The first step to passing a biology internal assessment assignment is to choose the right topic. But where
do you even begin when you begin thinking and immediately go completely blank and lost for words?
Ideas don't just come to writers out of nowhere. That explains why selecting the ideal biological IA
topics to cover can be difficult for even the brightest students with IBDP Biology Past Paper.
Prior to providing you with some Biology IA subjects for your Higher Level (HL) class assignment, let's
first make sure you are aware of the IB Programme, its goals as programme, and what is expected of
IB IA Programme: What Is It?

In another words:
● Do you have the necessary time, resources, and tools to begin and finish the assignment?
● Are you able to specify your variables and give a pertinent hypothesis?
Look through Reliable Sources for Topics

Is the Topic Safe and Moral?
It's crucial to remember that IB has rigorous policies in place to safeguard animals from harm and
The law stipulates that you must obtain participants' agreement before using them in an experiment.
This remark makes it apparent that the IB Biology Internal Assessment is a project that involves
Therefore, the subject you select should be secure, moral, and environmentally responsible.
