If you are asked to make a simple scientific model on how the digestive system works what type of model will you use? Describe how you will create it.
Answer (1)
A 3D physical model using recycled materials like cardboard, balloons, and colored strings.How to make it:Materials Needed:Cardboard (base)Balloons (stomach and intestines)Plastic straw (esophagus)Yarn or rope (small intestine coils)Colored paper (liver, pancreas)Steps:Cut the cardboard into a rectangle (as base).Use a red balloon for the stomach, a blue balloon for the large intestine, and colored yarn for the small intestine (coiled).Glue the straw from the top down to connect the mouth to the stomach (as esophagus).Attach the other organs in their correct places: liver, pancreas, and intestines.Label each part clearly.Why this model works: It helps visualize how food travels through the digestive system and where digestion and absorption happen.
