Examples of posters realized by groups of students using the "Consensus Placemat" strategy. Students produced posters of the imaginary world/environment (A, B) by drawing a map and a list of characteristics (e.g. temperature, day length, water availability, gravity, atmosphere composition, mountains, vegetation) of the imaginary world/environment. Posters were hung in the classroom for the gallery tour. A. The "Wild World" planet is characterized by mountains (covering the 75% of planet), rivers and active volcanoes. The climate is temperate. B. The "SEAM" planet has low gravity and it is characterized by two large islands with almost opposite environmental characteristics. The "Cold Island" with ice desert, tundra and taiga; the "Warm Island" with mountains and sandy dunes, covered by Mediterranean macchia-grassland.
