1. Curriculum Overview and Aims | 课程框架与学习目标
Year 7 CIE Chemistry forms part of the Cambridge Lower Secondary Science curriculum, typically taught to students aged 11–12. The syllabus is designed to build a strong foundation in scientific enquiry, chemical knowledge, and understanding of the world around us. At this stage, chemistry is integrated with biology and physics under a single Science course, but the chemical content has its own set of clear learning objectives. The main aim is to spark curiosity while developing practical skills such as observation, measurement, and data interpretation.
Year 7 CIE 化学是剑桥初中科学课程的一部分，通常面向 11–12 岁的学生。该课程旨在为科学探究、化学知识以及对周围世界的理解打下坚实基础。在这一阶段，化学与生物、物理整合为一门科学课，但化学内容有独立明确的学习目标。主要目的是激发好奇心，同时培养观察、测量和数据分析等实践技能。
Throughout the year, learners are encouraged to link chemical concepts to everyday life. They explore why materials behave in certain ways, how substances can be identified and separated, and what happens during simple chemical changes. The syllabus also emphasises scientific literacy, so students learn to use appropriate terminology and present findings in tables, graphs, and written conclusions.
在整个学年中，学生被鼓励将化学概念与日常生活联系起来。他们探索为何材料会有特定的行为，如何识别和分离物质，以及简单化学变化中发生了什么。教学大纲还强调科学素养，因此学生需要学会使用恰当的术语，并用表格、图表和书面结论呈现发现。
2. Scientific Enquiry and Practical Skills | 科学探究与实验技能
Before diving into specific chemical content, the syllabus embeds scientific enquiry as a continuous thread. You will learn how to ask testable questions, design fair experiments, and control variables. For example, when investigating how temperature affects the speed of dissolving, you will decide which factors to keep the same and which to change.
在进入具体的化学内容之前，教学大纲将科学探究作为一条贯穿始终的主线。你将学习如何提出可测试的问题、设计公平实验并控制变量。例如，在研究温度如何影响溶解速度时，你需要决定哪些因素保持不变，哪些因素可以改变。
Practical work in Year 7 chemistry often involves using simple apparatus like beakers, measuring cylinders, thermometers, and Bunsen burners. Safety is a top priority; you will practise lighting a Bunsen burner safely, wearing goggles, and tying back long hair. Recording observations accurately and presenting results in neat tables are key skills assessed in both classwork and Checkpoint tests.
Year 7 化学的实践操作常常会用到烧杯、量筒、温度计和本生灯等简单器材。安全是重中之重；你将练习安全点燃本生灯、佩戴护目镜并束好长发。准确记录观察结果并用整洁的表格呈现数据，是课堂作业和 Checkpoint 测试中评估的关键技能。
3. States of Matter and Particle Theory | 物质状态与粒子理论
One of the first major topics is the three states of matter: solid, liquid, and gas. You will describe their properties in terms of shape, volume, and compressibility. The syllabus then introduces the particle model to explain these properties. Solids have a fixed shape because particles are held tightly in a regular arrangement and can only vibrate in place. Liquids have a fixed volume but take the shape of their container because particles can move past each other. Gases have no fixed shape or volume and can be compressed because particles are far apart and move rapidly in all directions.
首要的核心主题之一是物质的三种状态：固态、液态和气态。你需要从形状、体积和可压缩性等方面描述它们的性质。随后大纲引入粒子模型来解释这些性质。固体有固定形状，因为粒子被紧紧固定在规则排列中，只能原地振动。液体体积固定但形状随容器而变，因为粒子可以互相滑动。气体没有固定的形状和体积，可以被压缩，因为粒子相距很远并朝各个方向快速运动。
You will also explore changes of state, such as melting, freezing, boiling, evaporating, condensing, and sublimation. Importantly, the syllabus stresses that these are physical changes, not chemical changes, because no new substances are formed. Plotting a heating or cooling curve and identifying melting points and boiling points from the graph are typical practical exercises.
你还会探究状态变化，如熔化、凝固、沸腾、蒸发、冷凝和升华。值得注意的是，教学大纲强调这些是物理变化而非化学变化，因为没有新物质生成。绘制加热或冷却曲线并从图表中识别熔点和沸点，是典型的实践活动。
4. Elements, Compounds and Mixtures | 元素、化合物与混合物
Year 7 introduces the idea that all matter is made from elements. An element is a pure substance that cannot be broken down into simpler substances by chemical means. The syllabus expects you to recognise that each element has a name and a chemical symbol, such as O for oxygen and Fe for iron. Compounds form when two or more elements chemically combine in fixed proportions; for example, water (H₂O) is a compound made of hydrogen and oxygen.
Year 7 引入了所有物质都由元素组成的观念。元素是一种无法通过化学方法分解成更简单物质的纯物质。大纲要求你认识到每种元素都有名称和化学符号，如 O 代表氧，Fe 代表铁。当两种或多种元素以固定比例化合时，便形成了化合物；例如水 (H₂O) 是由氢和氧组成的化合物。
Mixtures, in contrast, consist of two or more substances mixed together but not chemically combined. Air is a mixture of gases, and seawater is a mixture of water, salts, and other dissolved substances. You will learn to distinguish between elements, compounds, and mixtures using particle diagrams. The ability to interpret these diagrams is frequently tested.
相反，混合物由两种或多种物质混合而成，但它们之间没有发生化学结合。空气是气体的混合物，海水则是水、盐和其他溶解物的混合物。你将学习用粒子示意图来区分元素、化合物和混合物。解读这类示意图的能力经常会被考查。
5. Atoms, Molecules and the Periodic Table | 原子、分子与元素周期表
At a basic level, Year 7 chemistry touches on the structure of an atom, introducing the nucleus, protons, neutrons, and electrons. You will learn that atoms are the smallest particle of an element that can take part in a chemical reaction. A molecule is a group of two or more atoms bonded together. Using simple molecular models, you will build representations of common substances like oxygen (O₂) and carbon dioxide (CO₂).
在基础水平上，Year 7 化学涉及原子的结构，介绍原子核、质子、中子和电子。你将学到原子是元素能参与化学反应的最小粒子。分子是由两个或多个原子结合而成的集合体。通过简单的分子模型，你会搭建氧气 (O₂) 和二氧化碳 (CO₂) 等常见物质的模型。
The Periodic Table is introduced as a map of all known elements. You will identify the positions of metals and non-metals, locate Group 1 and Group 7, and recognise that elements in the same group have similar properties. Although detailed trends are covered later in Cambridge IGCSE, at this stage students simply become familiar with the layout and the symbols of the first 20 elements.
元素周期表被引入，作为所有已知元素的图谱。你将识别金属和非金属的位置，找到第 1 族和第 7 族，并认识到同族元素具有相似的性质。尽管详细的周期律要到剑桥 IGCSE 阶段才会深入探讨，但现阶段学生只需熟悉周期表的布局以及前 20 个元素的符号。
6. Metals and Non-Metals | 金属与非金属
Distinguishing between metals and non-metals is a core skill in Year 7. You will compare their physical properties: metals are typically shiny, good conductors of heat and electricity, malleable, and ductile. Non-metals are often dull, brittle when solid, and poor conductors. The syllabus also asks you to link these properties to everyday uses — copper in electrical wires, aluminium in foil, and plastics as insulators.
区分金属与非金属是 Year 7 的一项核心技能。你将要比较它们的物理性质：金属通常有光泽，是热和电的良导体，具有延展性和韧性。非金属往往没有光泽，固态时易碎，导热导电性差。大纲还要求你将性质与日常用途联系起来——电线使用铜，铝用于箔纸，塑料则作为绝缘体。
Chemical properties are also introduced through reactions with oxygen. You will observe that many metals react with oxygen to form metal oxides, which are often basic. Non-metals produce acidic oxides when they burn in oxygen. Simple experiments, like burning magnesium ribbon to produce magnesium oxide, make this concept tangible.
通过金属与氧气的反应，化学性质也被引入。你将观察到许多金属与氧气反应生成金属氧化物，这些氧化物通常是碱性的。非金属在氧气中燃烧则生成酸性氧化物。像点燃镁条生成氧化镁这类简单实验，让这一概念变得具体可感。
7. Everyday Chemical Reactions | 常见的化学反应
mperature change, effervescence, or the formation of a precipitate. Word equations become the standard way to represent reactions — for example, ‘methane + oxygen → carbon dioxide + water’.
化学反应的观念是基础中的基础。你将学习通过观察颜色变化、温度变化、冒泡或沉淀生成等迹象来判断反应是否发生。文字方程式成为表示反应的标准方式，例如“甲烷 + 氧气 → 二氧化碳 + 水”。
Year 7 covers a range of simple reactions: combustion of fuels, thermal decomposition of carbonates, and the reaction of acids with metals. You will also explore the energy changes accompanying reactions, classifying them as exothermic (releasing heat) or endothermic (absorbing heat). Practical investigations, such as adding magnesium to hydrochloric acid and measuring the temperature rise, reinforce these ideas.
Year 7 涵盖一系列简单反应：燃料的燃烧、碳酸盐的热分解，以及酸与金属的反应。你还将探究伴随反应的能量变化，将它们归类为放热反应（释放热量）或吸热反应（吸收热量）。诸如将镁加入盐酸并测量温度升高等实践探究活动，会强化这些概念。
8. Acids and Alkalis | 酸与碱
The syllabus introduces acids and alkalis as chemical opposites. Common laboratory acids like hydrochloric acid, sulfuric acid, and nitric acid are discussed alongside everyday acids such as vinegar and citrus juices. Alkalis, which are soluble bases, include sodium hydroxide and household ammonia. You will learn that these substances can be harmful and must be handled with care, using appropriate safety measures.
教学大纲将酸和碱作为化学对立物来介绍。实验室常见的酸如盐酸、硫酸和硝酸，以及日常生活中的酸如醋和柑橘果汁都会涉及。碱是可溶性的氢氧化物，包括氢氧化钠和家用氨水。你将了解到这些物质可能具有危险性，必须采取适当的安全措施小心处理。
The use of indicators, especially litmus paper, is key to distinguishing between acidic, neutral, and alkaline solutions. You will observe that blue litmus turns red in acid, and red litmus turns blue in alkali. The pH scale is introduced as a measure of acidity or alkalinity, ranging from 0 to 14, with 7 being neutral. Neutralisation – the reaction between an acid and an alkali to produce a salt and water – is often demonstrated through a simple titration or the use of universal indicator.
指示剂的运用，特别是石蕊试纸，是区分酸性、中性和碱性溶液的关键。你将观察到蓝色石蕊在酸中变红，红色石蕊在碱中变蓝。pH 标度被引入作为酸碱性的量度，范围从 0 到 14，7 为中性。中和反应——酸与碱反应生成盐和水——常通过简单滴定或通用指示剂进行演示。
9. Separation Techniques | 分离技术
Mixtures can be separated using physical methods, and Year 7 covers several key techniques. Filtration is used to separate an insoluble solid from a liquid, such as sand from water. Evaporation recovers a dissolved solid by boiling off the liquid, while crystallisation yields pure crystals by gently heating a solution. Simple distillation separates a solvent from a solution by boiling and condensing, and chromatography splits mixtures of coloured substances like inks.
混合物可以通过物理方法分离，Year 7 涵盖了几种重要的技术。过滤用于将不溶性固体从液体中分离出来，例如沙子与水。蒸发通过蒸发掉液体来回收溶解的固体，而结晶则通过缓缓加热溶液来获得纯晶体。简单蒸馏通过沸腾和冷凝将溶剂从溶液中分离出来，色谱法可以分离墨水等有色物质的混合物。
In the lab, you will set up filtration using filter paper and a funnel, and identify the filtrate and residue. Paper chromatography will be used to find out how many different dyes are in a felt-tip pen. Understanding which technique to apply to a given mixture is a common exam-style question, so students are encouraged to think about particle size, solubility, and boiling points.
在实验室里，你将使用滤纸和漏斗搭建过滤装置，并识别滤液和滤渣。纸色谱法将被用于弄清楚一支记号笔中含有多少种不同的染料。理解在给定混合物中应用哪种分离技术是考试中常见的问题类型，因此鼓励学生思考粒子大小、溶解度和沸点等因素。
10. Earth and Atmospheric Chemistry | 地球与大气化学
Cambridge Lower Secondary Chemistry also connects to Earth science. You will learn about the Earth’s structure — crust, mantle, outer core, and inner core — and the rock cycle. The three main rock types (igneous, sedimentary, and metamorphic) are introduced, with simple examples like granite, limestone, and marble. Weathering, erosion, and the formation of fossils provide context for how rocks change over time.
剑桥初中化学也与地球科学相联系。你将学习地球的结构——地壳、地幔、外核和内核——以及岩石循环。三种主要的岩石类型（火成岩、沉积岩和变质岩）被引入，并配有简单的例子，如花岗岩、石灰岩和大理石。风化、侵蚀和化石的形成提供了岩石随时间变化的情境。
The composition of the atmosphere is explored: around 78% nitrogen, 21% oxygen, and small proportions of argon, carbon dioxide, and water vapour. You will discuss the importance of oxygen for respiration and combustion, and the role of carbon dioxide in photosynthesis and as a greenhouse gas. Human impact, such as deforestation and burning fossil fuels, is linked to changes in the atmospheric carbon cycle.
大气的组成也被探讨：约 78% 氮气，21% 氧气，以及少量的氩气、二氧化碳和水蒸气。你将讨论氧气对呼吸和燃烧的重要性，以及二氧化碳在光合作用和作为温室气体方面的作用。人类活动，如森林砍伐和化石燃料燃烧，则与大气碳循环的变化联系起来。
11. Assessment Style and Checkpoint Preparation | 评估形式与 Checkpoint 备考
In most schools following the CIE pathway, Year 7 students take end-of-topic tests and internal examinations. The Cambridge Lower Secondary Checkpoint test, taken at the end of Year 9, assesses cumulative knowledge from Years 7–9. Understanding Year 7 chemistry thoroughly is essential, as concepts are built upon in later years. Checkpoint Science papers contain multiple-choice and structured questions that test knowledge, application, and scientific enquiry.
在遵循 CIE 路径的大多数学校中，Year 7 的学生要参加单元测验和校内考试。剑桥初中 Checkpoint 测试在 Year 9 结束时进行，考查从 Year 7 到 Year 9 的累积知识。透彻理解 Year 7 化学至关重要，因为后续内容均以此为基础。Checkpoint 科学试卷包含选择题和结构化问题，考查知识掌握、应用能力与科学探究。
Questions often require you to interpret data from tables and graphs, describe practical methods, and explain observations using particle theory or energy changes. To prepare, students should regularly practise past Checkpoint questions, make flash cards for key vocabulary, and review practical work. At TutorHao, we provide topic-wise worksheets, video explanations, and mock tests designed precisely around the CIE syllabus, so you can target your weaknesses and track progress.
