1. Understanding the SQA Year 7 Science Exam Structure | 了解 SQA Year 7 科学考试结构
The SQA Year 7 Science exam is designed to assess a broad range of scientific knowledge and skills across Biology, Chemistry, and Physics. The test typically lasts 60 minutes and is worth a total of 40 marks.
SQA Year 7 科学考试旨在评估生物、化学和物理领域的广泛科学知识与技能。考试通常时长60分钟，总分40分。
The paper is divided into three sections: Section A consists of 10 multiple‑choice questions (10 marks), Section B contains short‑answer questions worth 20 marks, and Section C features extended response or data‑analysis questions worth 10 marks.
试卷分为三个部分：A部分包括10道选择题（10分），B部分包含简答题（20分），C部分为扩展回答或数据分析题（10分）。
Past papers show that each science discipline receives approximately one‑third of the marks, ensuring a balanced coverage of topics.
历年真题显示，每一科学学科大约占有三分之一的分数，确保全面覆盖主题。
2. Decoding the Marking Scheme | 破解评分方案
Understanding how marks are awarded is crucial for exam success. Marks are often split between knowledge recall (AO1), application of knowledge (AO2), and scientific enquiry (AO3).
理解评分标准对考试成功至关重要。分数通常分为知识回忆（AO1）、知识应用（AO2）和科学探究（AO3）。
For instance, a 'describe' command requires stating facts, whereas 'explain' asks for a reason or mechanism. A 'calculate' question needs a correct final answer with units.
例如，“描述”命令要求陈述事实，而“解释”要求给出原因或机制。“计算”题需要给出正确的最终答案并标注单位。
Many students lose marks by not reading the command word carefully. Always underline it in the question.
许多学生因没有仔细阅读命令词而失分。务必在题目中将其画线标注。
3. Biology: Cells, Body Systems and Reproduction | 生物：细胞、身体系统与生殖
Cell structure is one of the most frequently tested biology topics. A typical past‑paper question asks: 'Label the parts of an animal cell and a plant cell.' You must know the nucleus, cytoplasm, cell membrane, cell wall, chloroplasts, and vacuole.
细胞结构是生物最常考的主题之一。一道典型的历年真题是：“标记动物细胞和植物细胞的各个部分。”你必须了解细胞核、细胞质、细胞膜、细胞壁、叶绿体和液泡。
Another common question: 'State one function of the cell wall.' Answer: It provides support and maintains the shape of the plant cell.
另一个常见问题：“说出细胞壁的一个功能。”答案：它提供支持并维持植物细胞的形状。
Body systems such as the respiratory and circulatory systems also appear. Candidates are asked to describe the path of oxygen from the air into the blood.
呼吸系统和循环系统等身体系统也会出现。考生需描述氧气从空气进入血液的路径。
In reproduction, Year 7 questions focus on the differences between sexual and asexual reproduction and the basic structures of flowers.
在生殖方面，Year7 问题侧重有性生殖和无性生殖的区别以及花的基本结构。
4. Biology: Ecosystems and Interdependence | 生物：生态系统与相互依存
Ecosystem questions require drawing food chains and webs. A classic question: 'Construct a food chain using the following organisms: grass, rabbit, fox.'
生态系统题目要求绘制食物链和食物网。经典问题：“用以下生物构建一条食物链：草、兔、狐狸。”
point in the direction of energy flow: grass → rabbit → fox. Always start with a producer.
确保箭头指向能量流动的方向：草→兔→狐狸。始终以生产者开头。
Questions may also ask about the effect of removing one species. Answer: it disrupts the balance, affecting other populations.
题目还可能询问移除某一物种的影响。回答：它会破坏平衡，影响其他种群。
5. Chemistry: Particles, States and Changes | 化学：粒子、状态与变化
The particle model is used to explain properties of solids, liquids, and gases. Past papers ask: 'Explain why a liquid can flow but a solid cannot.'
粒子模型用于解释固体、液体和气体的性质。真题问：“解释为什么液体可以流动而固体不能。”
Answer: In liquids, particles are close but can slide past each other; in solids, particles are fixed in position and only vibr
