8th+Simple+Machines+in+the+Civil+War

1. Choose ONE from the rubric: Diagram, Model, or Prototype. 2. Research a simple machine or compound machine made up of more than one simple machine used in the Civil War. 3. Diagram, build a model, or build a prototype of your machine. 4. Write or label: (Can be paragraph or bullets) 2 pts a. what type of simple machine(s)? 2 pts b. describe your machine (ex: an inclined plane is a like a ramp, which reduces effort force by spreading out the effort force over a large distance) 2 pts c. what is the mechanical advantage of your machine? 5 pts d. how was it used in the Civil War? 5 pts e. how did it make work easier?
 * Simple Machines in the Civil War:**

RUBRIC: **__Civil War Simple Machine Project:__** For this project you have the choice of making a diagram of a simple machine from the civil war era, making a scaled model of the simple machine, or making a working prototype of the machine. Though it is only required that you make one of these, doing multiple will earn you extra points. For example, if you make a model and a diagram, you would get the sum of the points for each one. The grading will be as shown: **__Diagram:__** ______/ __100__ points **__Model:__** ______/__100__ points **__Prototype:__** _______/__100__points
 * || 25-20  ||  19-10  ||  9-0  ||
 * Neatness ||  Neat handwriting and straight drafting lines.  ||  Able to be read by most people.  ||  Barely or not at all understandable.  ||
 * Creativity ||  Use of an uncommon or new machine in your diagram.  ||  Use of a common machine as your draft.  ||  Use of a simple object as your machine.  ||
 * Labels ||  Labels accurately describe the use of each part of the machine.  ||  Labels accurately describe some parts of your machine.  ||  Labels are inaccurate or describe very little of your machine.  ||
 * Accuracy ||  Machine looks exactly scaled in your drawing.  ||  Machine is slightly in correct in the scaled drawing.  ||  Machine is scaled incorrectly and does not appear to be what it is.  ||
 * || 25-20  ||  19-10  ||  9-0  ||
 * Neatness ||  Model is neatly made with no unnecessary parts.  ||  Model is discernable by most average people.  ||  Model is unknown at the first glance of what it is.  ||
 * Creativity ||  Use of an uncommon or rare machine in your model.  ||  Use of a common machine as your model.  ||  Use of a simple object as your model.  ||
 * Simple Machines ||  Use of at least 3 simple machines in the compound machine.  ||  Use of 2 simple machines in the compound machine.  ||  Use of 1 or no simple machines in your compound machine.  ||
 * Appearance ||  Machine appears to be a realistic model.  ||  Machine is slightly incorrect in the production of the model.  ||  Machine is poorly made.  ||
 * || 25-20  ||  19-10  ||  9-0  ||
 * Neatness ||  Prototype is neatly made with no unnecessary parts.  ||  Prototype is discernable by most average people.  ||  Prototype is unknown as to what it is at first glance.  ||
 * Creativity ||  Use of an uncommon or rare machine as your prototype.  ||  Use of a common machine as your prototype.  ||  Use of a simple object as your prototype  ||
 * Working Parts ||  2 or more working simple machines in your prototype.  ||  1 simple machine that works in your prototype.  ||  No moveable parts on your prototype.  ||
 * Directions for Operation ||  Typed directions that tell you exactly how to operate the machine.  ||  Typed or written directions that tell how to work some of the machine.  ||  Poorly written or no directions for operation.  ||
