Some of the presentations contain links to videos on YouTube (they are not my property so I couldn't upload them here). If you can't get YouTube in your school consider ripping the videos onto your hard-drive to use, there are several pieces of software, or websites, where this can be done free of charge.
Please feel free to adapt the resources as you see fit, they have all being uploaded in editable formats. If you find the resources useful please comment on TES and share them with other teachers.
