Dry Ice Lab

To further capitalize on the big day of October 31st, students made their own drink for our Nevada Day party, using both math and science.  After reading about the history of rootbeer and how to make a 5 gallon recipe, students used their math skills to convert the recipe so that we only made 2/3 of it.  Since it was carbonated using dry ice, we saved some and incorporated teh dry ice into a lab before lunch.  Students learned about sublimation (going straight from a solid to gas) and other unique properties of dry ice. 

The rootbeer turned out great, but due to the -103 degree dry ice, which did a fantastic job of carbonating the beverage, it also froze the bottom half of our drink.  This didn't seem to matter to many students, as they soon learned that "slushy rootbeer" tasted great!
