Bullet journals are a quick and creative way to track your actions, habbits and thoughts over time. This KS2 & KS3 bullet journal colouring exercise, encourages students to reflect on how sustainable they are in their day -to day habits. They are asked to colour in each vertical ’ strand’ of the rainbow to show whether they have completed any of the environmentally helpful actions on a daily basis, over a 25 day period. The students could do this just as a starter at the beginning of each each geography lesson, or consecutively as an ongoing homework task. The aim of the bullet journal is to develop student’s accountability as global citizens by teaching them to lead sustainable lives. This lesson/ worksheet would make a perfect addition to a SOW on sustainability or Earth Day theme. There is also a set of de-brief questions provided for students to answer in class, or as a discussion framework, for them to reflect on how well they have done after the 25 day period. These could be blown up onto A3 and made into colourful displays for the classrooms also.
