学习IB物理的学生可能最头疼的就是IA了吧，IA是IB课程的内部评估，是非常重要的一部分，也占据着很大一部分的分数，想要拿高分，必须要重视IA，而做IA，选题非常关键，在教学大纲的范围内找到最好的IB物理IA主题并不容易。
为了帮助大家更好的应对这部分，今天，留求艺留学为大家总结了多个IB物理IA想法，如果你是来学习更多关于选题的知识，或者你只是因为还有时间而在寻找一个选题思路，那么你来对地方了！
如何选择IB物理IA题目？
1、确定自己感兴趣的领域
问问自己：在最近的一堂物理课上，什么话题激起了自己的兴趣？自己对物理相关概念有什么爱好吗？在空闲时间最喜欢做什么，并且很容易与物理联系起来？
2、选择一个可变的自变量
在这方面，需要有一个重点研究问题，这是将在1500字的限制内探索的问题。要构建一个合理的研究问题，首先需要想出一个容易改变的独立变量。这里的关键点是关于自己感兴趣的话题的易变变量。请记住，选择的变量必须是可测量的。温度、时间、压力和质量都是很好的例子。记住要避免任何不连续的属性，如材料类型。
3、确定一个易于测量的因变量
因变量是在调整自变量时发生变化的量。要确保自己的因变量易于测量。
4、写下自己的研究问题
选择合适的IB物理内部评估题目的最后一步是写下自己的研究问题。然后，阅读问题，确保这个研究是有意义的。
