How much Inventor training have you had?
Do you know what a STEP file is? If you don't.. A step file is a 3D Neutral CAD file that allows you to export the model from one CAD application and import it into another CAD package. For example the link I provide those files were create in Pro/E/Creo which is another Solid Modeling CAD application.
In Inventor, you would simply select Open and in the open dialog you would change the file type to STEP. However Inventor can also open Pro/E/Creo files and you can just change the file type to match in.

It all depends on what information and file types are in those ZIPPED files they provide in the link that I shared. In the end when you open models from other CAD application the information that comes in is considered a "DUMB SOLID". Which means there's no parametric dimensional values and feature history.
Is there a reason why you can't use Inventor 2017? If you school stuck on Inventor 2016 and you need to be in this event I might suggest your school upgrade/use Inventor 2017 and save you time in using these files.
