This is a very good teachable moment for your daughter; encourage her as such.
... the SD card is EXTREMELY vulnerable to corruption if the machine is active and the power is suddenly removed... the reason is that there is data in memory buffers that has not been written out to disk, including mapping and meta data information... so, removing the power prevents the SD card from being updated and leaving the SD card in a corrupted state from which there is usually no remedy. Mounting the SD card in another linux machine (like the mint linux on my HP noteboot) and running fsck ... sometimes works, but usually NOT.
Basically, your daughter needs to understand what she did, and then she needs to go through the process of building another SD card from download images. She won't pull the plug on that thing again, I bet you..
