To aid student learning (and teaching) in the Lifecycle of Stars. Involves an interactive Hertszprung Russell diagram which is included in the curriculum for UK Schools at GCSE, A level and also at undergraduate level. Siab is an interactive Hertszprung Russell diagram which plots brightness of stars against their temperature to show the different types of stars and their lifecycle from star formation to star death (this is based on a real published stellar evolution model). It allows the user to interact via looking at different information and reading values of stellar mass, temperature, age etc., as well as fundamentally seeing that the properties of their “model” star change as it ages. Students can plot their own graph and learn names of the stages of stars e.g. main sequence, red giant etc.
