Related Rates Project

This project requires that the students collect data regarding the radius of a sphere and then use this information to determine the rate of change of the radius. Using this information, students will then determine how fast the volume of the sphere is decreasing.

Process of Experimentation	Poor No description of the process was given.	Fair Process is labeled, but no information is provided.	Good Process is included but it is hard to make sense of.	Great Process is included, however it is a bit vague or confusing, possibly difficult to follow.	Excellent A process is explained in depth in a clear and concise manner as to what was done.
Rate of Change (Radius)	Poor No explanation nor work is provided for the rate of change of the radius.	Fair Little explanation and work is provided. The model used to determine the rate of change of the radius is not provided, unclear, or incorrect based on the data and graph provided.	Good An explanation and work is provided but is sketchy or unclear. The model used to determine the rate of change is incorrect based on the data and graph provided.	Great An explanation and work is included describing how the rate of change was determined but is confusing or vague.	Excellent A clear and concise explanation and supporting work is provided describing how the rate of change of the radius was determined.
Possible Errors	Poor The paper does not explain any errors or mistakes that were made.	Fair The paper briefly talks about errors or mistakes that were made.	Good The paper talks a little about errors or mistakes that were made.	Great The paper talks about possible errors or mistakes, but it fails to cover it in depth.	Excellent The paper explains in depth what some possible errors or mistakes were.
Conclusion	Poor No conclusion is provided	Fair Conclusion provides little information or is very difficult to make sense of. No solution is stated.	Good Conclusion is confusing or hard to read. A solution is stated but omitted units or used incorrect units.	Great Conclusion is vague or has some difficult parts to read. A solution is stated using the correct units.	Excellent In depth conclusion is given. A solution is stated using the correct units.
Spelling	Poor Student presents their project with 7 or more spelling/grammar errors.	Fair Student presents their project with 5 - 6 spelling/grammar errors.	Good Student presents their project with 3 - 4 spelling/grammar errors.	Great Student presents their project with 1 - 2 spelling/grammar errors.	Excellent Student presents their project free of spelling and grammar errors.
Data	Poor Includes 6 or fewer different points.	Fair Includes 7 different points.	Good Includes 8 different points.	Great Includes 9 different points.	Excellent Includes at least 10 different points.
Graph of the Data	Poor No graph is provided.	Fair A graph is provided but is missing three elements or includes three errors. No model is included on the graph.	Good A graph is provided but is missing two elements or includes two errors. No model is included on the graph.	Great A graph is provided but is missing one element or includes one error. The chosen model is included on the graph.	Excellent An accurate graph of the data is provided. A title is included and the axes are clearly and accurately labeled and includes an appropriate scale. The chosen model is included on the graph.
Accuracy of Calculations	Poor No work is provided and/or four or more errors are present.	Fair At least three errors are present. No units are indicated.	Good At least two errors are present. Incorrect units are used.	Great Related rates calculations of the volume are difficult to follow, steps are incomplete and/or at least one error is evident. Correct units are used.	Excellent Related rates calculations of the volume are accurate, complete, are easy to follow and contain no errors. Correct units are used.
