3D biology model, digestive system.
The model is fixed to a plate of polystyrene with needles. This way I can unhook it and use it in the classroom.
First I knitted a long tube with only 4 stitches. This was later rolled up and sewn. Doing it this way to get the flexibility of the intestine that can be stretched both longitudinally and in across, to simulate the peristale movement (bowel movement). Oral cavity, throat, stomach and duodenum was knitted with straight stitches because the bowel movement is not important in this part of the digestive system.
The plate of polystyrene is intended for storage. The model is taken down when it is used and hung up when lessons/play is finished. The model works both when it is on the plat and when it is taken down. As a display you can add names to and as a tactile model to see and feel how the digestive system work.
Creating this model did take much time. It is not difficult but enormously time-consuming. Should I have knitted a new digestive system, I would have chosen a thinner yarn and I would have made more stitches. The movement of intestinal section would have been much better. I would also have chosen to separate the different parts with different colour so that they would be easier to identify. Maybe this type of project is something you can do together with friends or collage.
