1. What is Engineering? | 什么是工程？
Engineering is the process of designing, building, and testing solutions to real-world problems. Engineers use science and maths to create things that make our lives better—from bridges and cars to smartphones and medical devices. It’s not just about fixing things; it’s about imagining something that doesn’t exist yet and making it real.
工程是设计、构建和测试现实问题解决方案的过程。工程师利用科学和数学创造让生活更美好的事物——从桥梁和汽车到智能手机和医疗设备。它不仅仅是修理东西，更是想象出尚未存在的事物并使其变为现实。
In Year 7, you will start to think like an engineer. You will learn to ask questions such as ‘What problem am I solving?’ and ‘Who is this solution for?’ This way of thinking is called the engineering mind-set, and it is the first step in every project you will undertake.
在 Year 7，你将开始像工程师一样思考。你将学会提出诸如“我正在解决什么问题？”和“这个解决方案是为谁设计的？”这类问题。这种思维方式被称为工程思维，它是你未来每个项目的第一步。
2. The Engineering Design Process | 工程设计过程
Engineers follow a structured method to turn ideas into reality. This is often called the design process. The core stages are: Identify the need, research, brainstorm ideas, select the best solution, build a prototype, test and evaluate, and then improve. This cycle can repeat many times until the product meets the requirements.
工程师遵循一种有序的方法将想法变为现实，这通常被称为设计过程。核心阶段是：明确需求、调研、头脑风暴、选择最佳方案、建造原型、测试与评估，然后进行改进。这个循环可以重复多次，直到产品满足要求。
For example, if you are asked to design a pencil holder for your desk, you would first define what it must do (hold at least ten pencils), explore existing designs, sketch several ideas, choose one, make a model from cardboard, test it, and then refine the shape. Each step helps you learn and produce a better outcome.
例如，如果你被要求为书桌设计一个笔筒，你首先要定义它必须做什么（至少能放十支铅笔），研究已有的设计，绘制多个草图，选择一个，用硬纸板制作模型，测试它，然后改进形状。每一步都能帮助你学习并产生更好的成果。
3. Materials in Engineering | 工程材料
Choosing the right material is crucial in any engineering project. Common materials you will encounter in Year 7 include paper, card, wood, plastics, and metals. Each material has properties such as strength, hardness, flexibility, and density. Engineers select materials based on how well those properties match the function of the final product.
在任何工程项目中，选择合适的材料都至关重要。在 Year 7 你会接触到的常见材料包括纸张、卡纸、木材、塑料和金属。每种材料都有其特性，如强度、硬度、柔韧性和密度。工程师根据这些特性与最终产品功能的匹配程度来选择材料。
You will carry out simple tests to compare materials. For instance, you might hang weights from strips of different materials to see which one stretches least under load. You will learn to record your observations using terms like ‘brittle’, ‘ductile’, or ‘transparent’ and begin to link material properties to their everyday uses.
你将进行简单的测试来对比材料。例如，你可能会在不同的材料条上悬挂重物，看哪一种在负载下伸展最少。你还会学习使用诸如“脆性”、“延展性”或“透明”等术语记录观察结果，并开始将材料特性与它们的日常用途联系起来。
4. Forces and Structures | 力与结构
A structure is anything designed to support a load. In this topic you will study basic forces: tension (pulling), compression (pushing), bending, torsion (twisting), and shear. Understanding these forces helps engineers design bridges, towers, and even furniture that will not collapse.
结构是指任何设计用于支撑荷载的物体。在本主题中，你将学习基本的力：拉力（拉伸）、压力（压缩）、弯曲、扭转（扭曲）和剪切。理解这些力有助于工程师设计出不会倒塌的桥梁、塔楼甚至家具。
You will build simple frame structures from straws or lolly sticks and test them with small weights. You will see how adding triangles—called triangulation—makes a structure much stronger than a square. The key formula for a stationary object is that the sum of forces in any direction equals zero: ∑ F = 0. We will use this idea to explain why tall buildings stand up.
你将用吸管或冰棒棍搭建简单的框架结构，并用小砝码进行测试。你会看到加入三角形（称为三角加固）如何使结构比方形坚固得多。对于静止物体，关键公式是任何方向上力的总和为零：Fnet = 0。我们将用这一概念解释高楼大厦为何能屹立不倒。
5. Simple Machines | 简单机械
Simple machines make work easier by changing the direction or size of a force. The six classic simple machines are the lever, pulley, wheel and axle, inclined plane, wedge, and screw. You will focus on levers and pulleys in Year 7 because they clearly show the trade-off between force and distance.
简单机械通过改变力的方向或大小使工作更轻松。六种经典简单机械是杠杆、滑轮、轮轴、斜面、楔子和螺旋。Year 7 将重点学习杠杆和滑轮，因为它们清晰地展示了力与距离之间的权衡。
A lever has a fulcrum, an effort, and a load. The mechanical advantage (MA) is calculated as: MA = load ÷ effort. If you apply a small effort over a longer distance, you can lift a heavier load over a shorter distance. You will experiment with a ruler and a pencil as a fulcrum to feel how changing the pivot point affects the force needed.
杠杆有一个支点、一个施力点和一个负载。机械效益 (MA) 的计算公式为：MA = 负载 ÷ 施力。如果你在较长距离上施加较小的力，就可以在较短距离上提起较重的负载。你将用尺子和铅笔作为支点进行实验，感受改变支点位置如何影响所需力的大小。
6. Introduction to Electrical Circuits | 电路入门
Electricity is the flow of tiny particles called electrons around a complete loop. In your first electronics lessons, you will build simple circuits using a battery, wires, a switch, and a light bulb or motor. A circuit must be closed for current to flow; an open switch creates a break and stops the current.
电是被称为电子的微小粒子在一个完整回路中的流动。在你的第一堂电子课上，你将使用电池、导线、开关和小灯泡或马达搭建简单的电路。电路必须是闭合的才能让电流通过；打开的开关会造成断路，阻止电流通过。
You will be introduced to two types of circuit: series and parallel. In a series circuit, there is only one path for the current. If one bulb fails, all bulbs go out. In a parallel circuit, each bulb has its own path, so if one fails, the others remain on. The basic equation linking voltage, current, and resistance is Ohm’s Law: V = I × R. We will use this to understand why adding more bulbs in series makes them dimmer.
你将接触到两种电路：串联和并联。在串联电路中，电流只有一条路径。如果一只灯泡熄灭，所有灯泡都会熄灭。在并联电路中，每只灯泡有自己的路径，因此如果一只熄灭，其他灯泡仍然亮着。连接电压、电流和电阻的基本方程为欧姆定律：V = I × R。我们将用它来解释为何串联更多灯泡会使它们变暗。
7. Digital Control and Programming | 数字控制与编程
Modern engineering often involves programming microcontrollers to automate tasks. In Year 7, you might use a platform like BBC micro:bit or Arduino to write simple programs. You will learn sequencing, loops, and conditional statements, which are the building blocks of code.
现代工程经常涉及对微控制器编程以实现自动化任务。在 Year 7，你可能会使用类似 BBC micro:bit 或 Arduino 的平台编写简单程序。你将学习顺序、循环和条件语句，这些都是代码的构建模块。
For example, you will program an LED to flash on and off. The code might say: repeat forever { turn LED on, wait 500 milliseconds, turn LED off, wait 500 milliseconds }. You will also connect sensors, such as a light sensor or a button, and write code that responds ‘If the button is pressed, then sound the buzzer’. This connects physical hardware with logical thinking.
例如，你将编写程序让 LED 闪烁。代码可能是：无限循环 { 点亮 LED，等待 500 毫秒，熄灭 LED，等待 500 毫秒 }。你还会连接传感器，如光线传感器或按钮，并编写响应代码：“如果按钮被按下，则鸣响蜂鸣器”。这将物理硬件与逻辑思维联系起来。
8. Computer-Aided Design | 计算机辅助设计
Engineers often create digital models of their ideas before building them. You will use introductory CAD software, such as Tinkercad or 2D Design, to draw shapes and assemble virtual prototypes. CAD allows you to view your design from different angles and check dimensions precisely.
工程师在真正制造前通常会先创建其创意的数字模型。你将使用入门级 CAD 软件，例如 Tinkercad 或 2D Design，来绘制形状并组装虚拟原型。CAD 允许你从不同角度查看设计并精确检查尺寸。
In your first project, you may draw a simple key ring and then 3D-print it. You will learn basic commands: create a circle, extrude it to add thickness, and add a hole for a ring. Understanding co-ordinate systems (X, Y, Z axes) is essential, as every point on your model has a set of numbers defining its position.
在你的第一个项目中，你可能会画一个简单的钥匙圈然后将其 3D 打印出来。你将学习基本命令：创建一个圆，将其拉伸以增加厚度，并添加一个用于系环的孔。理解坐标系（X, Y, Z 轴）至关重要，因为模型上的每个点都有一组数字定义其位置。
9. Environmental Sustainability | 环境可持续性
Engineers today must consider the environmental impact of their designs. This means choosing materials that can be recycled, designing products that use less energy, and finding ways to reduce waste. The concept of the ‘6 Rs’—Rethink, Refuse, Reduce, Reuse, Recycle, Repair—provides a framework for sustainable thinking.
当今的工程师必须考虑其设计对环境的影响。这意味着选择可回收材料、设计节能产品，并寻求减少浪费的方法。“6R”概念——重新思考、拒绝、减少、再利用、回收、修复——为可持续思维提供了一个框架。
During your practical work, you will be encouraged to repurpose scrap materials instead of always using new ones. When evaluating a finished product, you will discuss its entire life cycle: from extracting raw materials, to manufacturing, to eventual disposal. Even small changes, like designing a product that uses fewer plastic parts, can make a big difference.
在你的实践作业中，你会被鼓励重复利用废弃材料，而非总是使用新材料。在评估一个成品时，你将讨论其整个生命周期：从提取原材料，到制造，再到最终处置。即使微小的改变，如设计一个使用更少塑料部件的产品，也能带来很大不同。
10. Teamwork in Engineering | 工程团队合作
Rarely does an engineer work alone. Large projects require teams of specialists—mechanical, electrical, civil, and software engineers—all working together. In your classroom, you will practise teamwork by taking on roles such as designer, builder, tester, and project manager in group activities.
工程师很少独自工作。大型项目需要专家团队——机械、电气、土建和软件工程师——共同协作。在你的课堂上，你将通过在小组活动中承担设计师、建造者、测试员和项目经理等角色来练习团队合作。
Effective teamwork depends on clear communication. You will learn to share your ideas through annotated sketches and verbal explanations, and to give constructive feedback to others. Listening to different perspectives often leads to a much better final design. You will also discover that failing together is a powerful way to learn, as long as you identify what went wrong and try again.
有效的团队合作依赖于清晰的沟通。你将学习通过注释草图和口头说明分享想法，并向他人提供建设性反馈。倾听不同观点常常会带来更好的最终设计。你还会发现，只要找出问题所在并再次尝试，一起失败也是一种强大的学习方式。
11. Engineering and Everyday Life | 工程与日常生活
Engineering touches almost every part of your daily routine. The water you drink flows through engineered pipes and filtration systems. The smartphone in your pocket contains thousands of engineered components, from microchips to the glass screen. Even the chair you are sitting on was designed to be comfortable, stable, and cost-effective to manufacture.
工程关乎你日常生活的几乎每一个部分。你喝的水流经设计精良的管道和过滤系统。口袋里的智能手机包含从微芯片到玻璃屏幕的数千个工程部件。甚至你正坐着的椅子也是经过设计，以达到舒适、稳固且制造成本合理的目的。
By becoming more observant, you can start to see the engineering behind ordinary objects. Ask yourself: Why is a bicycle frame made from hollow tubes? How does a zip work? What makes a bridge wobble in the wind? These questions spark curiosity, which is the fuel for every great engineer. Keep a small notebook to record your engineering questions over the summer.
通过更加留心观察，你就能开始看到普通物品背后的工程原理。问问自己：为什么自行车车架由空心管制成？拉链是如何工作的？是什么让桥在风中晃动？这些问题会激发好奇心，而好奇心正是每位杰出工程师的动力源泉。在暑期准备一个小笔记本，记录下你的工程问题。
12. Preparing for Year 7 Engineering | 为 Year 7 工程课做准备
As you move towards the start of the school year, there are easy ways to keep your engineering brain active. Try building a tower from uncooked spaghetti and marshmallows; time how long a paper helicopter stays in the air after changing its blade shape; or take apart an old, broken toy to see what’s inside. These hands-on mini-challenges will sharpen your problem-solving skills.
随着新学年的临近，有很多简单的方法可以让你保持工程思维的活跃。尝试用未煮过的意大利面和棉花糖搭建一座塔；计时改变桨叶形状后纸直升机的滞空时间；或者拆解一个旧的坏玩具，看看里面是什么。这些动手小挑战将磨练你解决问题的能力。
Also, look over the CCEA Year 7 curriculum expectations. Familiarise yourself with key vocabulary such as ‘specification’, ‘prototype’, ‘aesthetics’, and ‘mechanism’. You don’t need to memorise them, but hearing them in advance will make your first lessons feel like a review rather than something brand new. Most importantly, stay curious and remember that every expert engineer once started exactly where you are now.
此外，请浏览 CCEA Year 7 的课程期望。熟悉一些关键术语，如“规格说明”、“原型”、“美学”和“机械装置”。你不必记住它们，但提前接触到这些词汇会让你的第一堂课更像是复习而非全新的内容。最重要的是，保持好奇心，并记住每位专业工程师都曾站在与你完全相同的起点上。
