  • Nylon string (cut to whatever length you need)

Machines
  • Band Saw
  • Drill Press
  • Disc Sander

Hand Tools
  • Wood File
  • Sandpaper

V2 2012 - The PRODUCT Evaluation
  • PLANS
    • Does the final product match the original plans? Were your measurements accurate?
  • DESIGN and BUILD**
    • How complex and intelligent was the design?
    • How skillfully was the product built?
    • Are the components symmetrical and balanced?


*

    • FINISH
**
    • How carefully did the student manufacture and finish the product?
    • Is if free of excess glue, pencil and scratching?
    • Has it been skillfully sanded?
  • FUNCTION
    • Does the product function as intended?
    • Are the parts well balanced and accessible?
    • Does the final product function well?

V1 2011
Construction
Level 1- Poor
Level 2 - Fair Attempt
Level 3 - Competant
Level 4 - Exemplary
Plans: Does the Product match the original plans?
The final product doesn't appear to match the original plans
The final product appears to match some, but not all specifications from the original plans
The final product generally matches the original plans, with slight variations due to finishing
The final product matches the original plans PRECISELY!
Symmetry: Are the flywheels parallel? Is the axel at a perfect 90 degrees?
The product is completely misaligned
The product isn't exactly symmetrical, but it was a fair attempt
The product is almost perfectly symmetrical
The product is PERFECTLY symmetrical
Wheels: Are the flywheels perfectly round?
The flywheels are irregular and poorly balanced
The flywheels are not circular and or balanced, but it was a fair attempt.
The flywheels are almost perfectly circular and balanced
The flywheels are PERFECTLY circular and balanced!
Finishing: Finishing Quality
The finish of final product is quite poor. Glue, poor sanding and little care mar the product.
The finish of final product is fair, but greater care should be observed.
The finish of final product is generally good. Sanding is with the grain, excess glue is minimal
The finish is exceptionally skillful - great care is evident!
Result

TIJ1O PROJECT PLAN RUBRIC

Specific Skill or Objective
Level 4 - Exemplary
Level 3 - Competent
Level 2 - Partially Proficient
Level 1 - Poor
Alignment
All objects CLEARLY align between the three views
All objects GENERALLY align between the three views
SOME objects align between the three views
Objects do not align between the three main views
Feasibility / Completion
The plans illustrate all necessary components, clearly demonstrate innovative design, and include useful detail to help make the product
The plans illustrate all necessary components of a workable design
The plans illustrate some of the components, but omissions or flaws exist that would compromise the production
The plans illustrate components that are incomplete or infeasable
Dimensions
All dimensions are displayed exceptionally well - clear, neat and without redundancy
All necessary dimensions are generally displayed well.
Dimensions are displayed, but may be incomplete, redundant, or may require a change of font size or format to be read clearly.
Key dimensions are not displayed, or are illegible and would compromise the production of the project.
Fit and Format
The elements in the plans are sized exceptionally well - objects fit each view fully, but don't appear cramped, and the printout is sized perfectly for landscape display. The author's name is clearly printed along with the project descriptions
The elements in the plans are generally sized well and printed in landscape orientation. The author's name is clearly printed along with the project descriptions
The elements in the plans are generally legible, but the sizes could make better use of the page borders. The size or orientation of the printout could be improved by following the printout steps more carefully.
The elements in the plans are poorly sized, compromising their legiblility.
