Sample Lesson Plan: Introduction to the Periodic Table of Elements
Submitted by: Kristen Demick, Chemistry Teacher, Melrose High School
Content Objectives: To learn what an element is and the factors by which they are
arranged on the Periodic Table.
Class opener/Do Now: Students will have 90 seconds to write down as many “elements”
as they can think of. Then, as a class, students will share their lists, and a list of elements
will be formulated on the board.
Mini-lesson: Begin with visual aides; explain how elements make up objects in every
day life; exist in different phases (solid [Au and Ag jewelry], liquid [Hg in thermometer],
gas [He in balloon]).
Introduce the Periodic Table:
What is an element?
o The simplest form of matter; cannot be decomposed into simpler
substances; matter
o composed of one kind of atom, each atom has same properties; atoms all
have the same atomic number
Break down into name and atomic symbol
o Ex: Carbon
o Review subatomic particles from previous unit (electrons, protons,
neutrons)
o Atomic number (Z): number of protons in atomic nucleus
