Classroom Resources: Molecules & Bonding
1 – 2 of 2 Classroom Resources
Ionic Bonding, Bond Energy, Electronegativity, Intramolecular Forces, Lewis Structures, Polarity | 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.
Molecular Structure, Molecular Geometry, Bond Energy | High School
In this activity, students participate in an introductory level computational chemistry investigation. Students will interact with computational software to conduct this activity and will analyze data to determine the best bond angle and bond length of a water molecule.
