EE是IB課程的三大核心課程之一，要求學(xué)生選擇一門主題進行研究總結(jié)，相信有不少學(xué)生會選擇IB化學(xué)。做EE，選題非常關(guān)鍵，一個優(yōu)秀的題目是成功的一半，所以，今天為大家分享一下IB化學(xué)EE選題技巧，并附上30+IB化學(xué)EE高分題目，希望對大家有幫助。

IB化學(xué)EE要求學(xué)生們研究我們環(huán)境組成的特定領(lǐng)域，在更廣泛的研究標(biāo)準(zhǔn)范圍內(nèi)，論文應(yīng)該突出一個特定的化學(xué)方面。研究的結(jié)果應(yīng)該是一篇有邏輯、有條理的文章，有效地解決某個主題或研究問題，并得出一個具體的、理想的個人結(jié)論。

IB化學(xué)EE選題技巧：

1、選擇一個專注于化學(xué)的話題

IB化學(xué)EE的重點應(yīng)該是化學(xué)，而不是其他學(xué)科，化學(xué)是對物質(zhì)的組成、分類和變化的研究。

因此，一篇很長的化學(xué)論文應(yīng)該包括化學(xué)原理和理論，并強調(diào)化學(xué)的核心特征，即研究物質(zhì)及其轉(zhuǎn)化。

2、選擇可以提供一個基于化學(xué)方法的主題

雖然相同的評估標(biāo)準(zhǔn)適用于所有的延伸論文，但化學(xué)延伸論文的主題必須提供不同的化學(xué)方法。雖然可以從幾個角度來處理一個話題，但必須從化學(xué)的角度來看待一切。

例如，如果注冊為化學(xué)擴展論文，生物化學(xué)擴展論文將根據(jù)其化學(xué)內(nèi)容進行評估，而不是生物內(nèi)容。

3、注意評估標(biāo)準(zhǔn)

主題的廣度和伴隨的研究應(yīng)該考慮到所有的標(biāo)準(zhǔn)。一個優(yōu)秀的主題是一個單一的研究問題的重點，并可能在字?jǐn)?shù)限制內(nèi)充分解決。也許最重要的部分是你對問題進行深入分析的能力。

廣泛或復(fù)雜的調(diào)查主題(如調(diào)查水污染引起的健康問題、癌癥治療的化療或使用光譜學(xué)進行化學(xué)分析)不允許討論對立的觀點和理論或在字?jǐn)?shù)限制內(nèi)進行深入的個人分析。

4、避免引發(fā)安全問題的話題

出于安全考慮，有些題目可能不適合做EE。例如，不應(yīng)該使用有毒或有害的化學(xué)物質(zhì)、致癌化合物或放射性物質(zhì)進行實驗，除非有合適的安全設(shè)備和合格的監(jiān)管人員。

5、避免選擇那些已經(jīng)在教科書中記錄了結(jié)果的話題

其他主題可能不合適，因為結(jié)果在標(biāo)準(zhǔn)教科書中有很好的記錄，學(xué)生可能無法證明個人參與。例如:研究堿金屬與水的相互作用，這在以前的課程中已經(jīng)介紹過。

然而，在確定一個主題是否合適時，必須小心謹(jǐn)慎；例如，對碳的同素異形體的研究在過去可能被認(rèn)為是微不足道的，但現(xiàn)在不再是這樣了。
