1. What is Engineering? An Introduction | 什么是工程？入门介绍
Engineering is the application of scientific and mathematical principles to design, build, and improve structures, machines, and systems. Engineers solve real-world problems by creating new technologies or improving existing ones. There are many branches of engineering, such as civil, mechanical, electrical, and software engineering. In your CCEA course, you will explore the role of engineering in everyday life, from the bridges we cross to the smartphones we use.
工程学是运用科学和数学原理来设计、建造和改良结构、机器与系统的一门学科。工程师通过创造新技术或改进现有技术来解决现实世界的问题。工程学有很多分支，如土木工程、机械工程、电气工程和软件工程。在 CCEA 课程中，你将探索工程在日常生活中的作用——从我们走过的桥梁到我们使用的智能手机。
As a Year 8 student, you don't need to know everything; you will start by understanding what engineers do and how they think. Think about your favourite invention and ask yourself: what problem does it solve? That is the engineer's mindset.
作为一名八年级学生，你不需要什么都知道；你将从了解工程师的工作和思维方式开始。想想你最喜欢的发明，问自己：它解决了什么问题？这就是工程师的思维方式。
2. The Engineering Design Process | 工程设计流程
The engineering design process is a step-by-step method used to solve problems. It typically includes: defining the problem, researching, brainstorming ideas, developing a solution, building a prototype, testing, evaluating, and improving. This cycle repeats until the best solution is found. In Year 8, you will learn to apply this process to simple projects, such as designing a bridge from spaghetti or a balloon-powered vehicle.
工程设计流程是用于解决问题的分步骤方法。它通常包括：界定问题、调查研究、头脑风暴、制定解决方案、制作原型、测试、评估和改进。这个循环会不断重复，直到找到最佳解决方案。在八年级，你将学习如何将这一流程应用于简单的项目，比如用意大利面条设计一座桥或制作气球动力小车。
Try a mini-challenge over the summer: design a paper tower that can hold a small book. Follow the steps – define the challenge, sketch at least three ideas, build one, test it, and then note what you would improve. This will get you ready for the practical activities you will do in class.
暑假里尝试一个小挑战：设计一个能支撑一本小书的纸塔。遵循各个步骤——确定挑战，画出至少三种构思草图，制作一个，进行测试，然后记录你会如何改进。这会让你为课堂上的实践活动做好准备。
3. Materials and Their Properties | 材料及其性能
Engineers choose materials based on their properties, such as strength, flexibility, conductivity, and cost. Common materials in school workshops include wood, metal, plastic, and composites. You need to understand the difference between natural and synthetic materials, and how properties like hardness or durability influence a design choice. The CCEA curriculum introduces you to basic material classification and testing.
工程师根据材料的性能来选择材料，例如强度、柔韧性、导电性和成本。学校车间里的常见材料包括木材、金属、塑料和复合材料。你需要了解天然材料与合成材料的区别，以及硬度、耐久性等特性如何影响设计选择。CCEA 课程会向你介绍基本的材料分类和测试。
A simple summer activity is to examine objects around your home and guess what materials they are made from and why. For example, why is a saucepan metal but its handle plastic? Make a table with three columns: object, material, and reason for choice. This will sharpen your observation skills.
一个简单的暑假活动是检查家中的物品，猜猜它们是用什么材料制成的，以及为什么。例如，为什么炖锅是金属的，而把手是塑料的？做一个三列表格：物品、材料、选择理由。这将提高你的观察能力。
| Object / 物品 | Material / 材料 | Reason / 理由 |
|---|---|---|
| Kitchen foil / 厨房铝箔 | Aluminium / 铝 | Light, malleable, good heat conductor / 轻、延展性好、导热好 |
| Window frame / 窗框 | uPVC or wood / uPVC 或木材 | Weather resistant, insulating / 耐候、隔热 |
4. Workshop Tools and Safe Working Practices | 车间工具与安全工作规范
Before you start making, you must learn about the tools you will use and how to work safely. In Year 8, you will be introduced to basic hand tools such as hacksaws, files, screwdrivers, hammers, and bench vices. You will learn their names, functions, and the correct way to hold and use them. Personal protective equipment (PPE) like safety goggles and aprons is essential, and you'll practise safe workshop behaviour at all times.
在开始动手制作之前，你必须了解将要使用的工具，以及如何安全地工作。在八年级，你将认识基本的手工工具，如钢锯、锉刀、螺丝刀、锤子和台虎钳。你会学习它们的名称、功能以及正确的握持和使用方法。护目镜和围裙等个人防护装备（PPE）必不可少，你将时刻练习安全的车间行为。
During the summer, you can prepare by creating a simple tool chart. Draw or find images of common workshop tools and write a sentence about what each is used for. Also, think about safety rules – list five “do’s” and five “don’ts” for a school workshop. This will make you feel more confident when you handle real tools.
暑假期间，你可以通过制作一个简单的工具图表来准备。画出或找到常见车间工具的图片，并为每种工具的用途写一句话。同时，思考安全规则——列出学校车间的五个“必须做”和五个“禁止做”。这会让你在真正使用工具时更有信心。
5. Simple Machines: Levers, Pulleys, and Gears | 简单机械：杠杆、滑轮和齿轮
Simple machines make work easier by changing the direction or magnitude of a force. The three types you will study in Year 8 are levers, pulleys, and gears. A lever is a rigid bar that pivots around a fulcrum; examples include a seesaw or a crowbar. A pulley system uses a rope and wheel to lift loads, often reducing the effort needed. Gears transfer motion and force between rotating shafts, changing speed or torque. Understanding these principles is fundamental to mechanical engineering.
简单机械通过改变力的方向或大小使工作更轻松。你在八年级将要学习的三种类型是杠杆、滑轮和齿轮。杠杆是一根围绕支点转动的刚性杆；例子有跷跷板或撬棍。滑轮系统使用绳索和轮子来提升负载，通常能减少所需的力量。齿轮在旋转轴之间传递运动和力，改变速度或扭矩。理解这些原理是机械工程的基础。
You can explore simple machines at home. Try using a ruler and a pencil to lift a book – the pencil is the fulcrum and the ruler the lever. Experiment with different positions of the fulcrum to see how it changes the effort needed. You can also observe gears by looking at a bicycle's chain and sprockets. Draw diagrams to label the parts.
你可以在家探索简单机械。试着用一把尺子和一支铅笔来抬起一本书——铅笔是支点，尺子是杠杆。尝试不同的支点位置，看看它如何改变所需的力。你还可以通过观察自行车的链条和链轮来了解齿轮。画出简图并标注部件。
Mechanical advantage = Load ÷ Effort
机械效益 = 负载 ÷ 施力
6. Forces and Motion in Engineering | 工程中的力与运动
Forces are pushes or pulls that can cause objects to move, speed up, slow down, or change direction. In engineering, you need to consider forces such as tension, compression, shear, and torsion. Year 8 CCEA will introduce you to the ideas of balanced and unbalanced forces, and how structures can withstand different loads. Newton's laws of motion provide the scientific background, but you will first grasp these concepts through practical examples like bridges and towers.
力是推或拉，能够使物体移动、加速、减速或改变方向。在工程中，你需要考虑拉力、压力、剪切力和扭转力等。八年级 CCEA 课程将向你介绍平衡力与不平衡力的概念，以及结构如何承受不同的载荷。牛顿运动定律提供了科学背景，但你会先通过桥梁和塔架等实例来理解这些概念。
Build a simple structure from straws or rolled paper and test it by adding weights. Observe where it bends or breaks. This demonstrates how forces act on real objects. Make notes on the types of failure you see – was it buckling due to compression, or snapping under tension? This inquiry will feed directly into your school projects.
用吸管或卷纸建造一个简单的结构，然后通过增加重物来测试。观察它在何处弯折或断裂。这展示了力如何作用于真实物体。记录你看到的破坏类型——是因受压而弯曲，还是在受拉时断裂？这种探究将直接为你学校的项目提供养分。
7. Energy Sources and Applications | 能量来源与应用
All machines need energy to work. In engineering, we explore renewable and non-renewable energy sources, such as solar, wind, nuclear, and fossil fuels. You will learn how energy is converted from one form to another, for example, a wind turbine converting kinetic energy into electrical energy. A key concept is efficiency – how much of the input energy does useful work. Year 8 lessons will include simple energy transfers and the importance of sustainable design.
所有机器都需要能量才能工作。在工程中，我们探索可再生能源与不可再生能源，如太阳能、风能、核能和化石燃料。你将学习能量如何从一种形式转换为另一种形式，例如风力涡轮机将动能转化为电能。一个关键概念是效率——输入的能量有多少做了有用功。八年级的课程将包含简单的能量转移和可持续设计的重要性。
Create a list of five devices in your home and identify the energy change in each. For instance, a lamp converts electrical energy to light and heat. Then, research one renewable energy source and make a small poster explaining how it works and why it is good for the environment.
列出你家中的五个设备，并确定每个设备中的能量转换。例如，灯将电能转换为光能和热能。然后，研究一种可再生能源，并制作一份小海报，解释其工作原理及其对环境有益的原因。
8. Introduction to Technical Drawing | 技术制图入门
Technical drawing is the language of engineers. It allows you to communicate ideas clearly and accurately. In Year 8, you will learn basic drawing standards: using drawing boards, T-squares, and set squares to create neat 2-D orthographic projections. You will also practise dimensioning, line types (thick, thin, dashed), and simple isometric sketching. Third-angle projection is the convention used in the UK, and you will start to read and interpret simple engineering drawings.
技术制图是工程师的语言。它让你能够清晰准确地传达想法。在八年级，你将学习基本的绘图规范：使用绘图板、丁字尺和三角尺来绘制整洁的二维正交投影。你还将练习标注尺寸、线型（粗线、细线、虚线）以及简单的等距草图。英国使用的约定画法是第三角投影法，你将开始阅读和解读简单的工程图纸。
Over the summer, you can practise by drawing everyday objects such as a pencil sharpener or a toy block. Try to draw its front, top, and side views each in separate rectangles. Keep your lines straight and use a ruler. This is a great way to develop "engineer’s eyes". Label the views and add simple measurements.
暑假里，你可以通过绘制日常物品（如卷笔刀或积木）来练习。尝试分别在单独的长方形中绘制其前视图、俯视图和侧视图。保持线条笔直，并使用尺子。这是培养“工程师的眼睛”的好方法。标注视图，并添加简单的尺寸。
9. Measurement, Marking Out, and Precision | 测量、划线与精度
Accuracy is vital in engineering. You will learn to use instruments like steel rules, tape measures, callipers, and try squares to measure length, width, angle, and depth. Marking out is the process of transferring dimensions from a plan onto your material before cutting or shaping. Even a small mistake can ruin a project, so you will also learn to check your work and understand tolerances.
精度在工程中至关重要。你将学习使用钢尺、卷尺、卡尺和直角尺等工具来测量长度、宽度、角度和深度。划线就是在切割或塑形之前，将尺寸从图纸转移到材料上的过程。哪怕是一个小错误也可能毁掉一个项目，因此你还将学会检查工作并理解公差。
A great skill to practise at home is measuring with a ruler in millimetres. Pick ten objects and measure them, writing down the dimensions to the nearest millimetre. Then, try marking out a simple shape – a square or rectangle of given dimensions – on a piece of cardboard, and cut it out. Check how close your finished piece matches the intended size.
在家可以练习的一项很好的技能是用尺子以毫米为单位测量。挑选十件物品并测量它们，将尺寸精确到最接近的毫米记录下来。然后，尝试在一块硬纸板上划线标出一个简单的形状——一个给定尺寸的正方形或长方形——并将其剪下来。检查成品与预期尺寸的接近程度。
10. Problem Solving and Computational Thinking | 问题解决与计算思维
Engineering is fundamentally about solving problems. Computational thinking helps you break down complex problems into smaller, manageable parts (decomposition), recognise patterns, and develop step-by-step solutions (algorithms). In Year 8, you will encounter tasks that require logical reasoning, such as programming a simple robot or working out the sequence to assemble a product. These skills build a bridge to control technology and systems engineering.
工程学的本质在于解决问题。计算思维帮助你分解复杂问题为较小、可管理的部分（分解），识别模式，并制定分步解决方案（算法）。在八年级，你将遇到需要逻辑推理的任务，例如为简单的机器人编程，或确定组装产品的顺序。这些技能为控制技术和系统工程搭建了桥梁。
You can strengthen your problem-solving muscle by solving logic puzzles or learning the basics of block-based coding (like Scratch). Write pseudo-code for a daily task, such as making a sandwich, describing each step in simple commands. This is exactly the type of thinking you will apply when dealing with control systems later in the course.
你可以通过解逻辑谜题或学习基于模块的编程基础（如 Scratch）来增强解决问题的能力。为一项日常任务编写伪代码，比如制作三明治，用简单的指令描述每一步。这正是在课程后期处理控制系统时你会运用到的思维方式。
11. Teamwork and Communication in Projects | 项目中的团队合作与沟通
Most engineering projects are done in teams. You will work with classmates to brainstorm, delegate tasks, and combine different skills to build a final product. Effective communication is essential – sharing ideas clearly, listening to others, and giving constructive feedback. The CCEA course places strong emphasis on learners developing interpersonal skills alongside technical ability.
大多数工程项目都是团队完成的。你将与同学合作进行头脑风暴，分配任务，并结合不同的技能来打造最终产品。有效的沟通至关重要——清晰地分享想法、倾听他人、并提供建设性反馈。CCEA 课程非常重视学习者在培养技术能力的同时发展人际交往技能。
During the summer, you could join a club or start a small project with a friend or family member, such as building a model together. Pay attention to how you communicate and how you divide the work. Reflect on what went well and what could be improved in your teamwork. Write a short journal entry about the experience.
暑假期间，你可以加入一个俱乐部，或者与朋友或家人一起开展一个小项目，例如共同搭建一个模型。注意你们是如何沟通的，以及如何分工。反思团队合作中哪些方面做得好，哪些可以改进。针对这次经历写一篇简短的日记。
12. Preparing for Year 8: What to Expect | 为八年级做准备：预期内容
Year 8 Engineering under CCEA is an exciting blend of theory and practical work. You will spend time in the design studio and workshop, engaging in hands-on projects that could range from creating a simple mechatronic device to testing a structural frame. Assessment will be based on your design folios, practical outcomes, and your understanding of key concepts. The skills you practise over the summer – observation, measurement, drawing, and safe thinking – will give you a head start.
CCEA 八年级工程课程是理论与实践的精彩结合。你将在设计室和车间中花时间进行动手项目，这些项目的范围可能从制作简单的机电一体化装置到测试结构框架。评估将基于你的设计档案、实践成果以及对关键概念的理解。你在暑假中练习的技能——观察、测量、绘图和安全意识——将让你领先一步。
Enter the new school year with confidence. Keep a small sketchbook and note down any engineering ideas you come across, whether it's a clever hinge on a door or a news article about renewable energy. Curiosity is the engineer's superpower. We look forward to seeing what you design and build.
带着自信迎接新学年。准备一个小小的速写本，记录下你遇到的任何工程创意，无论是门上一个巧妙的合页，还是一篇关于可再生能源的新闻文章。好奇心是工程师的超能力。我们期待看到你设计和建造的成果。
