This PowerPoint presentation is intended to show students the pitfalls of using Google Translate and other online translation tools for their homework. It contains links to YouTube videos. It also contains a Google Translated version of Katy Perry's &'Roar&';. One video contains some slight bad language, so will need to be removed for KS3 students. Obviously, use your professional judgement about which groups to show this one too! The rest is suitable for everybody. The presentation also deals with alternatives to online translation tools.
