📚 Mastering the SQA Year 7 Science Report: Structure and Sample | 掌握SQA七年级科学论文写作：框架与范文
Writing a science report is an essential skill for Year 7 pupils following the SQA science curriculum. A well-structured report helps you communicate your investigation clearly, showing how you planned, carried out and analysed an experiment. This article will guide you through a simple yet effective framework, complete with a worked example, so you can write your own reports with confidence.
撰写科学报告是遵循 SQA 科学课程的七年级学生的一项基本技能。一份结构良好的报告能够帮助你清晰地传达你的研究，展示你是如何计划、实施和分析实验的。本文将带你走过一个简单而有效的框架，并配有一个完整的实例，让你能够自信地撰写自己的报告。
1. Understanding the Purpose of a Science Report | 理解科学报告的目的
A science report is not just a piece of homework; it is a record of your scientific thinking. Its purpose is to demonstrate that you can ask a question, plan a fair test, collect reliable data, interpret results and draw a valid conclusion based on evidence.
科学报告不只是一项家庭作业；它是你科学思维的记录。其目的是展示你能够提出问题、规划公平测试、收集可靠数据、解释结果，并依据证据得出有效结论。
Writing in a logical order helps anyone reading your report to understand exactly what you did and why. It also trains you to think like a scientist, focusing on accuracy, fairness and honesty when handling data.
按逻辑顺序写作有助于任何阅读你报告的人清楚了解你做了什么以及为什么这样做。它还训练你像科学家一样思考，在处理数据时注重准确性、公平性和诚实性。
2. Structure of a Year 7 SQA Science Report | 七年级 SQA 科学报告的结构
Every science report you write should follow a clear, step-by-step structure. This helps you stay organised and ensures you do not miss any important detail. The main sections are listed below.
你撰写的每一份科学报告都应遵循清晰、逐步推进的结构。这有助于你保持条理，并确保不会遗漏任何重要细节。主要部分列举如下。
- Title – A short sentence that describes the investigation. 标题 – 描述研究的简短句子。
- Aim – What you are trying to find out. 目标 – 你想要探明什么。
- Hypothesis – Your prediction with a scientific reason. 假设 – 你的预测及其科学依据。
- Variables – The things you change, measure and keep the same. 变量 – 你改变、测量和保持不变的因素。
- Method – A step-by-step list of instructions. 方法 – 逐步的步骤说明列表。
- Results – Your measurements and observations, often in a table. 结果 – 你的测量和观察结果，通常以表格呈现。
- Analysis and Discussion – What your results mean, and any patterns or surprises. 分析与讨论 – 你的结果意味着什么，有哪些模式或意外之处。
- Conclusion – A final answer to your aim, supported by evidence. 结论 – 对你的目标做出的最终回答，且由证据支持。
You may also include an Evaluation section, where you reflect on what went well and what could be improved. For Year 7, focusing on these eight sections first will build an excellent foundation.
你还可以加入一个评估部分，反思哪些方面做得好，哪些可以改进。对于七年级，首先专注于这八个部分将打下扎实的基础。
3. Title and Aim: Setting the Scene | 标题与目标：设定场景
The title should be a clear statement that tells the reader exactly what you investigated. Use key words like 'investigate', 'determine' or 'compare'. For example: 'Investigating how the length of a pendulum affects the time it takes to swing'.
标题应是一个清晰的陈述，准确告诉读者你研究了什么。使用“探究”、“测定”或“比较”等关键词。例如：“探究摆长如何影响其摆动时间”。
The aim is one sentence that starts with 'To investigate...' or 'To find out...'. It must link directly to the title and describe the relationship you are testing. A strong aim: 'To investigate how the mass of a toy car affects the distance it travels down a ramp.'
目标是以“探究……”“或“查明……”开头的一句话。它必须与标题直接相关，并描述你所验证的关系。一个好的目标：“探究玩具车的质量如何影响它沿斜面下滑的距离。”
4. Hypothesis: Making a Prediction | 假设：做出预测
A hypothesis is more than a guess. It is a prediction of what you think will happen, backed up by a simple scientific reason. Use the structure: 'If ... then ... because ...'. For example: 'If I increase the height of the ramp, then the toy car will travel further because it will have more gravitational potential energy to convert into kinetic energy.'
假设不仅仅是猜测。它是你认为会发生什么的预测，并附上一个简单的科学理由。使用这样的结构：“如果……那么……因为……”。例如：“如果我增加斜面的高度，那么玩具车会滑得更远，因为它将有更多的重力势能转化为动能。”
In Year 7, the reasoning can be basic but must connect to the idea you are testing. Avoid writing 'I think it will work'. Instead, explain why your prediction makes scientific sense.
在七年级，理由可以很简单，但必须与你验证的想法联系起来。避免写“我觉得它会成功”。相反，要解释为什么你的预测在科学上是合理的。
5. Variables: Fair Testing | 变量：公平测试
To conduct a fair test, you must identify three types of variable. This shows you understand what to change, what to watch and what to control.
要进行公平测试，你必须明确三种类型的变量。这表明你理解什么需要改变、什么需要观察以及什么需要控制。
- Independent variable – the one you deliberately change. 自变量 – 你有意改变的那个量。
- Dependent variable – the one you measure or observe. 因变量 – 你测量或观察的那个量。
- Control variables – all the factors you keep the same to make the experiment fair. 控制变量 – 你保持不变以确保实验公平的所有因素。
For example, if you are testing how temperature affects the rate at which sugar dissolves, the independent variable is the temperature of the water. The dependent variable is the time it takes for the sugar to dissolve. Control variables include the volume of water, the type of sugar and the stirring method.
例如，如果你正在检验温度如何影响糖的溶解速率，那么自变量是水的温度。因变量是糖完全溶解所需的时间。控制变量包括水的体积、糖的种类和搅拌方式。
6. Method: Step-by-Step Instructions | 方法：分步说明
The method must be written as a numbered list of clear, safe instructions. Use command verbs such as 'Measure', 'Pour', 'Record' and 'Repeat'. Each step should be precise enough that another scientist could repeat your experiment exactly.
方法必须写成一份编号清单，列出清晰、安全的步骤说明。使用“测量”、“倒入”、“记录”和“重复”等 动作词汇。每一步都应足够精确，以便其他科学家能够严格重复你的实验。
Example method for a friction experiment:
摩擦力实验方法示例：
- Place a wooden block on a smooth wooden ramp. 将一个木块放在光滑的木制斜面上。
- Slowly raise one end of the ramp until the block just begins to slide. 缓慢抬高斜面的一端，直到木块刚好开始滑动。
- Measure the angle of the ramp using a protractor. 使用量角器测量斜面的角度。
- Record the angle in a results table. 在结果表中记录下该角度。
- Repeat steps 1–4 for surfaces covered with sandpaper and carpet. 对于覆盖有砂纸和地毯的表面，重复步骤 1 至 4。
Always include a safety note if you are using hot water, sharp objects or heavy equipment. This shows you have considered risks.
如果你使用热水、尖锐物品或沉重设备，始终要加上安全注意事项。这表明你已经考虑到了风险。
7. Results: Presenting Data Clearly | 结果：清晰展示数据
Results record what you actually observed and measured, without interpreting what it means yet. The best way to present numerical data is in a ruled table with clear headings and units.
结果记录的是你实际观察和测量到的内容，暂时不解释其含义。呈现数值数据的最佳方式是用一个带边框的表格，包含清晰的表头和单位。
Here is an example table from an experiment on light and plant growth:
以下是光照与植物生长实验中的一个表格示例：
| Day | 天数 | Height in light (cm) | 光照下高度 (厘米) | Height in dark (cm) | 黑暗下高度 (厘米) |
|---|---|---|
| 1 | 1.2 | 1.2 |
| 3 | 2.6 | 2.0 |
| 5 | 4.5 | 2.8 |
| 7 | 6.8 | 3.3 |
In Year 7 you may also be asked to calculate an average. For example, if you repeated the measurement three times, you add the values and divide by three. You can show the calculation simply.
在七年级，你或许还会被要求计算平均值。例如，如果你重复测量了三次，你把数值相加然后除以三。你可以简单地展示计算过程。
Average = (Trial 1 + Trial 2 + Trial 3) ÷ 3 | 平均值 = (试验1 + 试验2 + 试验3) ÷ 3
8. Analysis and Discussion: Explaining Findings | 分析与讨论：解释发现
This is where you look for patterns and describe what your data tells you. Start by stating the trend. For the plant data above, you might write: 'The plants in the light grew taller each day, while the plants in the dark grew much more slowly.'
在这里，你要寻找规律并描述数据告诉了你什么。首先陈述趋势。对于上面的植物数据，你可以写道：“光照下的植物每天都长得更高，而黑暗中的植物生长慢得多。”
Next, try to explain your results using scientific knowledge. In this case, light is needed for photosynthesis, which produces food for growth. Mention any anomalous results – a measurement that does not fit the trend – and suggest a reason, such as a mistake in reading the ruler.
接下来，尝试用科学知识解释你的结果。在这个例子中，植物需要光进行光合作用，从而制造生长所需的养料。提一下任何异常结果——一个不符合趋势的测量值——并给出可能的原因，比如读错尺子。
Comparing your findings with your hypothesis is crucial. Was your prediction correct? Even if it was not, that is still a valid scientific outcome. Science is about discovering the truth, not about being right all the time.
将你的发现与假设进行比较至关重要。你的预测正确吗？即使不正确，这仍然是一个有效的科学结果。科学在于探索真相，而非总是正确。
9. Conclusion: Answering the Aim | 结论：回答目标
The conclusion is a short, powerful paragraph that gives a definite answer to the aim. It should not introduce new information. Use the structure: 'In conclusion, the results show that...', followed by a summary of the main finding and a reference to the evidence.
结论是一个简短有力的段落，它对目标给出明确答案。不应引入新信息。使用这样的结构：“总之，结果表明……”，接着总结主要发现并提及证据。
For the plant experiment, a strong conclusion would be: 'In conclusion, the results show that light does affect the growth of cress seedlings. By Day 7, the plants in the light had reached an average height of 6.8 cm while the plants in the dark only averaged 3.3 cm. This supports my hypothesis that light is necessary for healthy plant growth because it enables photosynthesis.'
对于那个植物实验，一个强有力的结论是：“总之，结果表明光确实会影响水芹幼苗的生长。到第 7 天，光照下的植物平均高度达到 6.8 厘米，而黑暗中的植物平均只有 3.3 厘米。这支持了我的假设，即光对于植物健康生长是必要的，因为它使光合作用得以进行。”
10. Example Report: Does Light Affect Plant Growth? | 范文示例：光会影响植物生长吗？
Below is a complete, model science report for Year 7. You can use the format as a template for your own investigations.
下面是一份完整的七年级科学报告范本。你可以将此格式用作你自己研究的模板。
Title: Does light affect the growth of cress seedlings?
标题：光会影响水芹幼苗的生长吗？
Aim: To investigate whether light is necessary for the healthy growth of cress plants.
目标：探究光是否是水芹植物健康生长所必需的。
Hypothesis: If cress seedlings are grown in the light, then they will grow taller than seedlings grown in the dark because plants need light for photosynthesis, which produces glucose for growth.
假设：如果水芹幼苗在光照下生长，那么它们会长得比在黑暗中生长的幼苗更高，因为植物需要光进行光合作用，从而产生葡萄糖供生长。
Variables:
变量：
- Independent variable: amount of light (light vs complete darkness). 自变量：光照量（光照与完全黑暗）。
- Dependent variable: height of the seedling measured in cm. 因变量：幼苗的高度，以厘米为单位测量。
- Control variables: type of seed, amount of soil, pot size, volume of water given each day, room temperature. 控制变量：种子种类、土壤量、花盆大小、每天浇水量、室温。
Method:
方法：
- Fill two identical pots with the same amount of potting compost. 两个相同的花盆装入等量的盆栽堆肥。
- Sprinkle ten cress seeds evenly on the surface of each pot. 在每个花盆表面均匀撒上十粒水芹种子。
- Water both pots with 20 ml of water. 给两个花盆各浇 20 毫升水。
- Label one pot 'Light' and place it on a sunny windowsill. 将一个花盆标记为“光照”，放在阳光充足的窗台上。
- Label the other pot 'Dark' and place it inside a dark cupboard. 将另一个花盆标记为“黑暗”，放在漆黑无光的橱柜里。
- Water each pot with 20 ml of water every morning. 每天早晨给每个花盆浇 20 毫升水。
- After seven days, measure the height of the tallest seedling in each pot using a ruler. Record the results. 七天后，用尺子测量每个花盆中最高的幼苗高度。记录结果。
Results:
结果： See the table in Section 7. 见第7节中的表格。
Analysis and Discussion: The seedlings in the light grew steadily, reaching 6.8 cm by Day 7. The seedlings in the dark grew much more slowly, reaching only 3.3 cm. The data supports the idea that light helps plants make food and grow. One plant in the dark appeared yellow, which could be due to lack of chlorophyll production. There were no anomalous results in this set of data, but the measurement on Day 5 for the dark pot might be slightly less accurate because the seedling was bent.
分析与讨论：光照下的幼苗稳步生长，到第7天达到6.8厘米。黑暗中的幼苗生长缓慢得多，仅达到3.3厘米。数据支持了光帮助植物制造食物和生长的观点。黑暗中的一株植物出现发黄现象，这可能是由于缺乏叶绿素的生成。这组数据中没有出现异常结果，但第5天对黑暗花盆的测量可能稍欠准确，因为那株幼苗有点弯。
Conclusion: In conclusion, the results show that light does affect the growth of cress seedlings. After one week, plants grown in light were almost twice as tall as those grown in darkness. This supports my hypothesis and confirms that light is essential for photosynthesis and healthy plant growth.
结论：总之，结果表明光确实会影响水芹幼苗的生长。一周后，在光照下生长的植物几乎是黑暗中生长植物的两倍高。这支持了我的假设，并证实了光对于光合作用和植物健康生长至关重要。
11. Common Mistakes to Avoid | 常见错误要避免
Many students lose marks by rushing certain sections. A classic mistake is writing a method that is too vague, such as 'Put the plant in the light'. Instead, specify exactly how much light, for how long and where.
很多学生因为匆忙完成某些部分而失分。一个典型错误是方法写得过于含糊，比如“把植物放在光下”。相反，要明确说明多少光、多长时间以及什么地方。
Another common error is confusing variables. Remember, the independent variable is what you choose to change, and the dependent variable is what you measure as a result. Revise this before you start writing.
另一个常见错误是混淆变量。记住，自变量是你选择改变的量，而因变量是你作为结果来测量的量。在动笔之前先复习一下这个。
Some pupils forget to include units in tables and graphs. Without units, your data loses meaning. Always label headings as 'Time (seconds)' or 'Temperature (°C)'.
有些学生忘记在表格和图中加上单位。没有单位，你的数据就失去了意义。始终将表头标为“时间 (秒)”或“温度 (°C)”。
Finally, avoid writing a conclusion that does not refer back to the aim or the hypothesis. Your conclusion must be rooted in the evidence you collected, not on your original expectation.
最后，避免写出一个没有回扣目标或假设的结论。你的结论必须根植于你收集到的证据，而不是你最初的期望。
12. Final Tips for Success | 成功最后小贴士
Before you submit your report, read it through as if you were a scientist picking it up for the first time. Check that every section flows logically and that a stranger could repeat your experiment exactly from your method.
在提交报告之前，假想自己是一位初次读到这份报告的科学家，通读一遍。检查每个部分逻辑上是否连贯，一个陌生人能否根据你的方法严格重复你的实验。
Use diagrams or photos of your setup if your teacher allows it. A labelled drawing of the apparatus can make your method even clearer and shows attention to detail.
如果老师允许，使用设备照片或示意图。一幅带标注的装置图可以使你的方法更加清晰，并显示你对细节的关注。
Finally, ask a friend to look for spelling errors and check your table alignment. Neat presentation makes a strong impression and helps the reader focus on your scientific thinking rather than getting distracted by messy handwriting or typos.
最后，请一位朋友帮你检查拼写错误并核对表格的对齐情况。整洁的呈现会给人留下深刻印象，并帮助读者专注于你的科学思维，而不至于被潦草的字迹或错别字分散注意力。
