  Conservation of Mass, Measurements, Conservation of Mass, Chemical Change, Observations, Physical Change, Chemical Change | High School, Middle School

  Lab: Mass & Change

  In this lab, students will use unified particle pictures of solid, liquid, and gas to explain the law of conservation of mass after carrying out various experiments.

• 

  Physical Change, Mixtures, Observations | High School, Middle School

  Activity: Magic Bubble

  In this lesson, students will create and interpret particle diagrams that represent elements and compounds at the molecular level. They will also describe the process of dissolving and create particle diagrams that represent mixtures at the molecular level.

  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).
