2. The Engineering Design Process | 工程设计流程
Central to Year 7 engineering is the design cycle: identify a problem, research, generate ideas, develop a chosen solution, make a prototype, test, and evaluate. Students are taught that failure is a learning tool, common in engineering. They keep a design journal to record sketching, annotations, and reflections on how to improve their product.
7 年级工程的核心是设计循环：识别问题、调研、产生构想、开发选定方案、制作原型、测试和评估。学生学习到失败是一种学习工具，在工程中很常见。他们使用设计日志记录草图、注释以及如何改进产品的反思。
An initial project might ask pupils to design a simple bridge from craft materials, meeting a brief of spanning 30 cm and holding a 500 g mass. The process builds skills in brainstorming, justifying choices, and presenting concepts. Edexcel encourages using the ACCESS FM framework (Aesthetics, Cost, Customer, Environment, Size, Safety, Function, Materials) to structure analysis of existing products and their own designs.
一个初始项目可能要求学生用工艺材料设计一座简单桥梁，满足跨度 30 厘米、承重 500 克的简要要求。这个过程培养了头脑风暴、论证选择和展示概念的能力。Edexcel 鼓励使用 ACCESS FM 框架（美学、成本、客户、环境、尺寸、安全性、功能、材料）来系统分析现有产品和自己的设计。
3. Materials and Their Properties | 材料及其性能
Understanding materials is vital for making informed design decisions. Year 7 pupils classify materials into wood, metal, plastic, and composites, exploring characteristics like hardness, toughness, flexibility, and conductivity. They perform simple tests, for example, scratching different plastics or loading wooden beams until fracture, recording outcomes with basic data tables.
理解材料对于做出明智的设计决策至关重要。7 年级学生将材料分为木材、金属、塑料和复合材料，探索硬度、韧性、柔韧性和导电性等特性。他们进行简单的测试，例如刮擦不同塑料或加载木梁直至断裂，并用基本数据表格记录结果。
Key terms are embedded: ductility, malleability, tensile strength, and density. A table like the one below might be used to compare common materials. Pupils learn to select materials for a specific context, such as using softwood for a model frame due to ease of cutting, or acrylic for a phone stand because of its transparency and smooth finish.
学习会嵌入关键术语：延展性、可锻性、抗拉强度和密度。可能使用如下表格比较常见材料。学生学会为特定场景选择材料，例如因易于切割而使用软木制作模型框架，或因透明度和光滑表面而使用亚克力制作手机支架。
| Material | Key Property | Typical Use in Projects |
|---|---|---|
| Pine (softwood) | Light, easy to cut | Frames, structures |
| Aluminium | Low density, corrosion-resistant | Heatsinks, brackets |
| Acrylic | Transparent, brittle | Light covers, displays |
| Cardboard composite | Recyclable, stiff when layered | Prototyping, packaging |
4. Basic Mechanics: Forces and Structures | 基础力学：力与结构
Year 7 introduces essential mechanics without complex mathematics. Students explore forces in equilibrium, learned through building trusses and triangulated frameworks. They experiment with tension and compression using simple springs and soft materials, visualizing how bridges and towers withstand loads. The concept of a moment is briefly introduced using a seesaw model, with calculations limited to Force × Distance.
7 年级引入基础力学，不涉及复杂数学。学生通过搭建桁架和三角框架探索力的平衡。他们使用简单弹簧和软材料做实验，感受拉伸和压缩，直观理解桥梁和塔架如何承受载荷。力矩的概念通过跷跷板模型简要介绍，计算仅限于 力 × 距离。
Key formulas are kept visual and accessible. For example, to calculate the load supported by a beam in a simple structure, pupils may use:
Load on each support = Total Load / Number of Supports
They test spaghetti trusses or straw towers, recording the maximum mass before collapse. This practical work builds an intuitive grasp of structural efficiency and leads to discussions of why triangles are so prevalent in bridge design.
一些关键公式以可视化且易理解的方式呈现。例如，计算简单结构中梁的支撑载荷，学生可能使用：
每个支座的载荷 = 总载荷 / 支座数量
学生测试意大利面桁架或吸管塔，记录倒塌前的最大质量。这种实践操作建立了对结构效率的直观理解，并引发关于为何三角形在桥梁设计中如此普遍的讨论。
5. Introduction to Electronics and Control | 电子与控制入门
Pupils begin electronics by assembling simple circuits on breadboards. They learn the symbols for a cell, switch, resistor, LED, and buzzer, then progress to building a light-sensitive night-light. Ohm’s Law is introduced conceptually, relating voltage, current, and resistance, with a simplified equation:
V = I × R
Where V is voltage in volts (V), I is current in amperes (A), and R is resistance in ohms (Ω). Students take measurements with multimeters, linking theory to real readings.
学生通过面包板组装简单电路开始学习电子学。他们学习电池、开关、电阻、LED 和蜂鸣器的符号，然后逐步搭建一个光敏夜灯。通过概念引入欧姆定律，关联电压、电流和电阻，使用简化公式：
V = I × R
其中 V 为电压（伏特 V），I 为电流（安培 A），R 为电阻（欧姆 Ω）。学生使用万用表进行测量，将理论与实际读数联系起来。
Control systems are introduced via block diagrams and simple flowcharts. A typical project is programming a microcontroller (such as a micro:bit) to flash an LED in response to button presses. This introduces the concept of input, process, output and lays the groundwork for automation and robotics in later years.
控制系统通过框图与简易流程图引入。一个典型项目是编写微控制器（如 micro:bit）程序，使其在按下按钮时闪烁 LED。这引入了输入、处理、输出的概念，为后续年级的自动化和机器人技术打下基础。
6. Technical Drawing and CAD | 技术制图与计算机辅助设计
Accurate communication of ideas is a core engineering skill. Year 7 students learn to produce orthographic drawings (front, side, plan views) to UK conventions, using a drawing board, T-square, and set squares. They practise dimensioning and line weights, developing precision. Isometric drawing is introduced as a method to represent 3D shapes on 2D paper, using a 30° grid.
准确传递想法是一项核心工程技能。7 年级学生学习按照英国规范绘制正投影图（前视图、侧视图、平面图），使用绘图板、丁字尺和三角尺。他们练习尺寸标注和线型粗细，培养精确性。等角投影作为一种在二维纸上表现三维形状的方法被引入，使用 30° 网格。
Alongside manual drawing, pupils begin with CAD software like 2D Design or Tinkercad. They design simple keyrings or flat-pack shapes, which may then be laser-cut or 3D printed. This dual approach shows the value of both hand skills and digital tools in modern engineering workflows.
除了手工绘图，学生开始接触 2D Design 或 Tinkercad 等 CAD 软件。他们设计简单的钥匙扣或平板拼装造型，随后可进行激光切割或 3D 打印。这种双重方法展示了在现代工程工作流程中手工技能和数字工具的双重价值。
7. Manufacturing Techniques and Workshop Safety | 制造工艺与车间安全
Workshop skills form the practical backbone of the course. Pupils are inducted on the safe use of basic hand tools: coping saw, tenon saw, bench hook, sanding block, and files. They practise marking out accurately with a ruler, try square, and marking gauge. The emphasis is on ‘measure twice, cut once’ and maintaining a tidy workspace.
车间技能是课程的实践支柱。学生接受基本手工具的安全使用培训：曲线锯、夹背锯、锯切工作台、打磨块和锉刀。他们练习使用直尺、直角尺和划线规进行精确划线。重点在于“两次测量，一次切割”以及保持整洁的工作区域。
Machine use is limited to teacher-demonstrated equipment at this stage, such as the pillar drill for making perpendicular holes. All operations require personal protective equipment (PPE) – safety goggles and aprons. A risk assessment for each task is written in the student’s workbook, embedding a safety culture early. Simple joining methods like gluing, taping, and using M3 nuts and bolts are covered.
此阶段，机器使用仅限于教师示范的设备，如用于钻垂直孔的台钻。所有操作都要求佩戴个人防护装备（PPE）——护目镜和围裙。每项工作的风险评估会记录在学生的工作手册中，尽早培养安全文化。学习内容包括粘接、胶带连接以及使用 M3 螺母和螺栓等简单连接方式。
8. Project-Based Learning and Assessment | 项目式学习与评估
Assessment in Year 7 Engineering is holistic, mirroring Edexcel’s emphasis on iterative design and making. A typical major project spans a half-term, e.g., ‘Design a moving toy using a cam mechanism’ or ‘Build a sustainable model house with a simple lighting circuit.’ Students produce a portfolio of research, sketches, CAD models, workshop photographs, and a final evaluation.
7 年级工程的评估是整体性的，反映了 Edexcel 对迭代设计和制作的重视。一个典型的大项目历时半个学期，例如“设计一个使用凸轮机构的会动玩具”或“建造带有简单照明电路的可持续房屋模型”。学生需要产出一份包含研究、草图、CAD 模型、车间照片和最终评估的作品集。
Marking criteria are broken down into four strands: Investigating (20%), Designing (30%), Making (30%), and Evaluating (20%). Feedback is given using ‘What Went Well’ and ‘Even Better If’ comments, encouraging a growth mindset. Peer assessment is used regularly, teaching students to critique constructively.
评分标准分为四个方面：调研（20%）、设计（30%）、制作（30%）和评估（20%）。反馈采用“做得好的地方”和“可以更好的地方”的评语形式，鼓励成长型思维。定期开展同伴互评，教导学生进行建设性批评。
9. Developing Engineering Skills | 工程技能培养
Beyond subject content, the course nurtures transferable skills: teamwork, problem-solving, time management, and digital literacy. Through collaborative builds, pupils negotiate roles, share tools, and resolve conflicts. They learn to read and follow technical instructions, interpreting exploded diagrams and step-by-step manuals.
除了学科内容，课程还培养可迁移技能：团队合作、问题解决、时间管理和数字素养。通过协作搭建，学生协商角色、分享工具并解决冲突。他们学会阅读和遵循技术说明，解读部件分解图和分步手册。
Mathematical skills are integrated naturally: measuring with Vernier calipers (±0.5 mm precision), calculating areas for material estimation, and working with ratios for scaling drawings. Literacy is developed through writing design justifications, research summaries, and evaluation reports. A glossary of key terms is built throughout the year, with words like ‘tolerance’, ‘aesthetic’, and ‘ergonomic’ becoming part of active vocabulary.
数学技能被自然地融入：使用游标卡尺进行测量（精度 ±0.5 mm），计算面积以估算材料，以及运用比例缩放图纸。读写能力通过撰写设计理由、研究摘要和评估报告得到发展。全年建立关键术语词汇表，“公差”、“美学”、“人体工学”等词汇成为常用词汇。
10. Sustainability and Ethics in Engineering | 工程中的可持续与伦理
Modern engineering education addresses global challenges. Year 7 pupils discuss the 6Rs: Reduce, Reuse, Recycle, Refuse, Repair, and Rethink. They examine product lifecycles, from raw material extraction to disposal, and are encouraged to choose materials with lower environmental impact in their own projects. A mini-task might involve redesigning packaging to minimise waste.
现代工程教育关注全球挑战。7 年级学生讨论 6R 原则：减量、再利用、回收、拒绝、修理和重新思考。他们审视产品生命周期，从原材料提取到处置，并鼓励在自己的项目中选择环境影响较低的材料。一项小任务可能包括重新设计包装以减少浪费。
Ethical considerations are woven into case studies: fair trade in material sourcing, accessibility in design, and the social responsibility of engineers. For instance, when designing a gadget, pupils must consider users with limited mobility. This instils an early sense that engineering decisions have far-reaching consequences.
伦理考量融入案例研究中：材料采购中的公平贸易、设计中的无障碍性以及工程师的社会责任。例如，设计小工具时，学生必须考虑行动不便的用户。这早早灌输了工程决策具有深远影响的意识。
11. Links to Future Engineering Courses | 与未来工程课程的衔接
Year 7 Engineering sets a strong foundation for the Edexcel Key Stage 3 Design & Technology curriculum and the Level 1/2 BTEC in Engineering. The skills in sketching, CAD, material knowledge, and workshop practice are directly transferable. Pupils who master the iterative design approach will find the transition to GCSE coursework much smoother.
