Includes data/information (e.g. oxygen levels, temperature, amount of vegetation/water, predators, gravity) on 6 imaginary planets - and Earth. Info on Earth is roughly accurate. This info is presented in the form of a table and as a range of graphs (e.g. pie/bar charts). Aim of lesson is to first work out which graphs represent which planet. Children can then decided whether a planet is inhabitable (by comparing it to Earth's data). (Includes brief lesson plan).
