My son has to make a working model of a human body system. With trepidation and hope, I am asking for some advice. Here are the guidelines:
Do ONLY ONE system. You won't get any credit for more than one.
* The 'body' gets points because it shows me you know where the system is in the body and the approximate size of it. Make sure those 2 things are shown in your model. The 'body' can be a 1/2 body made of cardboard if you like.
* Don't use too much tubing, it is hard to get things thru alot of tubing using only 1 pump (as the heart), or peristalisis (as in digestion).
* Your hand can be the nerve to make things happen. Like you can pump the heart, or turn on a switch on an aquarium pump to start the circulatory system. Or your hand can pull up a tendon to make a muscle contract in the skeletal/muscular system
* Any part left out or the function not said when you present will not get points for the part. You must know them by heart, no cards or papers with you.
* Notice that if it is not a working system, the most number of points you can get is 85 (75 for the urinary system).
* It must work like the body works to get the working points. Example, you can't just pull up an arm and say it moves. Something like a rubber band must be shortened to make it work.
* Bones and joints in the skeletal system must all be different. Example, you can't use 2 hands and say you have 10 phlanges and 10 metacarpals. All the bones must be different. You must know the name and function of each one.
The system can be a working or non-working model. It must not be labeled ( I want to know that you KNOW the parts, not just able to read them).
I think my boy may be screwed.
You cannot use a pre-fab (store bought) model for the system, but you may use pieces of one in yours.
