Colligative Properties Scaffolded 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 Scaffolded 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. This scaffolded version adds sentence frames and extra supports for students who need them. It is sold separately from the other two parts of the set.

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