Chemistry.1 The student will investigate and understand that experiments in which variables are measured, analyzed, and evaluated, produce observations and verifiable data. Key concepts include

• Multiple variables are manipulated with repeated trials;
• Accurate recording, organizing, and analysis of data through repeated trials;

Chemistry.2 The student will investigate and understand that the placement of elements on the periodic table is a function of their atomic structure. The periodic table is a tool used for the investigations of:

• Mass/atomic number
• Families/groups
• Series/periods
• Trends/patterns: atomic/nuclear radii, electronegativity
