Helmet Lab Report

Should people under the age of 18 be required to wear a protective helmet while skateboarding, in-line skating, bicycling, snowboarding and skiing? I believe truly believe so. The thrill in these activities, are to speed jump tricks and ride.

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

The game that America has come to know and love may have more behind it than everyday viewers and fans realize. Physics fuels every aspect of the game of football and is evident in the collisions that take place on every play. Watching a game of football can be a great learning tool to anyone interested in better understanding the laws of physics. Many great examples are provided on every snap. Mass, force, momentum, velocity and torque all play significant roles in the tackling action performed by players and the better you understand these terms the better you can begin to understand the game itself.

For this project, I made a capsule for an egg that is to be dropped from about twenty feet. This capsule that I made was not what I was thinking at first but when I started to build it, I saw that this capsule would hold better than the one that I was thinking which was a triangular capsule with the egg in the middle but I saw later one that the egg would break if it hit one of the flat sides. The capsule is a cube that is made out of the tongue depressors and I used most of the yarn for the big cage and I used the Elmer’s glue to glue the tongue depressors together. I used pieces of the paper clips to hold the popsicle sticks together with the tongue depressors and some

My unknown organism #6 is Morganella morganii, which is a gram-negative bacillus rods commonly found in the environment and also in the intestinal tracts of humans, mammals, and reptiles as a normal flora. (3, 5) This bacterium Morganella morganii, was first discovered in the 1906 by a British bacteriologist named H. de R. Morgan. (2) Despite its wide distribution, it is an uncommon cause of community-acquired infection and is most often encountered inpostoperative and other nosocomial settings. (2, 3) Morganella morganii infections respond well to appropriate antibiotic therapy; however, its

The purpose for the students of the Energy of a Tossed Ball Lab involved learning how to measure the change in kinetic and potential energies as a ball moves in free fall. Since there is no frictional forces working on the ball the total energy will remain constant and the students will see how the total energy of the ball changes during free fall.

A team of researchers and engineers at the University of Michigan undertook a four-year challenge sponsored by the NFL to create a helmet with better protection from brain injuries from sports. Current helmets worn by football players, including the pros, reduce the force put on the skull during a collision. However, the current helmets do

There is a lot of rising controversy surrounding minors and high-impact sports like football. From Elementary age kids playing little league to high school football, an increasing number of studies are surfacing that are showing many negative effects surrounding head trauma. Some experts are even calling for the sport to be banned from middle and high schools. The concerns surrounding head trauma have existed in the NFL for numerous year, and these concerns brought foreword extensive new research in detection, effects, and prevention. Even today the NFL plans to spend 100 million dollars on new prevention and treatment options for concussions. The shock absorption technology used in football helmets has made advanced majorly in the last 10 years, yet concussion rates are increasing. With the risk of head trauma having long term consequences, especially in minors with developing brains, the ideas of terminating the sport take root. Although serious, these risks are far outweighed by the benefits of football that a substitute sport can not provide: The answer to how to make football safer for minors is much simpler and cheaper than advancing technology.

During the majority of a regular season of NFL, there is an average of 92 head injuries caused by helmet to helmet contact. It has also been estimated that high school football players have suffered around 11.2 concussions for every 10,000 practices and games. Among college players, the number was around 6.3. Over the years, researchers have been trying to improve the capability of a football helmet to withstand a stronger impact that will decrease the risk of the player getting a concussion. If we took the structure of a woodpecker's beak and applied it to a football helmet, it could possibly be a safer alternative and decrease the risk of concussions.

Football is one of the most sports that involve interaction with other players, such as the opposing team. The interactions can lead up to very dangerous injuries. Especially injuries leading to concussions. Researchers are working to prevent concussions and minimize the rate of head injuries created by direct impact lead by injuries from football.

Have you ever had a concussion. Were you wearing a helmet. Well even though helmets cannot prevent every concussion but they definitely lower the number of concussions every year. Helmets save lives said Dr. Nav Persaud a doctor at a family center in toronto. There are about 70 cycling deaths per year with helmets we could lower that by 28.5 %every year. In some places around the world it is illegal to not wear a helmet if you are below the age of 18 which proves that helmets can prove concussions.

There is a dark cloud hanging over the world of contact sports and it is growing at an alarming rate. With the size and speed of today’s athletes, the sports of football and hockey have become more exciting, fast paced, wide open, and fun to watch. However, there is another consequence of these ever growing athletes on their sports. They have made the collisions in them increasingly more violent. The velocity that these athletes hurl themselves through the air has created an atmosphere that could not have been imagined when these sports were created. Although the athletes’ bodies have become

The creation of the Head Impact Telemetry System (HIT) and Star System offered ways to measure helmets in the level of protectiveness. Despite its capability of measuring linear acceleration and impact location, the HIT system is unable to measure angular acceleration accurately(2). Scholars state rotational and linear is not suitable in predicting concussions(5).With that, future innovation and improvement will provide better insight in understanding these test and concussions(1). Still,Regardless of the effectiveness of the product, helmets will never be perfect in preventing injuries(1).

Unknown lab report# 24 Introduction Microbiology is a study of organisms that surrounds us every day. It requires an educational understanding to identify organisms, and the ability to distinguish different bacteria’s. In applying the learning process of the different bacteria’s, unknown bacteria samples are given to be studied and identified.

An unknown was given to our group from the professor. The unknown was in nutrient broth, the group received unknown number 3. And the task was to identify the unknown and try to make an educated guess, and identify the unknown #3.
