该大纲旨在培养你发现问题、研究解决方案和清晰表达设计想法的能力。到学年结束时，你应该能够根据给定的任务简报，安全地使用车间实践方法制作一个简单的工程产品。
You will also learn to evaluate your own work and suggest improvements. This reflective process is a key skill that links directly to the iterative design approach used in higher-level OCR Engineering courses and real industry.
你还将学会评价自己的作品并提出改进建议。这一反思过程是一项关键技能，直接与高级 OCR 工程课程和真实行业中使用的迭代设计方法相衔接。
3. Key Topics: Engineering Drawing and Design | 重点主题：工程绘图与设计
You will start by learning how to read and produce simple engineering drawings. This includes isometric projection, where a 3D object is sketched on 2D paper using 30° angles, and orthographic views that show the front, side, and plan of a component.
你将从学习如何阅读和绘制简单的工程图样开始。这包括等轴测投影——在二维图纸上使用30°角绘制三维物体，以及展示零件前视图、侧视图和俯视图的正交视图。
Computer-aided design (CAD) is introduced at a basic level. You will use simple 2D design software to create precise outlines for laser cutting or vinyl cutting, understanding that digital models must be dimensioned accurately.
计算机辅助设计（CAD）以基础水平引入。你将使用简单的二维设计软件创建精确的轮廓，用于激光切割或乙烯基切割，并理解数字模型必须精确标注尺寸。
4. Key Topics: Materials and Their Properties | 重点主题：材料及其性能
Engineers must choose the right material for the job. In Year 7, you will investigate common workshop materials such as pine, medium-density fibreboard (MDF), acrylic, and aluminium. For each, you will test properties like hardness, flexibility, and thermal conductivity.
工程师必须为工作选择合适的材料。在7年级，你将研究常用车间材料，如松木、中密度纤维板（MDF）、亚克力和铝。对每种材料，你将测试硬度、柔韧性和导热性等性能。
The syllabus introduces the concepts of 'working properties' and 'physical properties'. You will learn, for example, that acrylic is thermoplastic, meaning it can be heated and reshaped, whereas MDF is a manufactured board that offers stability but can blunt tools quickly.
大纲引入了“加工性能”和“物理性能”的概念。例如，你将学习到亚克力是热塑性塑料，意味着它可以加热并重新塑形，而 MDF 是一种人造板，稳定性好但容易快速磨钝刀具。
5. Key Topics: Mechanisms and Forces | 重点主题：机构与力
You will explore simple mechanisms that change the direction, speed, or type of motion. Key systems include levers, pulleys, and gear trains. You may build a model with a crank and slider to convert rotary motion into linear motion.
你将探索改变运动方向、速度或类型的简单机构。关键系统包括杠杆、滑轮和齿轮系。你可能会制作一个带有曲柄和滑块机构的模型，将旋转运动转换为直线运动。
Basic force calculations are introduced using the equation:
基础力的计算使用以下公式引入：
Force = Mass × Acceleration (F = m × a)
You will apply this to determine the effort needed to lift a load with a lever, always using SI units (newtons for force, kilograms for mass).
你将应用这个公式来确定用杠杆举起重物所需的力，始终使用国际单位制（力的单位是牛顿，质量的单位是千克）。
6. Key Topics: Electronics and Control Systems | 重点主题：电子与控制系统
A short introductory module covers basic circuits. You will recognise common components such as resistors, light-emitting diodes (LEDs), and switches, and you will construct a simple series circuit on a breadboard.

你将体验一系列制作技术。手工具如开槽锯、锉刀和台钻用于加工木材和塑料。对于金属，你可能学习切割、钻孔以及使用去毛刺工具修整边缘。
The syllabus also covers scale of production. You will compare 'one-off' production, where a single unique item is made, with 'batch' production, where several identical items are created using a jig or a template. This helps you understand efficiency and consistency.
大纲还涵盖生产规模。你将比较“单件生产”——制造一个独特的物品，与“批量生产”——使用夹具或模板制作多个相同物品。这有助于你理解效率和一致性。
8. Key Topics: Health and Safety in the Workshop | 重点主题：车间健康与安全
Safety is the number one priority. Before entering the workshop, you must pass a safety induction that covers personal protective equipment (PPE) such as goggles, aprons, and dust masks. You will learn to identify hazard warning symbols and the location of emergency stops and fire extinguishers.
安全是第一要务。在进入车间之前，你必须通过安全入门培训，内容涵盖个人防护装备（PPE），如护目镜、围裙和防尘口罩。你将学习识别危险警告标志以及紧急停止按钮和灭火器的位置。
You will also be taught how to carry out a risk assessment for a simple task. This means identifying what could cause harm, who might be affected, and what control measures you will put in place. This skill is fundamental for all engineering qualifications.
你还将学习如何为一项简单任务进行风险评估。这意味着识别可能造成伤害的因素、可能受影响的人员以及你将采取的控制措施。这项技能是所有工程资格的基础。
9. Assessment Structure and Grading | 评估结构与分等级
Your overall grade is based on a combination of three components. Component 1 is a design portfolio, where you document the journey from initial sketch to final prototype. Component 2 is a practical making task, completed under timed conditions. Component 3 is a 45-minute written paper testing core principles.
你的总成绩基于三个部分的组合。第一部分是设计作品集，记录从最初草图到最终原型的全过程。第二部分是限时条件下完成的实践制作任务。第三部分是一份45分钟的笔试，考察核心原理。
The table below shows the approximate weighting of each component in the Year 7 assessment:
