4. Chemistry: Atoms and the Periodic Table | 化学：原子与元素周期表
The chemistry modules begin with atomic structure. Students recall that atoms consist of protons, neutrons and electrons, learning about relative charges and masses. They use the nuclear model to understand atomic number and mass number, and calculate the number of subatomic particles in a given atom or ion. Isotopes are defined as atoms of the same element with different numbers of neutrons. Electronic configuration is written using models such as the 2,8,8 arrangement, linking the group number in the periodic table to the number of electrons in the outer shell. This provides a basis for predicting chemical behaviour.
化学模块从原子结构开始。学生需要掌握原子由质子、中子和电子构成，了解它们的相对电荷和质量。运用核模型理解原子序数和质量数，并计算给定原子或离子中的亚原子粒子数量。同位素被定义为质子数相同而中子数不同的同一类原子。电子排布采用 2,8,8 等模型来书写，将元素在周期表中的族序数与最外层电子数联系起来。这为预测化学行为打下了基础。
The development of the periodic table is studied through the contributions of Newlands and Mendeleev, highlighting how Mendeleev left gaps for undiscovered elements. Students examine the arrangement of the modern periodic table and explore the properties of Group 1 (alkali metals), Group 7 (halogens) and Group 0 (noble gases). Trends in reactivity down the groups are explained in terms of electron configuration and attraction between the nucleus and outer electrons. Chemical equations for reactions of alkali metals with water and halogens with alkali metals are practised, linking to observations and redox concepts at a simple level.

5. Chemistry: Bonding and Structure | 化学：键合与结构
This topic examines how atoms combine to form compounds. Ionic bonding is described as the electrostatic attraction between oppositely charged ions, typically formed when a metal transfers electrons to a non-metal. Students draw dot-and-cross diagrams for ionic compounds such as NaCl and MgO, and relate the lattice structure to properties like high melting point and electrical conductivity when molten. Covalent bonding is introduced as the sharing of electron pairs, with examples including H₂, Cl₂, H₂O, NH₃, CH₄ and giant covalent substances like diamond and graphite. Metallic bonding is explained by delocalised electrons and the positive metal ion lattice, linking to malleability and conductivity.
本主题探讨原子如何结合形成化合物。离子键被描述为带相反电荷离子之间的静电吸引力，通常由金属向非金属转移电子形成。学生需绘制 NaCl 和 MgO 等离子化合物的点叉图，并将晶格结构与高熔点、熔融态导电等性质相联系。共价键被介绍为电子对的共享，典型例子包括 H₂、Cl₂、H₂O、NH₃、CH₄ 以及金刚石和石墨等巨型共价物质。金属键则通过离域电子和正离子晶格来解释，进而关联到金属的延展性和导电性。
The relationship between bonding, structure and the bulk properties of materials is a unifying theme. Simple molecular substances have low melting and boiling points due to weak intermolecular forces, whereas giant covalent structures have very high melting points. Graphite conducts electricity because of delocalised electrons between layers, a property used in electrodes. Nanoscience and nanoparticles are also introduced, linking to their high surface area to volume ratio and potential applications in medicine, electronics and cosmetics. Students evaluate risks and benefits of nanoparticles, developing critical thinking about new technologies.
键合、结构与物质宏观性质之间的关系是一个贯穿始终的主题。简单分子物质由于分子间作用力较弱，熔沸点较低，而巨型共价结构则具有极高的熔点。石墨因其层间存在离域电子而能导电，这一特性被用于电极制造。纳米科学和纳米粒子也被引入，将其高比表面积和潜在应用（如医疗、电子和化妆品领域）联系起来。学生需评估纳米粒子的风险与收益，培养对新技术的批判性思维。
6. Chemistry: Quantitative Chemistry and Reactions | 化学：定量化学与反应
Quantitative chemistry builds mathematical confidence. Students learn the law of conservation of mass and use it to balance symbol equations. They calculate relative formula mass (Mᵣ) from given atomic masses and determine the mass of a reactant or product using balanced equations. The mole is introduced as a unit for amount of substance, with the key equation moles = mass ÷ Mᵣ. Concentration calculations, including converting between mol/dm³ and g/dm³, are practised. Students also perform titrations as a required practical, applying the formula concentration₁ × volume₁ = concentration₂ × volume₂ to find unknown concentrations.
定量化学旨在建立数学计算的自信。学生需学习质量守恒定律，并运用该定律配平符号方程式。根据已知原子量计算相对式量（Mᵣ），并利用配平的方程式求出反应物或生成物的质量。引入摩尔作为物质的量的单位，关键计算公式为 摩尔数 = 质量 ÷ Mᵣ。练习浓度计算，包括 mol/dm³ 与 g/dm³ 之间的换算。学生还将完成滴定这一必做实验，应用公式 浓度₁ × 体积₁ = 浓度₂ × 体积₂ 来求算未知浓度。
Chemical reactions extend to acids, alkalis and electrolysis. Students investigate the pH scale, neutralisation reactions, and methods for making soluble salts, such as reacting an acid with an insoluble base or a metal. The redox processes underlying electrolysis are introduced: in molten compounds, cations move to the cathode and anions to the anode. For aqueous solutions, discharge rules are applied, considering relative reactivity and concentration. Electroplating and the extraction of aluminium are key industrial applications. Required practicals include electrolysis of aqueous solutions and measuring the energy change of reactions to classify them as exothermic or endothermic.
化学反应部分延伸至酸、碱和电解。学生将探究 pH 标度、中和反应以及可溶性盐的制备方法，例如用酸与不溶性碱或金属反应。介绍电解过程中涉及的氧化还原原理：在熔融化合物中，阳离子向阴极移动，阴离子向阳极移动。对于水溶液，应用放电顺序规则，并考虑相对活性和浓度的影响。电镀和铝的提取是重要的工业应用实例。必做实验包括电解水溶液，以及通过测量反应中的能量变化来判断是放热反应还是吸热反应。
7. Physics: Energy Stores and Transfers | 物理：能量储存与转移
Energy is one of the most fundamental topics in physics. Students identify different energy stores – kinetic, thermal, chemical, gravitational potential, elastic potential, electromagnetic and nuclear – and describe how energy is transferred between stores via heating, waves, electric current and mechanical work. The concept of conservation of energy is reinforced, and the idea that energy is never created or destroyed underpins all calculations. sankey diagrams are drawn to show energy transfers and to calculate efficiency using efficiency = useful output energy transfer ÷ total input energy transfer.
能量是物理学中最基础的主题之一。学生需要识别不同的能量储存形式——动能、热能、化学能、重力势能、弹性势能、电磁能和核能——并描述能量如何通过加热、波、电流和机械做功在储存之间转移。能量守恒的概念被反复强调，能量既不会凭空产生也不会凭空消失的想法是所有计算的基础。学生绘制桑基图来展示能量转移过程，并使用 效率 = 有用的输出能量转移 ÷ 总输入能量转移 来计算效率。
Calculations involving kinetic energy (Eₖ = ½ m v²), gravitational potential energy (Eₚ = m g h), and work done (W = F s) are essential. Students must be able to rearrange these equations and interpret problems set in real-world contexts, such as falling objects or vehicles braking. The concept of power as the rate of energy transfer (P = E ÷ t) is linked to appliances with given power ratings. A required practical on investigating thermal insulators ties these concepts to experimental design, ensuring students can control variables and draw valid conclusions.
动能（Eₖ = ½ m v²）、重力势能（Eₚ = m g h）和做功（W = F s）的计算是重点。学生必须能够对这些公式进行变形，并解读真实场景中的问题，如下落物体或车辆制动。功率作为能量转移的速率（P = E ÷ t），与具有特定额定功率的电器相关联。一个关于研究隔热材料的必做实验将这些概念与实验设计联系起来，确保学生能够控制变量并得出有效结论。
8. Physics: Electricity and Circuits | 物理：电学与电路
Understanding electricity begins with circuit symbols and series vs. parallel circuits. Current is defined as the rate of flow of charge, and the equation Q = I t relates charge, current and time. In a series circuit, current is the same at all points; in parallel, current divides between branches. Potential difference (voltage) is explained as the energy transferred per unit charge (V = E ÷ Q). Resistance is calculated using R = V ÷ I, and the factors affecting resistance – length of wire, temperature, material – are studied, often through required practicals using wire of different lengths or thicknesses.
电路的学习从电路符号和串联与并联电路的区分开始。电流定义为单位时间内通过导体横截面的电荷量，公式 Q = I t 将电荷、电流和时间联系起来。在串联电路中，各处电流相等；在并联电路中，电流则分配在支路中。电势差（电压）被解释为单位电荷所转移的能量（V = E ÷ Q）。电阻用 R = V ÷ I 计算，而影响电阻的因素——导线长度、温度和材料——则通过使用不同长度或粗细导线的必做实验进行探究。
Ohm’s law is applied to ohmic conductors, and characteristic current–voltage graphs are drawn for a resistor at constant temperature, a filament lamp and a diode. Mains electricity in the UK (230 V, 50 Hz) introduces the differences between direct and alternating current. The function of the live, neutral and earth wires, along with the importance of fuses and circuit breakers for safety, must be understood. Power calculations using P = I V and P = I² R link energy and electricity, allowing students to compare the efficiency and cost-effectiveness of different devices.
欧姆定律适用于欧姆导体，学生需绘制定值电阻、白炽灯和二极管的特性曲线（电流-电压图）。英国的家用交流电（230 V, 50 Hz）引入了直流电和交流电的区别。必须理解火线、零线和地线的作用，以及保险丝和断路器对安全用电的重要性。运用 P = I V 和 P = I² R 进行功率计算，将能量与电学联系起来，使学生能够比较不同电器的能效和性价比。
9. Physics: Particle Model of Matter | 物理：物质的粒子模型
The particle model explains the properties of solids, liquids and gases in terms of arrangement, movement and energy of particles. Density is a crucial concept, calculated using ρ = m ÷ V. Students carry out a required practical to determine the density of regular and irregular solids, as well as liquids, using a ruler and a displacement method. Internal energy is introduced as the total kinetic and potential energy of particles in a system. Changes of state are described in terms of energy transfer that does not change temperature until the state change is complete.
粒子模型从粒子的排列、运动和能量角度解释固体、液体和气体的性质。密度是核心概念，用公式 ρ = m ÷ V 计算。学生需要完成必做实验，使用刻度尺和排水法分别测定规则固体、不规则固体以及液体的密度。内能被定义为系统内所有粒子的动能和势能之和。物态变化被描述为一种不引起温度变化直到变化完成的能量转移过程。
Specific heat capacity and specific latent heat are quantitative topics. The equation ΔE = m c Δθ is used to calculate the energy needed to change temperature, while E = m L is used for changes of state. Students perform a required practical to measure the specific heat capacity of a metallic block, practising control of variables and reduction of energy loss. Particle motion in gases is linked to pressure, explaining how increasing temperature or decreasing volume causes more frequent and forceful collisions with container walls, linking to real-world gas behaviour.
比热容和比潜热属于定量计算主题。方程式 ΔE = m c Δθ 用于计算改变温度所需的能量，而 E = m L 则适用于物态变化。学生需完成测量金属块比热容的必做实验，练习控制变量和减少能量损失。气体中的粒子运动与压力相联系，解释温度升高或体积减小是如何导致粒子与容器壁碰撞更频繁、更强烈，从而关联到真实气体行为。
10. Physics: Forces and Motion | 物理：力与运动
Forces are classified as contact or non-contact, with gravity, electrostatic force and magnetism as examples of the latter. Scalar and vector quantities are distinguished; displacement, velocity, acceleration, force and momentum are vectors, while speed, distance and mass are scalars. Newton’s first, second and third laws form the theoretical backbone. The equation F = m a is applied to scenarios involving balanced and unbalanced forces. Students construct free-body diagrams and calculate resultant forces, explaining how they change an object’s motion.
力可分为接触力和非接触力，重力、静电力和磁力属于后者。标量和矢量得以区分：位移、速度、加速度、力和动量是矢量，而速率、距离和质量是标量。牛顿第一、第二和第三定律构成理论的支柱。公式 F = m a 应用于平衡力与非平衡力的场景。学生需要绘制受力示意图，并计算合力，解释合力如何改变物体的运动状态。
Motion is analysed using graphs and equations. Distance–time graphs allow calculation of speed; velocity–time graphs give acceleration and distance travelled (area under the graph). Key equations include v = u + a t, s = u t + ½ a t² and v² = u² + 2 a s for uniform acceleration. Stopping distance is broken into thinking distance and braking distance, with factors affecting each. The concept of momentum (p = m v) and its conservation during collisions and explosions is introduced, preparing students for higher-tier understanding.
运用图像和公式来分析运动。距离-时间图可用于计算速率；速度-时间图则可得出加速度和运动距离（图线下方面积）。关键公式包括匀加速运动的 v = u + a t、s = u t + ½ a t² 和 v² = u² + 2 a s。制动距离分为思考距离和制动距离，并讨论各自的影响因素。动量（p = m v）及其在碰撞和爆炸中的守恒也被引入，为高阶层学习做好准备。
11. Required Practicals Overview | 必做实验概览
The Eduqas specification identifies a set of core practicals that must be carried out by students. These experiments develop skills in manipulating apparatus, making measurements, recording data and evaluating results. In biology, key practicals include using a light microscope to observe cells, investigating the effect of pH or temperature on enzyme activity, and testing for starch, sugars, proteins and lipids. In chemistry, students make a soluble salt, carry out electrolysis, perform titrations and investigate exothermic/endothermic reactions. Physics requires experiments on specific heat capacity, thermal insulators, resistance of a wire, and determining density. Each practical is underpinned by safety considerations and careful variable control.
