📚 Year 7 CIE Engineering: Seamless Transition Guide | Year 7 CIE 工程：升学衔接指南
Starting secondary school brings exciting new subjects, and Engineering is one of the most hands-on and creative. In Year 7, you will explore how everyday objects are designed and made, from bridges to electronic gadgets. Engineering combines science, mathematics, and design to solve practical problems and improve lives.
进入初中会接触到许多令人兴奋的新学科，工程学就是其中动手性最强、最具创造力的一门。在 Year 7，你将探索日常物品如何被设计和制造，从桥梁到电子小装置。工程学融合了科学、数学与设计，以解决实际问题、改善人们的生活。
You do not need any prior engineering knowledge; curiosity and a willingness to tinker will take you far. This guide will help you transition smoothly from primary school into the CIE Engineering pathway.
你不需要任何工程学基础；只要拥有好奇心和动手摆弄的意愿，就能走得很远。这份指南将帮助你顺利从小学过渡到 CIE 工程学学习路径。
1. What Engineering Really Looks Like in Year 7 | Year 7 的工程学究竟是什么样的
Engineering in Year 7 is a practical subject built around one simple question: how do we make something that genuinely works for the person who needs it? You will study bridges, bicycle brakes, phone cases and electronic gadgets, take them apart in your mind, and then design your own version.
Year 7 的工程学是一门实践性学科，它建立在一个简单问题之上：我们怎样做出真正适合使用者需要的作品？你会研究桥梁、自行车刹车、手机壳和电子小装置，在脑海中把它们拆解，再设计出自己的版本。
The subject sits at the meeting point of science, mathematics and design. Science explains which forces act and how materials behave, mathematics lets you measure and check your work, and design gives you the freedom to decide what to build and why.
这门学科位于科学、数学与设计的交汇点。科学解释有哪些力在作用、材料如何表现；数学让你测量并检验作品；设计则给你自由，去决定做什么以及为什么这样做。
Because it is a new subject for almost everyone in the class, nobody starts as an expert. Willingness to try, fail, adjust and try again matters far more than any previous experience.
因为对班上几乎所有人来说这都是一门新学科，没有人一开始就是专家。愿意尝试、失败、调整、再尝试，远比过去的任何经验更重要。
2. From Primary to Secondary: What Actually Changes | 从小学到初中：真正改变的是什么
The biggest change is not the difficulty of the work, it is the structure around it. Lessons move to specialist rooms, projects run for several weeks instead of one afternoon, and you are expected to keep your own notes, sketches and materials in order.
最大的变化不是功课的难度，而是围绕功课的结构。课程会搬到专用教室，项目会持续数周而不是一个下午，而且你需要自己管理好笔记、草图与材料。
Mistakes also change meaning. In primary school a mistake often meant a wrong answer; in Engineering a failed prototype is useful evidence that tells you what to change next.
犯错的意义也变了。在小学，错误往往意味着答案不对；在工程学中，失败的原型是有用的证据，它告诉你下一步该改什么。
| Area | 方面 | Primary school | 小学 | Year 7 Engineering | Year 7 工程 |
| Working space | 学习空间 | General classroom | 普通教室 | Workshop, ICT room | 工作坊、信息技术教室 |
| Project length | 项目周期 | One lesson or one day | 一节课或一天 | Two to six weeks | 两到六周 |
| Written record | 书面记录 | Worksheets | 练习纸 | Sketchbook and design portfolio | 速写本与设计作品集 |
| Tools | 工具 | Scissors, glue, card | 剪刀、胶水、卡纸 | Saws, drills, soldering, CAD | 锯、钻、焊接、计算机辅助设计 |
Recognising these differences early lets you prepare instead of being surprised in week one.
早点认清这些差异，你就能提前准备，而不是在第一周被弄得措手不及。
3. The CIE Curriculum for Lower Secondary Engineering | 剑桥初中工程课程框架
The Cambridge Lower Secondary Engineering curriculum is built around the design, make, evaluate cycle. You will learn to identify needs, research existing solutions, generate creative ideas, plan production, and test your prototypes.
剑桥初中工程课程围绕设计 — 制作 — 评估这一循环构建。你将学习如何识别需求、研究现有解决方案、生成创意构想、规划制作并测试原型。
Alongside the practical cycle, the curriculum also covers key theory topics such as materials, mechanisms, and electronics. Theory and practice are deliberately linked: you learn about tensile strength in class, then choose a material for your own bridge.
除了实践循环之外，课程还涵盖材料、机械和电子等关键理论知识。理论与实践的联结是刻意设计的：你在课上学到抗拉强度，随后就为自己的桥梁挑选材料。
By the end of Year 7, you should be able to confidently use basic workshop tools, interpret simple technical drawings, and explain how forces and energy are used in machines. The CIE framework also encourages collaboration and reflection, skills that are essential for future studies.
到 Year 7 结束时，你将能够自信地使用基本工作坊工具、看懂简单的技术图纸，并解释力和能量如何被运用在机器中。CIE 框架还鼓励合作与反思，这些是对未来学习至关重要的技能。
4. The Design, Make, Evaluate Cycle Step by Step | 设计 — 制作 — 评估循环：逐步拆解
Every project follows the same underlying rhythm, and understanding the stages makes coursework far less confusing.
每个项目都遵循同样的内在节奏，理解这些阶段会让课程作业清晰得多。
- Identify the need | 识别需求: who is the user, what problem do they have, and what would success look like?
- Research | 调研: examine existing products, note their strengths and weaknesses.
- Generate ideas | 生成构想: produce several different sketches rather than one perfect one, and annotate each with notes on materials and size.
- Plan | 规划: write a cutting list, choose tools, decide the order of operations, estimate time.
- Make | 制作: build the prototype, measuring accurately and working safely.
- Test and evaluate | 测试与评估: compare the result against the original specification and state what you would change.
- 识别需求：使用者是谁、他们有什么问题、成功的标准是什么？
- 调研：研究现有产品，记下它们的优缺点。
- 生成构想：画出若干个不同方案，而不是一个完美方案，并标注材料与尺寸。
- 规划：写出下料清单、选定工具、确定工序顺序、估算时间。
- 制作：搭出原型，精确测量，安全操作。
- 测试与评估：把成品与原定规格对照，说明你会如何改进。
Teachers mark the thinking as much as the finished object, so keep every sketch, even the ones you rejected.
老师给思考过程的分量不亚于给成品，所以请保留每一张草图，包括被你否掉的那些。
5. Working Safely in the Workshop | 工作坊安全规范
Safety is the first thing you are assessed on and the first thing you must never ignore. Most school workshops use hand tools and low-voltage equipment, but the rules are treated exactly like those in a real factory.
安全是评估你的第一项内容，也是你绝不能忽视的第一件事。多数学校工作坊使用手工工具和低压设备，但执行规则时与真实工厂完全一致。
- Listen to instructions before touching any tool.
- Wear goggles when cutting, drilling or sanding.
- Tie back long hair and remove loose sleeves or jewellery.
- Keep the bench clear and the floor dry.
- Report every cut, burn or broken tool immediately, however small.
- Never use a machine you have not been trained to use.
- 接触任何工具前先听完讲解。
- 切割、钻孔或打磨时必须戴护目镜。
- 束起长发，取下宽松袖口与首饰。
- 保持台面整洁、地面干燥。
- 任何割伤、烫伤或工具损坏都要立刻报告，无论多小。
- 未经培训的机器一律不得使用。
Knowing these rules by heart means you spend your lesson making things instead of being stopped.
把这些规则记牢，你就能把课堂时间用来做东西，而不是被叫停。
6. Materials and Their Properties | 材料及其特性
Choosing a material is one of the most important engineering decisions you will make in Year 7. Properties such as strength, hardness, flexibility, density and cost all push you towards different answers.
选材料是 Year 7 你将做出的最重要工程决定之一。强度、硬度、柔韧性、密度和成本等特性会把你推向不同的答案。
| Material | 材料 | Example | 例子 | Key properties | 主要特性 | Typical use | 常见用途 |
| Softwood | 软木 | Pine | 松木 | Easy to cut, lightweight | 易切割、轻 | Frames, model structures | 框架、模型结构 |
| Metal | 金属 | Aluminium | 铝 | Strong, corrosion resistant, low density | 强度高、耐腐蚀、密度低 | Brackets, bicycle parts | 支架、自行车零件 |
| Polymer | 高分子 | Acrylic | 亚克力 | Transparent, easy to shape with heat | 透明、可热塑成型 | Display cases, guards | 展示盒、防护罩 |
| Smart material | 智能材料 | Thermochromic pigment | 热致变色颜料 | Changes colour with temperature | 随温度变色 | Temperature warnings | 温度警示 |
Always justify a choice with a property, not with personal preference. "Aluminium because it is light and does not rust" is an engineering answer.
选择材料时永远要用特性来论证，而不是用个人喜好。「铝，因为它轻且不生锈」，这才是一个工程学式的答案。
7. Mechanisms and Forces | 机械与力
Mechanisms let a small input create a larger or more useful output. In Year 7 you meet levers, gears, pulleys, cams and linkages, and you learn that each one trades force against distance or speed.
机械让一个小的输入产生更大或更有用的输出。在 Year 7 你会接触到杠杆、齿轮、滑轮、凸轮和连杆，并学到它们都是以力换取距离或速度。
Mechanical advantage = load ÷ effort
F = m × a
Forces act in different ways: tension stretches, compression squeezes, torsion twists, and bending does both at once. A bridge deck, for example, is in compression along its top and tension along its bottom.
力的作用方式各不相同：拉力使物体拉伸，压力使物体压缩，扭转使其旋转，弯折则同时产生拉伸与压缩。以桥面为例，它的上缘受压，下缘受拉。
Energy is the ability to do work, measured in joules (J), and machines never create it. Some input energy always becomes unwanted heat or sound, which is why efficiency is never 100 %.
能量是做功的能力，单位是焦耳（J），机器永远不能创造能量。总有一部分输入能量变成无用的热或声，因此效率永远达不到 100 %。
Efficiency (%) = (useful output energy ÷ total input energy) × 100
8. Electronics and Simple Circuits | 电子与简单电路
Electronics is often the part of Year 7 Engineering that students enjoy most, because a circuit either works or it does not, and you can see why almost immediately.
电子往往是 Year 7 工程学里学生最喜欢的部分，因为电路要么工作要么不工作，而且原因几乎立刻就能看出来。
A simple circuit needs a source, a conductor path, and a load. Typical components you will use include cells, resistors, LEDs, switches and buzzers, joined with crocodile leads or soldered wire.
一个简单电路需要电源、导体通路和负载。你会用到的典型元件包括电池、电阻、发光二极管、开关和蜂鸣器，用鳄鱼夹导线或焊锡线连接。
V = I × R
In a series circuit the current is the same everywhere and the voltages add up; in a parallel circuit the voltage is the same across each branch and the currents add up. LEDs must be connected the right way round, and a resistor protects them from too much current.
在串联电路中各处电流相同、电压相加；在并联电路中各支路电压相同、电流相加。发光二极管必须按正确方向接入，而电阻可以保护它不被过大的电流烧坏。
School circuits use low-voltage cells only. Mains electricity at 230 V is lethal and is never part of a classroom practical.
学校电路只使用低压电池。230 V 的市电会致命，永远不会出现在课堂实验中。
9. Reading and Drawing Technical Drawings | 技术图纸的识读与绘制
Technical drawing is the shared language of engineers. In Year 7 you learn to read orthographic views, showing the front, the plan and the side of an object, and isometric views that show three faces at once.
技术制图是工程师的共同语言。在 Year 7，你学习识读正投影视图（正面、俯视、侧面）以及一次展示三个面的等轴测视图。
Dimensions are always written in millimetres unless stated otherwise, with thin dimension lines and arrowheads. Hidden edges are shown as dashed lines, and centre lines mark the axis of a hole or a shaft.
除非另有说明，尺寸一律以毫米为单位书写，使用细尺寸线和箭头。被遮挡的轮廓用虚线表示，中心线则标出孔或轴的轴线。
Scale tells you how much the drawing has been shrunk or enlarged. A scale of 1:2 means every 1 mm on paper represents 2 mm on the real object.
比例告诉你图纸缩小或放大了多少。1:2 的比例意味着纸上每 1 mm 代表实物 2 mm。
Neat, accurate sketches score higher than elaborate ones, because a drawing that cannot be measured cannot be manufactured.
整洁、准确的草图比花哨的草图得分更高，因为无法测量的图纸就无法被制造出来。
10. Mathematics and Science Skills You Will Use | 会用到的数学与科学技能
Engineering does not ask for advanced mathematics in Year 7, but it does demand that the basics are reliable.
Year 7 的工程学不要求高深数学，但要求基本功足够扎实。
- Area and volume: needed to work out material quantities and cost.
- Ratio and proportion: used constantly in scale drawings and mixing.
- Unit conversion: mm to cm to m, g to kg, minutes to seconds.
- Averages and estimates: useful when testing several prototypes.
- Percentage: used for efficiency and for tolerances.
- 面积与体积：用于计算材料用量与成本。
- 比与比例：在比例制图与配比中反复使用。
- 单位换算：毫米换厘米换米、克换千克、分钟换秒。
- 平均数与估算：测试多个原型时非常有用。
- 百分比：用于效率与公差计算。
From science you will borrow ideas about forces, energy transfer, electrical circuits and the properties of matter. The strongest Year 7 engineers are usually the students who connect their science and mathematics lessons to what happens at the bench.
从科学课你会借用力、能量传递、电路和物质性质等概念。Year 7 最出色的工程学生，往往是把科学课和数学课的内容与工作台上的实际操作联系起来的人。
11. Assessment, Feedback and Portfolio Habits | 评估、反馈与作品集习惯
In CIE Engineering you are assessed on the whole process, not only the final product. Practical work, written design work and your ability to evaluate honestly all contribute to your level.
在 CIE 工程学中，评估覆盖整个过程，而不仅是最终成品。实践操作、书面设计以及你诚实评估的能力，都会影响你的等级。
Formative feedback comes during the project, when a teacher looks at your sketchbook and asks questions. Summative assessment comes at the end of a unit, usually combining a practical outcome with a short written task.
