With advances in digital technology, the commercial use of augmented reality (AR) systems has been widely employed for software and hardware in education. Users can easily use marker-based AR systems to input pre-designed markers and then to conduct the new scenes by blending together the real world and computer-generated 3D images. Based on the AR technology, this research constructs an E-learning platform for scientific study of plant life by growing. The script of plant life has been created to show the growth of flowers through applying a series of markers. Children can use a camera to capture the information of multiple AR markers where interactions with 3D objects can be achieved through AR technology. By the interaction with variations of AR markers and time changes of the Arduino Clock, children learn the growth of plants during day and night. Accordingly, the results show that integrating AR technology into the curriculum can bring fun to learning and children would learn more through a mixed-reality virtual experience.
