In this video, we will see how to discuss possible extensions to your investigation.
We will talk about how you can do smaller changes or larger changes to extend your work.
Extensions are marked under the evaluation criterion.
Let's see a smaller and a larger change in the example IA.
I begin the extension section with a short introduction.
Here again, you can use different formats.
As you can see, I prefer using the table for clarity.
Let's see the first extension.
I start with the research question.
As you can see, here I only changed the independent variable from liquid height to density and
left the dependent variable the same.
Some of the control variables have changed, some remain the same.
Let's see the second extension.
Here again, I start with the research question, but this time I change both the independent
and dependent variables.
Some control variables change, some remain the same.
There are many different ways that you can write your extension section.
The key is to mention one or two ideas about what you could investigate next.
This completes step seven, action five.
Now you know how to discuss possible extensions to your investigation.
In the next video, we will briefly discuss how to reference your sources.
