Children often perceive abstract concepts such as chemistry as difficult, and teachers struggle to convey content knowledge in these subjects. In this pictorial, we address the need to promote the interest for chemistry in children by developing a multi-layered Augmented Reality serious game that uses storytelling, character design and game mechanics to connect and engage young audiences with chemistry: the Periodic Fable an Augmented Journey. Our contribution relies on the design and development of the system to convey content knowledge about the Periodic Table while fostering the children's interest and challenging their possible daunting perception of the domain. After designing and implementing the game, we conducted an exploratory study using a mixed-method approach engaging 21 young participants from a public school to assess the learning gains and the role of storytelling through levels of narrative transportation. The results show positive perception and learning outcome of chemistry, narrative transportation showcasing an opportunity for a unique form to approach chemistry using an edutainment format.
