The materials and videos provided here provide an “on ramp” to help teachers implement this unit in classrooms. Together, these resources provide condensed information about the unit as well as essential background content.

In this unit, students use what they’ve learned about forces and motion to design a protective cell phone case that meets criteria and constraints. Throughout the unit, students use hands-on experiences and systems modeling to explore properties of force and motion, while planning fair investigations for their cell phone case designs.

Unit Challenge Question: How can we design a case that protects a cell phone from breaking?
