r(e)flect is a tangible curriculum kit for students age 10-15 to reflect on energy behaviour and make better informed choices about energy use. Along with web-based material, the kit includes a minicomputer, smart plugs (sensors), and an electricity visualization tool especially designed to be used in the classroom to conduct experiments and measurements, perform project work in product development, and increase the understanding of the kWh concept. The curriculum is closely connected to the new Swedish National curriculum and supplies the teachers with appropriate support for assessment of different skills. The project was initiated in 2011 and a first version of the curriculum was tested and evaluated with students and teachers. The feedback from this trial influenced the second iteration of the kit. The new version will be tested in at least 20 schools during the spring of 2014 and this second phase will continue until 2015. The physical r(e)flect material can be borrowed by teachers free of charge, and the web-based platform is open and accessible to anyone.
