SC15.CHM.1
Obtain and communicate information from historical experiments (e.g., work by Mendeleev and Moseley, Rutherford’s gold foil experiment, Thomson’s cathode ray experiment, Millikan’s oil drop experiment, Bohr’s interpretation of bright line spectra) to determine the structure and function of an atom and to analyze the patterns represented in the periodic table.

Unpacked Content
UP:SC15.CHM.1
Vocabulary
- Atomic theory
- Periodic table history
- Macroscopic level
- Atomic/ molecular/ particulate level
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.
