	Does Not Meet 4 pts	Partially Meets 8 pts	Meets 12 pts	Exceeds 16 pts
Brainstorm and Choose Design Students work as a team to brainstorm several designs.	Does Not Meet Pre planning included only one idea.	Partially Meets Pre-Planning included two or less ideas that were well thought out.	Meets Pre-planning included several ideas that were well thought out and ingenuity. Model included labeled parts.	Exceeds Pre-planning included several ideas that were well thought out and ingenuity. Model included labeled parts and had a calculated cost.
Build Project Students build a model/prototype of the selected design.	Does Not Meet Design was poorly constructed and did not work.	Partially Meets Design was unstable and fell apart easily. However the design worked.	Meets Design was well constructed. The design was stable and easy to move.	Exceeds Design was well constructed. The design was stable and easy to move. It was visually pleasing.
Test & Evaluate Students test and evaluate the built model/prototype and observe how it works in order to improve it.	Does Not Meet Students poorly conducted a test to evaluate the effectiveness of their model. There is no written procedure and data is limited.	Partially Meets Students conduct a test to evaluate the effectiveness of their model. The procedure is poorly written and data is limited.	Meets Students conduct a test to evaluate the effectiveness of their model. The procedure is well written and data is sufficient. If the original design failed students retested after design alterations.	Exceeds Student conducts a well throughout test to evaluate the effectiveness of their model. The procedure is well written and data was collected in an organized table.
Redesign Students use test information to make modifications to the existing design in order to improve it.	Does Not Meet Students who have negative test results choose not to redesign.	Partially Meets Students use test results to improve original design.	Meets Students use test result to improve original design . They redraw a new model to show the improvements.	Exceeds Students use test results to improve original design. They redraw a new model to show the improvements and explain why those improvements were needed.
Test Final Project For Success "Test & Evaluate" continues until the product is successful.	Does Not Meet Students do not do a final test to evaluate the effectiveness of their design.	Partially Meets Students do a final test to evaluate the effectiveness of their design. They do not collect data or follow the same procedure as the original design.	Meets Students do a final test to evaluate the effectiveness of their design. They collect data but do not follow the same procedure as the original design.	Exceeds Students do a final test to evaluate the effectiveness of their design. They collect data and follow the same procedure as the original design.
Write-up Each group presents a lab write-up. The lab write-up must be typed.	Does Not Meet Students submit a write up that is unorganized and does not have all required sections.	Partially Meets Students submit a write up that is organized but missing one or more of the required sections.	Meets Students submit a write up that is organized and has all required sections.	Exceeds Students submit a write up that is organized and has all required sections. The write up has pictures of design in the brainstorming and final design. Also a modified design if needed.
