Refrigeration & the Production of Ice

by Veronika Maiseyenka, Andreas Henke, Anna Launus, Falk Rieß & Dietmar Höttecke

This case study addresses food storage in ice houses, use of freezing mixtures, the spread of domestic cooling and modern refrigeration to help convey several thermodynamic concepts: temperature; heat and thermal conduction; insulation; phases and phase transitions (melting, freezing and boiling); melting and boiling temperature; and freezing point and vaporization.

NOS features include:

• cultural context of science
• stepwise, but unpredictable development of scientific knowledge
• role of trial and error
