compound machines which can be made up of many different types of
simple machines. One material could be listed as being composed of
more than one type, sometimes all six, simple machines.
- You will get a day or two make sure you examine every material brought
into class. A Lab write-up is due just for part A one-week after part
A is completed.
Part B:

one partner design a model, using three or more of the simple machines
studied.
- This part will count for a test grade you must produce seven materials
to communicate your product. Two Drawing of your model with all the
simple machine parts labeled. B) A List of the materials you would
use to build your machine. C) A Cost analysis of how much each part
