Module: Molecule Exploration
Goals related to understanding: Students will be able to obtain, organize, and analyze structural data and describe trends and patterns in the data that have to do with bonded vs. non-bonded distances, repeated occurrence of a set of limited angles, and trends in distance of hydrogen element bonds as the elements change across a period.
Assessment item (assignment, test item, etc.): Submit a written report on twelve molecules that recognizes trends and patterns in data of molecules with regard to distances and angles. Trends and patterns should be correlated with the characteristics of the molecules or atoms involved, such as position in the periodic table, electronegativity, bonding, and completeness or openness of electron shells.

Accurate and complete	Accurately describes structural types and classify molecules within them as: linear, planar, or tetrahedral. Accurately uses the concepts of electronegativity, atomic size, and completeness or openness of electron shells to categorize molecular arrangements.	Does not use structural types or concepts or uses them incorrectly.	Does not recognize most structural types or uses them in an inappropriate way.	Recognizes the structural types and concepts but does not apply this recognition.	Recognizes the structural types and concepts and uses them appropriately.
Coherent and integrated	Consistency in statements related to number of electrons in the molecule, position in the periodic table, completeness of electron shells, atomic size and relative electronegativity. Recognizes the relationship between electronegativity and atomic size, and between bonding length and molecular arrangement.	Does not make connections between concepts or recognize commonalties between molecules of the same types.	Uses only some of the concepts. Connections are correct and consistent but incomplete.
Appropriate representational form	Converts diagrammatic data to tabular form that recognizes redundancies in the data. Converts tabular data to diagrams that show proper structural arrangements. Associates these arrangements with appropriate chemical terms.	Does not draw diagrams or these are incorrect. Terms are not used or not used properly.
Appropriate inferences and justifications	Identifies patterns of similarities and differences in bonding angles and lengths across molecules and makes and tests inferences that use these concepts to explain the patterns.	Does not attempt to explain patterns. Does not identify patterns or the patterns are incorrect.	Explanations are undeveloped. Categorizes incompletely or improperly. Identifies patterns incorrectly.	Explanations correct but not fully developed. Categorizes appropriately. Recognizes patterns correctly.	Recognizes patterns correctly. Categorizes appropriately. Explanations correct and fully developed. Novel insights.
