Exploring Molecular Scale in Phase Changes

This lesson focuses on modeling molecular scale changes during phase transitions. Students engage in activities such as creating dances to represent molecular movement, collaborative writing about videos, and using a modeling tool to simulate methane phase changes. The lesson concludes with an explanation task and a self-assessment to evaluate understanding.

What is the main focus of Lesson 1.6?

• Understanding chemical reactions

• Modeling molecular movement during phase changes

• Learning about atomic structure

• Studying the properties of solids
