Body System Model
Your challenge is to create a working model of one of the major body systems. The Model: Your model should meet the following requirements: -It should be built out of, used, found, or inexpensive items. -It should have moving or working parts that operate smoothly. -It should include 4 to 6 organs that work together in the system. -It should clearly demonstrate how the chosen body system works. -Your model need not look exactly like the organs it represents (think of Mr. Bixby’s heart model), but it should function in a similar way. For instance, pumps should actually pump, filters, should actually filter, absorbers should actually absorb, digesters should actually digest, muscles should move, fluids should flow. The presentation: When you present the model to the class, you should be an expert on the body system you chose. Prepare some notes to help you get through your presentation. Your presentation should Include: -The names of 4 to 6 important parts of the system -A clear description of how the system works -A well practiced demonstration of how your model works -Some suggested food to eat or activities to do to take care of the system you modeled. Hints: When you demonstrate your model, you can move the various parts by hand. They need not move on their own. Rubber gloves, balloons, tubing, and tape, can be useful in a lot of ways.
