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.

I&S Connection Reflection

In this unit, we focused on the Industrial Revolution and its effects on our current world.

How would your learning experience have been different if you’d done it in a different country?

I think if I was back in Bangladesh, this unit would have gone down a completely different road. I say this because Bangladesh is still a developing country that is struggling with its systems and control over itself. Child labor in Bangladesh is still an immense issue and isn’t going to stop any time soon because of the rocketing poverty rates and growing population. Our school was very small and was barely an international school, with most of it made up of natives. Constantly talking about the issue of child labor and its problems would be talking about outside of the safe walls of school. People lived in slums and huts everywhere. I think it would have been harder to finish the unit because of the harsh reality the country is still living through. I don’t think I would have been as free to express my thoughts and beliefs as I am here, because I would always be frowned upon for disrespecting or stating the issues with their country.

What are you studying in another subject that is connected to this?

In English we learned about persuasive language and how to use it effectively. It think that helped us in this unit because in our summative, we were trying to persuade the judge (Ms.Madrid) into agreeing with our side of the argument. I think it gave us a stronger chance to be on the winning side of the debate. Another connection with school is in music. In music we are learning about blues music and its deep history. It was a way for poorer people and slaves to have a safe way to emote without getting into trouble. I think that relates to the Industrial Revolution because there were many people going through poverty and rough times because of the sudden change in the environment and people.

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.

Empathy Map:

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.

Drama Puppetry – Lee Randall

In drama class we had a workshop on puppetry with Lee Randall. I learned many things from him and how to use a puppet correctly so that the audience would fully believe and understand that it was alive.

I learned that the most important part of a puppet is its eyes because they draw the most focus. You need to make it move with a purpose.  The person who is in charge of this movement is the person controlling the puppet’s head because they are in control of its eyes and where it is looking. Another key thing to remember is to show exaggerated breathing or deep breaths.

In drama and other subjects we did things that helped us in this workshop. Like in P.E, we used levels in our dance unit and you need to use levels with a puppet and show its weight. Also, earlier in drama, we worked in pairs and one of us was the puppet, making it slightly easier to know how to manipulate and help express feelings and a story from it.


Materials in YIS Technology

There are many different minerals and materials in the technology today. Each has a different purpose and can be in different electronics. Today I will be focusing on the materials in an iPhone.

Identifying elements and compounds used: 

There are numerous materials in iPhones, and I’ll mainly be talking about three. Those three are: terbium, lanthanum, and praseodymium. They work in similar parts in the phone.

Terbium is an element used in an iPhone. Its symbol on the periodic table is (Tb) and its atomic number is 65. It is mostly found in the phone’s colored screen and vibration unit. It can be a very good alloy of dysprosium and iron, which helps move a magnetic field which is why its found and used in speakers.

Another element in an iPhone is praseodymium. Its symbol on the periodic table is (Pr) and its atomic number is 59. Praseodymium is used in the phone circuitry, the coloured screen and speakers. They use it in the color screen because it produces arc lighting and gives glass a gentle tint, which is the screen of a phone.

Lanthanum is also used in iPhones. Its symbol on the periodic table is (La) and its atomic number is 57. It is mainly in the phone circuitry and the color screen. It serves in other products such as lamps, projectors and studio lights because of its many catalytic applications and accompaniment with glass. Which basically means it can conduct a big amount of electricity and make the rate of chemical reactions faster without going through any major change in chemicals.


There are a few issues that surround lanthanum. It is a very rare and has to be mined with great care. It tarnishes quickly when exposed to air and could cause health risks if exposed to it for too long. It is found in monazite and bastnäsite ore, which is mostly mined in China, (the statistics are very high with just under 100%) it is sold at a very high price because of its importance in the electronic and automobile companies and industries. There used to be multiple mines in different countries, but these were shut down in 2002 because of environmental issues, therefore greatly limiting the supply. Because of its rarity, it costs companies and governments a lot when phones are just thrown away or never used because of customers newfound attractions to the newer models. With all the recent technology and products, old ones are being wasted, which in turn, wastes the minerals in them.


I think that we should raise awareness on how to recycle phones to help conserve and sustain the minerals used in them. It doesn’t matter how, we could make posters, share articles on social media, talk about it, create an after school activity or service group. However you want to help, just talking about it can make a difference. Recycling phones is a truly helpful idea that is present in many communities and countries. Older phones can be utilized by charity groups who serve underprivileged families, senior citizens, or victims of domestic violence. These individuals would not have the means to communicate without charitable organizations, and we preserve the life span of the technology and the resources within them.  We should also use phones to their full extent, because many phones are just neglected once a newer version comes out. Constantly buying new phones when the old ones still work is foolish, because then the issues just come around full circle. Even phones that are damaged or non-functioning can be sent back to the manufacturer and working parts can be salvaged to refurbish damaged phones. This prevents perfectly good minerals from being cast away. Saving one phone can go a long way, and if we get groups of people to each recycle at least one phone, imagine the positive affect it can have on the mining industries.
