About this app
Reservoir Crabs takes all the difficulty out of running an animal experiment by using augmented reality fiddler crabs. With crabs that behave the “right” way each time and are immune to stress, students can focus on improving their understanding of experimental design and behavioural observations. Each crab has real measurements and behaviours which allow players to perform statistical analyses. This game replaces animal behaviour practicals and is best used in a class where individuals work in groups. It can also be used to teach students concepts surrounding animal behaviour. The augmented reality tags can be downloaded from the Arludo website here: https://arludo.com/game/reservoir-crabs
