Chemapalooza 7-28: So Sublime

Today students observed first-hand how regular ice and dry ice differ in their behaviors. Students studied both types of ice in one scenario, and used their observations to predict what would happen in a different scenario! Finally, collected evidence to make claims about the strange phase-changing properties of dry ice, created models, and presented them to the group.

Ask your student:  What is it called when a substance goes from a solid straight to a gas? (Sublimation) Ask your student to tell you some of the differences they observed between dry and regular ice.
