Intended Grade Level(s):
Estimated Activity Length:
9 hours
Learning Goal(s):
  1. Students will develop a model through collaborative inquiry to explain thermal kinetic energy and predict the outcome when heat is added to a substance.

  2. Students will build argumentation from evidence skills through collaborative sense-making and gallery walk presentations.

  3. 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.
