Obtaining, Evaluating, and Communicating Information

Structure and Function

Students know:

Examples of scientists and scientific discoveries that changed our knowledge of atomic structure.
How these scientific discoveries relate to the information found on the periodic table.
Each atom has a charged substructure that consists of a nucleus, which is made of protons and neutrons, surrounded by electrons.
The periodic table orders elements horizontally by the number of protons in the atom's nucleus and places those with similar properties in columns.

Students are able to:

Obtain information from multiple, grade-level appropriate materials (text, media, visual displays, data).
Communicate information from a variety of reliable sources in multiple formats (oral, graphical, textual, and/or mathematical).

Students understand that:

It is important to gather, read, and synthesize information from multiple appropriate sources and assess the credibility, accuracy, and possible bias of each publication and methods used.
Our knowledge of the structure and function of the atom changed over time due to scientific discoveries, and the history of the periodic table traces our understanding of the atom.
Macroscopic patterns are related to the nature of atomic/ molecular/ particulate level structure.
