PHASE CHANGE MINI LABS
The Phase Change Mini Labs are a series of eight short experiments designed to help students observe, and to some extent, quantitatively measure, the effects of substances as they change from one phase to another.
The labs include:
The Great Evaporation Race - students compare the evaporation rate of water, alcohol, acetone and mineral oil.
Cold Sweats - students create condensation with crushed ice and salt.
The Heat Thief - students measure the effects of evaporation on temperature.
Frosty the Tin Can - students create frost (deposition) using dry ice or salt and crushed ice.
The Self-Contained Melting Machine - students measure melting and freezing using a low melting point alloy (Onion’s Fusible Alloy or similar).
The Rainmaker - students create “rain” by through evaporation and condensation.
Into Thin Air - students explore sublimation of dry ice.
The Deep Freeze - students explore freezing with water and dry ice.
