forensics labs

1) what role do multiple observations/ experiments play in making good inferences and conclusions in each case?

because in forensics you want to be sure about your results, so just one test will not tell you for sure if you are right or not. So if you do multiple test you can compare them all to see exactly what the answer is.

2) when is it hard to be precise and how does this affect the confidence in your results? what did you do about this?

It is hard to be precise when things happen like if you don't have the right amount materials or if you don't have the right materials, then your data that you collect will be wrong. or if you measure something wrong it will affect your results so you have to be very careful.when this happens you have to either start all over or try to fix you mistake because you still want to be accurate.

3)when can you rely on "known" data to match up with and when do you need to generate your own? what is the difference?
when you are not sure if your data is correct or if the data given is right then you have to go further in your research. But if you know your data that you were given is correct then you can rely on that you don't ave to go any further in your reaserch.

BLOOD LAB

In my group the height did not effect the size of the drop very much. the purpose of multipul drops is to make sure you are accurate so if you are off the first time then you can do another drop and be more accurate.

Like i said before the height of the pipette did not really effect our group to much. But maybe the higher you went the bigger the diameter of the the blood drop would be. I don't think i can accurately infer the height of a blood spatter drop from the diameter because the data was to close in numbers to infer anything.

“Hey Marty are you ready to go to the park” this is how my day started! Oh sorry I forgot to introduce myself I’m Marty Marie Anderson I’m 6 years old, my moms name is Lucile Anderson and well I don’t know how old she is. Well my mom works a lot I mean a lot a lot! But I guess you kind of have to work a lot when you are a sergeant, a brain sergeant to be exact! So my mom promised that she would take me to the park Saturday, play any game I wanted, and afterwards take me to lunch! “Yes mom” I yell “I am ready” she says “then what are you waiting for lets go.”

My mom and I are off to the park, not just any park, the park down the street with the perfect grass, the swings with the chairs, the HUGE play structure that consist of 4 slides, 2 sets of monkey bars, multiple levels, it has it ALL. So when mom and I arrived at the park we played tag, soccer, hide and seek, more tag my feet clonking as I try to run away from my mom she and I are both laughing beyond belief. And then we got ice cream from the ice cream truck which I was very surprised because mom never lets me have dessert before a meal!

Mom and I left the park we headed to lunch we went to my favorite little hot dog stand and I got a plain hot dog no ketchup, no mustard, and NO relish just dog and bread! My mom Lucile doesn’t like this stand very much but today was about me not her so she ate a hot dog with me; except hers had ketchup and mustard GROSS! After lunch my mom surprised me and we went a fed the ducks which is my FAVORITE Thing to do! There were tons of ducks, ducks every where quacking and waddling, swishing and splashing water. Wow what a day!! “I love you mom you’re the best”; “I love you to Marty and no you’re the best!!”

hiiiiiiiiii people!!!
