Developing a Model of Thermal Energy, Atoms, and Molecules
Intended Grade Level(s):
6-8
Learning Goal(s):
Students will develop a model through collaborative inquiry to explain thermal kinetic energy and predict the outcome when heat is added to a substance.
Students will build argumentation from evidence skills through collaborative sense-making and gallery walk presentations.
Students will develop a model of atomic and molecular structures.

Description:
Through a series of exploration and inquiry activities, students will explain kinetic molecular theory, atomic, and molecular structures. Students will be challenged to gradually increase the precision of their explanation of molecular-level structures and motion. This lesson facilitates in the students’ development of an evidence-based argument through collaboration.
