2. The Engineering Design Cycle | 工程设计循环
Central to the Cambridge engineering syllabus is the design cycle, a systematic approach to problem-solving. Students begin by identifying a need or problem through research and questioning. They learn to write a clear design brief that outlines the purpose, target user, and key constraints for their project.
剑桥工程大纲的核心是设计循环，一种系统化解决问题的方法。学生首先通过研究和提问来识别需求或问题。他们学习撰写清晰的设计简报，概述项目的目的、目标用户和关键限制条件。
Next, learners generate a range of possible solutions using techniques such as brainstorming, sketching, and simple modelling. They then select the most promising idea and develop it in detail, often creating prototypes from card, foam, or 3D-printed parts. Testing and evaluation follow, where students gather feedback and measure performance against the original specifications. Finally, they refine their designs, completing the iterative loop.
接下来，学习者使用头脑风暴、草图绘制和简单建模等技术生成一系列可能的解决方案。然后选择最有希望的想法并进行详细开发，通常使用卡纸、泡沫或 3D 打印部件制作原型。随后进行测试和评估，学生收集反馈并根据原始规格测量性能。最后，他们改进设计，完成迭代循环。
3. Materials and Their Properties | 材料及其性能
Understanding the characteristics of engineering materials is vital for making informed design choices. Year 8 students investigate metals, polymers, woods, and composites, learning to distinguish between them based on properties such as strength, hardness, ductility, density, and thermal conductivity. They also explore how the internal structure of a material affects its macroscopic behaviour.
理解工程材料的特性对于做出明智的设计选择至关重要。Year 8 学生研究金属、聚合物、木材和复合材料，学习根据强度、硬度、延展性、密度和导热性等属性区分它们。他们还探索材料的内部结构如何影响其宏观行为。
Practical experiments might involve testing samples under tension, measuring electrical conductivity, or observing corrosion. Students are introduced to concepts like elastic and plastic deformation, and they learn to justify material selection for specific applications, such as choosing a lightweight polymer for a drone frame or a corrosion-resistant metal for a bridge component.
实践实验可能包括测试样品在拉伸中的表现、测量导电性或观察腐蚀。学生引入了弹性和塑性变形的概念，并学习为特定应用论证材料选择，例如为无人机框架选择轻质聚合物，或为桥梁部件选择耐腐蚀金属。
4. Structural Mechanics | 结构力学
This topic introduces learners to the way forces act on structures and components. Key concepts include tension, compression, torsion, and shear. Students analyse simple beams, trusses, and frames to identify where these forces occur. They also calculate moments and equilibrium using basic equations.
本主题向学习者介绍力如何作用于结构和部件。关键概念包括拉伸、压缩、扭转和剪切。学生分析简单的梁、桁架和框架，以确定这些力出现的位置。他们还使用基本方程计算力矩和平衡。
Moment = Force x Perpendicular Distance (M = F x d)
力矩 = 力 x 垂直距离 (M = F x d)
Through activities like building spaghetti bridges or cardboard towers, students experience how shape and material distribution influence structural strength. They learn to reinforce structures using struts and ties, and they explore centre of gravity and stability, which are critical for designing anything from furniture to tall buildings.
通过建造意大利面桥梁或纸板塔等活动，学生体验形状和材料分布如何影响结构强度。他们学习使用支柱和拉杆加固结构，并探索重心和稳定性，这些对于设计从家具到高层建筑的任何东西都至关重要。
