Dig. Forensics. Practice projects??

Hello, all. I am close to graduating with an IT/cybersecurity degree. This semester, I'm taking the only class that has actually peaked my interest since I've been at university, which is digital forensics. We've done a few labs in class that I've done ok on, but I want to try some stuff on my own. Did anyone know of any free resources that can allow me to get some df practice in on a Linux OS?
