Science – Heart Dissection

This blog post will be about sharing my experience with a recent experiment that we just had last week on Friday. The experiment that we were able to do last Friday was dissecting a sheep’s heart and discovering what some part of a heart looks like and feels like in real life.

For this experiment to be successful, here are the list of equipment that we used in this experiment:

  • 1 Scalpel
  • 1 Scissor
  • Tray
  • 2 Gloves
  • 1 Lab Coat
  • 2 Newspaper
  • 1 Tweezers

Method

The first step that we did was to (if you’re a girl) tie your hair so it wouldn’t be on your way during the experiment. We then had to be in groups of three or a pair. Afterwards, the teacher had us put on some lab coats in case some dried blood from the sheep’s heart gets on our clothes. The next step was to grab our equipments and properly set them up on our table. We were provided with 2 pieces of newspaper which we then spread out on our table—wide enough to cover the tray that was going above it. Once done, put your tray above the newspapers and grab your other equipments (scalpel, tweezers, scissor) and place them alongside your tray. After we gathered every piece of equipment that we needed as well as set them all properly, we were told to the heart in half and open them like a book. We then get to have a good look at what’s inside the heart as well as looking for which side is thicker.

Some part of a heart that we were able to see when we cut it open was the veins that were hard to break, vessels, ventricles, atriums and dried blood.

Here is a picture of the heart that we dissected that some parts that we were able to identify.

To add more facts to your knowledge, the right atrium is one of the four main chambers of your heart. It collects all the deoxygenated blood that has circulated through your body and prepares it to be sent to your lungs for a fresh supply of oxygen. Your left atrium is also one for the four main chambers of your heart. The difference between the atrium is that your left atrium serves as a holding room and a pump for blood that has oxygen returning from your lungs, preparing it to be distributed to the rest of your body. Another part of the chambers of your heart is the right ventricle. Their job is to pump oxygen-depleted blood (ones used from your body) into your lungs, where it drops off carbon dioxide and receives a fresh supply of oxygen. And lastly, your left ventricle. They receive the oxygen that had blood from your left atrium, and contracts forcefully to push that blood through the aortic valve and out to the rest of your body.

That’s all for this experiment, thank you for reading.

Effects of Heat

This term, our current focus is enhancing our knowledge about different movements of particles. I was able to learn 4 different movements of particles even though I was at ESOl for most of our Science lessons. Those movements are called: Conduction, Convection, Contraction and Diffusion. To help you understand more what those movements of particles define as, here is a brief explanation of what they mean and their differences:

Conduction is the transfer of heat or energy through a material by direct contact. For example, if you put a metal spoon in a hot cup of coffee, the heat travels through the spoon from the hot end to the cooler handle. That heat transfer is conduction. 

Contraction is when energy is removed (colder) or when two different temperatures make contact, particles move slower—causing solids, liquids, and gases to compress or get smaller. An example would be the contraction experiment we did that I will share soon. 

Diffusion is particles that are spread out from high concentration to low concentration units. Hot particles spread faster than cold particles because they have less concentration. 

Convection is the process of how liquids and gasses that rise and cold liquids and gases will sink; a circular movement called convection current. 

A brief vision of what our experiment of each concept consists of is for Convection, our experiment was to light up an empty tea bag and watch it rise up and fall down which the Convection was seen. For Diffusion, we were to compare if Potassium Permanganate diffuses faster on low temperature or high temperature. And lastly—because I was not there for the Conduction experiment—for Contraction, we were to make a soda can compressed or shrunk by dumping a hot soda can with hot water into a tub of cold water.

What I have learned from our Convection experiment was that there is a circular movement in Convection wherein when the particles reached their hottest temperature and became less dense, they will come up again—to move away from the heat source—where there is low temperature and go down again; this circular movement is called convection current. For our Diffusion experiment, what I have learned is that particles spread faster or have less concentration when they are in hot temperature and when they are in put in a cold temperature, they will still spread apart, though not as fast as particles do when they are in hot water. And lastly, what knowledge that our Contraction experiment gave me is that when the hot particles are stuck or can’t go anywhere then make direct contact with cold particles, they will move slower and shrunk or compress.

Out of all the experiments that I was able to do, my favourite one was the Contraction experiment. It is my favourite because it showcases Contraction very well which helped a lot to visualise what Contraction is and what it looks like. I like this experiment the best out of all that I was able to do because it’s the coolest, and most fun. This experiment also showed my class that following instructions when experimenting should be prioritised because if you don’t follow every part of the experiments method, you would not be able to do it right, not everyone would have the same results or just you will just simply fail to do the experiment correctly.

The contraction experiment that we did is called Imploding can. Our aim for this experiment is to visualise what contraction looks like and heighten our current knowledge about contraction. This experiment demonstrates contraction really well as well.

Hypothesis

I think that the soda can will compressed because the hot air will be stuck inside the soda can when it is dump into the cold water which will caused it to shrunk as the hot water makes contact with cold water causing the boiling air inside to be stuck.

For us to be able to be successful with this experiment, we will need some equipment. Those equipment are:

  • Gas Faucet
  • Empty soda can
  • Bunsen Burner
  • Heatproof mat
  • A stand
  • Gauze Mat
  • Bowl
  • Cold Water
  • Ice cubes
  • Thongs

Method

Our first step for this experiment was to set up the equipment that we gathered. What we did to make sure that our equipment was ready to go was to make sure that we have plugged the Bunsen burner into the gas faucet—make sure to have the opening air opened—put the stand over the heatproof mat with the gauze mat positioned above it, and make sure to put the empty soda can at the very top of everything. Once positioned at the very top, fill the empty soda can with water until you’ve filled it 100ml. And lastly, fill your bowl up to 70% or 60% water then put approximately less than six ice cubes in it.

Once everything is set up and ready, open your gas faucet—make sure the colour of your fire is blue and not red or orange. The moment before the exciting part, you need to wait for approximately 10 minutes or more until the water inside the empty soda can is boiling.

Result

When the soda can is finally boiling, turn off your gas faucet and grab your thongs; slowly with two hands, grab the boiling soda can with your thongs and quickly dump it—with the hole facing towards the water—into the bowl of cold water. That moment where the soda can compressed and shrunk quickly,  is the moment where it showed us what contraction is.

Discussion

Some of my classmates’ experiment did not work because they did not quickly dump the soda can once away from the heat source which caused the hot particles to be able to get out of the soda can before making contact with the cold particles in the bowl or the water was just not boiled enough so they were not that hot for the contraction to work.

The soda can compressed and shrunk because when the boiling water and hot can were immediately dumped into the cold water where there are cold particles, the hot particles or hot air inside the soda can can’t go anywhere which caused for both hot and cold particles to mixed and have less energy and which caused them to shrunk and go close together.

Conclusion 

Therefore, I think my group’s experiment for this focus was successful on the first try because we were able to follow each and every step we were given and we did not rush the waiting time. We also made sure that while waiting, everything is still going perfectly. The following instructions also made my hypothesis and the result of the experiment accurate because what I thought would happen, did happen because we followed everything correctly.

Thank you for reading.

Contraction Experiment

Today for Science, we did a fun contraction experiment. This experiment is about learning, understanding and visualising what or how contraction works. For this contraction experiment, the material we used was a gas faucet, an empty can, Bunsen burner, a heatproof mat, a stand, gauze mat, and a tub of water.

To help you understand what we did, here is a brief video explaining the experiment and giving you guys a visual of the experiment.

Contraction Experiment

The result of the experiment was that the soda can shrunk when the hot water and hot can were quickly dumped into the cold water. Why? the soda can be compressed to each other because when the soda can (which has hot particles) was quickly dumped into the tub of water where there are cold particles, the temperature inside the soda can can’t go anywhere which caused for both particles to mixed and have less energy which caused them to shrunk and go close together.

Hauora – Shark Infested Custard (Hula Hoops)

What is Te Whare Tapa Wha?

Te Whare Tapa Wha is a prominent Maori health model representing well-being as a four-sided wharenui. The areas of Hauora are Taha Tinana which means Physical, Taha Wairua that means spiritual, Taha Hinengaro which means Mental and Emotional, and Taha Whanau that means Social.

What activity did we do?

Today for health, we played another game. The main focus of our todays game is hula hoops. Hula hoops are used because the purpose of the game is to get from the start line to the finish line using hula hoops. For this game, we have to be in a group of five and are given four hula hoops. Fortunately, we were able to get big hula hoops. The strategy that my group thought of was to have someone lay out the hula hoops then the rest of the members follow behind.

How was hauora impacted by playing this game? 

I think my Taha Tinana and Taha Whanau is impacted by playing this game because this game requires moving parts of my body to move the hula hoops and this game also requires socialising with other people as it is a 4 people activity.

What is important to know or understand when participating with others? 

Something that is important to know when participating with others is communication and not be selfish and just play the game just by yourself.

Hauora – Marshmallow Towers

What is Te Whare Tapa Wha?

Te Whare Tapa Wha is a prominent Maori health model representing well-being as a four-sided wharenui. The areas of Hauora are Taha Tinana which means Physical, Taha Wairua that means spiritual, Taha Hinengaro which means Mental and Emotional, and Taha Whanau that means Social.

What activity did we do?

For health, we played another game today. This game is called Marshmallow Towers. We have to play this game in pairs and my pair was Jamillah. We were given a bowl for all of our equipment, 8 sticks, and 12 pieces of marshmallows. The context of this game is we have to try and build the highest tower amongst all of the groups in my class using only marshmallows and sticks. For them to stack and fall, you need to put the marshmallow between the sticks that you stacked properly and they need to be stable.

How was hauora impacted by playing this game? 

For me, this game showcases the Taha Tinana, Taha Whanau, and Taha Hinengaro. I think this game showcases those because you use Taha Tinana (physical) because you use your hands to try and stack the marshmallow and sticks together, Taha Whanau (social) because I socialize with other people as it is a pair game, and lastly, Taha Hinengaro (mental and emotional) because you need to think properly about the strategy that you’re going to use for them to stack properly.

What is important to know or understand when participating with others? 

I think that what is important when participating with other is to not be selfish and just play or do them just by yourself. It’s important that you also let them have a try of the game so they could enjoy it as well.

Health – Water Pong blog

What is Te Whare Tapa Wha?

Te Whare Tapa Wha is a prominent Maori health model representing well-being as a four-sided wharenui. The areas of Hauora are Taha Tinana which means Physical, Taha Wairua that means spiritual, Taha Hinengaro which means Mental and Emotional, and Taha Whanau that means Social.

What’s our activity?

Today, for Health we had a game named Water Pong. It’s a game that showcases the Taha Tinana in Te Whare Tapa Wha. This game showcases Taha tinana because it’s a game that moves your muscles and a physical game. This game includes, ping pong, cups, water, and two groups of three or two facing each other. You have to play this game on a long table so there’s enough space for the pingpong to bounce or just basically, making it a bit harder for players to shoot a ping pong. Both ends of the table needs to their cups with water in a pyramid or triangle. Once done, both groups will have a throw alternatively. Whoever ran out cups first wins.

How was your hauora was impacted by participating in today’s activity? 

My Hauora (Taha Tinana) was impacted by participating in the activity because I get to kind of stretch out some of my muscles during the game and I think that it impacted my Physical area in my Hauora. It also impacted my Taha Hinengaro (Mental) because it also made me think of a method to use for my pingpong balls to land inside the cup accurately.

What is important to know or understand when participating in a game with others?

It is important to know that communicating with your teammates is important when participating in games with them so it makes it easier for your team to win the game. It is also important to have teamwork and let others play when working in groups because it is also a way to succeed and win the game.

Social Studies – Greensboro 1960 Sit-in

The Greensboro 1960 Sit-In all started on February 1, 1960 at the F.W. Woolworth’s department store lunch counter in Greensboro, North Carolina when four Black North Carolina A&T State University students sat at the “Whites-Only” lunch counter at a F.W. Woolworth’s store in Greensboro, North Carolina, and politely requested service. But unfortunately they were denied service but remained seated until the store closed. It happened because four boys were inspired, in that matter they were furious against the discrimination received from the ruling of the local F.W. Woolworth store. 

By February 4, 1960 from being four students to having hundreds of participants and eventually involved thousands, sparking a nationwide movement against segregation. The protests continued for months until the F.W.Woolworth lunch counter was desegregated on July 25, 1960.

Here is a picture of the Greensboro Sit-In to help you picture more of what the protest looks like:

The result of Greensboro Sit-In was the desegregation of the lunch counters at Woolworth’s and other stores in Greensboro within six months. It also resulted in disrupted business that led to a significant boycott of the stores, further pressuring management to change politics.

And lastly, the Greenboro Sit-In protests matter today as a historical turning point that generated the national Civil Rights Movement by demonstrating the power of nonviolent direct action, leading to the desegregation of lunch counter and contributing to the formation of the Students Nonviolent Coordination Committee.

That’s all for my blog post today, Paalam!

Music – Group Performance

Kamusta bloggers, today my blog post will be all about sharing with you all what our progress in music for our group performance/band.

Our band consists of four members; those four members are: Kate, Kirsten, Samantha, and me (Xyryll). The instruments that were used are Electric Guitar, Piano, Drums, and Vocals. Our roles are Kate is doing the electric guitar, Sam is doing the piano, Kirsten is doing the singing and I’m doing the drums. Our progress is basically just the intro of our instruments and trying to be in sync–especially the drums, electric guitar, and piano. What we are currently trying to aim for is being able to be in sync at least 10 seconds into the song.

That’s all, thank you for reading my blog post, Ka kite!

Dance

Everyone can Dance

Kamusta bloggers! Today for Dance I will be sharing with you all some things you need to know about our subject Dance.

This term, we are learning how to work together and create a dance. Making/Creating a dance includes manaakitanga. (Here are some synonyms of manaakitanga to help you: hospitality, kindness, and generosity)

For our warm up this lesson, we did a Haka dance with the whole class.

If you don’t know, Kapa Haka is an avenue for Maori people to express their language, culture and heritage through song and dance. It occurs in both informal and formal settings — on marae and sports fields, at iwi, Maori, hapu and whanau events.

Kapa Haka can be competitive or non-competitive. It can be performed by any number of people, men and women, young and old. Music for Kapa Haka is primarily vocal and sung in Te Reo Maori (Maori Language.) And lastly, if you don’t know yet, Kapa means to stand in a row and Haka means to dance.

Here is some more information!

who? = Maori people

what? = Kapa = to stand in a row Haka = to dance.

where? = on marae and sports fields, at iwi, Māori, hapū and whānau events, in schools and education organisations, in community and business settings, and at Kapa Haka shows, events and competitions.

when? = the 1860’s

why? (why is it performed) = to provide a cultural connection for those separated from their culture by urbanisation.

how? = it involves choral singing, dance and movement connected with the hand-to-hand combat practiced by Maori in mainly precolonial times, presented in a synchronisation of action, timing, posture, footwork and sound.

Some other cultural other than Kapa Haka is the Filipino folk dance Tinikling.

Tinikling is usually performed using two bamboo sticks, two people who’s dance and another two people who will be having control of the bamboo sticks

Tinikling is performed by the bamboo stick being tapped twice on the ground on the first two beats, then brought together on the third beat. Two or more dancers then weave through the rapidly moving bamboo poles with bare feet and ankles.

Talking about cultural dances, where being inclusive is important, why is including everyone in Dance important? Some of examples of including everyone in Dance are letting them share their ideas, making sure that everyone is catching up and helping those who need more extra time with some skills, and lastly showing manaakitanga.

Why is showing manaakitanga important in Dance?

I think that manaakitanga is important in Dance because showing manaakitanga is being inclusive, kind to others who are struggling with some individuals skills and helping them, making sure that everyone is getting the chance to share what they have in mind, and showing manaakitanga in Dance doesn’t only mean having a good result but also getting to have fun not only with whom you’re familiar with but also with new people.

Dance in Musical 

What is musical?

Musical is a play or film in which singing and dancing play an essential part. Musicals developed from light opera in the early 20th century.

Here are different types of musical:

  • Book Musicals are the most traditional form of musical theatre, featuring a clear narrative structure with the songs and dances advancing the plot and character development. Examples of book musicals include classics such as “West Side Story” and “The Sound of Music,” as well as more recent hits like “Hamilton”.
  • Operettas are lighter, more comedic musicals with a focus on music and dancing. The best example of this type of musical is “The Pirates of Penzance”, which tells the story of a young pirate apprentice and features catchy tunes and witty lyrics.
  • Revue Musicals feature a rock music score, often with edgier themes and subject matter. Examples of rock musicals include ” Rent,” which explores the lives of struggling artists in New York City, and “Spring Awakening”, which deals with adolescent sexuality rebellion. The best of this type of musical is “Jesus Christ Superstar,” which tells the story of the last week of Jesus’ life and features a classic rock score by Andrew Lloyd Webber and Tim Rice.

Why is there dance in musicals?

There’s dance in musicals because through dance, it expresses the characters feelings and thoughts. It also helps tell the story and expresses the unspoken mood of a song, and makes a good transition in time or places.

Final Blog; What we learned 

What did we learn this term for Dance?

What we did for the first two weeks in our dance lesson is learning how is Manaakitanga connects to dance. Which we wrote our thoughts/answers to a blog post. The second topic that we did was why is there dance in Musical. Before we wrote our answer what we did was watch some musicals which have some movements in them, and there, we write our answers which can also be found in our blog posts. There are also lessons where we learned some cat movements and also performed them in groups in front of our classmates. We also watched some cultural dances, learned a thing or two about them and also performed them.

We also watched some bands perform some music for us, which I really enjoyed. We were also given the chance to watch some of the performances that were included in the Show Quest.

Overall, we had a pretty short lesson since this term only lasts for 9 weeks. But in that 9 weeks, I really enjoyed this subject and it really helped me build more confidence with nonperforming dances.

Social Studies – FACKTS

Kamusta bloggers! Today for Social Studies, my task is to share with you all what our topic/what we were learning about in Social Studies! Our topics for Social Studies these past few weeks are learning more about maps a.k.a, FACKTS: Frame, Arrow, Colour, Keys, Title, and Scale.

Frame means the wavy line around the actual map. Arrow is the North, East, South, and Wets (Never Eat Soggy Weetbix).  Colour is the colour of the map you drew. Keys is giving the symbols on the map that drew a name (e.g mountains, trees, river). Title is the name of the Island/the Map that you drew. And lastly, Scale is like saying how long the distance is between places to places.

Here is my D.L.O about FACKTS to help you understand more about Mapping/FACKTS!

I hope that my brief explanation about FACKTS and my D.L.O helped you understand/answered all your concerns about Mapping or FACKTS.

That’s all for my blog post, thank you for reading! Ka kite!
