EE是IB课程的三大核心课程之一，要求学生选择一门主题进行研究总结，相信有不少学生会选择IB化学。做EE，选题非常关键，一个优秀的题目是成功的一半，所以，今天为大家分享一下IB化学EE选题技巧，并附上30+IB化学EE高分题目，希望对大家有帮助。
IB化学EE要求学生们研究我们环境组成的特定领域，在更广泛的研究标准范围内，论文应该突出一个特定的化学方面。研究的结果应该是一篇有逻辑、有条理的文章，有效地解决某个主题或研究问题，并得出一个具体的、理想的个人结论。
IB化学EE选题技巧：
1、选择一个专注于化学的话题
IB化学EE的重点应该是化学，而不是其他学科，化学是对物质的组成、分类和变化的研究。
因此，一篇很长的化学论文应该包括化学原理和理论，并强调化学的核心特征，即研究物质及其转化。
2、选择可以提供一个基于化学方法的主题
虽然相同的评估标准适用于所有的延伸论文，但化学延伸论文的主题必须提供不同的化学方法。虽然可以从几个角度来处理一个话题，但必须从化学的角度来看待一切。
例如，如果注册为化学扩展论文，生物化学扩展论文将根据其化学内容进行评估，而不是生物内容。
3、注意评估标准
主题的广度和伴随的研究应该考虑到所有的标准。一个优秀的主题是一个单一的研究问题的重点，并可能在字数限制内充分解决。也许最重要的部分是你对问题进行深入分析的能力。
广泛或复杂的调查主题(如调查水污染引起的健康问题、癌症治疗的化疗或使用光谱学进行化学分析)不允许讨论对立的观点和理论或在字数限制内进行深入的个人分析。
4、避免引发安全问题的话题
出于安全考虑，有些题目可能不适合做EE。例如，不应该使用有毒或有害的化学物质、致癌化合物或放射性物质进行实验，除非有合适的安全设备和合格的监管人员。
5、避免选择那些已经在教科书中记录了结果的话题
其他主题可能不合适，因为结果在标准教科书中有很好的记录，学生可能无法证明个人参与。例如:研究碱金属与水的相互作用，这在以前的课程中已经介绍过。
然而，在确定一个主题是否合适时，必须小心谨慎；例如，对碳的同素异形体的研究在过去可能被认为是微不足道的，但现在不再是这样了。
