Halloween-Dry Ice Lab

The day after Halloween, our science lab focused on a substance often seen around this holiday, dry ice.  Students carefully observed it both in and out of water and connected their observations to states of matter, including sublimation and deposition.  They learned: how it was made, what it was made out of, how many soft drink companies carbonate their beverages, and how dry ice often forms over the water ice on the poles of Mars.

On another note, soon we will be exploring the science behind tie dye.  We are in need of ziplock bags (gallon size), latex gloves, lots of newspaper, and empty 2 liter bottles.
