Scientific and Engineering Practices
Obtaining, Evaluating, and Communicating Information
Crosscutting Concepts
Structure and Function
Knowledge
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.
Skills
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).
Understanding
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.
Vocabulary
- Atomic theory
- Periodic table history
- Macroscopic level
- Atomic/ molecular/ particulate level
