2. Setting Up the Engineering Environment | 营造工程学习环境
Before any project, establish clear routines for tool handling, storage, and movement. A dedicated ‘tool talk’ at the start of each practical session reduces risk and builds respect for equipment.
在任何项目开始前，需建立清晰的工具使用、存放与移动常规。每次实践课前安排专门的“工具讲解”，可降低风险并培养学生对设备的尊重。
Label all storage clearly and use shadow boards where possible. Create a visual safety charter with students, including rules like ‘no loose hair’, ‘safety glasses on’, and ‘report breakages immediately’.
清晰标记所有储物处，并尽可能使用工具轮廓板。与学生共同制定可视化安全章程，包括“扎好头发”、“佩戴护目镜”和“立即报告破损”等规则。
Set up a ‘making station’ with basic consumables: card, dowel, glue guns, copper tape, LEDs, and batteries. A portable trolley can serve multiple classrooms and keep resources organised.
建立一个配备基础耗材的“制作站”：卡纸、木榫、热熔胶枪、铜胶带、LED 和电池。便携推车可服务多个教室，帮助保持资源有序。
3. Lesson Plan: The Design Process in Action | 教案：设计过程实践
Begin with a one-sentence brief: ‘Design a device to move a marble from table height to the floor in the slowest time.’ Students spend 10 minutes sketching wild ideas individually, then share in pairs to merge concepts.
以一个单句任务简介开始：“设计一个装置，将弹珠从桌面高度送达地面，用时尽可能长。”学生先独立用 10 分钟快速绘制任意想法，然后两人一组分享并融合理念。
Introduce the four-stage cycle: Investigate, Design, Make, Evaluate. Use a large wall poster and let pupils move their name tags to the stage they are in. This makes the process visible and inclusive.
引入四阶段循环：调研、设计、制作、评估。使用大幅墙报，让学生将自己的姓名签移到当前所处阶段。这使流程可视化且具包容性。
After building a prototype from straws and tape, groups test and record descent times. They then modify one feature and retest. This iterative loop becomes a natural habit by the end of the module.
在用吸管和胶带制作原型后，各小组测试并记录下降时间。随后修改一项特征并重新测试。这种迭代循环在模块结束时将成为自然习惯。
4. Exploring Materials and Their Properties | 探索材料及其属性
Set up a sensory investigation table with samples: hardwood, softwood, acrylic, aluminium, copper, nylon, and ceramic. Pupils complete a data sheet noting hardness, flexibility, density, and electrical conductivity.
设置感官探索台，放置样品：硬木、软木、亚克力、铝、铜、尼龙和陶瓷。学生填写数据表，记录硬度、柔韧性、密度和导电性。
Teach key terms such as tensile strength, ductility, and brittleness through simple demos. Stretch a plastic bag to show ductility, snap a pasta piece for brittleness, and hang weights on wire to demonstrate tensile strength.
通过简单演示教授抗拉强度、延展性和脆性等关键术语。拉伸塑料袋展示延展性，折断干意面展示脆性，并在金属丝上悬挂重物演示抗拉强度。
For a quick quiz, place mystery materials in fabric bags and have students identify them by touch and sound alone, linking haptic feedback to property recollection.
进行快速测验时，将神秘材料放入布袋，让学生仅凭触觉和声音辨别，将触感反馈与属性记忆联系起来。
5. Structures and Forces: The Spaghetti Bridge Challenge | 结构与力：意大利面桥挑战
Introduce forces in equilibrium, tension, and compression using body movements: students pull hands apart for tension and push together for compression. This kinaesthetic starter embeds key vocabulary.
通过肢体动作引入平衡力、张力和压力：学生双手拉开表示张力，双手合推表示压力。这种动觉开场活动能嵌入关键词汇。
The challenge: build a bridge spanning 300 mm using only spaghetti and hot glue, capable of holding a 200 g mass at mid-span. Limit materials to 100 g of spaghetti and 2 glue sticks.
挑战：仅用意面和热熔胶建造一座跨度为 300 mm 的桥梁，需在跨中承受 200 g 重物。限制材料为 100 g 意面和 2 根胶棒。
Guide students to draw force arrows on their initial sketches. Encourage triangular trusses by showing images of real bridges. After load-testing, discuss failure modes: buckling, joint failure, or material fracture.
引导学生在其初步草图上绘制受力箭头。通过展示真实桥梁图片鼓励使用三角形桁架。承载测试后，讨论破坏模式：屈曲、节点破坏或材料断裂。

Introduce schematic symbols for battery, switch, LED, and resistor. Have students draw their circuit before building, using rulers. The transfer from 2D drawing to 3D paper circuit reinforces spatial reasoning.
引入电池、开关、LED 和电阻的电路符号。让学生在搭建前用直尺画出电路图。从二维绘图到三维纸电路的转化可强化空间推理能力。
A mini-project: design a light-up book cover with two LEDs and a hidden switch. This merges aesthetics with electronics and provides a tangible take-home product that boosts pride and engagement.
小型项目：设计一个带有两个 LED 和隐藏开关的发光书封。这将美学与电子结合，提供一个可带回家的实物，提升自豪感与参与度。
Use multimeters to measure voltage across the LEDs. Explain forward voltage in simple terms: ‘An LED needs about 2 V to light up; the battery gives 3 V, so we share the extra 1 V with a resistor.’
使用万用表测量 LED 两端的电压。用简单语言解释正向电压：“LED 需要约 2 V 点亮；电池提供 3 V，因此我们用电阻分担多余的 1 V。”
7. Integrating Microcontrollers and Coding | 融合微控制器与编程
Use block-based platforms like the micro:bit or Arduino with simple drag-and-drop programming. Year 7 students can flash an LED using ‘on start’ and ‘digital write’ blocks in the first lesson.
使用 micro:bit 或 Arduino 等基于积木块的平台，配合简单拖放式编程。七年级学生第一堂课便可用“当启动时”和“数字写入”积木块使 LED 闪烁。
Design an alarm system project: when a button is pressed, an LED flashes and a buzzer sounds. Add a servo to create a moving gate. This combines input, processing, and output in a visually rewarding way.
设计一个报警系统项目：按下按钮时，LED 闪烁并触发蜂鸣器。添加舵机制作可移动的门。这样以直观可见的方式整合了输入、处理和输出。
Unplugged activities, such as acting out an ‘if-else’ logic with volunteers, help all learners grasp programming concepts without a screen. It also supports EAL and SEN pupils.
不插电活动，例如请志愿者表演“if-else”逻辑，有助于所有学习者在无屏幕情况下掌握编程概念，也支持英语为附加语言与特殊教育需求学生。
Store completed code versions as incremental files. Teach version control at a basic level: ‘save as v1, v2, v3’. This introduces engineering documentation practice early.
将完成的代码版本存为递进文件。教授基础层面的版本控制：“另存为 v1、v2、v3”。这能及早引入工程文件管理实践。
8. Developing Sketching and Technical Drawing Skills | 培养草绘与技术绘图技能
Begin with freehand 3D sketching: isometric crating using a grid. Show how to draw a simple block phone stand using an isometric grid paper. Celebrate every attempt, focusing on proportion over perfection.
从徒手三维草绘开始：使用网格进行等轴测构架。展示如何利用等轴测网格纸绘制简单的块状手机支架。鼓励每一次尝试，关注比例而非完美。
Move to orthographic projection when students design their final project. Teach front, side, and plan views using cardboard cut-outs as physical aids. This demystifies a key engineering skill.
当学生设计最终项目时，转向正交投影。使用纸板剪裁作为物理辅助，教授前视图、侧视图和平面图。这能揭开关键工程技能的神秘面纱。
Incorporate peer feedback using ‘Two Stars and a Wish’: peers identify two good features and one improvement suggestion for each drawing. This builds a growth mindset vocabulary.
运用“两颗星和一个愿望”进行同伴反馈：同伴为每份图稿指出两个优点和一个改进建议。这能建立成长型思维的表达词汇。
Provide tracing paper overlays to correct or adapt drawings so students see the iterative nature of drafting without the frustration of redrawing everything from scratch.
提供描图纸覆盖层以纠正或调整图纸，这让学生看到草图迭代的本质，无需从头重绘带来挫折感。
9. Cross-Curricular Links and EAL/SEND Differentiation | 跨学科联系与 EAL/SEND 差异化教学
Engineering naturally connects with mathematics (ratio, measurement, graphs), science (forces, energy), and art (aesthetics, form). Design tasks that explicitly refer to these links, such as plotting force-extension graphs from bridge tests.
工程天然与数学（比例、测量、图表）、科学（力、能）和艺术（美学、形式）连接。设计能明确涉及这些联系的任务，例如绘制桥梁测试中的力-延伸图。
For EAL learners, create a picture-based vocabulary wall with terms like ‘chassis’, ‘axle’, ‘gear’, and ‘solder’. Include translations in common home languages and use bilingual buddies during paired work.
对于英语作为附加语言学习者，创建基于图片的词汇墙，包含“底盘”、“轴”、“齿轮”和“焊接”等术语。纳入常见母语翻译，并在结对工作中使用双语伙伴。
For SEND students, offer pre-cut components, simplified briefs, and step-by-step photo instructions. Use colour-coded trays and jigs to reduce fine-motor-skill barriers. Focus on individual progress rather than a fixed standard.
对于特殊教育需求学生，提供预切割组件、简化任务简介和分步照片说明。使用颜色编码托盘和夹具减少精细动作障碍。关注个体进步而非固定标准。
Gifted and talented pupils can extend challenges, such as adding a gear train to a project or automating a function with a sensor, encouraging deeper investigation without leaving the topic behind.
天赋优异学生可延伸挑战，例如为项目添加齿轮组或用传感器实现功能自动化，鼓励深入探究而无需脱离主题。
10. Meaningful Assessment and Feedback Strategies | 有意义的评估与反馈策略
Use a combination of formative checks: exit tickets, design diary scans, and quick soldering quality checks. Give verbal feedback during making, as this is immediate and contextualised.
结合形成性检查：出口票、设计日志扫描和快速焊接质量检查。在制作过程中给予口头反馈，这种方式即时且情境化。
For summative assessment, use a portfolio approach. Students compile their design sketches, annotated photos of prototypes, test data tables, and a short evaluation paragraph. Assess on process, not just final product.
总结性评估采用作品集方式。学生汇编设计草图、带注释的原型照片、测试数据表以及简短评估段落。基于过程而不仅仅是最终产品进行评估。
| Criterion | Evidence | Weight |
|---|---|---|
| Design Iteration | Initial + improved sketches, notes | 25% |
| Making Skills | Photos, teacher observation log | 25% |
| Technical Understanding | Circuit diagrams, force analysis | 25% |
| Evaluation & Reflection | Written reflection, test log | 25% |
Peer assessment using structured criteria sheets empowers students to learn from each other. Train them to use technical language when discussing classmates’ work, which reinforces subject literacy.
使用结构化评分表进行同伴评估，使学生能够互相学习。训练他们在讨论同学作品时使用技术语言，从而强化学科素养。
11. Sample Unit Plan Outline | 单元教学计划概览

根据资源可用性和班级动态调整顺序。部分小组可能需要在进入电子部分前增加一周实践技能学习。
12. Encouraging Reflection and Engineering Habits of Mind | 鼓励反思与工程思维习惯
End each project with a structured reflection: ‘What worked, what didn’t, what would I do differently?’ This develops metacognition and resilience. Use sentence starters for students who find writing challenging.
每个项目结束时进行结构化反思：“哪些有效、哪些无效、我将如何改进？”这能培养元认知与韧性。为写作有困难的学生提供句式开头。
Display a ‘Habits of Mind’ board featuring traits like curiosity, persistence, optimism, and collaboration. Refer to it when praising students, saying ‘I noticed great persistence when you re-soldered that joint three times.’
展示“思维习惯”板，内容包括好奇心、毅力、乐观和协作等品质。在表扬学生时提及它，如“我注意到你在第三次重新焊接那个节点时表现出极大的毅力。”
Invite a local engineer or a parent with a technical role to share their design process. Real-world stories make the habits tangible and show that engineering is a human-centred discipline.
邀请本地工程师或从事技术工作的家长分享其设计过程。真实世界的故事让这些习惯变得具体，并展示工程是以人为本的学科。
Finally, keep a teacher journal of what engaged Year 7 learners most. Reviewing it termly helps refine future planning and builds a bank of evidence for departmental reviews.
