Classroom Resources: Molecules & Bonding
1 – 5 of 5 Classroom Resources
Polarity, Ionic Bonding, Electronegativity, Bond Energy, Intramolecular Forces, Lewis Structures | High School
In this lesson, students will discover that dissolving salts changes the temperature of a solution even though it is a physical change. Students will first collect data during an investigation to compare the temperature change when dissolving three different salts (NaCl, KCl, and CaCl2). Then students will use magnets to construct an explanation of the temperature change based on collision of particles and properties of the metals.
Intermolecular Forces, Polarity, Covalent Bonding, Ionic Bonding, Molecular Structure, Metallic Bonding, Intramolecular Forces | High School
In this project, students will develop a presentation to explain how and why a specific material can solve a problem. The explanation will involve researching the properties of the material and how its properties are suited for solving a specific problem.
Observations, Physical Properties, Mixtures, Solubility, Intermolecular Forces, Polarity, Identifying an Unknown, Intermolecular Forces, Chemical Properties, Intramolecular Forces, Mixtures | High School
In this lesson, students determine whether unknown substances are polar, nonpolar, or ionic by testing their solubilities.
Naming Compounds, Ionic Bonding, Intramolecular Forces, Ions | High School
In this activity, students will construct ionic compounds by balancing the charges on cations and anions.
Physical Properties, Mixtures, Solubility, Melting Point, Intermolecular Forces, Freezing Point, Polarity, Molecular Structure, Solute & Solvent, Intermolecular Forces, Boiling Point, Intramolecular Forces, Graphing, Mixtures, Lewis Structures | High School
In this lesson, students investigate how intermolecular forces effect physical properties by investigating substances’ melting points as well as solubility.
