IB课程的EE该怎么选科

选HL科目是默认常规

EE是一个比较接近于你大学写Essay时候的INDEPENDENT RESEARCH，需要学生有Personal Engagement，但要根据自己能力，第一年不能拿6、7分的科目慎选，EE涉及的选科内容大于普通IA，如果不擅长结果半途换题实在不可。

最好选择你最喜欢的学科

写EE的过程较为漫长，兴趣是孩子最好的老师，需要独立思考且深入研究，要有思路和实践方法。

EE灵感最好取自生活细节

不同于IA只是单纯的研究问题，EE是需要有学术层次的思考，IB就是想拿EE来引导大家不论是自然还是人文艺术，值得深究的是生活中的细节。研究课题要有可行性，需要大量数据材料的辅助。

IBO官网上有整理非常多的各科EE范文，很多孩子们可能不知道，或者没有时间去搜索，这次就给大家下载好整理好啦，家里有需要的孩子们可以存一份哦～

Figure 2：Acetic Anhydride

As have discussed in the introduction,acetic anhydride exhibits numerous hazardous effects and

can be used to produce heroin.Additionally,since it is a Category IVsubstance-which refers to a group ofstrictly regulated chemicals that can be used to produce illicit narcotics in Thailand-the compound is not an ideal candidate for a green synthesis and thus prompted me to look for possible replacements. Observing that compounds must contain the acetyl group,I found two possible acetic anhydride replacements:acetyl chloride(Figure 3)and acetic acid (Figure 4). The acetyl groups are highlighted in red.

However, after further investigation,I found out that acetyl chloride like acetic anhydride,is also a Category IV substance.Being category IV substances they are illegal for normal uses in Thailand(Chaninat).While quantitative conclusions of these two substances could not be drawn.
