📚 How to Write a Scientific Report: Year 7 AQA Framework and Model Answer | 如何撰写科学报告：Year 7 AQA 框架与范文
In Year 7 AQA Science, you will often be asked to write up experiments using a clear structure. Knowing how to present your method, results and conclusions is just as important as doing the practical work. This guide walks you through the standard framework and provides a complete model answer so you can see exactly what a good report looks like.
在 Year 7 AQA 科学课程中，你经常需要按照清晰的结构撰写实验报告。如何展示你的方法、结果和结论与动手做实验同等重要。本指南将带你了解标准的报告框架，并提供一篇完整的范文，让你清楚看到一份优秀报告的样子。
1. The Basic Report Framework | 基础报告框架
Every formal science report for Year 7 should follow the same headings. This makes it easy for your teacher to find information and for you to earn top marks for communication. The standard sections are: Title, Aim, Hypothesis, Equipment, Method, Results, Analysis, Conclusion and Evaluation.
每一份 Year 7 的正式科学报告都应遵循相同的标题结构。这样老师可以轻松找到信息，而你也更容易在表达方面拿到高分。标准部分包括：标题、目的、假设、器材、方法、结果、分析、结论和评价。
A good report always starts with a sharp title that clearly states what you investigated. After that, the aim tells the reader the question you are trying to answer. Some teachers also ask for a hypothesis, which is your scientific prediction before starting the experiment.
一份好的报告总是以一个明确说明研究内容的清晰标题开头。接下来，“目的”告诉读者你要回答的问题。有些老师还要求写出“假设”，也就是你在实验开始前的科学预测。
You must list all equipment in bullet points, making sure to include sizes and quantities where needed. Then the method is written in numbered steps, using the past passive voice as if you have already done the experiment. This trains you to write objectively, just like real scientists do.
你必须用项目符号列出所有器材，必要时注明规格和数量。然后“方法”用编号步骤写成过去时被动语态，好像你已经完成了实验。这可以训练你像真正的科学家一样客观地写作。
2. Variables and Fair Testing | 变量与公平测试
In Year 7 you learn about three types of variables: independent (the one you change), dependent (the one you measure) and control variables (the ones you keep the same). Identifying these clearly in your report shows you understand how to design a fair test.
在 Year 7 你会学到三种变量：自变量（你改变的）、因变量（你测量的）和控制变量（你保持不变的）。在报告中清楚指出这些变量，表明你懂得如何设计一个公平测试。
For example, if you are testing how the length of a pendulum affects its swing time, the independent variable is pendulum length, the dependent variable is the time for one swing, and control variables include the mass of the bob, the angle of release and the type of string.
例如，如果你在研究摆长如何影响摆动时间，自变量是摆长，因变量是摆动一次的时间，控制变量包括摆锤质量、释放角度和绳子类型。
Always write this section early on, right after your aim or as part of your planning. It proves you have thought carefully about making your results reliable.
一定要在报告的前半部分写明这些内容，紧接在“目的”之后或作为计划的一部分。这证明你已经认真思考过如何让结果可靠。
3. Writing a Strong Aim and Hypothesis | 写出有力的目的与假设
The aim is a single sentence that begins 'To investigate...' or 'To find out...'. It must link the independent and dependent variables. A good aim for a cooling experiment might be: 'To investigate how the colour of a container affects the rate of heat loss from hot water.'
目的是一句以“研究……”或“查明……”开头的单句话。它必须把自变量和因变量联系起来。一个冷却实验的好目的可以是：“研究容器颜色如何影响热水散热速率。”
The hypothesis uses scientific knowledge to predict what will happen and why. For instance: 'The black container will lose heat the fastest because dark surfaces are better emitters of thermal radiation than shiny or light surfaces.'
假设运用科学知识预测会发生什么及其原因。例如：“黑色容器散热最快，因为深色表面比光亮或浅色表面是更好的热辐射发射体。”
4. Equipment List with Precision | 精确的物品清单
ment list must be bullet-pointed and should specify details that matter. Do not just write 'beaker'. Write '250 cm³ glass beaker' or 'five test tubes, 15 mm × 150 mm'. This habit shows you are learning to think about accuracy.
器材清单必须使用项目符号，并注明重要的细节。不要只写“烧杯”。而要写“250 cm³ 玻璃烧杯”或“五支试管，15 mm × 150 mm”。这个习惯表明你正在学会考虑准确性。
Include measuring instruments and their ranges or resolutions if relevant, for example 'thermometer, –10 °C to 110 °C, ±0.5 °C'. This helps anyone who wants to repeat your investigation.
需要时，应列出测量仪器及其量程或分辨率，例如“温度计，–10 °C 到 110 °C，±0.5 °C”。这有助于任何想重复你实验的人。
5. Writing a Reproducible Method | 撰写可复制的方法
The method is written as a series of numbered steps. Each step starts with a past participle verb like 'Measured', 'Poured', 'Heated', 'Recorded'. Use the passive voice to say what was done, not what you did. This means you never write 'I measured'. Instead you write 'The length of the spring was measured using a metre ruler.'
方法写成一系列编号步骤。每一步用一个过去分词动词开头，如“测量了”“倒入”“加热”“记录”。使用被动语态描述做了什么，而不是你做了什么。这意味着你决不要写“我测量了”。而是写“弹簧长度用米尺测量。”
This style might feel strange at first, but it is the standard way scientists report procedures. A well-written method means another person could follow your steps and get the same results. That is why you include every important detail: masses, volumes, times, temperatures and how you controlled variables.
这种风格起初可能会觉得奇怪，但这是科学家报告程序的标准方式。写得好的方法意味着别人可以按照你的步骤得到相同的结果。这就是为什么你要包括所有重要细节：质量、体积、时间、温度以及你是如何控制变量的。
6. Recording and Presenting Results | 记录与呈现结果
Results are usually shown in a table first, then in a graph. Draw your table with a ruler pencil, with clear headings and units in brackets, like 'Time (s)' or 'Temperature (°C)'. Never write units inside the data cells. A table must have a title, e.g. 'Table 1: Temperature change over time for different container colours'.
结果通常先用表格展示，再用图表呈现。用铅笔和尺子画表格，表头清晰并在括号中标出单位，如“时间 (s)”或“温度 (°C)”。绝不要在数据单元格内写单位。表格必须有标题，例如“表1：不同容器颜色随时间的温度变化”。
For graphs, put the independent variable on the x-axis and the dependent variable on the y-axis. Label axes with both the quantity and the unit. Use a sensible scale, plot points with small neat crosses, and draw a line of best fit if appropriate.
对于图表，将自变量放在 x 轴，因变量放在 y 轴。用物理量和单位标注坐标轴。使用合理的刻度，用小而整洁的叉号描点，如果合适，画一条最佳拟合线。
7. Data Analysis and Patterns | 数据分析与规律
In the analysis section, you describe what your results show. Use comparative language like 'faster than', 'increased steadily', 'reached a maximum' or 'decreased at a decreasing rate'. Point out the relationship between the independent and dependent variables.
在分析部分，你描述结果说明了什么。使用比较性语言，如“比……快”“稳定增加”“达到最大值”或“以递减的速度减少”。指出自变量和因变量之间的关系。
If you notice any outliers (results that do not fit the pattern), mention them and suggest reasons, such as 'The reading at 120 s was unusually low, possibly because the thermometer was removed briefly.' This shows deeper scientific thinking.
如果你发现任何异常值（不符合规律的结果），要提到它们并说明可能的原因，例如“120 秒时的读数异常低，可能是因为温度计被短暂地拿出来了。”这体现了更深入的科学思维。
8. Drawing a Valid Conclusion | 得出有效的结论
The conclusion must answer the aim. State clearly what happened and whether the results support your hypothesis. You can phrase it like 'The results show that the black container cooled the fastest, losing 15 °C in 10 minutes, while the silver container lost only 7 °C. This supports the hypothesis that dark surfaces emit heat more quickly.'
结论必须回答研究目的。清楚地陈述发生了什么，以及结果是否支持你的假设。可以这样表述：“结果表明黑色容器冷却最快，10 分钟内下降了 15 °C，而银色容器只下降了 7 °C。这支持了深色表面更快散热的假设。”
Do not make your conclusion too long. A couple of sentences are enough, but they must refer to specific data. Never say 'My hypothesis was right' without explaining how the data prove it.
不要把结论写得太长。一两句话就够了，但一定要引用具体数据。绝不能只说“我的假设是对的”，而不解释数据如何证明它。
9. Evaluating the Experiment | 评价实验
Evaluation is where you think critically about your method. Identify at least two sources of error or limitations. For example, 'The starting temperature was not exactly the same for all trials because hot water was poured quickly from a kettle. This could have made the results less reliable.'
评价是你要批判性地思考你的方法。指出至少两个误差来源或局限性。例如：“由于热水是从水壶中快速倒出的，所有试验的起始温度并不完全相同。这可能使结果的可靠性降低。”
For each limitation, suggest a realistic improvement. 'To improve, we could use a thermostatically controlled water bath to ensure every trial starts at precisely 85 °C.' This shows you are thinking like a real scientist who wants to refine an investigation.
对每个局限性，提出一个切合实际的改进办法。“为了改进，我们可以使用恒温水浴，确保每次试验都精确地从 85 °C 开始。”这表明你像真正的科学家一样思考，想要完善实验。
10. Risk Assessment and Safety | 风险评估与安全
In many Year 7 write-ups, you must include a short safety note. List any hazards (e.g. hot water, glass equipment, Bunsen burner) and the precautions you took. Use a simple table or two sentences: 'Care was taken when handling hot beakers; heatproof gloves were worn. Long hair was tied back when the Bunsen burner was used.'
在许多 Year 7 的实验报告中，你必须包含一个简短的安全说明。列出所有危险（如热水、玻璃器材、本生灯）以及你采取的预防措施。用一个简单的表格或两句话：“处理热烧杯时格外小心；佩戴了防热手套。使用本生灯时将长发束起。”
This shows you can work responsibly in a laboratory. Even if nothing went wrong, mentioning safety is good practice and often required to reach the higher mark bands.
这证明你可以在实验室中负责任地工作。即使一切顺利，提及安全也是一种良好习惯，通常是获得较高分数的要求。
11. Complete Model Answer – Bouncing Ball Experiment | 完整范文 —— 弹跳球实验
The following model answer shows you how all the sections fit together. The investigation question was: 'How does the drop height of a rubber ball affect the height of its first bounce?'
以下范文向你展示所有部分如何组合在一起。研究问题是：“橡胶球的落球高度如何影响其首次弹跳高度？”
Title: Investigating the relationship between drop height and bounce height of a rubber ball.
Aim: To investigate how the drop height of a rubber ball affects the height of its first bounce.
Hypothesis: The higher the drop height, the higher the bounce height, because the ball gains more gravitational potential energy which is converted into a greater amount of kinetic energy at impact, resulting in a larger upward rebound.
标题： 研究橡胶球落球高度与弹跳高度之间的关系。
目的： 研究橡胶球的落球高度如何影响其首次弹跳高度。
假设： 落球高度越高，弹跳高度越高，因为球获得更多的重力势能，在撞击时转化为更大的动能，从而导致更大的向上反弹。
Variables: Independent: drop height (cm). Dependent: bounce height (cm). Control: same ball, same floor surface, ball released without pushing, same measuring method.
Equipment: • 1 rubber ball (diameter 4 cm) • metre ruler (±0.1 cm) • clamp stand • flat tiled floor • sticky tape • eye protection.
变量： 自变量：落球高度 (cm)。因变量：弹跳高度 (cm)。控制变量：同一球体、相同地面、释放时无推力、相同测量方法。
器材： • 1 个橡胶球（直径 4 cm） • 米尺（±0.1 cm） • 铁架台 • 平整瓷砖地面 • 胶带 • 护目镜。
Method: 1. A metre ruler was attached vertically to a clamp stand so that the zero mark touched the floor. 2. The rubber ball was dropped from a height of 20 cm, measured from the bottom of the ball to the floor. 3. The height of the first bounce was recorded by observing the bottom of the ball against the ruler. 4. Steps 2 and 3 were repeated twice more and a mean bounce height was calculated. 5. The procedure was repeated for drop heights of 40, 60, 80 and 100 cm.
方法： 1. 将米尺垂直固定在铁架台上，使零刻度接触地面。2. 从底部到地面测量，将橡胶球从 20 cm 高度释放。3. 通过观察球底部对准米尺的位置，记录首次弹跳高度。4. 步骤 2 和 3 再重复两次，计算平均弹跳高度。5. 对 40、60、80 和 100 cm 的落球高度重复上述过程。
Results table:
| Drop height (cm) | Bounce 1 (cm) | Bounce 2 (cm) | Bounce 3 (cm) | Mean bounce (cm) |
|---|---|---|---|---|
| 20 | 11 | 12 | 11 | 11.3 |
| 40 | 22 | 21 | 23 | 22.0 |
| 60 | 35 | 34 | 33 | 34.0 |
| 80 | 45 | 46 | 44 | 45.0 |
| 100 | 56 | 55 | 57 | 56.0 |
Analysis: As the drop height increased from 20 cm to 100 cm, the mean bounce height increased steadily from 11.3 cm to 56.0 cm. The relationship appears linear: for every 20 cm increase in drop height, the bounce height increased by roughly 11 cm. All readings were consistent, with no obvious outliers.
分析： 随着落球高度从 20 cm 增加到 100 cm，平均弹跳高度从 11.3 cm 稳定地增加到 56.0 cm。二者关系看起来是线性的：落球高度每增加 20 cm，弹跳高度大约增加 11 cm。所有读数一致，没有明显的异常值。
Conclusion: The results support the hypothesis. A higher drop height produced a higher bounce height because the ball stored more energy. The data show a near-direct proportion, with the bounce height being approximately 55–57 % of the drop height across all trials.
结论： 结果支持假设。落球高度越高，弹跳高度越高，因为球储存了更多能量。数据显示接近正比关系，在所有试验中，弹跳高度大约是落球高度的 55–57 %。
Evaluation: One limitation was parallax error when reading the bounce height from the metre ruler. To improve, a slow-motion video camera could record the bounce and a still frame could be analysed with a ruler on screen. Another limitation was that the ball was released by hand, which may have given it a slight push on some trials. An electromagnet release mechanism would eliminate this error.
评价： 一个局限是读取米尺上弹跳高度时的视差误差。为了改进，可以用慢动作摄像机记录弹跳过程，并在屏幕上用尺子分析静止画面。另一个局限是手动释放球体，可能在某些试验中给了它轻微的推力。电磁铁释放装置将消除这种误差。
Safety: Eye protection was worn. The area was kept clear of bags and stools to prevent tripping.
安全： 佩戴了护目镜。清理区域内的书包和凳子，防止绊倒。
12. Top Tips for High Marks | 拿高分的顶级建议
Always check that your independent and dependent variables appear in your table headings and graph axes. Use a sharp pencil for all drawings and graphs. When calculating means, ignore anomalous results and state that you have done so. Never forget units – they are just as important as the numbers.
务必检查自变量和因变量是否出现在表格表头和图表坐标轴上。所有绘图和图表都要用削尖的铅笔。在计算平均值时，忽略异常结果并说明你已这样做。绝不要忘记单位——它们和数字一样重要。
Before you finish, read your report aloud to catch missing words or unclear steps. A well-organized report with clear scientific thinking will always stand out. Use this framework for every practical write-up in Year 7, and you will build excellent skills for Key Stage 4 and beyond.
在完成之前，大声朗读你的报告，找出缺漏的词语或不清晰的步骤。条理清晰、科学思维明确的报告总是能脱颖而出。在 Year 7 的每次实验报告中使用这个框架，你将为 Key Stage 4 及以后的学习培养出色的技能。
