Watch as students see a pile of "snow" sublimate before their very eyes! This teaches the phase change from solid to gas (sublimation). Use this as a demo, "mini lab" or classroom activity!
Originally designed as a high school demonstration, this is easy enough to be used in middle school, and safe for most elementary school classrooms. Simply modify how much of the "science behind the demo" you explain.
Included for this demonstration:
1) List of materials
2) Step-by-step instructions
3) DETAILED and THOROUGH explanation of the science behind each demonstration. The scientific explanations are advanced enough for high school Chemistry.
**NOTE** You will need the a carbon dioxide fire extinguisher for this demonstration (dry ice can be used if a CO2 extinguisher is not available)
