Science Heroes: Digestive System for Kids is an excellent free educational Science app by Yogome. Yogome is a company known for their educational iOS games from subjects from Math and Science to Recycling. Also, their games feature their popular characters known as the Yogotars in fun filled cartoony world.
Science Heroes is more of the same w/ excellent graphics and high replay value as students try to defeat 5 bosses in over 15 levels/missions of fun, while learning about the different areas of the Digestive System (i.e. Mouth, Esphagus, Stomach, etc.).
I highly recommend checking out Science Heroes by clicking here!!!
