Science Chicken Dissection

On Friday October 6th, I dissected a chicken wing with my partner Lin. We were supposed to look for things like the cartilage, bone, muscles, shoulder joints, tendons, ligaments, etc.

The components that contract to move the wings are shoulder joints, the elbow joints, biceps and triceps. The surface of the bones and cartilage were kind of smooth and hard.

The chicken wing functions like this. The tendons and ligaments hold the bones and muscles together. The cartilage connects the bones, which prevents damage and friction between bones. To move, the bicep muscles stretch and the tricep muscles tighten and contract, which move the elbow and rest of the wing.

Chickens have a humerus, radius and ulna like humans do.The chicken wing bends the same way as the human arm. The shoulder joints were ball and sockets, just like ours. However, chickens have more skin and surface area around their arms because they have feathers, while humans don’t. Chickens, like other birds have hollow bones, which allows them lift off the ground. Humans have more muscles and fingers, (opposable thumbs) which allows us to lift objects easier.

 

Superfood Public Service Announcement

Superfoods – Quinoa

A superfood is a food which usually, is rich in the nutrients your body needs to survive. Many foods have the label of superfood, and they are usually more expensive and desired over regular food. The superfood I decided to research is quinoa, a type of rice-like grain. There are 3 mains types of quinoa, (white, red and brown) but there are roughly 120 types that can be identified.

Quinoa, mostly contains protein, a nutrient that strengthens and repairs our body’s tissue and muscle. Having all 9 necessary amino acids (a valuable part of protein) quinoa is constantly growing in demand worldwide. In a serving of 185g, quinoa mostly has water (135g) since it is absorbed when cooked. It also has 8.14g of protein and 39.41g of carbohydrates. Although there are more carbohydrates than protein, having amino acids increases the protein’s value. An average woman needs 46 grams of protein a day, and a man needs around 50.

I decided to compare quinoa to yogurt after searching for foods with high protein value. Yogurt was one of the foods with a large protein amount in a 185g cup, the same amount of quinoa I was comparing. Unexpectedly, yogurt has more protein than quinoa. Regular vanilla yogurt in a 185g cup has 17.32g of protein.

Seeing as quinoa has less protein than a regular cup of yogurt, there are some issues with calling it a superfood, mainly revolving around money and morality. Superfoods are supposed to be full of nutrients we need, so why not call yogurt a superfood? Quinoa is 1,600 yen on sale at Costco. That is equivalent to 16 U.S dollars, whereas yogurt can be bought in a 16 cup bunch for around 800 yen. Also, calling quinoa a superfood is tricking a large amount of people into buying a food with nutrients they already consume daily for breakfast. It’s not right or fair to create that illusion surrounding quinoa. Eating regular vanilla yogurt mixed with a simple breakfast cereal gives you the same amount of nutrients since cereal contains a lot of carbohydrates. By consuming the nutrients this way, money is saved and it takes very little time to make.

In conclusion, the term superfood appears to be extremely flexible, and you shouldn’t automatically believe that a food is super until further research has been done. Superfoods aren’t always super.

Child Labor Trial – Persuasive Paragraph and Biography

A Brief Biography of James Hardy:
Written by: Sophia Pichardo and Koumae Adams

James Hardy is a factory owner that produced textiles. He is fully against the use of underaged children in factories; a term that’s called child labor. James Hardy was born in Winchester into a wealthy family. His grandfather owned a factory. He helped with the machines and learned how to run a it at young age. His grandfather later died by illness, and James inherited the factory at age of 27. He tries to run his factory in a morally honest and fair way, but unfortunately, child labor in the 1700’s – 1800’s is almost inevitable and hard to avoid. Instead of overworking and using the children as slaves, he compromised and only hired 14-15 year olds and up, reducing their work hours by many and providing safe and hospitable environments for them to rest, work and live in. It is proven that workers who have fewer hours can produce more content, which leads to better economical production. To keep his business blooming at competitive prices, he tried to convince other factory owners to follow his example of how he treated his employees, similar to John Wood. James Hardy has improved the lives of many kids who would have suffered through unjust employment.

Persuasive Paragraph:

Child labor is morally wrong and should not be accepted under any circumstances. Children who work in factories for 12-15 hours a day are unhealthy and can develop very severe issues, both mentally and physically as a result.
Children should keep their innocent childhoods alive and should avoid going to factories and enduring harsh punishments and environments. Most of the children who went through child labor had to deal with cruel punishments, painful injuries, and many others. In conclusion, child labor isn’t smiled upon and should be stopped.

Industrial Revolution

What was the most important aspect of the Industrial Revolution?

Coal extraction was the most important part of the Industrial
Revolution, and without it, life today would not be the same. Without the extraction of coal, things like steam engines, machines, iron, and metal devices would not be present and active in modern time. Coal extraction changed the way materials were produced and delivered by powering machines and transportation to efficiently finish the job. Industrial production would still be developing if coal extraction wasn’t used as a tool to help polish and improve the way the systems worked. Agricultural produce was transported to the city or the industries by trains/the railways which are made from iron smelting, that run on steam power, which would not be possible without coal extraction. It’s all a system that connects and at times there are doubts on what started it all, but without coal extraction, most of the major aspects of the Industrial Revolution could not exist.
