This lesson aligns with the Common Core State Standards:
STANDARD 5 - Matter and Energy
"The 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"
PowerPoint lesson III in the "Chemical Reactions" Unit VI - introductory chemistry. This lesson identifies energy changes that occur during chemical reactions; describes chemical reactions as exothermic or endothermic; and explains how energy is conserved during chemical reactions. A kahoot.it 20-question interactive quiz is also included (link is in the last slide). The quiz/review is lesson-specific and a fun way to check for student understanding of the material.
A separate student PowerPoint worksheet for this lesson is also available.
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:
breaking chemical bonds
instant ice packs
law of conservation of energy
