Lecture 29 - States of matter. In this lecture, revisit the concept of state of matter with Students. The first part of the week focus on exploring states of matter and changes of states of matter in hands-on activities. The inquiry provides them with a shared experience to build a foundation for more detailed group and class discussions. In those sessions, you will introduce particle theory and discuss the models of states of matter. | Lecture Science 1 - Associate Degree in Education: Lecture 29 - Dr. Arshad Bashir
