This is a FUN and EXCITING lesson on the sublimation of DRY ICE!! My students LOVE it and talk about it all year long! Great for elementary or middle school teachers when learning about physical changes and/or solids, liquids, and gases! This lesson is COMPLETE with a step-by-step guide with questions and answers for each experiment!!
