The other suggestions here are great. Just describe the facts to people about what goes on there, how the animals are treated, their quality of life. When I did a school project on dairy farming, I concluded by saying how the "mother cows milk that was meant for their babies has been stolen so that it can be given to you" so maybe you could do something like that but in regards to fur farming, like, "the animals need their fur more than you do," or something. There's a reason that those particular animals were born with fur and humans weren't.
Also in terms of videos and pictures, I think pictures would be toned down a bit more than videos because you can't hear the noises the animals make as they're tortured. But wouldn't' you want people to see to as full extent as possible as to what the animals have to go through? I'm in year 9 and as well as doing one on dairy farming, I've also done a school project on animal testing, which included me attaching some footage found online of animal testing. My teacher said she found it very disturbing and hard to watch and now makes an effort to buy products that aren't tested on animals! AND she even wants me to present it to the rest of my class! I think people in year 11 would be able to watch them (since people in my grade are), so I think you definitely should put videos in, and if not, at least pictures - but overall it's your decision. Good luck
