In addition to teaching students about water systems content, the MHS curriculum also focuses on building students’ argumentation skills. Within each unit, students are given the opportunity to formulate an argument by appropriating claims, reasoning and evidence. Within each unit, player will collect data about the planet and use their collected data to support their arguments. Throughout the game players will argue about a range of topics from where to set up base camp based on the size of surrounding watersheds to the cause of a flood in an underground bunker based on data about soil profile. The MHS curriculum emphasizes an understanding of water systems knowledge, as well as applying science knowledge in the argumentation tasks.
