lab questions number 2

1. In each lab I used a different tool to figure out what the answer was. I used a caliper to measure the length of the blood splatter and I used math formula to figure out which soil was from the suspect!
2. My approach is different, I used to go into it complaining and do not excited and now I think there fun. I am more confident now because I have done it more than once and I know how to check my answer to make sure it's correct.
