Lesson Plan: History of the Periodic Table Chemistry • 7th Grade
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the history of the periodic table and the organization of elements by atomic number and other parameters.
Objectives
Students will be able to
- outline the development of the periodic table from Dalton to Newlands to Mendeleev,
- state the successes, limitations, and flaws in each version of the periodic table,
- explain how the arrangement of the periodic table changed in response to new experimental data,
- outline the way in which Mendeleev left gaps in the periodic table and how his predictions were supported by the discovery of new elements,
- show patterns of properties within the periodic table to develop an understanding of the elements,
- explain the principles by which the modern periodic table is arranged to develop familiarity with the periodic table.
Prerequisites
Students should already be familiar with
- elements and atoms.
Exclusions
Students will not cover
- the electronic structure.
