Colligative Properties Phenomena-Based Lesson: Sub-Zero Biological Survival of Antarctic Icefish in Supercooled Polar Seawater Presentation | Chemistry II | Grades 9–12

This is the student-facing slide presentation that introduces the phenomenon, walks the class through observations and driving questions, and frames the evidence students will use for the Phenomena-Based Lesson in the Chemistry II (grades 9–12) chapter Colligative Properties, built around the phenomenon Sub-Zero Biological Survival of Antarctic Icefish in Supercooled Polar Seawater. It is sold separately from the other two parts of the set.

Complete the set: Colligative Properties Phenomena-Based Lesson: Sub-Zero Biological Survival of Antarctic Icefish in Supercooled Polar Seawater Teacher Discussion Guide; Colligative Properties Phenomena-Based Lesson: Sub-Zero Biological Survival of Antarctic Icefish in Supercooled Polar Seawater Student Response Sheet. Scaffolded version: Colligative Properties Scaffolded Phenomena-Based Lesson: Sub-Zero Biological Survival of Antarctic Icefish in Supercooled Polar Seawater Presentation.
