Students propose a data analysis plan for information received from the Mars Science Laboratory Curiosity rover based on patterns present in the physical properties of ionic and covalent compounds. Students will work toward answering the driving question, “How can you make and defend a claim about the types of chemical bonds in compounds based on the patterns present in evidence collected in the lab about their physical properties?”

Learning Objectives

• Use the periodic table of electronegativity to predict whether a substance's chemical bonds are ionic, polar covalent, or nonpolar covalent.
• Analyze and interpret data on the properties of unknown substances to classify them as ionic or covalent compounds.
• Observe patterns of the properties of substances at the macro scale to provide evidence for the type of bonding at the atomic scale.

Prerequisite Knowledge and Skills
Students should be familiar with the structure of the atom, the significance of valence electrons, and the organization of the periodic table.
