    You should go into detail about how the case was solved and add more information on the history. The pictures were really good and they helped show how a bullet enters the body and the different wounds. The video analysis was a great idea to add. Good job explaining the difference between a contact wound and a distant wound and the skin’s reaction to the bullet. Great job!

    You didn’t really go into specific detail about the history of bite marks. I think the timeline should be a little more detailed or you should discuss the history somewhere else on this page. Great pictures! I like how well u went into details about how to identify the bite marks and how they are recognized. You did a really good job on this project, it is very detailed.

    What lipstick and cosmetics are made out of
    Cosmetics are made with organic or natural ingredients. Mineral make-up, also known as foundation powder, is mostly made with ingredients from the earth. It contains zinc oxide, mica, and titanium dioxide which also function as sunscreens. Lipstick is made out of waxes, oils, and emollients. In order to give lipstick its shape different types of waxes such as beeswax or carnauba wax will be used. Some lipsticks contain carcinogens such as formaldehyde or coal tar to give it color.

    History
    Cosmetics were first introduced by the Egyptians as early as 10,000 B.C. Egyptians used scented ointments to soften the skin and dyes or paints to add color to the skin, body, and hair. They colored their lips and cheeks and lined their eyes and eyebrows with kohl. Kohl is a dark-colored powder with crushed antimony, burnt almonds, lead, oxidized copper, and many other ingredients. Egyptians believed that kohl eyeliner would improve eyesight and minimize the risk of getting eye infections. It is believed that the Jews adopted the use of makeup from the Egyptians, since references to the painting of faces appear in the New Testament section of the Bible.

    Cosmetic relation to forensic evidence
    Cosmetics, after being applied on an individual, now has the individuals DNA on it. If cosmetics are found at a crime-scene, they must be analyzed for further examination and comparison. Forensic scientists can try and match the evidence of cosmetics found at the crime scene to a specific brand or also to the same cosmetic as the suspect has in their possession. This evidence would have to be processed and carefully evaluated for any strands of not contaminated DNA.

    Lipstick prints and smears
    Lipstick prints and smears can be used as evidence at a crime scene the same way finger prints can. If the scientist compares the smear at a crime scene from the victim, they can show proof of some sort of relationship between the suspect and victim. It is very easy for lipstick smears and foundation to accidentally get onto other clothing or surfaces. In some cases, it can be possible to gather saliva which will contain DNA from the lipstick print.

    court case. Gas chromatography can be used to separate a lipstick stain from another material and then separate the DNA that is on the lipstick stain. Gas chromatography is a chromatographic process in which a mixture of gases or vapors are separated by their differential absorption by a stationary phase. Infrared spectroscopy can identify and study the chemicals that are in the cosmetic substances to determine the specific brand, match it to the manufacturer, and then match it to the victim or suspect. Infrared spectroscopy focuses on the infrared area of the electromagnetic substance. It is based on absorption spectroscopy.

    Great pictures used! However, a timeline would be a great addition. You didn't go into depth with how art forgery has helped solved the cases you talked about. Add more detail and you should be good!

    Great amount of information! Very nice job in the explanation of mitochondrial DNA. A little wordy and kind of hard to understand at some points with all the writing. Great job overall though.
