Classroom Resources: Chemistry Basics

76 – 77 of 77 Classroom Resources

• 

  Molecular Motion, Density, Physical Properties, Density, Gas Laws, Ideal Gas, Temperature, Pressure, Volume | Middle School, High School

  Simulation: Density

  The simulation for the September 2015 issue allows students to investigate the effect of changing variables on both the volume and the density of a solid, a liquid, and a gas sample. Students will analyze the different states of matter at the particle level as well as quantitatively.

• 

  Intermolecular Forces, Polarity, Molecular Motion, Intermolecular Forces, Molecular Motion, Physical Change, Physical Change | High School

  Simulation: Comparing Attractive Forces

  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).
