What is the Internal Assessment

Your Internal Assessment (IA) is a project that you will have to complete in all your IB classes. The style and grade value depends on the subject. It is a project that you will work on with the guidance of your teacher (or your tutor). The great thing about the internal assessment is that it allows students to be flexible and to further research a topic that they find interesting within the given subject. As good as it sounds, generating IA topic ideas is not always easy and that’s why we decided to help you here with some unique physics IA ideas, just read on!

What Makes a Good Physics IA

A good IA should demonstrate your own interest of the topic. It should show that the student has learned and has been able to apply what they have learned. A good IA does not have to be a very complex and intricate piece of work. A clearly stated and clearly answered research question, consistent structure, and clear personal engagement which demonstrates knowledge will earn the student a good grade.

So let’s jump into what you are here for. Here is a list of 25 possible topics that serve as great physics IA ideas. To keep in mind, in a physics IA, you have two options, laboratory work or an essay, so the topic possibilities are far greater than just the list below.
