Phases
Name: Warm-up
Minutes: 2
Purpose: Activate students' prior knowledge of physical vs. chemical properties so they are ready to sort gas evidence into those two categories, a distinction they need for objective 2. It also introduces the logic of elimination (objective 1) through a familiar non-science example before the teacher models it with gases in the I Do.
