In this article I am clarifying you on how to make the human digestive system working model science project for exhibition – diy easy & simple
Creating a human digestive system working model using cardboard, colored paper, pipes, syringes, and colored water is an engaging way to understand the process of digestion. Here’s how you can build this model:
Materials You’ll Need:
- Cardboard sheets (for the base and structures)
- Colored paper (for representing organs)
- Plastic pipes or tubing (to simulate the digestive tract)
- Syringes (to mimic muscle contractions)
- Colored water (for simulating food movement)
- Craft knife or scissors
- Hot glue gun and glue sticks
- Craft supplies for decoration (markers, stickers, etc.)
Step by Step Guide on how to make the digestive system model
- Prepare the Base:
- Cut a piece of cardboard to use as the base of your model.
- Create the Organs:
- Cut and assemble colored paper to represent different digestive organs such as the mouth, esophagus, stomach, small intestine, and large intestine.
- Attach these paper organs to the base using hot glue to create the digestive system layout.
- Assemble the Digestive Tract:
- Use plastic pipes or tubing to connect the different paper organs in sequence.
- Create bends and curves to mimic the path of the digestive tract.
- Attach the Syringes:
- Attach syringes at strategic points along the digestive tract (e.g., one for stomach, one for small intestine) using hot glue.
- These syringes will simulate the muscle contractions that move food along the digestive system.
- Add Colored Water:
- Fill the digestive tract with colored water to represent the movement of food.
- Push and pull the syringes to create peristalsis-like motions, simulating food being digested and moved through the system.
- Model Interaction:
- Gently push and pull the syringes to mimic the contraction and relaxation of muscles along the digestive tract.
- Observe how the colored water moves through the pipes, representing the journey of food.
- Decorate the model with craft supplies to enhance its appearance and make it visually appealing.
This model provides a hands-on way to learn about the human digestive system and its processes, from ingestion to absorption. It’s a creative and interactive way to understand the functions of different digestive organs and how food is broken down and transported through the body.
