Your project will be graded based on the following scoring rubric.

Outcomes w/criteria

Scale

Score

1. Purpose

Wrote a clear purpose which describes the basic direction of the study.

0

Failed to include a purpose statement in the lab report.

1

Included a purpose, yet it is long-winded and/or poorly stated.

2

Purpose of study is clearly and succinctly stated.

 

 

 

______

2. Procedure

A numbered step-by-step procedure for collecting and analyzing data is provided. Procedure is accompanied by diagrams which show where the photogates (or motion detectors) are located and the direction of the carts before and after the collision.

0 - 2

Procedure is incomplete or fails to provide suitable direction for completing the data collection process.

3 - 4

Procedure is written which allows for the collection of data; its value is limited by one or two serious errors and/or omissions (e.g., lack of numbered steps, insufficient details, lack of diagrams, etc.)

5 - 6

A step-by-step, numbered procedure is written; procedure is complete, clear, and specific; details of how to set up equipment and to collect and analyze data are fully described; procedure is accompanied by meaningful diagrams.

 

 

 

______

3. Theory

The physics of collisions is exhaustively described in the Theory; included verbal descriptions, diagrams, graphs, numerical examples and discussions and other visuals which have been discussed in class or found in the book or other literature; application of physics to collisions revealed a high level of understanding.

0 - 2

Physics understanding is very limited as demonstrated by the lack of depth, several errors, failure to depict information in visual manner or merely the absence of a Theory section.

3 - 4

Made a clear effort to use both words and visuals to describe the physics of collisions; understanding level is still developing as evidenced by errors and a lack of depth and analysis in the Theory section.

5 - 6

Used a wealth of physics to fully describe collisions; introduced free-body diagrams, p-t and v-t graphs, Newton's laws, momentum equations and analyses, and calc'ns; understanding of physics is well developed and evident in the Theory section.

 

 

 

______

4. Data

Completely collected accurate data and reported it using a well-organized table with a row-column format. Sample calculations are provided for each major calculation performed. Data collection reflects care and analysis shows that total system momentum was conserved; percent error or difference calculations were used.

0 - 4

Data section is incomplete, highly inaccurate, very disorganized or even non-existent.

5 - 6

Data is presented and labeled using a row-column format; there may be significant errors, inaccuracies or omissions which hinder the effectiveness of the experiment; presentation of data may lack clarity.

7 - 8

Accurate data was collected; % error and difference values are low for most trials; data is clearly presented in a row-column format; data are presented in an organized manner such that the consrv'n of momentum in each individual trial can be easily evaluated; sample calc'ns are shown.

 

 

 

______

5. Discussion of Results

Results are thoroughly discussed and include a statement about the qualitative and quantitative (eq'n) relationship; sources of error and technical problems were identified and discussed. Results of the study were interpreted and related to physical theories and models.

0 - 2

Failed to intelligently discuss the meaning of the data and results; discussion suffers from many serious errors and/or omissions.

3 - 4

Conclusions were drawn and relationships were discussed; may have one or more serious errors and/or omissions.

5 - 6

Relationship (direct, inverse, linear, parabolic, etc.) between variables is clearly stated; eq'n relating the data is properly written using the symbols for the variables (and not y and x); interpreted results and drew meaningful conclusions; provided an intelligent discussion of errors.

 

 

 

______

6. Report Organization

Report includes all the appropriate sections; info is placed in its proper section; each section is labeled and placed in its appropriate order; spelling is checked and corrected.

0

Report fails to include all the appropriate sections; includes several errors or omissions.

1

Lab report is mostly complete;may failed to have to provide appropriate organization or labeled sections.

2

Lab report is well-organized, complete, and labeled. With few exceptions, spelling has been checked and corrected.

 

 

 

______

Comments:

TOTAL

______

(out of 30)

Your score is _____/30; which is scaled to a ______________%.

 

Exemplary (for the most part) projects are included online at The Refrigerator; a quick glance at these pages is highly recommended prior to the completion of your project. Such examples are not included for you to mimic, but rather as helpful illustrations of what your own end product might look like. Students should be cautioned that project guidelines change through the years and thus the online exemplars should not be considered as the definitive word concerning what should be included in the final lab report. The definitive word are the guidelines which are included on these Internet pages.
