📚 CCEA Year 7 Science: Scientific Report Writing Framework & Model Answers | CCEA 七年级科学：科学报告写作框架与范文
Learning to write a scientific report is a core skill in CCEA Year 7 Science. It helps you think like a real scientist: asking questions, testing ideas, collecting evidence, and explaining your findings clearly. This guide provides a complete framework you can follow for any investigation, along with model answers that show exactly what high-quality work looks like.
学会撰写科学报告是 CCEA 七年级科学的核心技能。它能帮助你像真正的科学家一样思考：提出问题、验证想法、收集证据并清晰地解释你的发现。本指南为你提供了一个适用于任何探究实验的完整写作框架，并附上范文，清晰展示高质量作业的标准。
1. What is a Scientific Report? | 什么是科学报告？
In CCEA Year 7 Science, a scientific report is a structured way of documenting an experiment or investigation. It lets you share what you did, what you observed, and what you learned. Writing a report helps you organise your thinking and communicate scientifically with others.
在 CCEA 七年级科学中，科学报告是记录实验或探究过程的结构化方式。它能让你分享你的操作步骤、观察结果以及所学知识。撰写报告有助于整理你的思路并与他人进行科学交流。
Your teacher will look for clearly labelled sections, accurate data recorded in tables, and logical conclusions backed by evidence. A well-written report can significantly boost your marks in practical assessments and end-of-topic tests.
你的老师会寻找标注清晰的各个部分、记录在表格中的准确数据以及有证据支持的逻辑结论。一份撰写精良的报告能显著提高你在实践评估和单元测试中的分数。
2. The Standard Framework for CCEA Science Reports | CCEA 科学报告的标准框架
Every scientific report you write in Year 7 should follow the same clear structure. The key sections are:
在七年级，你撰写的每份科学报告都应遵循同样清晰的结构。关键部分包括：
Title: A specific heading that names the independent and dependent variables, such as ‘Investigating how the mass of a pendulum bob affects the time for 10 swings’.
标题：一个具体的标题，指明自变量和因变量，例如“探究摆锤质量如何影响摆动10次所需的时间”。
Aim: A short statement starting with ‘To investigate …’ that explains the purpose of the experiment.
目的：以“探究……”开头的简短陈述，解释实验的目的。
Hypothesis: A prediction based on scientific reasons, often written as ‘If … then … because …’.
假设：基于科学理由的预测，通常写作“如果……那么……因为……”。
Materials: A bullet-point list of all equipment, including quantities and sizes.
材料：列出所有用到的设备和耗材的项目符号清单，要注明数量和尺寸。
Method: Numbered, step-by-step instructions that anyone else can follow to repeat your experiment. It should be written in the imperative and include how to keep it a fair test.
方法：编号式的、一步步的说明，确保其他人能够按照它来重复你的实验。应当使用祈使语气，并说明如何保持公平测试。
Results: A clear results table with headings and units, followed by a graph where appropriate. Observations are written in full sentences.
结果：一个带有表头和单位的清晰结果表格，必要时应附有图表。观察结果用完整的句子记录。
Conclusion: A paragraph that states what you found out, whether your hypothesis was supported, and explains the science behind the pattern.
结论：一个段落，陈述你发现了什么、你的假设是否得到支持，并解释模式背后的科学原理。
Evaluation: A reflection on the reliability and accuracy of your data, any anomalies, and suggestions for improving the method.
评价：对数据可靠性和准确性、任何异常值以及改进方法的建议进行反思。
3. How to Write a Strong Aim and Hypothesis | 如何撰写有力的目的与假设
Your aim must tell the reader exactly what relationship you are investigating. Use the format: ‘To investigate how [independent variable] affects [dependent variable].’ For example: ‘To investigate how the number of magnets affects the distance a paper clip jumps.’
你的目的必须准确告诉读者你正在探究的关系。使用格式：“探究 [自变量] 如何影响 [因变量]”。例如：“探究磁铁数量如何影响回形针跳跃的距离”。
A hypothesis should be a clear prediction with a reason. Think ‘If I change this, then I think this will happen, because of a scientific idea.’ For instance: ‘If the number of magnets increases, then the paper clip will jump a longer distance because the magnetic force becomes stronger.’
假设应是一个带有理由的清晰预测。想着“如果我改变这个，那么我认为会发生这个，因为某个科学原理”。例如：“如果磁铁数量增加，那么回形针会跳跃更远的距离，因为磁力变得更强”。
Avoid vague predictions like ‘I think it will change.’ Always link your hypothesis to the science you have learned in class, such as forces, energy, or living processes.
避免模糊的预测，如“我认为它会改变”。始终将你的假设与在课堂上学到的科学知识联系起来，比如力、能量或生命过程。
4. Listing Materials and Crafting a Method | 列出材料并精心撰写方法
A complete materials list allows anyone to set up the experiment. Include all items and their quantities: ‘3 paper clips, 1 bar magnet, ruler (30 cm), 1 metre ruler.’ Do not include safety equipment as a material unless it is part of the measurement.
一份完整的材料清单能让任何人搭建这个实验。应包含所有物品及其数量：“3个回形针、1个条形磁铁、尺子（30 cm）、1个米尺”。除非安全设备是测量的一部分，否则不要将其列为材料。
Your method must be written as numbered instructions in the correct order. Every step should begin with a command word: ‘Measure 20 ml of water using a measuring cylinder. Pour it into the beaker. Record the starting temperature.’ It is good practice to mention repeating measurements to improve reliability.
你的方法必须按正确顺序用编号指令撰写。每一步都应以命令词开头：“用量筒量取20 ml水。将其倒入烧杯中。记录起始温度。” 最好提到重复测量以提高可靠性。
Describe the control variables you keep the same to ensure a fair test. For example: ‘Use the same volume of water for each trial. Keep the starting temperature the same.’
描述你为保持公平测试而保持不变的对照变量。例如：“每次试验使用相同体积的水。保持起始温度相同。”
5. Recording Results: Tables and Observations | 记录结果：表格与观察
Results should be presented in a neat table with clear headings and units. Draw the table before you start the experiment so you can fill it in as you go.
结果应呈现在一个整齐的表格中，表头清晰并带单位。在开始实验前就画好表格，这样你就可以边做边填入数据。
Every column heading must state what is being measured and the unit, for example ‘Height of plant (cm)’. Include a row for the mean or average if you have repeats. An example table is shown below:
每个列标题都必须说明测量的内容和单位，例如“植株高度 (cm)”。如果你进行了重复实验，要包含一行平均值。下表展示了一个示例：
| Type of surface | Distance toy car travelled, Trial 1 (cm) | Trial 2 (cm) | Trial 3 (cm) | Mean distance (cm) |
|---|---|---|---|---|
| Smooth wood | 82 | 79 | 85 | 82 |
| Carpet | 34 | 37 | 31 | 34 |
| Sandpaper | 15 | 12 | 18 | 15 |
Qualitative observations, like colour change or fizzing, should be written in full sentences below the table. Example: ‘When the acid was added, the mixture bubbled rapidly and the blue litmus turned red.’
定性观察，如颜色变化或冒泡，应写在表格下方的完整句子中。示例：“加入酸后，混合物迅速冒泡，蓝色石蕊试纸变为红色。”
6. Analysing Data and Drawing Conclusions | 分析数据并得出结论
Start your conclusion by answering the aim directly. ‘In this experiment, the smooth wood surface allowed the toy car to travel the furthest distance with a mean of 82 cm, while sandpaper gave the shortest distance of 15 cm.’
以直接回答目的来开启你的结论。“在本实验中，光滑木面使玩具车行驶了最远的平均距离 82 cm，而砂纸面行驶了最短的距离 15 cm。”
Next, state whether your hypothesis was supported or not. ‘This supports the hypothesis that smoother surfaces reduce friction and allow the car to travel further.’ Never say you ‘proved’ something; use ‘supported’ or ‘not supported’.
下一步，陈述你的假设是否得到支持。“这支持了假设，即更光滑的表面减少摩擦并使小车行驶得更远。” 永远不要说“证明”了什么；要使用“支持”或“不支持”。
Explain the pattern using scientific knowledge. ‘The smooth wood has less friction because its surface is flatter, so less energy is transferred as heat, allowing the car to keep moving.’ Always link back to the data as evidence.
使用科学知识解释这一模式。“光滑木面的摩擦力较小，因为其表面更平整，因此转化为热能的能量更少，使小车得以继续运动。” 始终将数据作为证据予以引用。
7. Evaluating Your Experiment: Strengths and Improvements | 评价实验：优点与改进
Evaluation shows you can think critically about your work. Discuss how reliable your results were. ‘We repeated the test three times for each surface and found the readings were very close, so the results are reliable.’
评价表明你能够批判性地思考自己的工作。讨论你的结果可靠性。“我们对每个表面重复测试了三次，发现读数非常接近，因此结果是可靠的。”
Identify any anomalies and explain why they might have happened. ‘One trial on sandpaper gave a value of 25 cm, which is higher than the rest. This could be because the car was pushed slightly harder by accident.’ Do not hide unusual results.
