📚 Year 7 SQA Science: Exam Techniques and Marking Criteria | Year 7 SQA 科学：答题技巧与评分标准
Mastering exam technique is just as important as learning the scientific concepts in Year 7 SQA Science. When you know what examiners are looking for, you can structure your answers to earn every possible mark. This article will guide you through effective strategies and demystify the marking criteria used in assessments, helping you build confidence and achieve success.
掌握答题技巧与学习科学概念同样重要。当你了解阅卷老师的评分标准时，就能有针对性地组织答案，拿到每一个应得的分数。本文将带你掌握高效的答题策略，解读评估中使用的评分标准，帮助你树立信心，取得优异成绩。
1. Understanding the Question Types | 理解题型
Year 7 SQA Science assessments include a variety of question styles. You might encounter multiple-choice questions, short-answer items, data response tasks, and sometimes structured investigation questions. Recognising the type of question helps you decide how much detail to give and what the examiner expects. For instance, a multiple-choice question typically has only one correct answer, so eliminate obviously wrong options first. For a short-answer question, look at the space provided – it hints at the expected length of your response.
Year 7 SQA 科学评估包含多种题型，比如选择题、简答题、数据分析题，有时还有结构化的探究题。识别题目类型有助于你决定答案的详略程度和考官期望。例如，选择题通常只有一个正确答案，先排除明显错误的选项。对于简答题，注意答题空间的长度——这暗示了答案的篇幅要求。
2. Interpreting Command Words | 解读命令词
Command words are the action words in a question that tell you what to do. Getting these right is essential. Common command words include 'state', 'describe', 'explain', 'calculate', 'suggest', 'compare', and 'evaluate'. Each requires a specific type of answer. Below is a table that summarises what each word means and how to respond.
命令词是题目中指示你如何作答的动词，正确理解它们至关重要。常见的命令词有 'state'（陈述）、'describe'（描述）、'explain'（解释）、'calculate'（计算）、'suggest'（建议）、'compare'（比较）和 'evaluate'（评价）。每个词都要求特定的回答方式。下面用表格总结各个命令词的含义及应答方法。
| Command Word | Meaning | Tip for Answering |
|---|---|---|
| State | Give a clear fact or name | No explanation needed – just the answer. |
| Describe | Say what happens or what you see | Include trends, patterns, or observations; often support with data. |
| Explain | Give reasons why or how | Use 'because' and link to scientific ideas. |
| Calculate | Work out the answer using numbers | Show your working and include units. |
| Suggest | Apply your knowledge to a new situation | There may be more than one correct answer; justify your idea. |
| Compare | Describe similarities and differences | Use comparative words like 'higher than', 'whereas'. |
| Evaluate | Discuss strengths and weaknesses or make a judgement | Give both sides and a conclusion. |
Practising with past questions and identifying the command word before you start writing will significantly improve your answers. Even if your science knowledge is correct, failing to follow the command word can cost you marks.
练习时先用历年题目并识别命令词再作答，能显著提升回答质量。即便你的科学知识正确，若未遵循命令词的要求，也可能会丢分。
3. Showing Working in Calculations | 展示计算过程
In calculation questions, marks are awarded for method as well as the final answer. Always write down the formula you are using, substitute the numbers carefully, and then give the result. For example, if you are calculating speed, write:
speed = distance ÷ time
speed = 100 m ÷ 20 s = 5 m/s
Even if you make a small arithmetic mistake, you can still earn marks for the correct method and unit. Without showing your working, a wrong final answer gets zero marks. In SQA assessments, units are almost always required; missing them can lose a mark. Also be mindful of significant figures or decimal places if specified in the question.
在计算题中，过程分和最终答案分同样重要。一定要写出所用的公式，仔细代入数值，再给出结果。例如，计算速度时，你应该写：公式、代入、答案。即使出现小小的算数错误，只要方法正确，仍能获得过程分和单位分；但不展示过程，最终答案错误就得不到分数。在SQA评估中，几乎每道计算题都要求写单位；漏写单位会丢分。此外，如果题目明确要求有效数字或小数位数，也务必遵守。
4. Describing Data and Graphs | 描述数据与图表
Data description questions ask you to identify trends or patterns in tables, bar charts, or line graphs. Use phrases like 'as the independent variable increases, the dependent variable increases/decreases'. Always quote specific numbers from the data to support your description. For example: "The temperature rose from 20 °C to 45 °C in the first 2 minutes, then remained constant." This shows you can read values accurately. Avoid general statements like "it went up" without evidence.
数据描述题要求你识别表格、柱状图或折线图中的趋势或规律。使用诸如“随着自变量增加，因变量增加/减少”这样的表达。始终引用数据中的具体数字来支持你的描述。比如：“温度在前2分钟从20 °C升至45 °C，然后保持稳定。”这表明你能准确读取数值。应避免没有证据的笼统表述，如“它上升了”。
When comparing data sets, mention which set has higher or lower values and by how much. Use comparative language: 'faster than', 'lower than', 'three times as great'. This demonstrates a deep engagement with the data and often earns the full two marks for a 'compare' question.
比较数据集时，要指出哪个数据集数值更高或更低，差距有多大，并运用比较性语言：“比……更快”、“比……低”、“是……的三倍”。这体现出对数据的深入分析，常能在“比较”题中获得满分。
5. Explaining Scientific Concepts | 解释科学概念
Explanation questions test your understanding of cause and effect. You must state what happens and, crucially, why it happens using scientific principles. A good structure is: "This happens because...". For instance, "A balloon expands because the particles inside move faster and spread out, increasing the pressure." The mark scheme rewards linking the observation to a scientific mechanism – look for key words like 'particles', 'force', 'energy transfer', or 'reaction'. In Year 7, you might need to explain changes of state, forces, or basic chemical reactions. Never just repeat the description; always add the reason.
解释题考查你对因果关系的理解。你不仅要陈述发生了什么，更要基于科学原理说明为什么会发生。一个良好的结构是：“这发生是因为……”。例如：“气球膨胀是因为内部粒子运动
