📚 Year 7 CIE Engineering: Summer Preparation and Bridging Course | Year 7 CIE 工程：暑期预习与衔接课程
Starting secondary school brings exciting new subjects, and for many students following the Cambridge pathway, Year 7 Engineering is a hands-on introduction to designing, making and problem-solving. This bridging guide will help you prepare over the summer, building confidence before your first lesson.
升入中学带来了令人兴奋的新学科，对于许多遵循剑桥课程路径的学生来说，Year 7 工程是一门通过动手操作来介绍设计、制作和解决问题的入门课程。这份衔接指南将帮助你在暑期做好准备，在第一堂课之前建立信心。
1. Understanding the Year 7 Engineering Curriculum | 了解 Year 7 工程课程
Year 7 Engineering typically covers a broad range of foundational topics, including workshop safety, material properties, simple mechanisms, basic electronics, and the design process.
Year 7 工程通常涵盖广泛的基础主题，包括车间安全、材料性质、简单机械、基础电子学和设计流程。
Your school may follow the Cambridge Lower Secondary framework or a bespoke programme, but the core aim is to develop practical skills and creative thinking.
你的学校可能遵循剑桥初中框架或定制课程，但其核心目标是培养实践技能和创造性思维。
2. Why Summer Preparation Matters | 为什么暑期预习很重要
Engineering involves both theory and hands-on work. Arriving with some background knowledge reduces first-term anxiety and helps you engage more actively in projects.
工程学既涉及理论又涉及动手操作。带着一些背景知识入学可以减少第一学期的焦虑，并帮助你更积极地参与项目。
Familiarising yourself with key terms and basic tools now means you can focus on skill building when school starts.
现在熟悉关键术语和基本工具，意味着开学后你可以专注于技能培养。
3. Health and Safety First | 健康与安全第一
Safety is the most important rule in any engineering workshop. You must learn to identify hazards, wear appropriate protective equipment (PPE), and follow instructions carefully.
在任何工程车间里，安全都是最重要的准则。你必须学会识别危险，穿戴适当的个人防护装备（PPE），并认真遵循指令。
Common PPE includes safety goggles, aprons, and sturdy shoes. Never operate machinery without supervision.
常见的个人防护装备包括护目镜、围裙和结实的鞋子。切勿在无人监督的情况下操作机器。
Keep the workshop tidy and always return tools to their correct places. A clean workspace prevents accidents.
保持车间整洁，并始终将工具放回正确的位置。干净的工作区域可以防止事故。
- Wear safety goggles at all times.
- 始终佩戴护目镜。
- Tie back long hair and remove loose jewellery.
- 将长发扎起并取下松散的饰品。
- Report any accidents immediately.
- 发生任何事故立即报告。
4. Getting to Know Tools and Equipment | 认识工具和设备
You will use tools such as hacksaws, files, screwdrivers, and soldering irons. Understanding their names and proper use is essential before practical lessons.
你将使用钢锯、锉刀、螺丝刀和电烙铁等工具。在实践课前了解它们的名称和正确用法至关重要。
Start by looking at pictures or videos of a typical school workshop and learn the difference between hand tools and power tools.
可以从查看典型学校车间的图片或视频开始，了解手动工具和电动工具的区别。
Hand tools are powered by your own force, while power tools use electricity or batteries. Both require care and respect.
手动工具由你自身的力驱动，而电动工具则使用电力或电池。两者都需要小心和尊重。
5. Exploring Materials and Their Properties | 探索材料及其性质
Engineers choose materials based on properties such as strength, flexibility, conductivity, and weight. Common materials in Year 7 include wood, metal, plastic, and cardboard.
工程师根据强度、柔韧性、导电性和重量等性质来选择材料。Year 7 中常见的材料包括木材、金属、塑料和纸板。
Try to compare a metal spoon and a plastic spoon – which conducts heat better? Such simple observations build material knowledge.
试着比较金属勺子和塑料勺子——哪个导热更好？这种简单的观察可以积累材料知识。
| Property (性质) | Example in Engineering (工程实例) |
|---|---|
| Strength / 强度 | Steel used in bridges / 桥梁用钢 |
| Malleability / 延展性 | Aluminium foil / 铝箔 |
| Electrical conductivity / 导电性 | Copper wires / 铜导线 |
| Thermal insulation / 隔热性 | Polystyrene cups / 聚苯乙烯杯 |
6. The Design Process in Engineering | 工程设计流程
Every engineering project follows a design process: identify a problem, research, generate ideas, develop a solution, make a prototype, test and evaluate.
每个工程项目都遵循一个设计流程：确定问题、研究、生成创意、开发解决方案、制作原型、测试和评估。
You can practise this cycle at home by designing a simple object like a pencil holder. Sketch your ideas, list materials, and think about improvements.
你可以在家设计一个简单的物品（如笔筒）来练习这个循环。画出你的创意草图，列出材料，并思考改进方案。
- Identify the problem or need.
- 确定问题或需求。
- Research existing solutions.
- 研究现有解决方案。

7. Simple Mechanisms: Levers, Pulleys and Gears | 简单机械：杠杆、滑轮和齿轮
A mechanism changes input motion and force into a desired output. Levers, pulleys, and gears are fundamental examples you will explore.
机械装置将输入的运动和力转变为期望的输出。杠杆、滑轮和齿轮是你将探索的基本例子。
You can experiment with a seesaw to understand how a lever works: when the pivot is in the middle, equal weights balance.
你可以用跷跷板做实验来理解杠杆的工作原理：当支点在中间时，相等的重量会保持平衡。
The relationship between load and effort is described by mechanical advantage.
负载与作用力之间的关系用机械效益来描述。
Mechanical Advantage = Load ÷ Effort
机械效益 = 负载 ÷ 作用力
Gears are wheels with teeth that mesh together to transmit rotary motion. A large gear driving a small gear increases speed but reduces torque.
齿轮是带有齿的轮子，它们啮合在一起以传递旋转运动。大齿轮驱动小齿轮会提高转速，但会降低扭矩。
8. Basic Electronics: Circuits and Components | 基础电子学：电路和元器件
You will learn about simple circuits, batteries, switches, bulbs, and buzzers. Understanding how electricity flows in a loop is the foundation.
你将学习简单的电路、电池、开关、灯泡和蜂鸣器。理解电流如何在回路中流动是基础。

Ohm’s Law, which you might encounter later, states:
你以后可能会遇到的欧姆定律指出：
Voltage = Current × Resistance (V = I × R)
电压 = 电流 × 电阻 (V = I × R)
Draw simple circuit diagrams using standard symbols for cells, lamps, and switches. Practising now will make your first electronics lesson much easier.
使用标准的电池、灯泡和开关符号绘制简单的电路图。现在练习会使你的第一节电子学课程轻松很多。

You might use formulas like:
你可能会用到以下公式：
Area of a rectangle = length × width
长方形的面积 = 长 × 宽
Gear Ratio = Number of Teeth on Driven Gear ÷ Number of Teeth on Driver Gear
传动比 = 从动齿轮齿数 ÷ 主动齿轮齿数
Understanding units like millimetres (mm), centimetres (cm) and metres (m) is crucial. Practise converting between them and measuring objects around your home.
