📚 Parent’s Guide to Year 7 AQA Engineering | Year 7 AQA 工程：家长辅导指南

Engineering at Year 7 introduces your child to the creative and practical world of designing, making and problem-solving. Through the AQA-linked curriculum, students explore materials, structures, electronics and energy, while learning to use tools safely and think like an engineer. This guide is designed to help you support your child’s learning at home, even if you have no prior engineering background.

七年级工程学带领孩子进入一个充满创造力和实践的设计、制作与问题解决世界。在AQA相关课程中，学生探索材料、结构、电子和能源，同时学会安全使用工具并像工程师一样思考。本指南旨在帮助您在家支持孩子的学习，即使您没有任何工程经验。

1. What is Engineering? | 什么是工程？

Engineering is the application of science and maths to solve real-world problems. Engineers design bridges, cars, phones, medical devices and renewable energy systems. In Year 7, students begin to see how everyday objects are the result of careful planning, testing and refining.

工程学是应用科学和数学解决现实世界问题的学科。工程师设计桥梁、汽车、手机、医疗设备和可再生能源系统。在七年级，学生开始认识到日常物品都是精心规划、测试和改进的结果。

At this stage, the focus is on creativity combined with simple technical knowledge. Your child will be encouraged to ask ‘What is the problem?’, ‘Who is it for?’ and ‘How can it be made better?’. These are the foundations of the engineering design process.

在这个阶段，重点是创造力与简单技术知识的结合。鼓励孩子提问“问题是什么？”、“为谁设计？”以及“如何改进？”。这些是工程设计流程的基础。

2. The Design Process | 设计流程

The AQA approach in Year 7 follows a simplified design cycle: identify a need, research, generate ideas, develop a chosen idea, make a prototype, test and evaluate. Understanding this cycle helps your child structure their project work.

七年级AQA课程遵循简化的设计循环：确定需求、调研、产生创意、发展选定方案、制作原型、测试和评估。理解这一循环有助于孩子组织他们的项目作业。

You can support this at home by discussing everyday problems. For example, ask ‘How could we design a better lunchbox?’ and encourage sketches and notes. Even rough drawings help reinforce that engineering begins with clear thinking, not with perfect drawings.

您可以在家通过讨论日常问题来支持孩子。例如，问“我们如何设计一个更好的午餐盒？”并鼓励画草图和做笔记。即使是潦草的图画也能强化一个观念：工程始于清晰的思考，而非完美的绘图。

3. Health and Safety in the Workshop | 工作室的健康与安全

Safety is the first and most important lesson in any engineering workshop. Your child will learn to identify hazards, wear personal protective equipment (PPE) such as goggles and aprons, and follow rules like tying back long hair and never running.

在任何工程工作室里，安全都是第一课，也是最重要的一课。您的孩子将学会识别危险、穿戴护目镜和围裙等个人防护装备(PPE)，并遵守如束起长发、绝不在室内奔跑等规则。

Reinforce these habits at home whenever your child is using scissors, glue guns or simple tools. Ask them to explain the risks before starting a task. This builds a lifelong safety mindset and also boosts their confidence in the workshop.

当孩子在家使用剪刀、胶枪或简单工具时，请强化这些习惯。要求他们在开始一项任务前解释风险。这样做可培养终身安全意识，也能增加他们在工作室中的自信。

4. Materials and Their Properties | 材料及其特性

Year 7 students are introduced to common engineering materials: woods (pine, MDF), metals (aluminium, mild steel), plastics (acrylic, HDPE) and composites. They learn about properties such as hardness, toughness, flexibility and conductivity.

七年级学生会接触常见的工程材料：木材（松木、中密度纤维板）、金属（铝、低碳钢）、塑料（亚克力、高密度聚乙烯）和复合材料。他们学习硬度、韧性、柔韧性和导电性等特性。

Material	Key Property	工程材料	关键特性
Pine	Light, easy to cut	松木	轻质，易切割
Aluminium	Corrosion-resistant, lightweight	铝	耐腐蚀，轻量
Acrylic	Transparent, brittle	亚克力	透明，易碎

You do not need to buy special materials. Use household items such as cardboard, plastic bottles and aluminium foil to explore properties. Ask your child: ‘Which material would be best for a waterproof shelter, and why?’

您无需购买特殊材料。使用纸板、塑料瓶和铝箔等家用品来探索特性。问问孩子：“哪种材料最适合做防水庇护所？为什么？”

5. Measuring and Marking Out | 测量与划线

Accurate measuring is a core engineering skill. In Year 7, students learn to use a steel rule, try-square, scriber and tape measure. They practise reading millimetre markings and marking out straight lines and right angles on material.

精确测量是一项核心工程技能。在七年级，学生学习使用钢尺、直角尺、画针和卷尺。他们练习阅读毫米刻度，并在材料上划出直线和直角。

At home, ask your child to measure furniture or a bookshelf and mark where a new piece could fit. Encourage double-checking every measurement – the ‘measure twice, cut once’ principle – as mistakes at this stage are common but very educational.

在家可以让孩子测量家具或书架，并标出某个新配件可放置的位置。鼓励每次测量都复核——“量两次，切一次”原则——这个阶段的错误很常见，但极具教育意义。

6. Basic Hand Tools | 基本手工工具

Your child will become familiar with basic workshop tools: junior hacksaw, coping saw, bench hook, files, abrasive paper, hand drill and screwdrivers. They learn the correct grip and stance for each tool.

您的孩子将熟悉基本工作室工具：小手锯、线锯、工作台钩、锉刀、砂纸、手钻和螺丝刀。他们学习每种工具的正确握法和站姿。

At home, supervised tasks like sawing a wooden dowel or sanding a rough edge are excellent practice. Emphasise that patience and control are more important than speed. Always wear eye protection if using any striking or cutting tool.

在家进行监督下的操作，比如锯木销钉或打磨粗糙边缘，是很好的练习。强调耐心和控制比速度更重要。使用任何敲击或切割工具时，务必佩戴护目镜。

7. Joining Materials | 连接材料

Year 7 students explore different joining methods: PVA wood glue, hot melt glue, screws, nuts and bolts, and even simple slot-together joints. They discover that each joint has its own strength and weakness.

七年级学生探索不同的连接方法：白乳胶、热熔胶、螺丝、螺母和螺栓，甚至简单的槽接合。他们发现每种连接方式都有其优缺点。

You can extend this by comparing joints in household objects. Look at a chair – is it glued, screwed, or both? Ask your child to sketch how the load is transferred through the joint. This links directly to the forces topic.

您可以通过比较家居物品的连接方式来拓展知识。观察一把椅子——是胶合、螺丝固定，还是两者都用？让孩子画出载荷如何通过连接点传递。这直接与力的主题相关联。

8. Forces and Structures | 力与结构

Forces such as tension, compression, bending and torsion are introduced with simple diagrams and models. Students learn that triangles are the strongest shape for structural frames and that struts and ties behave differently.

拉力、压力、弯曲和扭转等力通过简单图示和模型引入。学生学习三角形是结构框架最稳定的形状，支柱与拉杆的受力表现不同。

Force = Mass x Acceleration (F = m x a)

力 = 质量 × 加速度 (F = m × a)

Try building spaghetti and marshmallow structures at home. Ask: ‘Where is the compression? Where is the tension?’ This hands-on challenge is fun and reinforces engineering concepts without any special equipment.

在家试试用意面和棉花糖搭建结构。问问：“哪里承受压力？哪里承受拉力？”这个动手挑战既有趣，又无需特殊设备，能巩固工程概念。

9. Simple Electronics | 简单电子学

Basic circuits form part of the Year 7 engineering introduction. Your child will build series circuits with batteries, switches, LEDs and buzzers. They learn the symbols for components and the concept of current flow.

基本电路是七年级工程学入门的一部分。您的孩子将用电池、开关、LED和蜂鸣器搭建串联电路。他们学习元器件符号和电流的概念。

Ohm’s Law is often mentioned at this level in its simplest form:

欧姆定律在这个阶段常以最简单的形式提及：

Voltage = Current x Resistance (V = I x R)

电压 = 电流 × 电阻 (V = I × R)

A simple electronics kit from a hobby shop can provide hours of safe, guided exploration. Always check that the voltage is low (e.g. 3 V to 6 V) and that circuits are disconnected before changing components.

一套来自兴趣商店的简单电子套件可以提供数小时安全、有指导的探索。务必确保电压较低（例如3V至6V），并在更换元器件前断开电路。

10. Renewable Energy | 可再生能源

Engineering is increasingly linked to sustainability. Year 7 students examine renewable energy sources: solar, wind, hydro and biomass. They consider how engineers design turbines, panels and systems to harness these resources efficiently.

工程学与可持续性越来越紧密地联系在一起。七年级学生考察可再生能源：太阳能、风能、水能和生物质能。他们思考工程师如何设计涡轮机、面板和系统以高效利用这些资源。

At home, you might watch a video of a wind farm or a hydroelectric dam. Discuss the advantages and disadvantages of each source. This connects engineering to global challenges like climate change and energy security.

在家可以观看风电场或水力发电大坝的视频。讨论每种能源的优缺点。这会将工程学与气候变化和能源安全等全球挑战联系起来。

11. Computer-Aided Design (CAD) | 计算机辅助设计

CAD is introduced at a basic level using free online tools like Tinkercad or 2D design software. Students create 3D models, resize shapes, and align parts. This develops spatial awareness and prepares them for more advanced design work.

通过使用Tinkercad等免费在线工具或二维设计软件，计算机辅助设计（CAD）在基础层面被引入。学生创建三维模型，调整形状大小并对齐零件。这培养了空间意识，为更高级的设计工作做准备。

Many schools set CAD homework. If your child struggles, sit with them and explore the program together. Clicking and dragging to build a simple keyring is a great starting project. Your encouragement in this digital skill is invaluable.

许多学校布置CAD作业。如果孩子遇到困难，可以和他们一起坐下来探索软件。用点击拖拽的方式做一个简单的钥匙扣就是很好的入门项目。您对这一数字技能的鼓励是无价的。

12. How Parents Can Help at Home | 家长如何在家辅导

Your role is not to be the expert, but to be a curious partner. Ask open-ended questions: ‘Why do you think that design worked?’ or ‘What would happen if we changed this shape?’ This prompts reflection, which is at the heart of engineering evaluation.

您的角色不是当专家，而是做一个充满好奇的伙伴。问开放式问题：“你认为那个设计为什么可行？”或“如果我们改变这个形状，会发生什么？”这会引发反思，而反思正是工程评估的核心。

Build a designated maker space – even a corner of a table – with basic materials, safe tools, and a place to store projects. Display finished models proudly. When children see that their work is valued, their motivation and confidence soar.

建立一个专属的动手制作空间——哪怕只是桌子一角——放上基本材料、安全工具和存放项目的地方。自豪地展示完成的模型。当孩子看到自己的作品受到重视时，他们的动力和信心会大增。

Finally, remind your child that failure is a normal part of engineering. A prototype that collapses or a circuit that doesn’t light up is not a mistake; it’s data. The best engineers iterate and improve. Celebrate ‘first attempts in learning’ together.

最后，提醒孩子失败是工程学习中的正常部分。倒塌的原型或不亮的电路不是错误，而是数据。最优秀的工程师会迭代和改进。一起庆祝“学习中的第一次尝试”。
