Fiber Analysis

(polyester)
(cotton)

(whool)
(silk)









This experiment was perticullarly interesting to me. Before doing this experiment I thought all fibers looked the same but I guesse I was proved wrong. Anyways it was interesting to see the different colors and textures through the microscope. This experiment made me want to look at so many other things that i have never thought to be interesting!

Blood Typing

There are four general blood types. There’s A, B, AB, and last but not least O. Based on the RH factor each can be either negative or positve. Every person has one blood type and this determines which blood is compatible with your body. This is especially important to doctors who give blood transfusions for if you do not receive the right blood type, it could be fatale. In class we tested for the different blood types based on reactions, visible changes in color, and changes in consitency. After doing this experiment using fake blood samples I wanted to know my blood type useing real blood and so I went to the doctors and they determined that my blood is type B+ . I am glad to know this information for future references!

Crime Scene Investigators have come to a conclusion. No crime was committed at Luela’s Hair & Beauty Salon which is located on Salseberry Street. It turns out that on Tuesday afternoon, Jenny Cho and salon manager Sam Tilson had a quarrel about Jenny’s frequent smoking breaks. Sam explained that Jenny had one week to prove that she could work with less breaks or else she would be fired. A few days later, Jenny comes to work early Monday morning. When she walks in she notices that someone has left food in the trash overnight which has made the room smell. She takes it to the dumpster and after returning sprays some perfume around the room. At this point she is not worried about the mud that she has tracked into the salon. Within ten minutes her first client of the day walks in. As she finishes cutting the gentleman’s hair Sam enters the room and asks her to come into his office before lunch. Knowing she is likely to forget Jenny grabs an orange marker and writes it down on a nearby tissue and puts it in her pocket. Hours go by and so does Jenny’s lunch break. Forgetting her meeting with Sam she returns from lunch to find Sam standing at her door. He is unpleased and has a slight nose bleed which often occurs when he is mad. Jenny is suddenly aware that she is in trouble. As she sits down Sam shows her a record of how many breaks she has taken within the last three days and tells her she is fired. Not believing she has lost another job and furious that Sam didn’t give her a second chance, she storms passed him meanwhile stubbing her foot on the door frame and leaving a puddle of blood on the floor. Without knowing what had previously happened the next client that came into the salon was astonished at the blood on the floor and called the police fearing that a murder had taken place.
