Digestive System Project Proposal
foam tubing (2 sizes, ¾” and 1 ¼” diameter, pink or red preferably)
plastic container, like tupperware or something, pokie has one
water
cotton candy (used during demonstration)
string
a rectangle of fabric, 10” x 6”
something to make the liver and pancreas out of, clay or styrofoam maybe
wooden board (plywood) to support the parts of the model 3 ½’ x 2’
human skull (pokie will supply)
hot glue, nails, a hammer
pink or red paint if we are unable to get colored foam tubing
5. Construction plan: Our plan is to start by drawing the outlines of the different parts on the plywood so that we use the space well. We will use nails or hot glue to attach the organs to the plywood once we have assembled them separately.
6. Principles used: cotton candy dissolves in water. Gravity causes the food to travel down the esophagus towards the stomach. The human skull can open and close its jaw, crushing the food.
7. We are unsure of which material would be best for making the liver and the pancreas. Since these two parts are not functioning, it should be easier to make them than the mouth and stomach, and it will not affect any other decisions.
8. We do not having any special requests/requirements so far on our model.
Digestive System Project Proposal
- The model will represent the functions of the esophagus, stomach, and the mouth. The esophagus carries food after it is chewed by the mouth. The next step of the digestive process is the journey to the stomach, which will be the second function of our model. The parts of the model that do not function will be the small intestine, large intestine, the liver, and the pancreas. These parts will not function, but they will be used to be a visual representation of the digestive process.
- Pokie will draw the proposed model.
- The function of the mouth is to show the food being mechanically chewed and broken down by saliva.The second function that the model will perform is the transfer of food and liquid. This will be shown using a pipe and soft materials that can pass through to represent food. The main function of the stomach is to hold and digest food after the esophagus. The food enters through the muscular valve called the lower esophageal sphincter. We’ll show the esophageal sphincter by using a pliable material and string. We will use a holder to be the stomach that can be attached to the esophagus. The stomach will have a liquid that will dissolve the food.
