1. Understanding the Cambridge Year 7 Science Curriculum | 理解剑桥七年级科学课程
The Cambridge Lower Secondary Science curriculum for Year 7 is designed to build a firm foundation in scientific knowledge, skills and attitudes. It is organised into four content strands: Biology, Chemistry, Physics, and Earth and Space (often integrated within Physics). Alongside content, the ‘Thinking and Working Scientifically’ strand develops skills such as planning investigations, collecting data, analysing results and evaluating evidence.
剑桥初中七年级科学课程旨在建立坚实的科学知识、技能和态度的基础。它分为四个内容领域：生物、化学、物理，以及地球与太空（通常融入物理教学中）。在内容学习的同时，“科学思维与实践”领域培养诸如规划探究、收集数据、分析结果和评估证据等技能。
Students are encouraged to make connections between different scientific ideas and to apply their understanding to everyday life. Assessment includes regular teacher feedback, end-of-topic tests and informal practical assessments. Familiarising yourself with the curriculum objectives can help you ask the right questions and spot learning opportunities in the world around you.
鼓励学生将不同的科学概念联系起来，并将理解应用到日常生活中。评估包括定期的教师反馈、单元结束测试和非正式的实验评估。熟悉课程目标有助于您提出恰当的问题，并在周围环境中发现学习机会。
2. Biology: Living Things and Life Processes | 生物学：生物与生命过程
In Year 7 biology, students are introduced to the idea that all living organisms are made of cells. They compare plant and animal cells, learning key structures such as the nucleus, cytoplasm, cell membrane, and in plants, the cell wall, chloroplasts and large vacuole.
在七年级生物学中，学生们了解到所有生物体都是由细胞构成的。他们比较植物细胞与动物细胞，学习关键结构，如细胞核、细胞质、细胞膜，以及植物细胞特有的细胞壁、叶绿体和大液泡。
The seven life processes — often remembered by the acronym MRS GREN (Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition) — help students decide whether something is living. Classification of organisms into kingdoms (animals, plants, fungi, etc.) and simple keys are also covered.
七大生命过程——通常用首字母缩写 MRS GREN（运动、呼吸、感应、生长、繁殖、排泄、营养）来帮助记忆——帮助学生判断某物是否具有生命。课程还涉及将生物分类为界（动物界、植物界、真菌界等）以及简单的检索表。
At home, you can encourage your child to observe pond water under a microscope (if available) or examine plant cells from an onion skin. Discussing how seeds grow or why we breathe can deepen understanding of life processes.
在家中，您可以鼓励孩子用显微镜（如有）观察池塘水，或检查洋葱表皮的植物细胞。讨论种子如何生长或我们为什么呼吸，可以加深对生命过程的理解。
3. Chemistry: Particles, Substances and Reactions | 化学：微粒、物质与反应
Year 7 chemistry starts with the particle model of matter. Students learn that all substances are made of tiny particles, and the arrangement and movement of these particles explain the properties of solids, liquids and gases. Key concepts include diffusion and pressure in gases.
七年级化学以物质的微粒模型开始。学生了解到所有物质都由微小的粒子组成，这些粒子的排列和运动解释了固体、液体和气体的性质。关键概念包括气体的扩散和压强。
The difference between elements, compounds and mixtures is introduced. Students explore simple chemical reactions, such as the reaction of an acid with a metal, and learn to write word equations. They also begin to understand neutralisation and the pH scale.
课程介绍了元素、化合物和混合物之间的区别。学生探索简单的化学反应，例如酸与金属的反应，并学习书写文字方程式。他们也开始理解中和反应和 pH 标度。
You can relate these ideas to cooking: melting butter (change of state), baking soda and vinegar (reaction producing carbon dioxide), and mixtures like fruit salad. Point out chemical symbols on food labels or discuss how antacid tablets work.
您可以将这些概念与烹饪联系起来：黄油熔化（状态变化）、小苏打与醋（产生二氧化碳的反应）、以及像水果沙拉这样的混合物。指出食品标签上的化学符号，或讨论抗酸药片的工作原理。
4. Physics: Forces, Energy and the Universe | 物理：力、能量与宇宙
The physics strand introduces forces as pushes or pulls that can change the speed, direction or shape of an object. Students learn to measure forces in newtons, draw force diagrams and understand balanced and unbalanced forces. The effects of friction and gravity are explored.
物理部分将力介绍为能改变物体速度、方向或形状的推或拉。学生学会以牛顿为单位测量力，绘制力的示意图，并理解平衡力和非平衡力。同时探索摩擦力和重力的效应。
Energy is studied through different forms (kinetic, thermal, light, sound, etc.) and the concept of energy transfer. Simple electric circuits with components like cells, bulbs and switches help students grasp current and voltage qualitatively. Basic astronomy topics such as the Solar System and phases of the Moon often appear at this stage.
通过学习不同形式的能量（动能、热能、光能、声能等）和能量转移的概念来研究能量。由电池、灯泡和开关等元件构成的简单电路帮助学生们定性地理解电流和电压。基础天文学专题如太阳系和月相也常在此阶段出现。
Turn everyday situations into physics lessons: ask why a ball stops rolling (friction), or how a seesaw works (moments). Building a simple circuit with a battery and LED or stargazing together can be both fun and educational.
将日常情境转化为物理课：问为什么球会停止滚动（摩擦），或跷跷板如何工作（力矩）。用电池和LED制作简易电路，或者一起观星，既有乐趣又有教育意义。
5. Scientific Enquiry: Thinking and Working Scientifically | 科学探究：科学思维与工作方式
This strand runs through all content and is crucial to Cambridge Science. Students learn to formulate testable questions, identify variables (independent, dependent and control), make predictions and design fair tests. They collect data using standard units and present it in tables and graphs.
这一领域贯穿所有内容，对剑桥科学至关重要。学生学习提出可验证的问题，识别变量（自变量、因变量和控制变量），作出预测并设计公平实验。他们使用标准单位收集数据，并用表格和图表呈现数据。
Analysis involves describing patterns and trends, and drawing conclusions that refer to evidence. Evaluating an investigation includes discussing limitations and suggesting improvements. These skills are assessed through practical work and written examinations.
分析包括描述模式和趋势，并根据证据得出结论。评估探究包括讨论局限性和提出改进建议。这些技能通过实验工作和书面考试进行评估。
Encourage your child to ‘think like a scientist’ by asking ‘What do you notice?’ and ‘What could we change?’ during everyday activities. Help them practise plotting graphs and interpreting simple charts. Even baking can be a fair-test experiment: what happens if we change the amount of baking powder?
鼓励您的孩子像科学家一样思考，在日常生活中问他们“你注意到了什么？”和“我们可以改变什么？”。帮助他们练习绘制图表并解读简单图形。就连烘焙也可以成为一个公平实验：如果我们改变泡打粉的量，会发生什么？
6. Practical Skills and Lab Safety | 实验技能与实验室安全
Practical work is at the heart of science, but safety is paramount. Year 7 students are taught how to recognise common hazard symbols (flammable, corrosive, toxic), follow safety rules, and use laboratory equipment such as Bunsen burners, microscopes and measuring cylinders correctly.
实验工作是科学的核心，但安全至关重要。七年级学生被教导如何识别常见的危险符号（易燃、腐蚀性、有毒），遵守安全规则，并正确使用本生灯、显微镜和量筒等实验室设备。
They learn to measure volumes and masses accurately, observe and record results, and conduct basic separation techniques such as filtration and evaporation. Understanding the safe handling of chemicals and the appropriate response to accidents is part of the curriculum.
他们学习准确测量体积和质量，观察并记录结果，并进行基本分离技术如过滤和蒸发。理解如何安全处理化学品以及应对事故的适当方法也是课程的一部分。
At home, you can reinforce safety consciousness by discussing why we wear seatbelts or handle hot liquids carefully. If you conduct any simple experiments together, always use protective goggles and supervise thoroughly.
在家中，您可以通过讨论为什么我们系安全带或小心处理热液体来加强安全意识。如果一起进行任何简单实验，请务必佩戴防护目镜并全程监督。
7. How to Support Your Child at Home | 如何在家支持孩子
Your role as a parent is not to replace the teacher but to create an environment where science is seen as fascinating and accessible. Regular, short discussions about science topics have a powerful effect. Ask about what they learned in school and listen actively; get them to explain a concept to you — teaching is one of the best ways to learn.
作为家长，您的角色并非取代老师，而是创造一个让科学被视为迷人且容易接近的环境。定期进行简短的科学话题讨论会产生强大效果。询问他们在学校学到了什么，并积极倾听；让他们向您解释一个概念——教授是最好的学习方式之一。
Integrate science into daily life: while cooking, note chemical and physical changes; on a walk, discuss habitats and adaptations; during a thunderstorm, talk about static electricity. Use reputable websites, documentaries (e.g., BBC Bitesize, Cambridge GO) and age-appropriate science books to supplement schoolwork. Encourage curiosity and avoid seeing ‘I don’t know’ as a failure — look up the answer together.
将科学融入日常生活：做饭时，留意化学和物理变化；散步时，讨论栖息地和适应性；雷雨天气时，谈论静电。使用信誉良好的网站、纪录片（如 BBC Bitesize、Cambridge GO）以及适合年龄的科学书籍来补充学校功课。鼓励好奇心，避免将“我不知道”视为失败——一起查找答案。
Help them revise actively by making flashcards, mind maps or short quizzes. Timed practice with past paper questions (even verbally) builds exam confidence. Celebrate effort and progress, not just correct answers.
通过制作记忆卡、思维导图或简短小测验，帮助他们积极复习。用往年真题（哪怕口头提问）进行限时练习，建立考试信心。庆祝努力和进步，而不仅仅是正确答案。
8. Assessment, Resources and Next Steps | 评估、资源与后续步骤
Cambridge Year 7 Science assessment is typically through end-of-unit tests and a progression test at the end of the year (if the school uses Cambridge Lower Secondary Progression Tests). These assess both content knowledge and scientific enquiry skills. Familiarise yourself with the format: multiple-choice, short-answer and structured questions.
剑桥七年级科学评估通常通过单元结束测试和学年末的进步测试（如果学校采用剑桥初中进步测试）进行。这些测试评估内容知识和科学探究技能。熟悉题型：选择题、简答题和结构化问题。
Useful resources include the Cambridge Primary and Lower Secondary Science curriculum frameworks (online), Bitesize KS3 Science, Twinkl, and the ‘Cambridge Science’ learner books. Encourage your child to keep a science journal to record observations and questions. Look ahead to Year 7 key topics and note any areas where extra practice may be beneficial. Most importantly, maintain the joy of discovery — science is about asking questions about the universe we live in.
有用的资源包括剑桥中小学科学课程框架（在线）、Bitesize KS3 科学、Twinkl 以及“剑桥科学”学生用书。鼓励孩子记科学日记，记录观察和问题。展望七年级的关键主题，注意任何可能需要额外练习的领域。最重要的是，保持发现的乐趣——科学就是对我们所生活的宇宙提出问题。
