5. Prototyping and Building | 原型制作与搭建
Build a quick 'proof-of-concept' model using cheap materials. It doesn't need to look perfect—it just needs to test the core mechanism.
用廉价材料制作一个快速“概念验证”模型。它无需看起来完美——只需要测试核心机制。
Measure twice, cut once. Use jigs or guides to ensure repeatable accuracy, especially for parts that must fit together tightly.
量两次，切一次。使用夹具或导向器确保可重复的精度，尤其是必须紧密配合的部件。
Always prioritise safety: wear goggles when sawing, secure loose clothing, and work under adult supervision when using glue guns or craft knives.
始终将安全放在首位：锯切时佩戴护目镜，固定宽松衣物，并在使用胶枪或美工刀时在成人监督下工作。
Take photos of each build stage. These visuals are invaluable for your design journal and final presentation.
拍摄每个建造阶段的照片。这些视觉资料对你的设计日志和最终展示极具价值。
6. Testing and Data Collection | 测试与数据收集
Design a fair test: change only one variable at a time while keeping all others constant. For example, test wing shape with the same surface area and wind speed.
设计一个公平测试：一次只改变一个变量，其他所有保持不变。例如，在相同表面积和风速下测试机翼形状。
Record measurements in a data table with proper units. Calculate the mean of repeated trials and note any anomalous results.
在数据表中用正确单位记录测量值。计算重复试验的平均值，并记下任何异常结果。
Present results using clear graphs—bar charts for comparisons, line graphs for trends. Add error bars if you have sufficient data.
使用清晰的图表展示结果——比较用条形图，趋势用折线图。如果有足够数据，添加误差线。
If something breaks, document the failure mode. Was it buckling, shearing, or fatigue? A failure analysis demonstrates mature engineering thinking.
如果某物损坏，记录失效模式。是屈曲、剪切还是疲劳？失效分析展示了成熟的工程思维。
7. Iteration and Improvement | 迭代与改进
Based on test data, pinpoint specific weaknesses. Instead of starting over, focus on modifying one component at a time to isolate improvements.
根据测试数据，找出具体弱点。不要重新开始，而是专注于每次修改一个组件以分离改进效果。
Keep a log of each iteration: date, what was changed, why, and the effect. A structured log impresses judges more than a messy collection of ideas.
记录每次迭代：日期、更改内容、原因和效果。结构化的日志比杂乱的想法合集更能打动评委。
Encourage team members to suggest fixes from different angles. A builder's practical insight and a designer's analytical view can spark the best solution.
鼓励团队成员从不同角度提出修复建议。建造者的实用洞察和设计者的分析视角能碰撞出最佳解决方案。
Avoid endless tinkering—set a 'freeze' date for the design so you have enough time left for presentation preparation.
避免无休止的修补——设定一个设计“冻结”日期，这样你就有足够时间准备展示。
8. Teamwork and Communication | 团队合作与沟通
Assign roles early based on individual strengths: project manager, lead designer, fabricator, researcher, and presenter. Rotate tasks if someone feels stuck.
尽早根据个人优势分配角色：项目经理、首席设计师、制造者、研究员和演讲者。如果有人感到困顿，可轮换任务。
Use a shared online document or physical logbook to track progress. Everyone should update it daily to avoid silos.
使用共享在线文档或实体日志来跟踪进度。每个人应每日更新，避免信息孤岛。
Hold a 10-minute stand-up meeting each session. Three questions: What did I accomplish? What will I do next? What obstacles do I face?
每阶段举行一个10分钟的站立会议。三个问题：我完成了什么？接下来我要做什么？我面临什么障碍？
Practise active listening—restate your teammate's idea before critiquing it. This builds trust and reduces conflict under pressure.
练习积极倾听——在批评前重述队友的想法。这能建立信任并减少压力下的冲突。
9. Time Management and Planning | 时间管理与规划
Work backwards from the submission deadline. Mark key milestones: design freeze, prototype complete, testing done, presentation draft.
从提交截止日期倒推。标记关键里程碑：设计冻结、原型完成、测试结束、展示草稿。
Use a Gantt chart or a simple calendar with coloured stickers. Visual timelines help the whole team see the big picture.
使用甘特图或带有彩色贴纸的简单日历。可视化时间线有助于整个团队看到全局。
Always include buffer days—materials might arrive late, tools could break, or someone might be absent. Plan for the unexpected.
始终包含缓冲天数——材料可能迟到、工具可能损坏，或者有人可能缺席。为意外做计划。
End each week with a 'progress vs plan' review. If you are behind, decide whether to simplify a feature or put in extra hours.
每周结束时进行“进度与计划对比”审查。如果落后，决定是简化某个功能还是投入额外时间。
10. Preparing the Presentation and Pitch | 准备展示与演讲
Craft a compelling narrative: identify the problem, show your research, explain your design journey, reveal results, and highlight lessons learned.
打造一个引人入胜的叙述：确定问题、展示研究、解释设计历程、揭示结果并突出经验教训。
Design slides with minimal text—use high-quality photos, diagrams, and short bullet points. A working model demonstration is far more powerful than a description.
设计幻灯片时应尽量减少文字——使用高质量照片、图表和短要点。工作模型演示远比口头描述更有力量。
Rehearse the pitch as a team until everyone knows their part. Time each section; typical presentations are 5 to 10 minutes with Q&A.
团队一起排练演讲，直到每个人都知道自己的部分。为每个部分计时；典型演讲时间为5到10分钟，外加问答。
Anticipate judges' questions: 'Why did you choose this material?', 'How did you ensure safety?', 'What would you improve with more time?' Prepare clear, concise answers.
预判评委的问题：“为什么选择这种材料？”、“如何确保安全？”、“如果有更多时间，你会改进什么？”准备好清晰简明的答案。
11. Day of the Competition: Mindset and Logistics | 竞赛当日：心态与后勤
Pack a checklist: project model, backup components, tools, safety gear, poster, USB with presentation, printed handouts, and chargers.
