The Periodic Table of the Elements


Content Source:

Type: Lesson/Unit Plan


The periodic table is an essential part of any chemistry course. Its simple chart-like appearance belies the wealth of information that it contains. In this lesson, students learn about the origin of the modern periodic table of elements and explore an interactive version that teaches them how to extract information from it. This activity is the first of three lessons. The Strange World of the Electron and Repeating Patterns: The Shape of the Periodic Table will help to further students' understanding of this powerful tool.

Content Standard(s):
SC2015 (2015)
Grade: 8
Physical Science
1 ) Analyze patterns within the periodic table to construct models (e.g., molecular-level models, including drawings; computer representations) that illustrate the structure, composition, and characteristics of atoms and molecules.

Alabama Alternate Achievement Standards
AAS Standard:
SCI.AAS.8.1- Identify parts of an atom (i.e. protons, neutrons, electrons); recognize that the periodic table is organized to show patterns of common traits of elements; locate metals and nonmetals on the periodic table.

SC2015 (2015)
Grade: 9-12
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.
