Windows can not open the Mac version of Easy Draw files. Unless your daughter is using the Windows version and the school already has the Windows version running on their system, she will be unable to open the files using their computer.
It's possible that you can export the Easy Draw drawings into a format that would be openable on a Windows computer, but that would depend HEAVILY on what drawing software (if any) the Windows computer has on board.
Probably best to "print" the drawings as PDFs and open them on the Windows computer using Adobe Reader. You can't edit them there, but you can view them perfectly well.
