Science Heroes is an excellent mobile (Android/iOS) app for helping kids learn about the Digestive system in a fun game. This game designed for kids 5-8 focuses on the five phases of digestion (i.e. mouth, esophagus, stomach, etc.) The way this works is through a fun shooter-style game that has kids blasting their way through digestive system while learning different terms and concepts to complete 15 different missions. At the end of the mission is a quiz which educators/parents can access through the parent dashboard to assess their student/child's progress.
