1. What is Engineering? | 什么是工程学？
Engineering is the application of science and mathematics to solve problems and create useful objects. Engineers design, build, test, and improve structures, machines, and systems. There are many branches, including mechanical, civil, electrical, and chemical engineering, but they all share a common goal: making life better, safer, and more efficient.
工程学是运用科学和数学知识来解决实际问题并创造有用物品的学科。工程师设计、建造、测试并改进结构、机器和系统。虽然工程学包含机械、土木、电气和化学等多个分支，但它们有着共同的目标：让生活更美好、更安全、更高效。
In Year 7, you will not specialise right away. Instead, you will explore the fundamental principles that underlie all types of engineering. You will learn how forces act on structures, how energy is converted, and how materials are chosen for specific tasks. Understanding what engineering truly means will help you see the world through a problem-solving lens.
在 Year 7 阶段，你并不会立即专攻某一方向，而是先探索所有工程类型背后的基本原理。你将学习力如何作用于结构、能量如何转换，以及如何为特定任务选择材料。真正理解工程学的含义，能让你用一种解决问题的眼光去观察周围的世界。
2. The SQA Engineering Learning Journey | SQA 工程学习之旅
The Scottish education system introduces engineering concepts early through subjects like science and technologies. In secondary school, the SQA offers a clear progression from Broad General Education in S1–S3 to National Qualifications in the senior phase. Year 7 (S1) marks the start of this journey, where you build a broad skill base in design, practical craftsmanship, and theoretical understanding.
苏格兰教育体系通过科学和技术等学科早早引入工程理念。在中学阶段，SQA 提供了一条清晰的进阶路径，从 S1 至 S3 的广泛通识教育，过渡到高年级的国家资格课程。Year 7（即 S1）标志着这一旅程的起点，你将在此阶段构建起设计、动手实践与理论理解方面的广泛技能基础。
By the end of S3, you will have the opportunity to choose engineering-related subjects such as Engineering Science, Graphic Communication, or Practical Woodworking. A solid start in Year 7 therefore makes later choices easier and more rewarding. The summer before Year 7 is the perfect time to ignite your curiosity and begin exploring engineering in a hands-on way.
到了 S3 结束时，你将有机会选择与工程相关的科目，例如工程科学、图形传播或实用木工。因此，在 Year 7 打好坚实基础会让后续的选择更加轻松和富有成效。Year 7 前的暑期正是点燃好奇心、开始动手探索工程的绝佳时机。
3. Why a Summer Bridging Course Matters | 暑期衔接课程的重要性
Moving from primary to secondary school brings new subjects, larger projects, and higher expectations. A bridging course helps close any gaps in scientific vocabulary, measurement skills, and logical thinking. It also reduces anxiety by making you familiar with the kind of activities you will encounter in your first engineering lessons.
从小学升入中学会带来新的科目、更大的项目和更高的要求。衔接课程有助于弥补在科学词汇、测量技能和逻辑思维方面的差距。同时，它还能让你提前熟悉在第一节工程课上会遇到的各种活动，从而减轻焦虑感。
Over the summer, you have time to work at your own pace without the pressure of deadlines. This means you can try out simple experiments, sketch ideas freely, and make mistakes without penalty. All of this builds a growth mindset, which is essential for engineering success.
暑假期间，你可以按自己的节奏学习，没有截止日期的压力。这意味着你可以自由尝试简单的实验、随心所欲地绘制设计草图，并在犯错时不受到惩罚。这一切都有助于培养成长型思维，这对工程学习的成功至关重要。
4. Key Mathematical Skills for Engineering | 工程必备的数学技能
Mathematics is the language of engineering. In Year 7, you will rely on basic arithmetic, fractions, decimals, and percentages to calculate lengths, areas, and material costs. You will also begin to use units of measurement such as millimetres (mm), centimetres (cm), and metres (m) with precision.
数学是工程学的语言。在 Year 7，你将依靠基础算术、分数、小数和百分数来计算长度、面积和材料成本，还会开始精确使用毫米（mm）、厘米（cm）和米（m）等计量单位。
Another key skill is reading and interpreting simple graphs. Engineers use graphs to understand how a material stretches or how a structure vibrates. Practise drawing bar charts and line graphs with clear labels and titles. This will prepare you for presenting your own investigation results later on.
另一项关键技能是阅读和解读简单图表。工程师借助图表来理解材料的拉伸情况或结构的振动方式。请练习绘制带有清晰标签和标题的柱状图与折线图，这将为你在日后呈现个人探究结果做好准备。
A useful formula to memorise is the area of a rectangle:
Area = length × width
一个值得记住的实用公式是矩形面积：
面积 = 长 × 宽
5. Fundamental Science Principles for Engineering | 工程基础科学原理
Engineers apply physics and chemistry to create safe and efficient designs. In Year 7, you will explore forces such as tension, compression, and shear. You will also investigate energy transfers, for example, how a battery powers a motor or how a spring stores energy.
工程师运用物理和化学知识来打造安全高效的设计。在 Year 7，你将探索拉力、压力和剪切力等力的类型，还会研究能量传递，例如电池如何驱动电机，或者弹簧如何储存能量。
Understanding the properties of materials is equally important. Why is a bridge made of steel and not plastic? What makes aluminium suitable for aircraft bodies? Simple at-home tests, such as bending paperclips or observing rust, can help you start thinking like a materials engineer.
理解材料特性同样重要。为什么桥梁用钢材而非塑料制造？是什么让铝合金适合做飞机外壳？简单的居家测试，比如弯折回形针或观察生锈过程，就能帮助你开始像材料工程师一样思考。
Remember the basic energy conversion:
Electrical energy → Kinetic energy + Thermal energy
记住这个基本的能量转换：
电能 → 动能 + 热能
6. Design Thinking and Problem Solving | 设计思维与问题解决
Engineering is not just about numbers; it is also a creative process. Design thinking involves understanding a problem, brainstorming ideas, building prototypes, and testing them. You will repeat this cycle many times, improving your solution with each iteration.
工程学不只有数字，它也是一个创造性的过程。设计思维包括理解问题、头脑风暴、制作原型并进行测试。你会多次重复这一循环，每次迭代都让解决方案更完善。
A simple exercise you can try is the ‘paper bridge challenge’. Using only three sheets of paper and some tape, build a bridge that spans a 20 cm gap and supports as many coins as possible. Document your failures and successes in a notebook to develop the habit of reflective practice.
你可以尝试一个简单的练习：“纸桥挑战”。仅用三张纸和一些胶带，搭建一座能跨越20厘米间隙并承载尽可能多硬币的桥梁。将你的失败与成功记录在笔记本中，以养成反思性实践的习惯。
7. Hands-On Projects for Beginners | 初学者动手项目
Nothing builds engineering confidence like getting your hands on real projects. Start with low-cost, low-risk activities such as constructing a marble run from cardboard tubes, assembling a simple LED circuit with a battery, or building a spaghetti tower that can hold a marshmallow.
没有什么比亲手完成真实项目更能建立工程自信了。从低成本、低风险的活动入手，比如用硬纸筒搭建弹珠轨道、用电池组装简单的 LED 电路，或者建造一座能承受棉花糖重量的意大利面塔。
For each project, write a short report: what you built, what worked, what broke, and how you would improve it next time. This mirrors the engineering design process and will impress your future teachers. Keep a portfolio of photographs and sketches to track your progress.
每个项目都请撰写一份简短报告：你建造了什么、哪些部分成功了、哪些失败了，以及下次将如何改进。这与工程设计流程完全一致，也会给你未来的老师留下深刻印象。用照片和草图建立作品集，记录自己的进步。
8. Getting to Know Engineering Tools and Materials | 认识工程工具与材料
In the school workshop, you will encounter tools such as saws, files, soldering irons, and measuring instruments. While you may not have access to all of these at home, you can familiarise yourself with their names, uses, and safety rules through online videos and illustrated guides.
在学校工坊中，你会接触到锯、锉、烙铁和测量工具等设备。虽然家中可能无法配备所有这些工具，但你可以通过在线视频和图文指南熟悉它们的名称、用途及安全规则。
Learn to identify common engineering materials: mild steel, aluminium, acrylic, plywood, and nylon. Understand why some are magnetic, some conduct electricity, and some are easy to shape. A simple material table can help you compare:
学会识别常见工程材料：低碳钢、铝、亚克力、胶合板和尼龙。理解为什么有些材料具有磁性，有些能导电，而有些则容易加工。一张简单的材料比较表能为你提供帮助：

|---|---|---|
| Mild steel / 低碳钢 | Strong, magnetic, rusts / 坚固、有磁性、会生锈 | Nuts and bolts / 螺母螺栓 |
| Aluminium / 铝 | Lightweight, non-magnetic, corrosion-resistant / 轻质、无磁性、耐腐蚀 | Drinks cans, aircraft / 饮料罐、飞机 |
| Acrylic / 亚克力 | Transparent, brittle, easy to cut / 透明、脆、易切割 | Displays, model making / 展示品、模型制作 |
9. Engineering Drawings and Sketches | 工程图纸与草图
Engineers communicate ideas through drawings. In Year 7, you will start with freehand sketches, then progress to isometric and orthographic projections. Freehand sketching helps you quickly express a design without needing rulers; accuracy comes later with technical drawing instruments.
工程师通过图纸交流想法。在 Year 7，你将先学习徒手草图，然后逐步进阶到等轴测图和正投影图。徒手草图能让你快速表达设计构思，无需使用尺规；精准度将在后续使用技术绘图工具时逐步培养。
Practise drawing simple objects like a pencil sharpener or a small box from three angles: front, top, and side. This is called third-angle projection. Add dimensions in millimetres and label each view. Keep your drawings neat and use a title block with your name, date, and project title.
练习从三个角度绘制简单物体，比如卷笔刀或小盒子：前视图、俯视图和侧视图。这被称为第三角投影。添加毫米单位的尺寸并标注每个视图。保持图纸整洁，并使用包含姓名、日期和项目名称的标题栏。
10. Safety First in Engineering | 工程安全第一
Safety rules protect you and others in any engineering environment. Always wear appropriate personal protective equipment (PPE), such as safety goggles, aprons, and closed-toe shoes. Tie back long hair, roll up sleeves, and never run in a workshop or laboratory.
在任何工程环境中，安全规则都能保护你和他人的安全。务必穿戴合适的个人防护装备（PPE），例如护目镜、防护围裙和包头鞋。束起长发、卷起衣袖，绝不在工坊或实验室内奔跑。
Remember the saying: ‘A tidy workspace is a safe workspace.’ Clean up spills immediately, return tools to their proper places, and report any damaged equipment to a teacher. By developing these habits early, you will be trusted to work on more complex projects as you progress.
请记住这句格言：“整洁的工作空间才是安全的工作空间。”立即清理洒溅的液体、将工具放回原位，并向老师报告任何损坏的设备。尽早养成这些习惯，你将获得信任，从而在进阶时能操作更复杂的项目。
11. Summer Reading and Resources | 暑期阅读与资源
