OpenSciEd Unit 8.1 · Lesson 09 · 9.C
Update launcher system model
From Teacher Edition
Facilitation guidance from the lesson plan — what to notice in student thinking and how to respond while teaching.
Building towards
9.C Develop and revise a model to identify other parts of the system the cart and box are making contact with or colliding into that are producing contact forces on these subsystems, causing energy to be transferred to or from them as the box and cart travel down the track.
What to look / listen for
See Key for modeling force interactions in the launcher, cart, box, and track system for guidance on what to look for.
What to do
Treat this as a way to measure student growth in understanding from the previous copy you made of their responses at the end of Lesson 8 and the start of Lesson 10. Since you won’t have time to review their revisions until the end of day 1 of the next lesson, make sure you do that at some point during day 2 of the lesson, and definitely before day 3 of the lesson, so you can identify students who would benefit from talking through revisions to their models before working on the transfer task assessment items in Baseball Assessment 1 and Baseball Assessment 2.
