4 ) Plan and conduct an investigation to classify properties of matter as intensive (e.g., density, viscosity, specific heat, melting point, boiling point) or extensive (e.g., mass, volume, heat) and demonstrate how intensive properties can be used to identify a compound.

Subject: Science (9 - 12)
Title: The Sublimation of Dry Ice

In this activity, students will watch a quick video clip from YouTube that will demonstrate how dry ice can quickly freeze fruit, discuss properties of dry ice, and show how it sublimates. After watching the clip, students will then conduct seven different mini-laboratories with dry ice to expand their knowledge of the properties of matter and explore the process of sublimation - a solid transitioning directly to a gas skipping the liquid phase.  

This activity was created as a result of the ALEX Resource Development Summit.
