1. Introduction to Engineering | 工程概论
Engineering is the creative application of science and mathematics to design, build, and improve structures, machines, and systems that meet human needs. At Year 7, students explore what engineers do across different fields, from civil and mechanical engineering to electrical and environmental engineering.
工程是将科学与数学创造性地应用于设计、建造和改进满足人类需求的结构、机器和系统。在七年级，学生将探索不同领域的工程师所做的工作，从土木工程、机械工程到电气工程和环境工程。
The course emphasises that engineering is not just about technical knowledge – it also requires curiosity, imagination, and the ability to work in teams. Students learn that failure is often a stepping stone to better design, encouraging a growth mindset from the very beginning.
本课程强调，工程不仅仅是技术知识——它还需要好奇心、想象力和团队合作的能力。学生将认识到，失败往往是通往更好设计的垫脚石，从一开始就鼓励他们培养成长型思维。
2. The Engineering Design Process | 工程设计流程
Central to the syllabus is the engineering design process, a structured cycle that helps students tackle problems systematically. The main stages include: identifying a need or problem, researching and brainstorming ideas, developing possible solutions, selecting the best one, building a prototype, testing and evaluating, and finally communicating the outcome.
课程的核心是工程设计流程，这是一个结构化的循环，帮助学生系统地解决问题。主要阶段包括：确定需求或问题、研究与头脑风暴、开发可能的解决方案、选择最佳方案、建造原型、测试与评估，最后进行成果交流。
Students learn to use simple design briefs and specifications. They are encouraged to sketch their ideas, annotate diagrams, and create simple models using everyday materials. This iterative process shows that design is rarely linear and that reflecting on each attempt leads to continuous improvement.
学生学习使用简单的设计纲要和规格说明。他们被鼓励绘制设计草图、注释图表，并使用日常材料制作简单模型。这个迭代过程表明，设计很少是线性的，每一次尝试后的反思都能带来持续改进。
3. Materials and Their Properties | 材料及其特性
Understanding materials is fundamental in engineering. Year 7 students investigate common engineering materials such as metals, plastics, wood, ceramics, and composites. They learn to classify materials based on properties like strength, hardness, flexibility, thermal conductivity, electrical conductivity, and density.
理解材料是工程学的基础。七年级学生将研究常见的工程材料，如金属、塑料、木材、陶瓷和复合材料。他们学会根据强度、硬度、柔韧性、导热性、导电性和密度等特性对材料进行分类。
Practical activities often involve testing materials under different conditions. For instance, students may compare the bending strength of wooden sticks, the weight-bearing capacity of different papers, or the insulating properties of various fabrics. The table below summarises some key material properties studied.
实践活动通常包括在不同条件下测试材料。例如，学生可以比较木棍的弯曲强度、不同纸张的承重能力或各种织物的绝缘性能。下面的表格总结了所学的一些关键材料特性。

Students also begin to consider sustainability, learning about renewable resources and the importance of recycling in engineering decisions.
学生也开始考虑可持续性，了解可再生资源以及循环利用在工程决策中的重要性。
4. Forces and Structures | 力与结构
This section introduces the concepts of forces, including push and pull, balanced and unbalanced forces, and how they act on structures. Students learn to measure force in newtons (N) using force meters and represent forces with simple arrow diagrams.
本节介绍力的概念，包括推力和拉力、平衡力与非平衡力，以及它们如何作用于结构。学生将学习使用测力计以牛顿 (N) 为单位测量力，并用简单的箭头图示表示力。
Key formula linking force, mass, and acceleration is introduced qualitatively, with a central relationship expressed as:
定性地引入连接力、质量和加速度的关键公式，核心关系表示为：
F = m × a
Where F is the net force, m is mass, and a is acceleration. For Year 7, students focus on understanding that larger forces cause greater changes in motion, and that forces can cause objects to stretch, compress, or bend.
其中 F 为合力，m 为质量，a 为加速度。对于七年级来说，学生重点理解较大的力会导致更显著的运动变化，以及力可以使物体拉伸、压缩或弯曲。
Structural engineering concepts are explored through activities like building bridges from spaghetti or designing towers from straws. Students learn about tension, compression, and torsion, and how shapes such as triangles add strength to structures.

5. Energy and Power | 能量与动力
Energy is a unifying theme in engineering. Year 7 learners study different forms of energy – kinetic, potential, thermal, light, sound, and electrical – and understand that energy can be transferred from one form to another but cannot be created or destroyed.
能量是工程学中一个统一性主题。七年级学生学习不同形式的能量——动能、势能、热能、光能、声能和电能——并理解能量可以从一种形式转化为另一种形式，但无法被创造或消灭。
ncept of power as the rate of energy transfer is introduced, often using the relationship:
他们探索简单的能量链，例如电池点亮灯泡（化学能 → 电能 → 光和热）。引入功率作为能量传递速率的这一概念，常常通过以下关系式：
P = E ÷ t
Where P is power in watts (W), E is energy in joules (J), and t is time in seconds (s). Students apply this by calculating how long a device can run on a given amount of energy.
其中 P 为功率（瓦特 W），E 为能量（焦耳 J），t 为时间（秒 s）。学生通过计算设备在给定能量下能运行多长时间来应用这一公式。
Renewable and non-renewable energy sources are discussed, linking to environmental engineering and the importance of sustainable design.

6. Electricity and Simple Circuits | 电与简单电路
Electrical engineering basics form a significant part of the Year 7 syllabus. Students learn about current, voltage, and resistance, and how to construct simple series and parallel circuits using batteries, wires, bulbs, and switches.
电气工程基础构成了七年级课程的重要部分。学生学习电流、电压和电阻，以及如何使用电池、导线、灯泡和开关构建简单的串联与并联电路。
They are taught to draw circuits using standard symbols and to measure current with an ammeter (connected in series) and voltage with a voltmeter (connected in parallel). The fundamental relationship between voltage, current, and resistance is given by Ohm's law:
他们学习使用标准符号绘制电路图，并使用电流表（串联）测量电流，使用电压表（并联）测量电压。电压、电流和电阻之间的基本关系由欧姆定律给出：
V = I × R
Where V is voltage in volts (V), I is current in amperes (A), and R is resistance in ohms (Ω). In Year 7, calculations focus on using the formula to find any one variable when the other two are given.
其中 V 为电压（伏特 V），I 为电流（安培 A），R 为电阻（欧姆 Ω）。在七年级，计算的重点是在已知两个变量的情况下，使用公式求出第三个变量。
Practical work includes investigating how adding more batteries affects bulb brightness or how resistance changes when the length of a wire is varied. Safety with electricity is heavily emphasised.
实践活动包括探究增加更多电池对灯泡亮度的影响，或改变导线长度时电阻如何变化。用电安全被重点强调。
7. Mechanical Systems | 机械系统
Mechanical systems introduce levers, pulleys, gears, and linkages. Students learn how these simple machines can change the direction or magnitude of a force, making work easier. Mechanical advantage is introduced qualitatively, often with hands-on experiments using lever arms and pulleys.
