Lesson Plan: Physical Properties of Metals and Nonmetals Science
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to identify and describe the physical properties of metals and nonmetals.
Objectives
Students will be able to
- list properties of metals, such as being lustrous, conductors of heat and electricity, malleable, and ductile,
- know that metals can be characterized by having less than 4 electrons in their outer shell,
- know that metals tend to lose electrons during chemical reactions to form positive ions,
- list properties of nonmetals, such as lacking luster, being neither malleable nor ductile (being brittle), and being bad conductors of heat and electricity (with the exception of graphite),
- know that nonmetals can be characterized by having more than 4 electrons in their outer shell,
- know that nonmetals tend to gain electrons during chemical reactions to form negative ions,
- identify whether an element is a metal or a nonmetal from descriptions or images,
- identify and briefly describe metalloids, which are elements with metal and nonmetal properties.
Prerequisites
Students should already be familiar with
- metals and nonmetals.
Exclusions
Students will not cover
- chemical properties of metals,
- chemical properties of nonmetals,
- ions,
- bonding with and between metals and nonmetals.
