OpenSciEd Unit 6.3 · Lesson 01 · 1.A
Initial Model
From Teacher Edition
Facilitation guidance from the lesson plan — what to notice in student thinking and how to respond while teaching.
Building towards
1.A.1 Develop an initial model to describe changes and mechanisms at both the observable and the particle level that cause hail to fall during a brief time period.
What to look / listen for
See Pre-Assessment Reference for Students Initial Models for complete guidance on ideas to look for in the initial models.
What to do
Make a copy of the students' initial models for future reference so you can assess individual student growth between now and future key summative assessment points in the unit. Use your review of students’ ideas, as represented in their models, to get a sense of commonalities and differences across models and help you plan for the consensus model discussion on day 2.
