📚 Year 7 SQA Science: Transition Guide | SQA 7年级科学：升学衔接指南
Moving from Primary to Secondary school is an exciting step, especially in science. In Scotland, Year 7 usually marks your first year of secondary school (S1), where you begin a more structured exploration of biology, chemistry and physics under the SQA framework. This guide is designed to help you understand what to expect, how to build on your existing knowledge, and the key skills you will need to become a confident young scientist.
从小学升入中学是激动人心的一步，科学课尤其如此。在苏格兰，七年级通常是你进入中学的第一年（S1），在这里你将在 SQA 框架下，更系统地探索生物、化学和物理。本指南旨在帮助你了解课程内容、如何在你已有知识的基础上进一步提高，以及成为一名自信的小科学家所需的关键技能。
1. Welcome to Year 7 Science | 欢迎来到七年级科学
Year 7 Science is all about curiosity. You will ask questions about the world around you and learn how to find answers through experiments. Your teacher will encourage you to think like a scientist – making observations, forming hypotheses and testing ideas. This year you will start to use more advanced equipment and record results in a formal way. It is normal to feel a little nervous, but remember that every great scientist started exactly where you are now.
七年级科学的核心是好奇心。你将就周围的世界提出问题，并学习如何通过实验寻找答案。你的老师会鼓励你像科学家一样思考——进行观察、提出假设并检验想法。这一年你将开始使用更先进的设备，并以正式的方式记录结果。感到有些紧张是正常的，但请记住，每一位伟大的科学家都曾站在你现在的起点上。
2. The Scientific Method | 科学方法
The scientific method is a step-by-step process that helps us investigate the natural world. It usually begins with an observation, which leads to a question. You then form a hypothesis – an educated guess that you can test. After designing a fair experiment, you collect data, analyse your results and draw a conclusion. In Year 7, you will practise each of these steps in simple investigations, learning to distinguish between ‘results’ and ‘conclusions’.
科学方法是一个帮助我们研究自然世界的循序渐进的过程。它通常始于观察，从而引出一个问题。然后你提出假设——一个可以进行检验的有根据的猜测。在设计了一个公平的实验后，你收集数据、分析结果并得出结论。在七年级，你将在简单的探究中练习上述每一步，学会区分“结果”和“结论”。
3. Laboratory Safety First | 实验室安全第一
Before you carry out any experiment, you must understand how to stay safe in the lab. Always follow your teacher’s instructions, tie back long hair and wear safety goggles when necessary. Never eat, drink or run in the laboratory. You will learn to recognise hazard symbols on chemical containers, such as flammable, corrosive and irritant. Good safety habits start on day one and will protect you and your classmates throughout your secondary science journey.
在进行任何实验之前，你必须了解如何在实验室保持安全。始终听从老师的指导，扎起长发，必要时佩戴护目镜。绝不在实验室里吃喝或奔跑。你将学会识别化学容器上的危险标志，如易燃、腐蚀性和刺激性。良好的安全习惯从第一天开始养成，并将在此后整个中学科学学习过程中保护你和你的同学。
4. Measurement and Units | 测量与单位
rams (g), volume in litres (L) or millilitres (mL), and time in seconds (s). Temperature is measured in degrees Celsius (°C). Year 7 expects you to choose the correct measuring instrument, read scales accurately, and convert between units, for example 1 m = 100 cm and 1 L = 1000 mL.
在科学中，我们使用标准单位，以确保每个人都以相同的方式记录数据。你将使用米（m）测量长度，使用千克（kg）或克（g）测量质量，使用升（L）或毫升（mL）测量体积，使用秒（s）测量时间。温度则以摄氏度（°C）为单位。七年级要求你选择合适的测量仪器，准确读取刻度，并进行单位换算，例如 1 m = 100 cm，1 L = 1000 mL。
| Quantity | 量 | Common Unit | 常用单位 | Instrument | 仪器 |
|---|---|---|
| Length | 长度 | metre (m) | 米 | Ruler / Metre stick | 尺子 / 米尺 |
| Mass | 质量 | kilogram (kg), gram (g) | 千克, 克 | Digital balance | 电子天平 |
| Volume | 体积 | litre (L), millilitre (mL) | 升, 毫升 | Measuring cylinder | 量筒 |
| Temperature | 温度 | degree Celsius (°C) | 摄氏度 | Thermometer | 温度计 |
| Time | 时间 | second (s) | 秒 | Stopwatch | 秒表 |
5. Observing and Recording Data | 观察与记录数据
Observation is the foundation of all scientific work. In Year 7, you will learn to use your senses carefully, but also to extend them with tools like microscopes and data loggers. When you record data, neatness matters. Results tables should have clear headings with units; graphs should be drawn with a pencil and labelled axes. You will start using line graphs and bar charts to present your findings visually. Remember, a good scientist never changes data to fit their prediction.
观察是所有科学工作的基础。在七年级，你将学会仔细运用感官，同时也会借助显微镜和数据记录仪等工具来延伸感官。记录数据时，整洁非常重要。结果表格应有清晰的标题及单位；图表应用铅笔绘制，并标注坐标轴。你将开始使用折线图和条形图来直观地展示你的发现。请记住，优秀的科学家绝不会为了迎合预测而改动数据。
6. Key Concepts in Biology | 生物学关键概念
animal cells. You will explore how the human body works, including the respiratory, circulatory and digestive systems. The concept of ecosystems, food chains and how energy flows from the Sun to producers and consumers will also be covered. Pupils often carry out an investigation into photosynthesis, using the simple equation: carbon dioxide + water → glucose + oxygen.
七年级的生物会带你走进生命世界。你将学习细胞是生命的基本单位，了解植物细胞与动物细胞的区别。你也会探索人体如何运作，包括呼吸系统、循环系统和消化系统。生态系统、食物链以及能量如何从太阳流向生产者和消费者的概念也将涉及。同学们经常会进行光合作用的探究，使用这个简单方程式：二氧化碳 + 水 → 葡萄糖 + 氧气。
CO₂ + H₂O → C₆H₁₂O₆ + O₂
二氧化碳 + 水 → 葡萄糖 + 氧气
7. Key Concepts in Chemistry | 化学关键概念
Chemistry helps you understand what substances are made of. You will learn about solids, liquids and gases, and how particles behave in each state. Topics include separating mixtures using filtration, evaporation and distillation. You will be introduced to elements, compounds and the periodic table, recognising common symbols like O for oxygen and Fe for iron. A simple chemical reaction you might investigate is adding an acid to a carbonate, which produces carbon dioxide gas that can turn limewater cloudy.
化学帮助你理解物质是由什么组成的。你将学习固体、液体和气体，以及粒子在每种状态下的行为。课题包括使用过滤、蒸发和蒸馏来分离混合物。你将初步认识元素、化合物和元素周期表，识别常见符号，如 O 代表氧，Fe 代表铁。你可能会探究的一个简单化学反应是向碳酸盐中加入酸，产生能使石灰水变浑浊的二氧化碳气体。
8. Key Concepts in Physics | 物理学关键概念
Physics in Year 7 covers forces, energy and electricity. You will measure forces using a newton meter and investigate how balanced and unbalanced forces affect motion. Energy is explored through heat transfer, insulators and conductors. In electricity, you will build simple circuits, learning the symbols for components such as a bulb, switch and cell. You will measure current and voltage, using the formula:
七年级物理涵盖了力、能量和电。你将使用牛顿计来测量力，并探究平衡力与不平衡力如何影响运动。通过热传递、绝缘体和导体来探索能量。在电学部分，你将搭建简单电路，学习灯泡、开关和电池等元件的符号。你将测量电流和电压，并使用以下公式：
V = I × R (where V is voltage, I is current, R is resistance)
V = I × R（V 是电压，I 是电流，R 是电阻）
This formula will be introduced gradually, often through practical activities with series circuits.
这一公式将通过串联电路的实际活动逐步引入。
9. Variables in Experiments | 实验中的变量
Understanding variables is key to planning a fair test. There are three types of variables you need to know: the independent variable (the one you change), the dependent variable (the one you measure) and the control variables (everything else you keep the same). For example, if you test how temperature affects the rate of dissolving, the temperature is the independent variable, the time taken to dissolve is the dependent variable, and the amount of solute, volume of solvent and stirring speed are control variables.
理解变量是设计公平实验的关键。你需要了解三种变量：自变量（你改变的那个）、因变量（你测量的那个）和控制变量（你保持不变的其他所有因素）。例如，如果你测试温度如何影响溶解速率，温度是自变量，溶解所需的时间是因变量，溶质的量、溶剂的体积和搅拌速度则是控制变量。
| Variable Type | 变量类型 | Definition | 定义 | Example | 示例 |
|---|---|---|
| Independent | 自变量 | The factor you deliberately change | 你有意改变的因素 | Temperature of water | 水温 |
| Dependent | 因变量 | The factor you measure | 你测量的因素 | Time for sugar to dissolve | 糖溶解的时间 |
| Control | 控制变量 | Factors kept constant | 保持不变的因素 | Amount of sugar, volume of water, stirring | 糖的量、水的体积、搅拌 |
10. Drawing Conclusions and Evaluating | 得出结论与评估
Once you have collected your data, it is time to make sense of it. A conclusion states whether your results support your hypothesis. It should refer to the data and explain any patterns you see. In Year 7, you also start to evaluate your method: was it a fair test? Were there any anomalies? How could the experiment be improved? This critical thinking skill is just as important as getting the ‘right’ answer.
收集好数据后，就该理解数据的含义了。结论说明你的结果是否支持你的假设。它应引用数据，并解释你观察到的任何规律。在七年级，你还会开始评估你的方法：这是一个公平的测试吗？是否存在异常值？实验如何改进？这种批判性思维技能与得到“正确”答案同等重要。
11. Using Models in Science | 在科学中使用模型
Scientists often use models to explain things that are too small, too large or too complex to observe directly. In Year 7, you will use particle models to explain states of matter, the solar system model to understand planetary motion, and circuit diagrams as models for real electrical pathways. A good model simplifies reality but still helps you make predictions. You will learn that all models have limitations, and discussing these limitations is part of real scientific thinking.
科学家常使用模型来解释那些因太小、太大或过于复杂而无法直接观察的事物。在七年级，你将使用粒子模型解释物质的状态，使用太阳系模型理解行星运动，以及使用电路图作为实际电路通路的模型。一个好的模型能简化现实，同时仍能帮助你做出预测。你将学到所有模型都有局限性，而讨论这些局限性正是真正科学思维的一部分。
12. Building Curiosity and Questions | 培养好奇心与提问
The best scientists are endlessly curious. In Year 7, you are encouraged to ask 'why', 'what if' and 'how' questions beyond the classroom. Whether you are watching a candle burn, observing a plant on the windowsill or wondering why the sky is blue, keep that curiosity alive. Write down your questions in a science journal. The transition into secondary science is not just about learning facts – it is about growing a scientific way of thinking that will last a lifetime.
最优秀的科学家永远充满好奇。在七年级，我们鼓励你在课堂之外提出“为什么”、“如果……会怎样”以及“怎样”的问题。无论是观察蜡烛燃烧、窗台上的植物，还是思考天空为什么是蓝色的，都要保持这份好奇心。将你的问题写在科学日记里。进入中学科学的衔接不仅仅是学习知识点——更是培养一种将伴随你一生的科学思维方式。
