As I understand it, according to the Google Maps/Earth Additional Terms of Service you cant't as this would be considered "derivative works of the Content".
"Unless you have received prior written authorization from Google (or, as applicable, from the provider of particular Content), you must not: (a) copy, translate, modify, or make derivative works of the Content or any part thereof"
I actually decided to obtain a written permission for a project years ago and did receive a response. The response in my case was NO but they did reply. Because in your case you will be using the content for educational purposes there may an exception.
However, you may include maps and imagery in reports that was exported from Google Earth application (not sure if this excludes commercial use) but these images have to attributed correctly.
Suppose you use only tools available in Google Earth Pro API to delineate these areas and show the results within the Google Earth framework without altering or modifying the exported image I think this should be acceptable especially if you word the language summarizing the data obtained in this fashion correctly.
