Students create, analyze, and interpret thermal curve models and use the colligative property freezing-point depression to determine sample purity and identify an unknown. They connect prior knowledge about states of matter with intermolecular forces to better understand what happens on a molecular level during phase changes. General lab equipment, including forty-five 100-mL beakers, is needed but not included. Materials support 15 student pairs.

Using heating-curve models, cooling-curve models, and the colligative property freezing-point depression, students determine a sample's purity and identify an unknown mixture. They also build an understanding about the role intermolecular forces play during a substance's phase changes. General lab equipment, including forty-five 100-mL beakers, is needed but not included. Materials support 15 student pairs. Note: Finely crushed ice (needed but not included) is recommended for optimal results. If a source of finely crushed ice is not readily available, then the desired consistency can be achieved using a blender or any mechanical device designed to convert ice cubes or chunks into a snow-like texture.

This kit is designed to be incorporated into a larger unit of instruction consisting of multiple experiences and taking place over several weeks. Anchoring phenomena for a larger unit of instruction may be derived from the following topics:

  • Thermochemistry
  • Colligative properties
  • The properties of the states of matter
  • Properties of ionic and covalent bonds

Kit includes free 1-year access to digital resources that support 3-dimensional instruction for NGSS.

  • This item is only available from Carolina Biological Supply Company.
