7.1: Field Forces 3 Dimensions & Progressions

Unit 2

●​ CER Scaffold for Writing ●​ Lesson Plan ●​ Gravitational Models pre-made ○​ Washers, straws, yarn or string

●​ I can explain how mass and distance change gravitational inertia.

●​ Students use the

gravitational model as pictured, and now should be able to use evidence

from this activity, simulations, labs,

readings, etc. to explain why the added weight and length of string increase or decrease gravitational speed (Inertia).
