This lesson aligns with the Common Core State Standards:
STANDARD 5 - Matter and Energy
"The competent science teacher understands the nature and properties of energy in its various forms, and the processes by which energy is exchanged and/or transformed.
5A. understands the atomic and nuclear structure of matter and the relationship to chemical and physical properties
5C. understands the cause and effect of chemical reactions in natural and manufactured systems
5E. analyzes the properties of materials in relation to their chemical or physical structures and evaluate uses of the materials based on their properties
5F. explains conservation of mass and energy and explains interactions of energy with matter, including changes in state"
Student note guide to the PowerPoint lesson I in the "Chemical Reactions" unit VI - introductory chemistry. This lesson describes chemical equations by using the terms reactants and products; balances chemical equations by changing coefficients and using the law of conservation of mass; defines the terms mole & molar mass, and calculates the mass of a reactant or product in a balanced chemical equation.
PowerPoint lessons contain many graphics and links to short videos to further student understanding.
PowerPoint slides also contain notes for the instructor based on students most "frequently asked questions" or FAQ's to help clarify the subject.
A class activity is included at the end of each lesson.
*All PowerPoint lessons; review programs; student worksheets/activities and assessments for this unit can be found under the "Introductory Chemistry Complete Unit VI Chemical Reactions" zip file folder.
Terms/concepts covered in this lesson include:
Law of Conservation of Mass
balanced chemical equation
atomic mass units (amu)
calculating molar mass
molar mass conversions
