I am a teacher and also a volunteering firefighter. I often go to accidents and give first aid to the victims. Not beeing afraid of giving first aid is essential - that is why I teach first aid during my classes when I've got time. I prepared this worksheet to join fun & learning. The British Heart Fundation came up with a video with Vinnie Jones. It's a funny way to encourage the practise of performing CPR. The language is quite difficult so I do it with more advanced students. Hope it'll be useful for you.
