Classroom Resources: States of Matter
1 – 4 of 4 Classroom Resources
Ionic Bonding, Naming Compounds, Molecular Formula, Ions, Ionic Radius, Solubility, Melting Point, Physical Properties | High School
In this lesson, students will demonstrate their knowledge of ionic bond strength and its relationship to the properties of melting point and solubility using a “brackets” activity. After analyzing the ionic charge and radius to predict the strongest and weakest bond between four pairs of ionic substances, they will then determine which will be the least soluble.
Intermolecular Forces, Intermolecular Forces, Polarity, Molecular Motion, Molecular Motion, Physical Properties | High School
In this activity, students will use a simulation to investigate different types of intermolecular forces (London dispersion, induced dipole, and hydrogen bonding). In the analysis that follows the activity, they will relate IMFs (also including dipole-dipole) to physical properties (boiling point, solubility, and vapor pressure). This activity and simulation are appropriate for students in any level chemistry course.
Entropy, Kinetic Molecular Theory, Molecular Motion, Intermolecular Forces, Density, Volume | High School
In this activity, students use blocks to model different states of matter and the Kinetic Molecular Theory to understand the concept of entropy. This is a concept mandated by SAT level or AP level high school chemistry class.
Intermolecular Forces, Polarity, Molecular Motion, Intermolecular Forces, Molecular Motion, Physical Change, Physical Change | High School
In the November 2014 issue, students explore the different attractive foreces between pairs of molecules by dragging the "star" image. In the accompanying activity, students investigate different types of intermolecular forces (London dispersion and dipole-dipole). In the analysis that follows the investigation, they relate IMFs (including hydrogen bonding) to physical properties (boiling point and solubility).
