Trajectory Lab

How can the angle of impact of a bullet in a wall be used to determine other critical information about the scene of a crime? 
 you can figure out where the gun was when it was shot by measuring the bullet with a dowel and figuring out the degrees. 

 How might this lab be helpful in preparing you for the mission? 
well if there is some sort of impact on the space shuttle we might be able to measure and go through the same process as we did with this lab.
