IB生物IA有哪些比较新颖的主题想法？

做IB生物IA，首先需要明确自己的选题，那么IB生物IA有哪些比较新颖的主题想法呢？下面考而思惟世为大家分享几个比较不错的题目，希望对你有帮助。

需要注意的是，所有科学课程的IA都源于实验，IB生物IA也不例外，这里讲的“实验”涵盖两种-自己的实验和别人的实验。

大多数学生会选择自己做实验，那就要求从设计，操作，分析数据，完成报告，全部都由自己来。还有一少部分学生选择分析别人的实验。因为其中省略了自己设计和操作的部分，对“别人的实验”要求就会更高，需要学生能够在网上搜集大数据。同时，对“分析数据”要求也更高，至少要有生物统计学的概念。

介于大多数学生都会选择自己做实验，我们今天也只谈如何选一个合适的题目。毕竟，如果选题不好，后面都是会哭的。由于小伙伴们要用英语写好生物IA，因此本次分享均为英文。
