1. Introduction to Engineering | 工程入门
Engineering is the creative use of science and mathematics to solve real-world problems. Engineers design, build, test, and improve products, systems, and structures. The four main branches are civil, mechanical, electrical, and software engineering, but many modern projects combine them all. Whether it is a wind turbine, a water filtration system, or a smartphone, engineers follow a process to turn ideas into reality safely and efficiently.
工程是科学和数学的创造性应用，旨在解决现实世界的问题。工程师设计、建造、测试并改进产品、系统和结构。四大主要分支是土木工程、机械工程、电气工程和软件工程，但许多现代项目将它们全部结合起来。无论是风力发电机、净水系统还是智能手机，工程师都遵循一套流程，将想法安全高效地变为现实。
Engineering has shaped human history. The pyramids, Roman aqueducts, steam engines, and the internet all came from engineering mindsets. Today's challenges—climate change, clean water supply, and sustainable cities—demand a new generation of problem solvers. In Year 7, you will start thinking like an engineer by tackling small design tasks and learning how to work with materials, tools, and digital technology.
工程塑造了人类历史。金字塔、罗马引水渠、蒸汽机和互联网都源于工程思维。当今的挑战——气候变化、清洁水供应和可持续城市——需要新一代的问题解决者。在七年级，你将通过完成小的设计任务，并学习如何使用材料、工具和数字技术，开始像工程师一样思考。
2. The Engineering Design Process | 工程设计流程
The design process is a step-by-step method engineers use to solve problems. It starts with defining the problem and doing research. Then comes brainstorming and sketching possible solutions. Next, the best idea is chosen and developed into a detailed design. A prototype is built and tested to see if it works. Based on testing results, the design is improved. This cycle of test and improve is called iteration.
设计流程是工程师用来解决问题的一套分步方法。它从定义问题并进行研究开始。然后是头脑风暴并绘制可能的解决方案草图。接下来，选出最佳想法并将其发展为详细设计。制作原型并进行测试，看它是否有效。根据测试结果改进设计。这种测试与改进的循环称为迭代。
In Year 7, you will learn to write a simple design brief and specifications. You might design a bridge from spaghetti or a glider from card. You will realise that failing early is part of succeeding, because each mistake teaches you something valuable. Documenting your steps and reflections is just as important as the final product. Always ask: 'What have I learned?' and 'How can I make it better?'
在七年级，你将学习撰写简单的设计摘要和规格说明。你可能会用意大利面条设计一座桥，或用卡纸设计一架滑翔机。你会意识到，早期失败是成功的一部分，因为每一次错误都能让你学到宝贵的东西。记录你的步骤和反思与最终产品同样重要。始终问自己：“我学到了什么？”以及“如何才能做得更好？”
3. Workshop Safety | 工作坊安全
Safety is the number one rule in any engineering workshop. Before you touch any tool or machine, you must understand the risks and wear the correct personal protective equipment (PPE). This usually includes safety goggles, an apron, and sometimes gloves or ear defenders. Hair must be tied back, loose clothing secured, and bags kept out of walkways to prevent trips and tangling.
安全是任何工程工作坊的首要规则。在你接触任何工具或机器之前，必须理解相关风险并穿戴正确的个人防护装备（PPE）。这通常包括安全护目镜、工作围裙，有时还需戴手套或听力保护器。头发必须扎起来，宽松的衣物要固定好，书包要远离走道，以防绊倒和卷入。
You will learn to read hazard symbols on materials and equipment. For example, a flame symbol means flammable, and an exclamation mark signals general caution. Always listen carefully when a teacher demonstrates a tool. Never rush or mess about. Clean up your workspace and report any damage or spills immediately. Good safety habits protect you and everyone around you, and they are the foundation of professional engineering.
你将学会阅读材料和设备上的危险标志。例如，火焰符号表示易燃，感叹号表示一般警告。老师演示工具时一定要仔细听。切勿匆忙或打闹。清理工作区域，并立即报告任何损坏或溢出物。良好的安全习惯能保护你和周围的每一个人，这是专业工程的基础。
4. Tools and Equipment | 工具与设备
Young engineers get hands-on with many different tools. Hand tools such as saws, files, screwdrivers, and pliers are used to cut, shape, and join materials. Measuring and marking tools like steel rules, try squares, and callipers help ensure accuracy. In the workshop you might also meet pillar drills, hot glue guns, and strip heaters for bending plastics.
年轻工程师要动手使用许多不同的工具。手锯、锉刀、螺丝刀和钳子等手工工具用于切割、塑形和连接材料。钢尺、直角尺和卡尺等测量与划线工具有助于确保精度。在工作坊中，你还可能接触到台钻、热熔胶枪和用于弯曲塑料的带加热器。
Using tools correctly takes practice and patience. Always clamp your work firmly before cutting or drilling. Saw away from your body and keep your fingers clear of sharp edges. Below is a quick reference table of common workshop tools and their main uses:
正确使用工具需要练习和耐心。在切割或钻孔之前，一定要把工件夹紧稳固。锯子要朝远离身体的方向锯，手指要远离锋利边缘。下面是常见工作坊工具及其主要用途的快速参考表：
| Tool | 用途 | Tool (English) | Use |
|---|---|---|---|
| 手锯 | 直线切割木材或塑料 | Hacksaw | Straight cuts in wood or plastic |
| 平锉 | 磨平金属或塑料边缘 | Flat file | Smoothing edges of metal or plastic |
| 热熔胶枪 | 快速粘合多种材料 | Hot glue gun | Quick bonding of various materials |
| 钢尺 | 精确测量和划线 | Steel rule | Accurate measuring and marking |
5. Materials and Their Properties | 材料及其特性
Choosing the right material is crucial in any engineering project. Materials are grouped into categories: natural woods, manufactured boards, ferrous and non-ferrous metals, plastics, ceramics, and composites. Each material has a set of properties like hardness, toughness, flexibility, conductivity, and density. A bridge needs high tensile strength, while a phone case needs to absorb impacts.
在任何工程项目中，选择合适的材料都至关重要。材料可分为几类：天然木材、人造板材、黑色金属和有色金属、塑料、陶瓷和复合材料。每一种材料都有一系列特性，如硬度、韧性、柔韧性、导电性和密度。桥梁需要高拉伸强度，而手机壳则需要能吸收冲击。
In Year 7, you will test materials by stretching, bending, and observing them under heat. Some useful terms include: ductility (being able to be drawn into wire), brittleness (snapping without much bending), and thermal conductivity (how heat travels through it). The table below shows a few materials and their key properties:
在七年级，你将通过拉伸、弯折和加热观察来测试材料。一些有用的术语包括：延展性（能被拉成丝）、脆性（在没有太多弯曲的情况下断裂）以及导热性（热量在其中的传递方式）。下表展示了几种材料及其关键特性：
| 材料 (Material) | 特性 (Property) | 汉语解释 |
|---|---|---|
| 松木 (Pine) | Light, easy to cut, fairly strong | 轻质，易切割，相当坚固 |
| 铝 (Aluminium) | Light, corrosion-resistant, ductile | 轻质，耐腐蚀，有延展性 |
| 有机玻璃 (Acrylic) | Transparent, brittle, can be heat-shaped | 透明，脆，可热塑成形 |
| 低碳钢 (Mild steel) | Strong, magnetic, can rust | 坚固，有磁性，会生锈 |
6. Structures and Forces | 结构与力
Structures are everywhere: towers, tunnels, chairs, and even your own skeleton. A structure must support loads without breaking or bending too much. Engineers think about tension (stretching force), compression (squashing force), shear, torsion, and bending. When a beam bends, the top surface experiences compression while the bottom surface is in tension.
结构无处不在：塔楼、隧道、椅子，甚至你自己的骨架。结构必须能够支撑载荷，而不会断裂或过度弯曲。工程师要考虑拉力（拉伸力）、压力（压缩力）、剪切力、扭转力和弯曲力。当梁弯曲时，上表面承受压力，而下表面承受拉力。
A simple experiment you can try involves folding a sheet of paper into different cross-sections, like a tube or a corrugated shape, and then adding small weights. You will notice that the triangular or corrugated section holds much more. This is why cardboard has a fluted middle layer. In Year 7, you will test simple model bridges and learn why triangles are the strongest shape for frameworks (trusses).
你可以尝试一个简单的实验：将一张纸折叠成不同的截面形状，比如圆管形或瓦楞形，然后放上小重物。你会发现三角形或瓦楞截面的承重能力要强得多。这就是为什么卡纸板中间有一层瓦楞层。在七年级，你将测试简单的桥梁模型，并了解为什么三角形是桁架结构中最坚固的形状。
Moment of force = Force × Perpendicular distance from pivot (M = F × d)
力矩 = 力 × 到支点的垂直距离 (M = F × d)
7. Mechanisms and Simple Machines | 机械构造与简单机械
Mechanisms convert one type of motion or force into another. Levers, pulleys, gears, and linkages are all simple machines that make work easier. A first-class lever has the pivot between the effort and load, like a seesaw. With gears, a small driver gear turning a larger follower gear reduces speed but increases torque (rotational force). The gear ratio tells you how much the speed changes.
机械构造能将一种运动或力转换为另一种。杠杆、滑轮、齿轮和连杆都是使工作更轻松的简单机械。一类杠杆的支点在施力点与负载之间，就像跷跷板。使用齿轮时，小主动齿轮带动大从动齿轮会降低速度，但增加扭矩（旋转力）。齿轮比能告诉你速度变化了多少。
Building a cardboard scissor lift or a simple pulley system is a great way to understand mechanical advantage. Mechanical advantage is the ratio load/effort. If a pulley system lets you lift 40 N with only 10 N of effort, the mechanical advantage is 4. In the workshop, you will make models that drive wheels with rubber bands or motors, observing how motion transfers through shafts and bearings.
制作一个卡纸剪式升降台或一个简单的滑轮系统，是理解机械效益的好方法。机械效益是负载与施力的比值。如果一个滑轮系统让你只用10 N的力就能举起40 N的重物，那么机械效益就是4。在工作坊中，你将用橡皮筋或马达驱动轮子制作模型，观察运动如何通过轴和轴承传递。
8. Introduction to Electronics | 电子学入门
Electronic circuits control many modern devices. A basic circuit contains a power source (like a battery), a load (such as an LED), and conductors (wires). You will learn to draw circuit diagrams using standard symbols. Switches can turn current on and off, while components like resistors limit current flow. Ohm’s law links voltage (V), current (I), and resistance (R):
电子电路控制着许多现代设备。一个基本电路包含电源（如电池）、负载（如LED）和导体（导线）。你将学习使用标准符号绘制电路图。开关可以接通和断开电流，而电阻等元件则会限制电流的流动。欧姆定律关联了电压（V）、电流（I）和电阻（R）：
V = I × R
电压 = 电流 × 电阻
A common starting project is building a simple series circuit on a breadboard. You can make an LED light up by connecting it through a current-limiting resistor to a 9 V battery. Later, you might add a light-dependent resistor (LDR) and a transistor to create a nightlight that switches on when it gets dark. Measuring with a multimeter will be an essential skill: voltage in volts, current in amperes, resistance in ohms.
一个常见的入门项目是在面包板上搭建一个简单的串联电路。你可以将LED通过一个限流电阻连接到9 V电池上，使其亮起。之后，你可能会添加一个光敏电阻（LDR）和一个晶体管，制作一个当天黑时自动打开的小夜灯。使用万用表进行测量将是一项基本技能：电压的单位是伏特，电流是安培，电阻是欧姆。
9. Programming for Engineering | 工程编程基础
Many engineering devices now include microcontrollers—tiny computers that control motors, sensors, and displays. In Year 7, you might program a BBC micro:bit or an Arduino. You will learn to write simple code using block-based editors (like MakeCode) that let you snap blocks together. This way, you can make LEDs flash, detect button presses, and read temperature sensors.
如今，许多工程设备都包含微控制器——那些控制电机、传感器和显示屏的微型计算机。在七年级，你可能会为BBC micro:bit或Arduino编程。你将学习使用积木式编辑器（如MakeCode）编写简单代码，将积木块拼接在一起。这样，你就能让LED闪烁、检测按钮按下和读取温度传感器。
Programming teaches logical thinking. You will use loops to repeat actions, if-else statements to make decisions, and variables to store data. For example, you could write a program that measures tilt and controls a rover’s wheels. Understanding that a machine follows exactly what you code reinforces the importance of precision. Even small mistakes can cause a robot to go the wrong way.
编程能培养逻辑思维。你将使用循环来重复动作，使用if-else语句来做决策，以及使用变量来存储数据。例如，你可以编写一个测量倾斜度并控制探测车车轮的程序。明白机器会准确执行你所编写的代码，这强调了精确性的重要。即使是很小的错误也可能导致机器人朝错误的方向行进。
10. Sustainability and The Environment | 可持续性与环境
Engineers play a vital role in protecting the planet. The 6Rs of sustainability—Rethink, Refuse, Reduce, Reuse, Recycle, and Repair—guide cleaner design. When you design a product, you should think about where materials come from, how much energy is used in manufacture, and what happens at the end of its life. Using renewable materials and designing for easy disassembly lowers environmental impact.
工程师在保护地球方面发挥着至关重要的作用。可持续性的6R原则——重新思考、拒绝、减少、重复使用、回收和修复——指导着更清洁的设计。当你设计产品时，应该考虑材料的来源、制造过程中消耗了多少能源，以及产品寿命结束后会发生什么。使用可再生材料并设计易于拆卸的结构，可以降低对环境的影响。
In Year 7 projects, you will be encouraged to reuse scrap materials from other classes. You might design a wind-powered vehicle or a solar oven from recycled foil and cardboard. Understanding life cycle assessment (LCA) helps engineers compare the total eco-footprint of different solutions. Even a simple choice like using a USB-rechargeable cell instead of disposable batteries makes a difference.
在七年级的项目中，你会被鼓励重复使用其他课堂留下的废料。你可能会用回收的铝箔和卡纸设计一辆风力驱动车或一个太阳能烤炉。理解生命周期评估（LCA）有助于工程师比较不同解决方案的总体生态足迹。即便是像使用USB充电电池而非一次性电池这样简单的选择，也能带来改变。
11. Drawing and Communication Skills | 绘图与沟通技巧
Engineers need to communicate ideas clearly. Technical drawing is the universal language of engineering. You will learn to sketch in 2D and 3D using freehand techniques, starting with isometric grids and orthographic projection. Dimensions must be shown clearly with arrows, extension lines, and accurate measurements. A well-labelled sketch can explain an idea faster than a thousand words.
工程师需要清晰地交流想法。技术绘图是工程的通用语言。你将学习使用徒手技巧绘制二维和三维草图，从等轴测网格纸和正投影图开始。必须用箭头、延伸线和精确的测量值清楚地标注尺寸。一张标注清晰的草图能比千言万语更快地解释一个想法。
Beyond drawing, you will practice presenting your design ideas verbally and in writing. You might keep an engineering notebook where you glue in sketches, notes, and photographs of your models. Evaluating your own work and giving constructive feedback to classmates builds teamwork skills. Engineers never work in isolation; they collaborate with designers, scientists, and customers.
除了绘图，你还将练习以口头和书面形式展示设计想法。你可以保持一本工程笔记本，里面贴上草图、笔记和模型照片。评价自己的作品并给同学建设性的反馈，能培养团队合作技能。工程师从不孤立工作；他们与设计师、科学家和客户合作。
12. Getting Ready for Year 7 Engineering | 为七年级工程课做好准备
As you prepare for September, gather a few simple items: a sketchbook, a pencil, a ruler, and a curiosity about how things work. Watch bridges and cranes when you travel; notice the materials in your kitchen or park. Try taking apart an old, broken toy to see the gears, switches, and motors inside (always with an adult’s supervision). Every observation is a mini engineering lesson.
当你为九月做准备时，可以收集几样简单的物品：一个素描本、一支铅笔、一把尺子，以及对事物运作方式的好奇心。出行时观察桥梁和起重机；留意你厨房或公园里的材料。尝试拆解一个旧的、坏掉的玩具，看看里面的齿轮、开关和马达（一定要有成人在旁监护）。每一次观察都是一堂微型工程课。
