Mail Delivery System Model Limitations

The scale model maximum size can be no larger than:

       5 feet long

       5 feet wide

       41–45 inches high from the road surface

The scale model does not have to be the maximum sizes, but must use correct proportions. Students may bring “junk” materials from home with prior approval.

The scale model must function exactly like the full-size Mail Delivery System.

The full-size Mail Delivery System has a distance of 20 feet from the street-side mailbox to the house; the mailbox has a height of 41–45 inches from the road surface, and the mail weighs 8 ounces.

An Engineering Notebook is a professional notebook and known by several names depending on individual preference and the industry in which it is being used. The bound book contains the

time-sequential written documentation of the development of the author’s ideas, along with all notes, data, observations, calculations, and other information relevant to the discovery or experiment being conducted.   It provides an important record of the progress of an engineer’s, scientist’s, or inventor's work. When properly maintained, it may be submitted as a legal document for patent purposes or legal records.

The Engineering Notebook is the equivalent of a technical diary and has multiple uses. It presents the author’s thought process and work in an easy-to-access manner, allowing an author to confirm conclusions, details, and dates.

Engineering research and development organizations usually require their engineers to keep a running record of their activities. In the event that a project is shelved or the person leaves employment it can provide the paths of inquiry that have been investigated and can offer justification for decisions or courses of action taken. Contents include a synopsis of each journal article in addition to direct quotes that may be used in the final report. Research includes source documentation in proper APA style. The research synopsis can also identify articles of poor quality or no relevance to the project. The notebook includes definitions of new vocabulary that will be assessed in end products. All data are to be recorded directly into the notebook including notes and calculations. Elaboration of details is preferable. Write a daily reflection on new learning.

Use a bound notebook with a stitched binding such as a composition notebook. Do not use a loose-leaf or spiral-bound notebook.

Use ink, not pencil, for all entries.

Record the title, project number, and book number on each page.

Record all notes and calculations. Write a daily reflection on new learnings.

In the case of an error, draw a single line through the incorrect data. Do not erase or use correction fluid. All corrections should be initialed and dated. When making a correction, make a notation of the page number where the correct information is found.

After entering data, sign and date all entries. A witness or witnesses should sign and date each entry. The witness must observe the work that is done and have sufficient knowledge to understand what they have read. Names of all who were present during any demonstration, phone conversation, or discussion should also be recorded.

Never leave any white space: "X" out or crosshatch all unused space, and don't forget to initial and date the entry. Use both sides of the page.

When the notebook is full, begin a new notebook with the title, project number, and book number. Also make a notation of the preceding notebook number. Archive the full notebook in a safe location.

If necessary, items may be taped into the notebook with a handwritten date and title. Permanently attach inserted items (glue is preferred). Sign across the edge of the inserted sheet with half of the signature on the page.

Following this procedure will foster improved documentation, research, and sketching skills. It can help with time management. Early adoption will help with the required project reports.
