In this unit, students are challenged to solve a common problem - how to protect a cell phone from being damaged during everyday use? Throughout the unit, students use hands-on experiences and systems modeling to explore properties of force and motion, while planning and carrying out fair investigations for their cell phone case designs.

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