FoReNsIcS lAb

1) when we were working on each lab we had to stay observant because otherwise you didn't get work done. one example of both the good and the bad are when i was working on the firearms and ballistics lab we weren't really trying that hard in the second go round to get things done and we just gave up. while in the fibers lab and the soil lab we stayed on task with only some slip ups a.k.a when we were working on the fibers lab we accidentally blew out the flame many times and also got a large clump of fabric in the flame. during the labs when we were working to solve the case it was important to look closely at each specimen. one such instance was during the fibers lab when we were looking at the different fibers under the microscope we had to look at the crime scene fiber then the other fibers and see if they looked similar, also when were burning the cloth we had to make sure to make good observations in order to make inferences to find out which suspect was guilty.

2) it was hard to be precise when we were fully involved in the process one instance was measuring in the soil lab, we couldn't be sure of the amount of soil or water needed and we couldn't make the weighing system exact so when we were weighing soil to make 25 grams it wasn't exact and wavered between below the zero and above the line. another instance was in the fibers lab when we were burning the material we couldn't be sure if we were burning the same amount of fiber or not, also wether or not we could actually see what a strand of each fiber looked like while the suspect fiber was in a strand so you couldn't see what the crime fiber looked like when it was in a piece of fabric.

3) when we were following the instructions to get to a point in the firearms and ballistics lab, the fibers lab and the soil lab we were using known data to get to a point that was when we started to generate our own data. in the fibers lab we generated our own data when we drew the fibers and when we burned them. in the soil lab we generated our own data when we were measuring the soil and filtering it though the water. in the firearms and ballistics lab we generated our own data when we were measuring the bullets and coming up with the weight diameter and texture. the difference is that our ideas are guided and then once we generate our own data we create our own hypothesis and theories to come up with the answer.
