2. The Engineering Design Process | 工程设计流程
The engineering design process is a cyclical method used to develop products and systems. Students learn the key stages: defining the problem, researching, brainstorming solutions, developing a design proposal, building a prototype, testing and evaluating, and finally refining the design. This iterative approach mirrors professional practice and is applied throughout the year in small-scale projects.
工程设计流程是一种用于开发产品和系统的循环方法。学生们将学习关键阶段：定义问题、调研、头脑风暴解决方案、制定设计方案、制作原型、测试与评估，最后完善设计。这种迭代式方法反映了专业实践，并贯穿全年运用于小规模项目中。
Emphasis is placed on sketching, simple technical drawing, and using basic CAD (Computer-Aided Design) tools where available. Students document their process in an engineering logbook, which becomes a vital record of their thinking and decision-making.
重点放在草图绘制、简单技术制图，以及在可用条件下使用基础的CAD（计算机辅助设计）工具上。学生们在工程日志中记录他们的过程，这成为记录他们思考和决策的重要档案。
3. Materials and Their Properties | 材料及其性能
Understanding materials is fundamental to engineering. In Year 8, pupils classify materials into groups: metals, polymers, ceramics, composites, and smart materials. They investigate physical and mechanical properties such as hardness, toughness, ductility, conductivity, and density, and relate these properties to real-world applications.
理解材料是工程学的基础。在八年级，学生们将材料分类为：金属、聚合物、陶瓷、复合材料和智能材料。他们研究硬度和韧性、延展性、导电性和密度等物理及力学性能，并将这些性能与现实世界的应用联系起来。
- Metals: typically strong, ductile, and conductive (e.g., steel, aluminium).
- Polymers: lightweight, corrosion-resistant, easily moulded (e.g., PVC, nylon).
- Ceramics: hard, brittle, heat-resistant (e.g., glass, porcelain).
- Composites: combine properties of two or more materials (e.g., fibreglass, carbon fibre).
中文要点：
