Identified the recent problem at Taco Bell using a variety of news resources.

1 point
Accessed only one news source. Did not clearly define the problem.

2 points
Accessed more the one news source. Was unclear in identifying the problem.

3 points
Accessed several news sources. Clearly identified the problem.

4 points
Accessed at least five news sources. Identified and clearly articulated the problem, citing news sources to support findings,

of 4

Used gathered information about Escherichia Coli Bacteria to make a table, spreadsheet, scatter plot, and equation representing the rapid growth of E-coli bacteria.

1 point
Very weak evidence of organization, a few correct answers. Missing several components of the required material - table, spreadsheet, scatter plot, or corresponding equation. Mathematical terms and symbol use are weak, not enough references to mathematical terms are used.

2 points
Organization needs improvement, some correct answers. Some of the required components are missing - table, spreadsheet, scatter plot, or corresponding Equation. Some mathematical terms and symbols are used correctly.

3 points
Organized and most answers are correct. All required components are present. Mathematical terms and symbols are used appropriately.

4 points
Well organized with correct answers. All required components are included. Mathematical terms and symbols are used appropriately and often elaborated upon.

of 4

Analysis and Synthesis of the problem are evident. Connections are clearly made between E-Coli and Exponential Growth. Correct predictions were made using the given data and information.

1 point
Very little evidence of analysis and synthesis. Some educated guesses. Accuracy is weak.

2 points
Analyzes and synthesizes the problem with some success, accuracy needs to improve.

3 points
Analysis of the problem is evident, considerable accuracy.

4 points
Thorough analysis of the problem with accurate solutions.

of 4

The email sent to the other student should be convincing and should include: -sufficient background information on the Taco Bell Scandel -an overview of why one should not presently eat at Taco Bell -explain how this relates to exponential functions. -background information about Eschericha Coli -a diagram showing how E-Coli grows -a table showing the independent and dependent variables -graph that represents this function -the corresponding equation with an explanation about how they are interrelated.

1 point
Demonstrates little understanding of the main concepts. Is missing many critical components that are to be included in the email.

2 points
Demonstrates a partial understanding of the main concepts. Is missing some of the critical components that are to be included in the email.

3 points
Demonstrates an understanding of the main concepts. Includes most of the critical components in the email.

4 points
Demonstrates a thorough understanding of the main concepts, which are consistently and clearly articulated throughout the email. All critical components of the email are accurate and included.
