材常用于结构，因为它易于成型且环保。铝等金属轻便且坚固，非常适合用于电子设备外壳。塑料可以塑造成复杂形状，但在高温下可能缺乏强度。
| Material (English) | 材料（中文） | Typical Use | 典型用途 |
|---|---|---|---|
| Pine wood | 松木 | Model structures, furniture | 模型结构、家具 |
| Acrylic (plastic) | 亚克力（塑料） | Display stands, signs | 展示架、标牌 |
| Aluminium | 铝 | Heat sinks, lightweight frames | 散热器、轻质框架 |
| MDF (Medium Density Fibreboard) | 中密度纤维板 | Speaker boxes, flat-pack furniture | 音箱箱体、平板家具 |
6. Basic Tools and Equipment | 基本工具与设备
You will learn to use hand tools safely and accurately. Common tools include the steel rule, try square, coping saw, bench hook, hand drill, and file. Each tool has a specific purpose, and you must hold and operate them correctly.
你将学习安全准确地使用手工工具。常用工具包括钢尺、直角尺、曲线锯、工作台钩、手钻和锉刀。每种工具都有特定用途，你必须正确握持和操作它们。
Measuring and marking out are essential skills. A steel rule gives precise measurements, while a try square helps you draw accurate right angles. Marking out your design before cutting reduces waste and mistakes.
测量和划线是基本技能。钢尺提供精确测量，直角尺帮助画出准确的直角。切割前划线可以减少浪费和错误。
You will also be introduced to simple machines like the pillar drill and strip heater (for bending plastics). Always receive supervision before using any powered equipment.
你还将接触到简单机械，如台钻和带状加热器（用于弯曲塑料）。在使用任何电动设备之前，务必接受监督。
7. Technical Drawing and Sketching | 技术制图与草图
Engineers communicate ideas through drawings. In Year 7, you will begin with freehand sketches, learning to represent 3D objects in 2D using isometric and oblique projections. These skills help you visualise and refine your designs.
工程师通过图纸交流想法。在七年级，你将开始学习徒手草图，学会使用等轴测和斜二测投影在二维平面上表现三维物体。这些技能有助于你可视化和完善设计。
You will also learn orthographic projection, which shows the front, side, and plan views of an object. Adding dimensions correctly ensures that your product can be manufactured accurately.
你还将学习正交投影，展示物体的正面、侧面和平面视图。正确标注尺寸可确保你的产品能够被精确制造。
Use sharp pencils, a ruler, and set squares for neat technical drawings. Labels and material notes complete a professional engineering drawing.
使用尖细的铅笔、尺子和三角板来绘制整洁的技术图纸。标签和材料注释完善了一份专业的工程图纸。
