Research Report on Greek God

Currently, in Literacy essential class, we’re learning about Ancient Civilization; as in history while learning literature as well. The historical contents that we’re focusing on are The First Civilizations, Ancient Egypt and African societies, Ancient Greece, Ancient Rome and Roman Empire and World Religions. The literacy skills that we are going to get out of this unit are:

  1. Citing textual evidence from informative text
  2. Writing and responding about informative texts
  3. Independent research project on an aspect of culture  from an ancient civilization
  4. Rhetorical arrangement and language of informative texts
  5. Mini-grammar lessons using unit texts
  6. Vocabulary Decoding and Discovery

 

For the past weeks of this unit, we have been doing a Greek Mythology Layered Project as our final product. One of the project was to write a research report on one of the 12 Greek Olympian gods and goddesses. I have randomly assigned to research on Apollo, the god of light and music. In the report, we are assigned to write 7-paragraph informational report on the god that we are assigned.

Here is the report that I wrote for the god, Apollo.

 

Apollo is one of the most complex and important gods in Greek mythology, and is the god of many things, including: music, art oracles, archery, medicine, sun, plague, light and knowledge. He is the son of Zeus and the Tita Leto, and was born in Greek island of Delos along with his older twin sister Artemis – goddess of the hunt. Apollo is a wise god and his myths describe him as a cheerful and light-hearted individual. Since Apollo was a musical talent filled with poetic words; as poems are often set to music, he was considered as the god of Music and Poetry.

The lyre which is perhaps his most well-known symbol signifying that he is the god of music. Another role Apollo had in Greek myth was to bring the sun to earth each day. According to the Greek myth, each morning Apollo rides a golden flaming chariot across the sky bringing daylight to the world. In the evening his twin, Artemis, rides her own chariot across the sky bringing darkness. He also considered as the god of healing and medicine, either through himself or through his son Asclepius. He could also bring disease and plague with his arrows; the god that can cause disease is also able to prevent it. In addition to that, Apollo taught men the art of medicine, so he is often referred to as “The Healer.” Predominantly, Apollo is alternately referred to as the God of Light and the God of Truth and because of his truthfulness and integrity, he was granted the gift of prophecy and oracles, meaning that he could look into the future but it wasn’t always a guarantee.

 

Apollo has his father and mother Zeus, the king of Gods and the Titaness Leto on the Greek island of Delos, conceived during Zeus’s marriage to Hera; his twin sister Artimis and his half sister Eilityia, Eris, Hebe, and Perseophone, but that is not half of Apollo’s family.  He also has his half brothers, Ares, Dinoysus, Hephaestus, Hercules, and Herme. Apollo only has three cousins as well Arion, Desopena, and Trition. He also had paternal grandparents Cronus and Rhea along with his two wonderful great-grandparents Ouranos and Gaea. Apollo was not lucky in love. His first love was Daphne, and Eros, the god of sexual attraction caused problem with this relationship. Eros shot a golden love arrow into Apollo’s heart, and an anti-love one into Daphne’s. Apollo passionately chased after Daphne but she was scared so she prayed to her father, Peneus, the river god, for help; he turned her into a laurel tree. Apollo was truly still loved her, so he the made the laurel a sacred tree. Apollo also has a love affair for Cassandra, who he promised to give her the power of prophecy if she would comply with his desires. She accepted the proposal, received the gift, and then refused Apollo her favours and so Apollo took revenge on her by decreed that nobody would believe her. People believed that she was a madwoman. Apollo fell in love with another beautiful young woman who became pregnant with his child. Apollo assigned a white raven to spy on Cornonis, and the raven reported back that she was cheating on him. Apollo has Coronis killed and later regretted this act, but he luckily snatched the unborn child from her naming him Asclepius, who later became the god of healing and medicine. Apollo also suffered when he fell in love with a man, Hyacinth, son of the Kind of Sparta. Greek man of this time period had open gay relationships; one day they had a discus throwing match, and Apollo accidently killed Hyacinth in such tragedy. Apollo did not marry anybody, but Apollo was a bisexual person. He slept with a lot of men just for the pleasure of it but he did have four kids, Asclepius, Troilus, Aristaeus, Orpheus, even though he wasn’t married.

 

Apollo’s mother, Leto, was the goddess of motherhood. She seduced Zeus and became pregnant with twins, but Hera was furious over the affair and made sure that Leto was unable to find a shelter to give birth. Hera even kept her own daughter, Eileithyia, from helping Leto give birth, as she was the goddess of childbirth. Zeus felt terrible for the pain and suffering Leto was going through; out of pity for Leto, Zeus turned her into a quail so she could safely give birth to their children. Leto searched all over Greece until she found a small island known as Delos. Hera was unable to stop Leto from settling on the island as it was being blown by the wind and moved by the waves. Leto suffered for nine days and nine nights with terrible labor pains. On the tenth day, she went to a small lake and leaned up against a palm tree. She gave birth alone ot Artemis who would become the Greek goddess of the hunt. But Artemis immediately took on a new role and assisted her mother in the birth of her brother Apollo. He was fed on nectar and ambrosia and quickly grew to manhood.

 

There are only a few descriptions of Apollo in literature that we can form an imagination to give us a good idea of what he looked like. In artistic representations of the god, he is always depicted as the ideal of kouros, which mean a young, athletic and a physically handsome man with golden hair and beardless; with a crown of laurel wreath of his head. There are many symbols associated with Apollo, including his silver bow and arrows represent the myth where he defeated the monster Phython. Apollo is also the god of plagues and is known for shooting plague arrows at the enemy during the Trojan war. The lyre which is perhaps his most well-known symbol signifying that he is the god of music. In the ancient myths the god Hermes gifted Apollo the lyre in exchange for the rod of health. Apollo’s lyre has the power to cause things like stones to become musical instruments.

The raven is a symbol of Apollo’s anger. At one time the raven was a white bird but after delivering bad news to the god he turned all ravens black. The bird had the bad news of having to let Apollo know his lover Coronis was being unfaithful. The rays of light that radiate from his head along with the wreath he wears are both meant to symbolize that he is the god of the sun. Lastly, the branch of laurels was actually something Apollo wore as a sign of his love for the demigod Daphne.

 

There was a temple built in Apollo’s honor, it was often filled with people who were hoping to beg Apollo to use his gifts, particularly to help foretell their futures. But some said there were two reasons why people came to Apollo’s temple, to consult with his oracle, and to be purified after commiting a crime. Apollo’s sanctuary was where the Oracle Delphi dwelt. Oracle of Delphi is his assistant who help with the prophetic side of his nature, who could foretell the future. This temple was known to be the center of the entire world. It was a spot where Apollo offered advice and wisdom to those who seek through the oracle. The importance of this temple in the ancient world was as a place of guaranteed peace, where leaders from all over the known world – representatives of the Greek city-states, Cretans, Macedonians and even Persians – could come together, even if they were warring elsewhere, to celebrate the Pythian Games (one of the four Panhellenic Games of Ancient Greece), to make offerings and consult the Oracle.

 

There is a myth teeling Apollo became known as the god of music. It begins by describing a Python who lived on Mount Parnassus, he is lethal, killing anyone who crossed him. Four days, after Apollo born, he was strong and able. He had been given a silver bow with golden arrows for the blacksmith Hephaestus. Apollo wanted to seek revenge on Python for every he had done to the Greeks, including chasing his mother while she was pregnant. Apollo went to the Phython’s cave and shot an arrow at the Python and it pierced him in the forehead. The Python screamed in pain so loudly that all Greece heard it, but he couldn’t save himself but succumbed to his jury. Apollo celebrated his victory by playing a song using his lyre for everyone to hear. The song was so perfect that it earned him the title of god of music.

 

Although Apollo was Zeus’s favorite son, and next to Zeus, the most important god, he personally has some lack of emotional depth. Apollo is not aware that anything besides thought can give life meaning. He need to live in the moment, feel sensations, explore his feeling, and have outer experiences like Dionysus. It would be easy to do this through music and dance, as Apollo has already achieved his expertise. He must learn to follow his heart, and move beyond the boundaries of his thinking world. After all, Apollo is still one of the powerful 12 Olympian gods. Follow by his forename, Phoebus, means “bright” or “pure” and connects him to his grandmother, the Titan Phoebe. He served many roles in mythology such as bringing the sun to each new day, predicting the future, and he was also the god of music, and healing. Like all gods, he certainly led a colorful existence.

Cecilia Payne-Gaposchkin – Women in STEM Research

Cecilia Payne-Gaposchkin, original name in full Cecilia Helena Payne, (born May 10, 1900, Wendover, Eng.—died Dec. 7, 1979, Cambridge, Mass., U.S.) was a British-American astronomer and astrophysicist who found the explanation for the composition of stars in terms of the relative abundance of hydrogen and helium.

 

She began her scientific career with a scholarship to Cambridge University, where she took the course in physics and was inspired by a lecture on how solar eclipse relate to Einstein’s Theory of General Relativity, which gave her the passion for learning and science on physics and astronomy.

Unfortunately, Cambridge did not have a lot of opportunities for women and did not offer them advanced degree. So, she moved to Massachusetts and pursued a doctoral degree in astronomy and started a fellowship at Harvard College Observatory after meeting Harlow Shapley, and American scientist and the head of the Harvard College Observatory.

 

She began her astronomy work by calculating the abundance of chemical elements from stellar spectra and her 1925 thesis, entitled Stellar Atmospheres, was famously described by astronomer Otto Struve as “the most brilliant PhD thesis ever written in astronomy.”

 

When Cecilia Payne began her study of stellar spectra, scientists believed that the relative abundance of elements in the atmospheres of the Sun and the stars was similar to that in Earth’s crust, briefly mean that the star were built like the Earth; but Cecilia proved them wrong.

 

Cecilia had a better knowledge of atomic spectra than most astronomers at the time. She knew that the extremely hot sun would cause atoms to ionize. She used the equation of an equilibrium of physicist Meghnad Saha on the ionization of atoms to prove that different ionization states would show up as different absorption lines -light frequency-  on the stellar spectra, figuring out how many electrons the atoms had and the elements to which these ions could belong.

 

She then discovered that the sun is made mostly of the hydrogen and helium and she found similar results to other stars. Cecilia came into conclusion that, unlike on Earth, hydrogen and helium are the dominant elements of the Sun and stars; confirmed to the fraction elements in Milky Way Galaxy that 74% is hydrogen, 24% is helium and the 2% left are all the remaining elements – which proven that Cecilia’s result was right.

 

Henry Norris Russell, an American astronomer strongly opposed to this conclusion and told her it was “impossible”, but many other astronomers and the scientific community  has read her paper that was turned into a book, Stellar Atmosphere, and realized that she was totally truely correct.

 

Cecilia Payne made a long journey to prominence in a scientific community that resent to women. Besides, Cecilia accomplishments, being a women meant she was only recognized as a technical assistant who worked at Harvard with her husband, Sergel Gaposchkin. She faced many challenges and arguments within other female scientist who opposed her thesis.

Eventually, in 1956, Cecilia Payne-Gaposchkin, a pioneering astrophysicist and probably the most eminent woman astronomer of all time, became the first female professor in astronomy and her works has made a lot of people understand and discover something new about the universe for decades since she died in Cambridge, Massachusetts, on December 7, 1979.

How Boy Views on Girl’s Emotions

Boys, I have a question for you- what would you do and what would you feel if you saw a teenage girl crying in the corner of the room?

Emotions, really, are just like somewhat-well-integrated different personalities inside a person’s head, triggered by different stimuli – many external, some internal – that drive that person to different thoughts, decisions, actions, and behavior.

Everybody is emotional.

Based on the article written by HealthGuidance, there is a stereotype that girls are much more “emotional” than boys whereas “real man” do not cry or get upset. Unfortunately, society has told teenage boys it is a sign of weaknesses to express their feelings while it is much more socially acceptable for girls to talk about their feelings and focused on their emotions and refer to them more commonly.

 

“I would talk about my feelings only to my close friends,” said Sreyneang, a high school student from the Liger Leadership Academy. “but most of the time, I keep my emotions to myself.” She added, “And sometimes, If I can, I would express it out publicly.”

 

Teenage girls are more probable to talk about what they are thinking and feeling and to demonstrate with their tears, facial expressions, hand gestures, and body language.

 

By personal experience, crying has always been a healthy release and I were not ashamed to cry easily.

 

Compared to girls, boys often show their emotions to less people, and often only to their nearest and dearest. Boys tend to have a greater control over their emotions and what they will manifest to the world, possibly due to having more difficulty displaying emotion than girls.

 

Many times, they do not know exactly how they feel, so they try to figure it out on their own, inside their head.

 

“Yes, sometimes it’s hard for me to understand what I’m feeling.” states, Davith Chan a teenage boy student from Liger Leadership Academy.

 

Barton GoldSmith, a Ph.D Psychotherapist stated in his article that, “Most men and boys have a hard time communicating anything that remotely resembles an emotion — because emotions are scary to men, who think much more than they feel.”

 

Boys can not think and feel simultaneously, it is challenging for them to switch gears from their head out to their hearts.

 

“I can’t switch from heart to brain. It will literally distract my work if I think and feel at the same time.” Davith added.

Davith Chan was asked by a question, “Do you cry?”

 

He pauses a moment after hearing the question and finally said, “No,” he sighs. “Unlike others, crying isn’t a way to release my stress.”

 

A follow-up question was then asked, “Well, do you feel comfortable sharing your problems with other?”

 

“No,” he quickly spokeup. “I don’t want to share my feelings to other because I know they wouldn’t care about my problem. Depends on people, some of them might even judge my problem.” He sight with relief. “But I get stress sometimes when I keep all my problems to myself too much.”

 

Let’s switch some gear up. If you see a boy friend of yours, or any other random boys crying, what would you feel?

 

“I would think to myself ‘What happen to him?’ I’m curious for the reason.” Davith put his elbow on the table, palm to his forehead like he was in a thought process. “And I would feel pity for him, you know, no matter what happen. Because sometimes, I cry too.”

 

The same question was asked to Sreyneang, and she mentioned that it would be awkward for her to see a boy cry for some reason. “It would be weird.” She hesitated. “You know, boy don’t often cry, not that I’ve seen a lot at least.”

 

This goes back to where society view men as weak if they cry, and yet no one knew where the stigmas originally came from. Where Sreyneang said “boy don’t often cry,” who might have guessed that she heard it from her parents or friends or just random people.

 

There are a lot of fish in the sea, but you have such a bad luck that you hooked up with one who is emotionally unavailable. And here is an example of what Davith has said, “I’ve made people cry I have to admit that.” He said while nodding his head and gives me that guilty smile. “Like the other times, I made a girl and a boy cry. They were irking me and I was distracted by them and so I yell at them “Shut UP!” very loudly.

 

As Davith and I were in the middle of the conversation, David Phim, an addicted – teenage gamer boy, interrupted us and said, “Girls easy to get mad,” Davith and I both looked at him in amazement. “Oh! Sorry,” He apologize for interrupting, but I said it was okay and that he could join our conversation.

“[Like I said], girls get mad so easily in general that I[‘ve] experience. Like SOME girls!” David continued with his speech.

 

According to Thought Catalog article, some of the guys think that girls emotions are crazy and punishing to understand. For example if you are in a relationship: boys see themself as a victim and girls as their attacker; for instance, where girls always get jealous towards other girls and guys for the fact that she have “insecurities”. Boys might also think girls cry far too often, but there’s always a reason, even if it is slightly irrational. This is when girls use the PMS (Premenstrual syndrome) excuse, even if they know, they don’t have it.

 

It is so difficult being a woman, don’t you think so? You are constantly having some inner battles either with your emotions or with guys.

 

At this point, Davith joined the discussion again and utters, “Girls cry more because of relationship.” And David, in the other hand, peered at me with a smile on his lips. “Girls have more stories to argue about.” Davith continued, “I don’t know why, but it’s so hard to understand [girls] sometimes.” He shrugged after finishing his sentence.

 

“Sometimes when I played with girls, [I would] just hit a bit and then [she would] cry.” David mumbled after Davith.

 

Written by HerWay article, in the topic of “15 Signs Of An Emotionally Unavailable Woman,” the introduction quoted, “It is true that guys have so many problems in relationships with women because we are so complex. There is that saying that men are from Mars and women are from Venus. I think this is true because we definitely don’t think in the same way and we don’t express our feelings in the same way either. Sometimes it is just that obvious that we come from two different planets.”

 

Moreover, David mentioned, “If couple breakup, boy [would just be] upset [and then] walk away, [but] girl [would] cry and need someone to comfort [to make them feel less lonely]. And I’ve seen [the same thing happen] a lot with my roomates. Man like to stay alone.” He shrugged. “Girl need more caring.”

 

Davith was looking kind of confused and curious with what David just said. He looks like he wants to disagree with David. “Only for some girls, man, not all!” He finally indicated.

 

What David mentioned is just another way of saying that girls are emotional and weak. Don’t you think being a teenage girl is very easily judge?

What would you do and what would you feel if you saw a teenage girl crying in the corner of the room?

 

“I would go and ask her why [she’s crying].” Davith said with no hesitation. “The same as [I would do to] anyone. [He/She] must have a reason of crying.”

 

“For me I would walk away.” David said while playing on his computer. “I [would feel] pity but I’m not brave enough to go and talk to her. I would let another girl help.”

Artificial Reef – Year Long Project

Last year, my partner, Venghour and I worked on a project together on an artificial reef designing. What inspired us to choose artificial reef as our project is that we want to protect our Cambodia ocean and involve in action that could possibly bring back the existence of marine life. And we did it! In this project, we have designed two type of artificial reef, one of them has been deployed in Koh Seh, Kep for a year now, and the other one is going to get deployed very soon. We have been monitoring our small reef and we see that it has created some impacts that we’re really proud of. Even though it’s not as big of an impact, but we’re starting from small and slowly growing into reaching our goals. We’ve worked really hard to research, design, deployed, monitored and finally we have written a report on this project.

Click here to read our report on Artificial Reef in Cambodia Project 

Despite the fact that it was a year-long project from last year, we’re not going to stop in the middle of the journey. We’re both going to continue this project with the benefits of being in the Liger Marine Research Team so we could do a deeper scientific monitoring by collecting data and possibly, those data will encourage us to do more studies out of it. 

An updated picture of my artificial reef!

The director of Marine Conservation Cambodia (MCC) posted this video on our artificial reef that was deployed at their site

“So we have a total of 6 structures, placed in different test locations within our 150mx300m area, Under the Pier, close to the reef, and further out. This is a small structure created by the Art Team and deployed together with the Liger Learning Students around 2 months ago. As you can see it is already providing shelter and these artificial habitats give a place for fish to lay their eggs and a place were very small fish fry can develop safely into juveniles and in turn to large adult fish. Creating Habitats and Restoring Keps Ocean. One Step at a time.”

Macroeconomic are fascinating!!

In this expertise, we explore macroeconomics which is a bigger concept to economics. We studied many ideas and notions and the most common that talked a lot about is GDP and GNP. While we were learning about those concepts, we also discussed advanced and logic questions that people around the world are questioning. Personally, I really love learning about economics but it is a very hard concept to understand sometimes. I’m very fascinated with the world especially the relationships between countries or regions and by learning about macroeconomics, it has helped me understand a small fraction of it but still got me curious.

Here is the note I took in class period: Macroeconomics Note – Soliday

White Building Exploration

This is the first exploration of the 6th year at Liger Leadership Academy. In this exploration, we studied the history of the white building from the past, present and future. In addition we were also learning about the development of Cambodia since it’s one of the major effect to the White Building itself, but also other iconic building in Phnom Penh. The White Building is the work of a Cambodian arcitect, Lu Ban Hap and a Russian engeerer, Vladimir Bodiansky, built in 1963. The building was a part of the Bassac Riverfront complex, an urban development designed by famous Khmer architect Vann Molyvann. This building has survived the genocide and people, specifically the artists has moved in, given the apartment by the Ministry of Culture. Recently, the residents has been evicted from the building because the goverment worried about the safety of the people their since the building is very old and it also touched on the beauty of the city as the building located in the central of Phnom Penh.

 

Besides the studies, our group of nine students worked on individual project that described what we have learned in this exploration. I’ve made a 20 minutes documentary, showing the aftermath of the building since it has knocked down. The video included many interviews with the residents, the goverment and the company, most importantly how the company and the residents agreed upon the compensate.

 

Personal Reflection:

 

After studying about the White Building, I started to understand more about the development of Phnom Penh, both in the past and in the future. I first thought that this exploration will be learning about the architecture of this old building but it’s way more interesting than the expectation. I really enjoyed learning and investigating this topic.


The building itself is not just a building, bricks walls and roofs for building, it’s more full of life. It’s amazing to see how this old, historical building connected to the development of the city of Phnom Penh as a whole. There’s also a lot of stigma about this place but after hearing different perspectives from all parts of people, there is more than one truth to this.

 

When I listen to the company and the government perspective, I think that the residents are happy with their decisions and the compensation. But then I realize I don’t like the idea of knocking down the building. Yes, the building is old but it would be a great place for a historic location so that other people can study about it too. But then I also think that, if the building was still there, it wouldn’t make the city look great too. There are a lot of positive and negative affect to this and it is very hard to make a statement to it.

 

The sad thing about this White Building that always struck me is the separation of the “community”. It is sad to see a whole cheerful, happiness and joyful group of people to be apart from each other, especially the artist’s community. After the war end, artists were brought back together so that they can bring back our cultures, and now they’re all separated. It’s just like the war has started again and our one piece of arts is starting to fade. Even Though it is just one piece, but it can make up a hole and if that one piece is missing, it can’t create a whole anymore.

 

I feel like development these days have been creating a lot of effects and influences to people who are living in the city. People have been evicted from their home so that developments can happen. But where do those people go? Yes, I agree that some building are built for apartments and housing. But still, I can see that apartments in Phnom Penh aren’t really affordable, so how can people find a place to live that they can afford? And since a lot of people want to live in the city? Because most Cambodian people aren’t that rich to have a luxury place to stay. Also, those who are rich are going to be rich, those who are poor will always be poor. It’s fascinating to see development happen in Cambodia, but how can we do business but also make people happy at the same time?

Hip Hop

For the last seven weeks, I have been learning Hip Hop with my teacher Sam. Hip Hop has always been my favorite dance because last year, my best friend and I have been learning Hip Hop by our own and learn dance styles from Youtube. This year, I’m very happy that we can have an actual professional dance teacher to train us. So far, we have learned some short dances from many songs.

  • Crying in the club
  • I wanna dance with somebody
  • Despacito

Videos of the dances are coming soon.. Stay tuned!

This is a video of a dance with my best friend last year!

AP Statistics is HARD!

This year in math class, I have taken and accept the challenge to learn not just something new but something that is above my level. For this past few months, I’ve been taking an AP course, AP Statistics which is a college level course, provided by the college board. The resources that we use to help us with our deeper understanding in this course are two textbooks and many online resources provided by our teacher, Jeff. The two textbooks are The Practice Of Statistics, and the Barron’s AP Statistics book, and most of the concepts that we learned are mainly from The Practice Of Statistics textbook. I have to be honest, this course has been very challenging for me even though I have put double effort into this, both in class and outside of class. So far, I have got to chapter 4 which talks about the two-way table data and categorical data. It is quickly starting to get more challenging as we move on.

Course Details

The purpose of this course is to introduce students to the major concepts and tools for collecting, analyzing, and drawing conclusions from data. Students are exposed to four broad conceptual themes:

  • Exploring Data: Describing patterns and departures from patterns
  • Sampling and Experimentation: Planning and conducting a study
  • Anticipating Patterns: Exploring random phenomena using probability and simulation
  • Statistical Inference: Estimating population parameters and testing hypotheses

Khmer – Writing a Formal Speech

Being a good public speaker is not easy, there are a lot of learning, preparation and writing have to be done before hands. Making a formal speech in Cambodia is very tough since the speech has to respect the structure of the culture and the ranking of the audiences. We can’t just say hello and start the speech, it a lot more protocol that we have to follow to make our speech become eligible. Since our Khmer learning facilitator saw that everyone is not good at doing this, he made us write a formal speech with an intention of conveying an idea. For the introduction of the speech, we had to respect and greet line by line from the highest respected person to the guest.

Physics – Forces Concept and “Coefficient Of Static Friction” Lab

In physics class for this first term of essential, we learned a lot about the concepts from resources and study deeply through different types of problems. These few months, we have studied about forces, friction, static equilibrium, inclined plane and other concepts that related to forces which is what we’re studying in physics currently. Last week, we had our first experimental class in a long time in which we’re doing lab about the inclined plane. The purpose of this lab is to experimentally determine the coefficient of static friction for multiple materials and to solidify students’ understanding of friction.
So what we do is Build a ramp using the plank of a wood place different materials (paper clip, sandpaper, cloth) upon the plank of wood and determine the minimum angle at which the material will slide. We did three trials of this process, and take the average of the three angles we measure. By using the average minimum angle we find for each material to calculate the coefficient of static friction. And then we compare the results to the other group, which turned out to be quite different.

Here is the data for my group.

After we take a look at the data we made a short report by answering some questions about what was happening while we were doing the lab.

Assumption
Box position: In the experiment, for each trial, we change the position of the box to see the difference. At last, we take the average of it. Its stay in different position and to take the average of it is just not that accurate.
Sandpaper 3: We make the assumption about Sandpaper 3 that it will have the most coefficient of static friction the object is rougher than other objects.

Real-life Factor
Surface of the box: each time we do the experiment, the surface of the box keeps getting smoother that been scratch by different sandpapers, cloth and wood.
