The digestive system, hence digestion of food is usually one of the topics taught at the secondary and tertiary levels of education. Often, this topic is taught using teaching aid in the form of diagrams or charts drawn on plane papers. The inanimate nature of these teaching aid employed makes learning less interesting and comprehension difficult. This paper presents the design and construction of a semi animated digestive module with remote control that visualizes the movement and process of food digestion in the body. Basically, the system consists of carved wooden digestive organs with light emitting diodes (LEDs) carefully fixed on the path of digestion. A remote control is also built to aid remote access to the module. These LEDs start to blink indicating swallowing from the mouth down to the anus illustrating the process of digestion which also involves the production of enzymes. A comparison of with the improved teaching aid will make conventional types showed that it aroused student, interest during teaching and learning process. It also reduced too much abstract explanation. Thus making teaching more efficient.
