The Soil Lab: For the soil lab, it is important to make sure you measured the exact amount of soil and water. If we didn't measure 25 grams of soil then it might not match up to the crime scene and the other soil being tested. This rule also goes for the water. We also want to always check to make sure that when we measure the PH and Conductivity we get the right numbers and wait till the line stops. This helps make sure that we can match it up to the crime scene.
The Fiber Lab: It was important for this lab to make sure that we didn't touch the fibers because our hands have oils on them so they might act different to the fire or look different under the microscope. Then we would get different results of what the crime scene matched up too.
2. It was hard to be precise when we were doing the fiber lab because there are no exact numbers or measurements that we had to be precise with. Because of this factor, we had to draw exactly what we saw and try to burn the flame as perfectly as possible to get the same out come as the crime scene. It was also hard to determine which was the groove and which was the land from the bullet lab.
3. From a lab like the Soil lab it is important to keep in mind the Conductivity, PH, general appearance and the water absorbency when you figure out which matches up with the crime scene. It is important to do this so the match doesn't just match up with one of them, it matches up with all of them. For the bullet lab it is important to keep in mind the different things when you are figuring out what type of bullet it is. Finally, for the fiber lab it is important to match up all together both the notes from when we did the flame experiments and when we looked at the fibers under a microscope.
