C. Steps must be concise and precise. Limit the number of words used (as short as possible) 
       Ex. The operator should turn the knob now=Turn the knob 
D. The person reading the manual must know exactly to what degree an action is to be performed 
       Ex. Turn the knob(wrong) 
       Turn the knob 1/4 turn clockwise 
E. Refer to labeled drawing when applicable (ex. Turn knob "A" 1/4 turn clockwise) 
F. Warnings must be included BEFORE a step if physical danger or danger to a machine is present or possibly present. The warnings should stand out. You may want to use capital letters, underlining, bold, color, etc. to call attention to the warning. 
       Ex. WARNING: Engine is hot 
G. Notes should be used periodically at the END of a step to let the reader know he/she has performed the task successfully. You want the note to be noticeable (underline, bold, etc.) 
       Ex. Note: When the bolt is removed, oil should begin draining. (You may also want to include a statement to suggest what should be checked if there is an error.)
H An illustration is required in each manual. (This could be your scaled drawing.) 

Rubric - Information #4

Oral Presentation: This is rubric as well as a guideline that the student should follow when presenting both the project and the career paper. The teacher should also assign a point value to each section of this handout. One suggestion is a point system of 1 to 5 with 1 indicating least and 5 indicating most effective. In addition it would beneficial to have a peer editing session.

2. Was it clearly described? 

3. Was the presentation fluent and articulate? 

4. Was the presentation successful in communicating/describing the topic?

 
  Instructional Activities
 
This project has approximately 15 planned hours. This plan can be modified to take place between 1 to 3 teachers. Ideally, a math, a science and an English instructor are needed. All three teachers can provide a cornucopia of ideas as well as information that will enable students to achieve maximum results.

Day One: Hours 1 - 3 - Explanations

1. Review Simple Machines   

Simple Machines:  

  • Machines make work easier. People use a variety of machines each day. Computers, bicycles, pencil sharpeners and scissors are examples of simple machines. A machine is a mechanical device that makes work easier.
  • Machines may be powered by engines or electric motors and others are powered by people. Some machines are simple and others are complex.
  • A simple machine is a mechanical device that accomplishes work with only one movement. There are six types of simple machines: lever, pulley, wheel and axle, inclined plane, screw, and wedge.
  • A lever is a bar that is free to turn around a fixed point. The fixed point of a lever is called the fulcrum. When a person uses a tire tool/crow-bar to pry a tire from a bicycle wheel, that person used the tire tool as a lever. A seesaw is another example of a lever.
  • A pulley consists of a grooved wheel with a rope or chain running along the groove. When a student raises a flag on the flagpole, he or she uses a pulley to move the flag to the top of the pole.
  • A wheel and axle is a simple machine that consists of two wheels of different sizes that rotate together. Doorknobs, ice-cream makers and faucet handles are wheels and axles. On effort force is usually applied to the larger wheel. The smaller wheel, the axle, exerts the resistance force. For example, consider a water faucet with a broken handle. Without the faucet handle (wheel), the shaft of the faucet (axle) is difficult to turn.
  • An inclined plane is a sloping surface that is used to raise or lower objects. What if you wanted to load a lawn mower onto a truck? You could try to lift the lawn mower onto the truck or you could use a simple machine - an inclined plane. An inclined plane would make the work of leading the lawn mower easier since you could roll the mower up and down the sloping surface.
  • The screw and wedge are examples of inclined planes that move. A screw is an inclined plane wrapped in a spiral around a cylinder. The threads of the screw are composed of an inclined plane or ramp that winds from the bottom of the screw to the top.
  • A wedge is made of two inclined planes. A doorstop is an example of a wedge. The two inclined planes work to hold the door open. Chisels and ax blades are also wedges that are simple machines.
  • Many machines are made of two or more simple machines. A combination of simple machines is a compound machine.
2. Create 3-D Art Project- Students will create a project the illustrates all six simple machines. These will be presented and posted around the room.  

3. Introduction to Unit- Goals of project, results, assessment, show examples.  

a. Cover rules and regulations 
b. Homework: Identify at least one example of each of the five types of simple machines
4. Video Review of Simple Machines 
Discovering Simple Machines: Video Project.
