Human digestive working model making, in this course helps students understand the process of digestion through a creative, hands-on science project. In this course, learners will study the structure and functions of the digestive system, including the mouth, esophagus, stomach, intestines, liver, and pancreas. Step-by-step guidance is given to design and build a working model using simple materials such as plastic bottles, tubes, balloons, and clay to represent different organs. The model demonstrates how food travels through the digestive tract, how it is broken down into nutrients, and how waste is expelled from the body. Alongside practical construction, the course explains key concepts like mechanical and chemical digestion, enzyme action, and nutrient absorption in the small intestine. Students will also learn the importance of a healthy diet for maintaining digestive health. By the end of the course, learners will have both a clear theoretical understanding and a functional model that makes the complex process of digestion easy to visualize, ideal for classrooms, science fairs, or home experiments. howtofunda
