Quest Lost on an Island differentiated group activ

Project based learning. This project is levelled (and sub levelled) from a 4.5 - 6.75. it also assessed PLTs. The task is for students to answer 'THE BIG QUESTION&' - How will you ALL survive? I divided students in to groups of ability. Each group were asked to take on a role and in this role they were responsible for taking on one of the tasks in the project. Differentiated throughout. Tasks to enhance learning (cut up and dropped in to more able groups to develop learning and questioning). Please rate as would be useful for feedback so further work can be created like this.
