By the end of Year 7, learners should be able to follow the engineering design cycle, select appropriate materials for a given task, and evaluate their own work against a specification.
课程通常贯穿一个学年，包含一小时的常规理论课和双倍时长的实践操作课。各关键主题以模块形式组织，将知识获取与动手制作相结合。到 Year 7 结束时，学生应能遵循工程设计循环，为特定任务选择合适的材料，并根据设计规格评价自己的作品。
Key Aims: Investigate → Design → Make → Evaluate
核心目标：调研 → 设计 → 制作 → 评估
2. The Engineering Design Process | 工程设计流程
At the heart of the curriculum is the iterative design process – a cycle of researching, generating ideas, prototyping, testing, and refining. Students learn that engineering is rarely linear; instead, they are encouraged to revisit earlier stages based on testing feedback. This mirrors real-world practices in product design and mechanical engineering. The process begins with a design brief and a detailed product analysis of existing solutions, helping learners understand user needs and functional requirements.
课程的核心是迭代设计过程——一个包含调研、方案生成、原型制作、测试和改进的循环。学生认识到工程绝不是线性的；相反，他们被鼓励根据测试反馈不断回溯早期阶段。这与产品设计和机械工程中的实际做法完全一致。过程从设计任务书以及对现有解决方案的详细产品分析开始，帮助学生理解用户需求和功能要求。
Sketching and drawing skills are emphasised weekly. Freehand isometric and orthographic projection techniques are introduced so that pupils can communicate three-dimensional forms on paper. Basic computer-aided design (CAD) using software such as Tinkercad or Fusion 360 is also incorporated, allowing students to create digital models and prepare files for 3D printing or laser cutting. Annotation and dimensioning are taught to ensure drawings are precise and informative.
每周都会强调素描和绘图技能。课程引入徒手等角视图和正交投影技法，以便学生能在纸面上表现三维形态。同时还融入使用 Tinkercad 或 Fusion 360 等软件的基础计算机辅助设计（CAD），让学生创建数字模型并为 3D 打印或激光切割准备文件。教授标注和尺寸以保绘图精准、信息充分。
3. Materials and Their Properties | 材料及其性能
Understanding materials is fundamental to all engineering disciplines. In Year 7, students explore the main classes of materials: woods, metals, polymers, composites, and smart materials. They learn to differentiate between natural and manufactured timbers, ferrous and non-ferrous metals, and thermoplastics versus thermosetting plastics. Hands-on testing of hardness, ductility, toughness, and conductivity helps pupils link measurable properties to suitability for specific applications.
理解材料是所有工程学科的基础。在 Year 7，学生将探索主要的材料类别：木材、金属、聚合物、复合材料和智能材料。他们学习区分天然木材与人造木料、黑色金属与有色金属，以及热塑性塑料与热固性塑料。通过动手测试硬度、延展性、韧性和导电性，学生将可量化的性能与特定应用的适用性联系起来。
A typical lesson might involve a 'material detective' activity where samples are examined, weighed, subjected to a scratch test, and exposed to moisture. Pupils record their observations in an engineering notebook and then use a simple database to compare properties. The following table summarises common materials covered in the syllabus:
典型的一课可能包含“材料侦探”活动：对样本进行观察、称重、划痕测试并暴露于潮湿环境。学生在工程笔记中记录观察结果，然后用简易数据库比较性能。下表总结了课程大纲中涉及的常见材料：
| Material | Classification | Key Property | Typical Use |
|---|---|---|---|
| Pine | Softwood | Light, easy to cut | Furniture frames |
| Mild steel | Ferrous metal | Strong, magnetic | Nuts and bolts |
| Acrylic | Thermoplastic | Impact resistant | Display signs |
| Shape-memory alloy | Smart material | Returns to original shape when heated | Thermostats, actuators |
The concept of sustainability is introduced here, too: students discuss the environmental impact of extracting raw materials and the importance of recycling and reusing engineering products. They are encouraged to select materials with lower carbon footprints in their own design projects.
此处也引入了可持续性概念：学生讨论原材料开采的环境影响以及回收和再利用工程产品的重要性。他们被鼓励在自己的设计项目中选择碳足迹更低的材料。
4. Workshop Safety and Basic Tools | 工坊安全与基本工具
Before any making can begin, learners must demonstrate a thorough understanding of health and safety in the workshop. The curriculum covers personal protective equipment (PPE), safe handling of cutting tools, and emergency procedures. Pupils sign a 'safety contract' after passing a written and practical assessment that includes identifying hazards and selecting the correct safety measure for a given scenario.
在开始任何制作之前，学生必须证明对工坊健康与安全有全面理解。课程内容涵盖个人防护装备（PPE）、切割工具的安全操作以及应急程序。学生通过书面和实践评估后签署一份“安全约定”，评估内容包括识别危险源以及为给定情景选择正确的安全措施。
Tool familiarisation starts with measuring and marking instruments: steel rules, try squares, scribers, and marking gauges. Cutting and shaping are introduced with junior hacksaws, files, abrasive papers, and hand drills. For each tool, students learn its correct name, purpose, and maintenance routine. The 'Tool of the Week' approach ensures deep familiarity before moving on. Adopting correct posture and securing workpieces with a vice or clamp is non-negotiable.
工具熟悉从量具和划线工具开始：钢尺、直角尺、划线针和划线规。接着引入切割与塑形工具，包括小手锯、锉刀、砂纸和手钻。对每件工具，学生都要学习其正确名称、用途和保养规程。“每周一工具”教学法确保在他们进阶前对工具完全熟悉。采用正确姿势并用台钳或夹具固定工件绝对没有商量余地。
5. Manufacturing Techniques | 制造技术
nents accurately, cut with a tenon saw, smooth edges with a file, and bend thin metal or plastic using a strip heater. Joining methods include using PVA adhesive for timber, applying epoxy resin for mixed-material bonds, and constructing bolted assemblies. Emphasis is placed on producing work that meets given tolerances, often within ±1 mm.
Year 7 学生将接触一系列将原材料转变为成品零件的制造工艺。他们学习如何精确划线下料，用夹背锯切割，用锉刀修光边缘，以及使用条带加热器弯折薄金属或塑料。连接方法包括给木料使用 PVA 胶，为异质材料粘接使用环氧树脂，以及构建螺栓紧固组件。重点在于制作出满足给定公差（通常在 ±1 mm 以内）的作品。
Pupils complete a focused practical task, such as manufacturing a small phone stand or a mechanical toy. This project integrates multiple skills: measuring, cutting, drilling, and surface finishing with wet-and-dry paper. The quality of finish is assessed through visual inspection and a simple functional test. Learners are taught to use a production plan, which lists sequential steps, tools, and quality checks – a vital skill for future engineering qualifications.
学生需完成一项集中的实践任务，例如制作一个小型手机支架或机械玩具。该项目整合多种技能：测量、切割、钻孔以及用干湿砂纸进行表面精加工。成品质量通过目检和简易功能测试加以评估。学生要学习使用生产计划表，列出顺序步骤、工具和质量检查点——这对未来工程资格证书而言是至关重要的技能。
6. Introduction to Electronics | 电子学入门
Electronics is made accessible through simple circuit-building activities. The syllabus covers the basic components: batteries, switches, light-emitting diodes (LEDs), resistors, and buzzers. Students learn to identify schematic symbols and to construct circuits on breadboards before soldering onto stripboard. The relationship between voltage, current, and resistance is introduced conceptually; Year 7 pupils are taught that increasing resistance reduces current flow, and they observe this by swapping resistors in a simple LED circuit.
通过简单的电路搭建活动让电子学变得通俗易懂。课程大纲涵盖基本元器件：电池、开关、发光二极管（LED）、电阻器和蜂鸣器。学生学会识别原理图符号，并在面包板上搭建电路，然后再焊接到条形板上。课程以概念化方式引入电压、电流与电阻的关系；Year 7 学生将知道增大电阻会减小电流，并通过在简单 LED 电路中更换电阻器来观察这一现象。
Polarity and the function of a diode are demonstrated with a 'red/black lead' rule. Learners build series and simple parallel circuits, measure voltages using a multimeter, and record results in a logbook. A design-and-make task might involve creating a steady-hand game or a light-sensitive night-light. Although calculations are not heavily emphasised, the concept of Ohm's law is sometimes visualised using the formula triangle:
通过“红黑表笔”规则演示二极管的极性和功能。学生搭建串联和简单并联电路，用万用表测量电压，并在日志中记录结果。一项设计制作任务可能包括制作一个稳手游戏或一个光敏小夜灯。尽管不特别强调计算，但有时会用公式三角图示直观展现欧姆定律的概念：
V = I × R (Voltage = Current × Resistance)
V = I × R （电压 = 电流 × 电阻）
7. Mechanical Systems and Motion | 机械系统与运动
Mechanical principles are explored through levers, linkages, pulleys, and gears. Students begin by classifying simple levers (Class 1, 2, and 3) and identifying the load, effort, and fulcrum in everyday objects such as scissors, wheelbarrows, and tweezers. Mechanisms like the crank and slider and rack and pinion are built using construction kits, allowing pupils to translate rotary motion into linear motion and vice versa.
通过杠杆、连杆、滑轮和齿轮来探索机械原理。学生首先对简单杠杆进行分类（一类、二类和三类），并辨识剪刀、手推车和镊子等日常物品中的负载、施力点及支点。利用搭建套件构建曲柄滑块机构和齿轮齿条机构，让学生亲身体验如何将旋转运动转化为直线运动，反之亦然。
Gear trains offer an opportunity to discuss speed, torque, and mechanical advantage. Simple calculations of gear ratios are introduced: for a pair of meshing gears, the velocity ratio is the number of driven gear teeth divided by the number of driver gear teeth. Learners test their predictions by building gear trains and counting output revolutions per minute. This hands-on approach makes abstract mathematical relationships tangible.
齿轮轮系提供了讨论速度、扭矩和机械效益的机会。课程引入简单的齿轮比计算：对于一对啮合齿轮，速度比等于从动轮齿数除以主动轮齿数。学生通过搭建齿轮轮系并计数每分钟输出转速来验证自己的预测。这种动手方式使抽象的数学关系变得切实可感。
Output Revolutions = Driver Revolutions × (Tdriver ÷ Tdriven)
输出转速 = 主动轮转速 × （主动轮齿数 ÷ 从动轮齿数）
8. Structural Engineering and Forces | 结构工程与力
Pupils investigate how structures bear loads and resist failure. Concepts covered include tension, compression, shear, and torsion, as well as bending and buckling. Through simple experiments with paper tubes, spaghetti bridges, and modelling clay, learners discover how cross-sectional shape (I-beams, triangular trusses) distributes stress and enhances strength-to-weight ratio. The importance of triangulation in frame structures is a memorable practical lesson.
学生将研究结构如何承受载荷并抵抗失效。涵盖的概念包括拉伸、压缩、剪切、扭转，以及弯曲和屈曲。通过纸管、意大利面条桥和油泥模型的简单实验，学生发现截面形状（工字梁、三角桁架）如何分散应力并提高强度重量比。框架结构中三角加固的重要性是一堂令人难忘的实践课。
iddle. Year 7 pupils are not required to solve complex equations, but they are taught to use the idea that force × distance from support equals a torque that must be balanced. They test their structures to destruction and record the maximum load, which feeds into an evaluation report.
简单计算有助于量化载荷分布。例如，梁两端支撑时，最大弯矩出现在中间。不要求 Year 7 学生求解复杂方程，但他们会学习运用如下观念：力 × 距支撑点的距离等于一个必须平衡的力矩。他们将结构测试至破坏并记录最大载荷，这将成为评估报告的一部分。
9. Sustainability and Environmental Engineering | 可持续性与环境工程
Engineering has a profound impact on the planet, and the Year 7 syllabus addresses this responsibility directly. Students explore the 6Rs of sustainability: Reduce, Reuse, Recycle, Rethink, Refuse, and Repair. Case studies include the life cycle analysis of a plastic bottle versus a reusable metal flask, and the design choices behind modular smartphones. Pupils are asked to calculate the carbon footprint of a simple product and propose design improvements to minimise environmental harm.
工程对地球有深远影响，Year 7 课程大纲直接面向这一责任。学生探讨可持续发展的 6R 原则：减少、重用、回收、再思考、拒绝、修复。案例研究包括塑料瓶与可重复使用金属水瓶的生命周期分析，以及模块化智能手机背后的设计选择。学生被要求计算一件简单产品的碳足迹，并提出最小化环境损害的设计改进建议。
Renewable energy technologies are introduced at a foundational level. Pupils build simple wind turbines or solar-powered models and measure electrical output. Discussions cover the trade-offs between renewable and non-renewable sources, linking back to material selection and manufacturing energy. The notion of 'design for environment' permeates project briefs, encouraging students to justify every material and process choice in their portfolios.
在基础层面介绍可再生能源技术。学生搭建简易风力涡轮或太阳能模型并测量电输出。讨论涵盖可再生与不可再生能源之间的利弊权衡，并关联到材料选择和制造能耗。“面向环境的设计”理念贯穿项目任务书，鼓励学生在作品集中为每一次材料与工艺决策提供理由。
10. Assessment Structure and Grading | 评估结构与评分
Assessment in Year 7 OCR Engineering is ongoing and multi-faceted, designed to capture both theoretical understanding and practical competence. Typically, the final grade is derived from three components: a design portfolio (40%), a practical making task (40%), and an end-of-year written exam (20%). The portfolio documents the entire design journey – from initial research and specification to development sketches, CAD models, and final evaluation against criteria.
Year 7 OCR 工程的评估持续进行且多维度展开，旨在同时考核理论理解与实践能力。通常，最终成绩由三个部分组成：设计作品集（40%）、实践制作任务（40%）和年终书面考试（20%）。作品集记录整个设计历程——从初步调研和设计规格，到方案发想草图、CAD 模型，再到对照标准的最终评价。
The practical task is assessed on accuracy, finish quality, safe working practices, and the ability to follow a production plan. Teachers use a simple rubric: precision (tolerance band), surface finish (burr-free, smooth), structural integrity, and overall functionality. The written examination consists of multiple-choice, short-answer, and extended response questions. Topics are drawn from all modules and often require students to interpret diagrams or suggest suitable materials for a given context.
实践任务的评分依据为加工精度、表面质量、安全操作以及遵循生产计划的能力。教师使用一份简易评分标准：精密（公差范围）、表面光洁度（无毛刺、光滑）、结构完整性和整体功能。书面考试包含选择题、简答题和论述题。题目覆盖所有模块，常要求学生解读图表或为特定情境推荐合适材料。
| Assessment Component | Weighting | Focus |
|---|---|---|
| Design Portfolio | 40% | Research, sketching, CAD, evaluation |
| Practical Task | 40% | Accuracy, finish, safety, plan |
| Written Exam | 20% | Theory, problem-solving |
11. Learning Resources and Study Tips | 学习资源与备考技巧
