CAMERA/PICTURE HELP!!! PLEASE ANSWER :)?

Ok..so I'm going to the rodeo tonight..and I'm bringing my camera..my dad is coming too..and I'm afraid that he might ask to look through my pictures or videos cuz over the summer..i got in trouble for uploading some videos on youtube and he doesn't want me doing that..so..is there a way that i can somehow upload all my pictures/videos to my computer and save it somewhere..and then delete everything from my camera..and then when i get back..somehow upload them back to my camera?? is that possible??
