Why does our phone screens break on some collisions but not others?

In the 8th-grade science class, we wanted to know why sometimes our phones break during a collision and other times they do not.  To figure this out we are investigating collisions. One of the experiments we did was hitting a lasagna noodle with a variety of different things, to model a cell phone screen in a collision. The noodles usually ended up getting shattered if they were hit hard enough and they were usually hit hard enough because they are super fragile. Some of the stuff we hit the noodles with are books, pens, markers, and toy cars. In the end, it was a fun experiment, and I think the whole class enjoyed it.  Next, we viewed three different collisions in slow motion to get an understanding of how motion and shape change during a collision.
