HS-PS1-2: Simple Chemical Reactions
Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
Connection
These standardized tests often include questions that assess the understanding of basic chemical concepts like ion formation and ionic bonding. Students may be asked to:
Predict ion charges based on the periodic table.
Identify the components of an ionic compound.
Apply nomenclature rules to name or write formulas for ionic compounds.
Understand the properties of ionic compounds.
Day 1: Introduction to Ions and Ionic Bonding
Description: Students will learn about ion formation and the basics of ionic bonding.
Purpose: To understand how and why ions form, and how they combine to create ionic compounds.
DOK Level: 2 (Conceptual Understanding)
Day 2: Ionic Compound Nomenclature
Description: Students will learn and practice naming ionic compounds and writing their formulas.
Purpose: To develop systematic naming skills for ionic compounds.
DOK Level: 3 (Strategic Thinking)
Day 3: Lab Activity and Assessment
Description: Students will conduct a lab to observe the properties of ionic compounds and complete an assessment.
Purpose: To reinforce concepts through hands-on experience and evaluate understanding.
DOK Level: 3 (Strategic Thinking)
Discuss the importance of electrolytes in sports drinks and their connection to ionic compounds.
Explore the role of ionic compounds in traditional foods (e.g., salt in preservation techniques).
