I. Fetal Pig Dissection II. Purpose Sus scrofa‚ or the domestic pig is a member of the class Mammalia and the order Artiodactyla. Since we as humans are also a member of class Mammalia‚ we have a good deal in common biologically with pigs‚ although we might not like to think so. Since we have a good deal in common‚ it is very helpful for us to study these animals both anatomically and physiologically. We do this when we test medicines on pigs‚ perfect surgical procedures on pigs‚ and even when

Chemical Composition of Bone Bone is a very hard material which is capable of bearing a large amount of weight and resisting tension and twisting forces. Therefore‚ this material is both flexible and hard. The hardness of bone is due to calcium deposits in the matrix while the flexibility comes from the organic material of the matrix. We can illustrate these facts by treating two bone samples by two different methods: 1. Soaking a bone in vinegar (dilute acetic acid) removes calcium

Preparing for Dissection The first thing to do when preparing to dissect a shark is to get a pair of gloves so the smell of shark and the raw shark is not touched and on whoever will be dissecting. The next thing to do is get all of the materials that will be needed while dissecting the shark. The things that will be needed are: scalpel‚ tweezers‚ prop‚ pickups‚ scissors‚ and a tube to put the shark in. Then of course the last thing needed before beginning the dissection is the shark.

For my final project in Zoology I choose to write about the Starfish and Mussels we dissected. I chose these because‚ for me‚ these dissections were the most fun! Seeing what was inside of the starfish was nothing I had thought it would be‚ and the mussel is something I eat but usually it is mostly cleaned out by then so it was interesting to see what it looked like before it was cooked. As well as dissecting these animals‚ I was able to learn about how they interact with one another. In this essay

Dissection is a common practice among high schools in the biology class. With new technology arising‚ there has been many debates that have been presented looking at the pros and cons of such behaviour. Millions of animals are killed annually‚ there are little to no control measures in place‚ and animals suffer for the use of dissection among students. In the United States‚ six million frogs are dissected annually in high schools. An additional amount is used in elementary and universities across

COW EYE DISSECTION Use the following link to watch a video on a cow’s eye dissection. http://www.exploratorium.edu/learning_studio/cow_eye/video_sm_all.html Aim: The purpose for a cow’s eye dissection is to learn the different parts of the eye by doing a hands on experiment. You can always see the eye from images or diagrams‚ but this experiment helps you get a better visual and feel of an eye. Materials: * Scalpel * Scissors * Newspaper * Cows eye Method: 1. Examine

Sleep and Counting Sheep Matthew S Corman Bethany College Abstract This paper is a summary of two handouts that test our sleep habits and determine if the amount of sleep is enough for our needs. These explanations are all pulled from personal experience and our book Exploring Psychology by David Myers. There are several theories used in this paper that are unproven but are supported by many researchers as credible. Sleep protects theory suggests that through many years of our species the

My mother has taught us never to accept payment for a kindness." He said‚ "Then I thank you from my heart."
