Propose Solutions/ Hypothesis: A strong acid is needed to clean dirty pennies.

Select one:

a.
4 - Proposes one or more solutions/hypotheses that indicate a deep comprehension of the problem. Solution/hypotheses are sensitive to contextual factors as well as all of the following ethical, logical, and cultural dimensions of the problem.

b.
3 - Proposes one or more solutions/hypotheses that indicate comprehension of the problem. Solutions/hypotheses are sensitive to contextual factors as well as the one of the following ethical, logical, or cultural dimensions of the problems.

c.
2 - Proposes one solution/hypothesis that is “off the shelf” rather that individually designed to address the specific contextual factors of the problem.

d.
1 - Proposes a solution/hypothesis that is difficult to evaluate because it is vague or only indirectly addresses the problem statement.

Evaluate Potential Solutions/Prediction: If a strong acid such as vinegar is used, it will clean dirty pennies.

Select one:

a.
4 - Evaluation of solutions is deep and elegant (for example, contains thorough and insightful explanation) and includes, deeply and thoroughly, all of the following considers history of problem, reviews logic/reasoning, examines feasibility of solution, and weighs impacts of solution.

b.
3 - Evaluation of solutions is adequate (for example, contains thorough explanation) and includes the following, considers history of problem, reviews logic/reasoning.

c.
2 - Evaluation of solutions is brief (for example, explanation lacks depth) and includes the following considers history of problem, reviews logic/reasoning, examines feasibility of solution, and weighs impacts of solution.

d.
1 - Evaluation of solutions is superficial (for example, contains cursory, surface level explanation) and includes the following, considers history of problem, reviews logic/reasoning, examines feasibility of solution, and weighs impacts of solution.

Identify Strategies/Set up Experiment:

1. Try to clean pennies in a strong acid.
2. Try to clean the pennies in a weak acid.
3. Try to clean pennies in water.
Select one:

a.
4 - Implements the solution in a manner that addresses thoroughly and deeply multiple contextual factors of the problem.

b.
3 - Implements the solution in a manner that addresses multiple contextual factors of the problem in a surface manner.

c.
2 - Implements the solution in a manner that addresses the problem statement but ignores relevant contextual factors.

d.
1 - Implements the solution in a manner that does not directly address the problem statement.
