Height Of Blood Drop Lab

The topic for science fair is on blood spatter. If terminal velocity and height van affect the radius of a blood spatter print. To figure out whether after a blood splatter reaches terminal velocity and it starts to slow down will the radius start to become decrease. In this experiment the independent variable is the height the blood is dropped from, and the dependent is the radius of the blood spatter. Independent and dependent variables: The independent variable is the amount of sugar in each solution and the dependent variable is the levels of vitamin C the solution has.

Blood samples from a volunteer within the group were used to conduct the experiment. The volunteer’s hands were thoroughly washed and an alcohol swab was applied to further sanitize the hands. To gather the blood samples needed, a lancet was properly placed on the forefinger and a firm pressure was applied, which activated the needle inside to

There are four blood types found in humans. These are A blood type which has the genotype either AA or AO, B blood type which has the genotype either BB or BO, AB blood type which has the genotype AB, and O blood type which has the genotype OO. These genotypes show a combination of complete dominance and codominance. A and B traits are dominant to the recessive O trait, however, the A trait is codominant to the B trait. Each blood type codes for certain antigens. A blood codes for the A surface antigen, B blood codes for the B surface antigen, AB blood codes for both the A and B surface antigen, and O blood does not code for a surface antigen. Therefore to determine one’s blood type a test can be performed

As I said about there are many forms of blood splatter patterns for example a single blood drop. Depending on the distance the blood drop as fallen from, it can be a little small drop to a more splattered expanded out drop. When a blood drop is affected by something other than force, it can change the characteristics of the blood drop splatter. Blood in flight is caused by a different source than gravity for instance a gun, or a heavy object. When you get shot blood splatters from the exit wound at a fast pace due to the velocity of the bullet. The direction the bullet went in can change the blood splatter characteristics and the distance it was shot at. A blunt heavy item can also cause blood splatter similar to a gun shot.

It is flung off the weapon or tool during and after the act as a result of centrifugal force. Cast-off spatter is often elliptical in shape which is why it is easily confused with arterial spurting (Sutton, 1998). However, it can also resemble a typical medium velocity droplet any time the blood hits a surface. For example, a blow to the top of the head with an over head strike or simply cast off forming from blood dripping off a weapon after use will result in a similar pattern to a medium or low velocity droplet. Smooth metallic weaponry used will generate a more profound pattern than a textured weapon. In other words an aluminum baseball bat will yield a greater amount of cast off blood than a wooden baseball bat.

In the Molly Wright case she was bludgeoned to death in her home and the blood stain patterns that I analyzed form the experiment where the point of impact was when she was hit there was a lot of blood located at the point Mrs. Wright was hit upon impact the area where Wright was struck the blood splatter did however splatter all around and the killer would have for sure had plenty of blood stains on their clothing along with the splatter landing on everything around where she was hit this would have happened every-time she was hit. After the first impact the blood splatter would have gotten worse and worse with the open wound located on her head where she was hit repeatedly with the blunt object.

We compared these measurements with the information we obtained in our blood spatter lab. The size of these drops was similar in size to the drops that dropped from about six feet. This means that the drop came from a person who was nearly six feet tall. The Loyola Rambler is six feet. However, he had a cut on his chin. This means that if the blood did come from him, it would fall from a height a few inches less than he is. That would put the drop height at a little less than six feet, which is consistent with the spatter

By 1865, Union soldiers perceived the bloodhound as a weapon by which the planter class oppressed not only slaves, but white unionists and northern prisoners of war. The savagery of the bloodhounds illustrated what Northerners considered to be the true brutality of the culture of the “Southern chivalry.”

A bachelor's degree in one of the physical sciences is typically necessary. Blood spatter analysts deal with various academic areas, such as physics, math, biology, and chemistry. Also, blood spatter analysts are expected to endure specific training. Regular teachings in blood examination have been established by the Global Organization of Blood Spatter Analysts (Roufa, ‘’How to be a Bloodstain Pattern Analyst’’). Besides the necessary blood spatter analysis program, other lessons and programs are accessible and highly suggested.

A 13 year old is studying blood in school, and has asked some questions that haven't been answered in class. I will answer

The Blood In My Veins is a creative response to Tjukurpa Kunpa, 2017, by Mumu Mike Williams and Willy Muntjantji Martin, senior men from the Anangu Pitjantjatjara Yankunytjatjara (APY) Lands. They created this piece together specifically for of the Tarnanthi Festival of Contemporary Aboriginal and Torres Strait Islander Art and is currently on display in the Art Gallery of South Australia.

In the Core Lab, I was assigned to hematologist named Melissa. She was very experienced in her work since she knew how to operate machines that help her detect any abnormalities in the blood samples. Regularly, the hematologists and other lab workers would work independently, and I like the method of independent labor because there won’t be any obstacles while testing in the lab. I also liked observing the blood samples through microscope and see whether the blood have any kinds of disease or irregularity. The hematology was very interesting and enjoyable; I was able to experience and learn that hematology is another way to test and figure out life threatening unusualness in the body.

My Systemic Juvenile Idiopathic Arthritis; that’s what set my mind to being a Medical Lab Technician. As an optimistic freshman, I had a mindset that my 4 years of high school would go smoothly with flying colors; I was taking my first college class, AP World History. However, mid-year that mindset changed. I had been having major knee pain for 2 weeks with high fever, it was agony. My parents immediately took me to the hospital because my primary physician thought I had Kawasaki. As we were waiting in the emergency room, I could feel my parent’s consternation. I’m the first born with one younger sister. I can’t picture how distraught my parents would be if their first child passed away at such a young age with so much academic potential. Along with that, it had been less than a year that my grandmother passed away so my mom was truly

Blood stains tend to come up often and have the tendency to be a pain to get out. Kerr comes right out and repeatedly tells us to not apply bleach to the blood stain. The result
