Augmented Reality technology has become widespread for conducting learning activities using mobile devices. In this research, a mobile system MAPILS was designed to conduct plant IBL activities using AR technology. The system consists of three main modules; learning, training and testing. The learning module presents information regarding four different plants including Lotus, Pine tree, Palm tree and Mushroom. Students have to use their mobile devices to target a particular marker and learn about a specific plant. The information will be displayed on their mobile devices once the student selects any part of a given plant by scaling up or down. After selecting a specific part of a plant then the information will appear about that part in the form of text. Also audio will be played if students require. Students enjoyed the use of such system that facilitates and motivates towards science learning.
