During today’s 7th Grade Science Lab, students explored phase changes by making observations at both the macroscopic and molecular levels. Students observed changes they could see and measure while also developing models to represent what was occurring at the molecular level.
The goal of the lab was for students to observe, model, and explain phase changes across both scales, with a particular focus on how the motion and arrangement of molecules change as matter transitions from one phase to another. This hands-on investigation allowed students to connect observable evidence to the molecular processes responsible for those changes.
