DRAFT Literacy Design Collaborative Informational/Explanatory Teaching Task
Discipline: Science
Course: Chemistry 1
Grade(s): 10 - 12
Duration: 2 days (42 min pds) or 1 Block or Lab Period
Author(s): Joe Helinski, Robert Azar, Jeanne Knepper, Marc Snyder
Objectives
The students will:
Comprehend basic conversions involved with the mole
Apply mathematical methods to solve basic mole conversion problems
Synthesize the mole concept to other areas in chemistry
.Background Statement
The mole is the SI unit for measuring amount and was developed by chemists to manipulate very small
or very large quantities in science. The mole enables scientists to link mass, volume, and representative
particles. Students will utilize this unit to perform various chemical quantity calculations and
conversions. All of this will be accomplished with the understanding of topic relevant terminology and
techniques.
