FEATURING - WORLD'S OCEAN DAY
World's Ocean Day is on the 8th of June so we asked our students to write us about any topic that is related to the Ocean. Let it be saving the Oceans, pollution or the animal world. It is vital that the young generation understands the importance of keeping our oceans healthy and that they feel this is something they can contribute to. We are very proud of our students to write such seriously thoughtful essays on this topic. Well done!
World’s Ocean Day
Our Oceans and the climate change
Oceans are the foundation of our planet, therefore they are the foundation of our lives too. They cover 71% of our planet’s surface.
Oceans control the global climate they are also the world’s largest store of carbon. An estimated 83% of the global carbon cycle is circulated through oceanic waters.
However this relationship between the two natural forces is changing, and the exchange is intensifying. We’re seeing the results of this worldwide. The oceans have absorbed 1/3 of the CO2 produced by human actions, and there is a big amount of heat trapped by the increasing concentration of greenhouse gases too.
As the climate reacts to the increasing carbon emissions, the store of energy and heat from the atmosphere builds up in the oceans. That is how the climate change affects our waters. If we reach a turning point, we will see extreme weather events, changing ocean currents, rising sea levels, and melting of ice sheets.
But the perhaps greater concern is that the basic chemistry of oceans is changing faster than it ever has because of the constant absorption of CO2 there is an increase in acidity levels. When it is combined with the warming of our oceans, more coral reefs are dying off and can no longer provide a healthy habitat for the species that rely on them. Scientists estimate that by 2050 if the current rates of temperature increase continue, the oceans will become too warm for coral reefs.
Luckily, a lot of people started to raise awareness of the current problems, and they are all trying to secure a living ocean for a healthy global climate.

Special gift to Marine and the Ocean
I read a short story on the internet about a 12-year-old child prodigy, Haaziq Kazi from India who is building a ship to clean the Oceans. I was so fascinated about the story that I had to watch his TED-Ed talk.
I admired his story and his TED-Ed talk, because of the fact that a boy younger than me is capable of accomplishing such a project and also because I, personally, was thinking a lot about water problems on the Earth. I was thinking a lot about controversial facts like the warning that we will face huge water problems in the next 50 years, while 70,8 % of the whole planet is water. Only 1 % is fresh water of this 70,8 % but there already are a few methods of desalting the salt water and making fresh water of it.
And then, here he comes. A boy reminded all of us how we could have done more for our world. Kazi wants to clean up all of the Oceans on our planet and help the marine to survive.
He first built a prototype ship for the cleaning of the Ocean. Everything started when Kazi saw a photo of a dead whale that was washed to the shore in the Northern Netherlands. He was shocked by the bloated stomach of the animal. People found 2 hose pipes, a 9-metre rope and 37 pounds of plastic inside the whale. The official reason for its death was “intestinal blockage” which is a very serious illness I know well, since my doggy had the same diagnosis after swallowing a sock.
After this shock, Kazi started watching Nat Geo, Discovery videos and documentaries of different marine experts. Kazi spent not less, then the next few years reading and researching about the different causes of death of marine animals. And then, suddenly, he got a school project to talk about the things he cared about.
The starting point, the origo was when he saw water flowing into the sinkhole. He came up with this idea when he was washing his hands. The way water swirled and was sucked into the pipe influenced Kazi. He asked for support from his teachers at his International school and a 3D designer. Kazi’s ship looks like a huge vacuum cleaner. It is called ERVIS. The ship is powered by hydrogen and renewable natural gas. The waste hits the oil filter first, then goes to different chambers. After the oil filter, the other waste samples are also segregated into four chambers, that are for large, medium, small and micro waste. The ship also contains a segregator to separate plastic from non-plastic items. The plastic items are compacted and stored in cubes. The other wasted items are degraded with bacteria or stored away for separate disposal. Since the ship is powered by hydrogen, it combusts with oxygen, giving water and injecting back the clean water into the Oceans. Kazi is actually not just a very good thinker and a high IQ kid, but also an amazing presenter, believe me. You can judge it yourself, by watching his TED-Ed CLUBS talk.

Tectonic plates and Plate Boundaries
The Earth’s outer shell, called the lithosphere, which consists of crust and uppermost mantle, is divided into a patchwork of large tectonic plates that move slowly to each other. There are 7-8 major plates and many minor plates. Varying between 0 to 100mm per year, the movement of a plate is driven by convection in the underlying hot and viscous mantle.
Natural disasters and formations, such as earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along plate boundaries in zones that may be anything from a few kilometres to a few hundred kilometres wide.
There are some occasions where two plates are colliding under the ocean, forming plate boundaries. Such boundaries can happen either when oceanic crust meets oceanic crust or when oceanic crust meets continental crust. As soon as this occurs, the energy is released and causes earthquakes, enormous sea storms and tsunamis.
As seen in the image above, the majority of the tectonic plates are found under the oceans. 8 days ago the world was notified about the following event: a giant tectonic plate under the Indian Ocean is breaking in two. The plate, known as the India-Australia-Capricorn tectonic plate, is splitting about 1.7 millimeters a year and it's so far underwater. Therefore, researchers started to investigate more about this unexpected phenomena. Two enormous clues — that is, two strong earthquakes originating in a strange spot in the Indian Ocean — suggested that Earth-changing forces were already predicted.
On April 11, 2012, a magnitude 8.6 and magnitude 8.2 earthquake hit beneath the Indian Ocean, near Indonesia. These quakes originated in a weird place for earthquakes to happen — in the middle of the plate. These earthquakes also indicated that some kind of deformation was taking place far underground, in a place, called the Wharton Basin. Scientists found evidence for strike-slip faults. These types of faults cause earthquakes when two blocks of Earth slide past each other horizontally.
As a conclusion based on the datasets, it can be said that due to the fact that different parts of the India-Australia-Capricorn are moving at different speeds, this fracture zone is becoming the new boundary for the plate's split into two pieces.
Life most probably originates from the sea (primordial soup theory, Fig. 1.) [1]. Although we colonized the lands quite deep we still depend on food sources of the ocean as evolution needs lot more time to adapt changes. Unfortunately people of modern civilization tend to forget and ignore how we can live in balance with nature and this behavior results in many health issues. Figure 1. Primordial soup or prebiotic soup is the hypothetical set of conditions present on the Earth around 4.0 billions years ago. It is a fundamental aspect to the heterotrophic theory of the origin of life, first proposed by Alexander Oparin in 1924, and John Burdon Sanderson Haldane in 1929 [1].
Our oceans are the main source of an essential element, called iodine (Fig. 2.). Iodine is mostly known as the element that is required for thyroid hormone production; however, iodine is found in each cell of our body. Without adequate iodine levels, life itself is not possible [2]. Iodine is not only necessary for the production of the thyroid hormone, it is also responsible for the production of every other hormone in the body. Adequate iodine levels are necessary for proper immune system function and are essential for normal growth and development of children. Iodine contains potent antibacterial, antiparasitic, antiviral, and anticancer properties [2]. Approximately 1.5 billion people, about one-third of the Earth's population, live in an area of iodine deficiency as defined by the World Health Organization. Iodine deficiency disorder can result in mental retardation, goiter, increased child and infant mortality, infertility, socioeconomic decline, spontaneous abortion, delayed physical and intellectual development and attention deficit/hyperactivity disorder (ADHD) [2]. In addition, breast cancer is also associated with iodine deficiency [2, 3, 4].
Figure 2. Iodine: sources and importance. A: Evaporating violet iodine crystals. B.: Lugol solution which is a way to supplement iodine C: results of iodine deficiency D: the natural source of idoine: Gigartina sp. seaweed
Iodine is not very abundant in the Earth's crust, it is a relatively rare element. It mostly can be found in sea organisms, such as Gigartina sp. seaweed [2]. In fact, seaweed is one of the richest sources of iodine because seaweed has the ability to concentrate a large amount of iodine from the ocean water [2]. Archaeological finds in Chile show that it was already known 15.000 years ago. In a medicine men’s hut 9 different species of algae were found far from seashore [3]. If we are not able to consume iodine in the required amounts from natural sources we have few possibilities to supplement it (Fig. 2.)
The other ocean-related nutrients are the omega-3 fatty acids. The ratio of omega-3 and omega-6 fatty acids is essential for the appropriate functioning of our body, as each cell in the body produces anti-inflammatory hormone-like substances from the omega-3 fatty acids, while the excess consumption of a certain omega-6 fatty acid results in the production of pro-inflammatory substances [6]. The majority of the most common diseases (lifestyle diseases) develop due to high levels of overall inflammation, just as aging is accelerated by the elevated levels of inflammation. The human body is genetically “designed” for a ratio around 1:1 of omega-3/6 fatty acids. The fatty acid ratio in the bodies of our ancestors were close to 1:1, as it is still in some very healthy ethnical groups. Unfortunately, the current low consumption of salt water fishes and other seafood, in addition to the excess consumption of vegetable oils and fats of fed animals, both with high omega-6 fatty acid levels, this ratio has shifted significantly towards omega-6 (1:8 - 1:32). This shift is the cause for many diseases [5, 6]. In order to restore this ratio, the best is to decrease the consumption of food rich in omega-6 considerably and to eat salt water fished and other seafood multiple times a week (Fig. 3.). Beneficial effects of appropriate levels of omega-3:omega-6 decreases depression, aggression, irritability and bad mood; promotes learning processes and improves intelligence, increases brain weight, helps brain development, especially in case of appropriate intake during pregnancy and childhood; helps maintain the elasticity of blood vessels, regulates cardiac rhythm and the level of cholesterol; decreases the risk of thrombosis, stroke and infarction, just as triglyceride and blood pressure levels; helps prevent the developing macular degeneration (AMD) and dry eye syndrome, beneficial for the capillary vessels of the eye; due to its strong anti-inflammatory effect, it was found to be effective against rheumatic arthritis; helps maintain the health and shine of hair and skin; the telomere that protects the ends of the DNA-strand is shortening more slowly in people with high blood levels of EPA and DHA, which is currently the most accurate marker of life expectancy [6].
Figure 3. Omega-3 sources
In conclusion, we have to be aware of our evolution and cannot ignore the fact that we still depend on our oceans. We have to respect and protect our oceans, keeping our planet and body healthy.
The deep sea holds many mysteries that people have been slowly uncovering throughout the years. Yet there is still a vast majority of the deep sea to explore. Multiple myths have surfaced throughout the years claiming things such as, sea monsters existing or even an underwater civilization. Although we know that these things are most likely not true, we don’t have a definite answer to what is happening in the deep sea. Only a few had got to experience the world below 4,000 meters. The deepest that man has ever gone was 10,927 meters. A record set by explorer Victor Vescovo on April 28, 2019. This depth is quite close to the bottom of the Marina trench which rests at an indefinite depth of 11,000 meters. It's considered to be the deepest part of earth. Not only is the pressure immensely high but it is also pitch black. So naturally, only species that are adapted to that kind of environment can survive in the abyssal and hadal zone (Fig 1.). Whilst Vescovo was exploring the unknown, he had discovered four new species of amphipods. Although, the creatures that Vescovo saw, weren’t the first ones to be found in the abyssal zone. There are several interesting and unusual amphipods that defy odds. But how do these miraculous creatures survive the remote abyssal and hadal zone?
There are many animals in the abyssal zone that possess many special traits. One of them being bioluminescence. The definition of bioluminescence is the production of light by a living organism. A good example of this is the anglerfish (Fig. 2.). Most people have seen images of this creature because of its unique jaw, set of teeth and bioluminescent abilities. There are over 200 species of anglerfish that live in the Atlantic and Antarctic oceans. These fish are known for their appearance. Most notably for their fishing rod-like thing which is called a lure. This lure is only worn by females. The use of the lure is to trick the prey into thinking that it is a worm. As soon as the prey approaches the lure, the anglerfish opens its mouth and uses its sharp razor like teeth to devour the prey. The most interesting part about the anglerfish is that when a female and a male mate, the male will latch onto the female by his teeth, which releases an enzyme that attaches the skin of his mouth to her body(Fig. 8.).During this time, the male fish will live off of the female anglerfish, meaning that he gets all his nutrients from the female, in exchange for his sperm. The male will lose his sight and almost all his organs starting with his digestive organs. The only thing that will be left of the male is a pair of gonads. These are used for releasing sperm in response to hormones in the female’s bloodstream indicating egg release. At once, a female fish can mate with up to six male anglerfish. Although the abyssal zone isn’t actually the deepest part of the ocean.
The deepest part is called the hadal zone, named after the Greek death god Hades. Here, many translucent sea creatures can be found. An interesting case is the Abyssal Cusk-Eel (don’t let the name fool you, it is a fish). Even though it has abyssal in the name, these fish tend to swim down further into the hadal zone. The abyssal Cusk-Eel and the snailfish are the only fish that are known to survive in the hadal zone (Fig. 3&4.). But what makes them so special, that no other fish can survive down there? The answer is that the deeper you go in the ocean, the higher the pressure is. At one point the pressure gets so high, that even protein will destabilize. Which means that the molecular machinery inside the fish’s cells will break down. Although, the Abyssal Cusk-Eel and the snailfish both contain a special compound called trimethylamine oxide (TMAO) which stabilizes their proteins under extreme hydrostatic pressure. Although these fish can only withhold a certain amount of TMAO because if the concentration gets too high, the fish’s cells won’t be able to handle it. Another strange animal is the Hirondellea gigas (deep-sea shrimp, Fig. 5.). These shrimp live at the very bottom of the challenger deep. But how does it survive down there? Well, the H. giga can actually make its own suit of aluminum armor. It releases a layer of aluminum hydroxide gel over its exoskeleton. From all the mineral rich sediments that the H. giga consumes, it can chemically transform the aluminum ions into a gel.
As I have said before, many fishes were discovered in the deep ocean. But what people don’t usually talk about, is the other things that were discovered. In 1977 Hydrothermal vents were discovered along the mid-ocean ridge in the eastern Pacific Ocean, when scientists discovered a series of spikes in the temperature (Fig 6.). Along with those vents, over 590 new species of animals have been discovered living on the vents. Although, what's even more interesting is the wide range of bacteria that live on the vents. The bacteria on these vents meditate the transformation of energy and minerals produced into organic material. The organic material that is produced, is used to maintain the upper trophic levels. One species of bacteria is called hyperthermophile which is a type of thermophile.This bacteria is known to be one of the toughest because they grow in temperatures above 80 ℃. Thermophiles have simple diets which consist of metals, gases and minerals. They produce enzymes which are useful for high temperature situations.
In conclusion, I feel as if most parts of the ocean are yet to be discovered. As technology evolves, so will our understanding of the ocean because we will be able to reach new depths and explore much more difficult areas. Although I’m concerned because pollution is affecting the animals in the lowest parts too. Whilst Vescovo was in the hadal zone, he had collected samples of the Hirondellea gigas and had found micro plastics in their guts. Not only that but Vescovo had also found a plastic bag and candy wrappers. It is truly concerning because if we don’t start saving our oceans, we might lose something that is yet to be discovered.
Aquatic Environment Impacts of the Microplastic Beads Used in Cosmetics
Microplastic beads usage in personal care and cosmetic products has been established as one of the prime sources and routes through which persistent, potentially harmful plastic materials can be emitted to the marine environment [1]. Everyday use of personal care and cosmetic products releases these plastic particles directly into wastewater as, for the most part, the products are washed off or rinsed down the drain during or after use. A typical facial scrub contains approximately 350,000 microbeads [2]. Over half of women use four or more beauty products a day (estimated global spending by women: $426 billion a year), and a large portion of those cosmetics consists of products containing microplastic beads. Alternatives of Microplastic Beads
Usage of microplastics in cosmetics have emerged as a major environmental concern. At the same time, the popularity and worldwide prominent sale of these cosmetic products containing microplastics make it difficult to eliminate those products from use. Hence, a safer substitute is required to replace these environmentally hazardous constituents. World plastics production has experienced almost constant growth for more than half a century, rising from approximately 1.9 tons in 1950 to approximately 330 million tons in 2013 [3]. A recent study had revealed that 5.25 trillion plastic particles weighing some 269,000 tons are floating on the surface of the sea. The option to remove the accumulated plastic load from the ocean is time consuming, costly as well as non-viable on some aspects. Moreover, this operation will simultaneously remove the normally abundant microscopic yet significant planktons and other flora and fauna from the food chain, which may disrupt the entire marine ecosystem. Thus, the only option is to minimize and, if possible, cease the entrance of more plastic in the lakes, rivers, seas and ocean. Organizations (Ocean Conservancy, Plastic Pollution Coalition, 5 Gyres, etc.) are working with scientists, politicians and industries to aware the public about the problems related with the use and discharge of microplastic beads [2]. Different multinational companies like Avon, Beiersdorf, Colgate-Palmolive, Henkel, L' Oréal, Oral B, Procter and Gamble, Unilever etc had announced that they would phase out the use of microplastics in their cosmetics products. Many other personal care product companies are voluntarily phasing out the use of microplastics in their products.
Biodegradable polyhydroxyalkanoate (PHA) was suggested as a possible alternative to traditional microbeads for cosmetics and personal health care products [4]. Being soluble, PHAs minimize the potential threats of microplastic beads in the environment. PHAs can biodegrade in either aerobic or anaerobic environments. The scientists have also demonstrated the faster biodegradation rate of PHAs in comparison with other traditional synthetic polymers. Application of the PHA microbeads into personal care formulations such as exfoliants, cosmetics and toothpaste would significantly reduce aquatic pollution.
The permanent solution of this new-age pollution will necessarily require a combination of more scientific research to determine where to best put effort and resources, technological innovations and public/policy initiatives to refuse, reduce, reuse, recycle and rethink so that the flow of plastic to the environment is deprived.

World ocean day
Planet earth is mostly covered by water, more than 70% of it. Water is our most valuable resources, as it cleans air, provides the basic component of food and other everyday activities. Oceans are also home to most organisms, for microscopic algae all the way to the blue whale, the largest animal on the planet. Still we are bombarding them with pollution every day. The majority of ocean pollution is plastic. The biggest problem with it is that it is not biodegradable. Just imagine all the single use grocery bags, water bottles, straws and food packaging that we toss into the ocean instead recycling it. On average 8 million tons of plastic are getting into the water yearly, which will not degrade for hundreds of years. Then the animals in the water get diseases, because of us, also it affects us as it can be found in our food as microplastics, which is a serious concern for our health. Humans also affect marine sea life by creating ocean noises. The issue with is that animals living in the ocean rely on communication by sound to find food, mate, and navigate. The artificial noises by humans harm their lives, even destroying some ecosystems. We only have 1 planet Earth, and water is the main component of it, so we must take care of our oceans.

Ocean Physics
All natural phenomena can be explained by the law of physics. This is true of the behaviour of oceans even if it is quite complex. Let’s consider the ocean currents for example:
An ocean current is a permanent or continuous, directed movement of ocean water. In 1992 an accidental event made the currents visible. 28,000 rubber ducks were plunged into the ocean after a shipping crate was lost at sea. The ducks made it halfway around the world, washing up on the shores of Hawaii, Alaska, South America, Australia as well as the Pacific Northwest.
What are the generating the ocean currents?
During the lessons I usually ask to find the reason of the phenomena at the level of particles, but in this case the explanation is planetary. The sun and the moon are responsible for everything. Wind, water density, and tides all drive ocean currents.
The sun heats up the different material of the earth in different ways. The sand, the ground can be heated easily but the water (due to its high specific heat) hardly. The temperature-difference results different level of density and pressure, therefore the air moves from high-pressure areas to low-pressure areas. Like air convection there is convection in the oceans as well due to temperature, density and pressure difference.
The gravitational pull of the Moon generates the so-called tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon.
What is the reason for the direction of ocean currents being opposite on the Northern and Southern Hemisphere?
Earth’s rotation results the Coriolis effect. Similar to a person trying to walk in a straight line across a spinning merry-go-round, winds and ocean waters get deflected from path as they travel a straight line across the rotating Earth.
The effect of human activity:
The North Atlantic Current transports warm water from the Gulf of Mexico towards Europe, providing a relatively mild climate for North-western Europe. However, scientists suspect that meltwater from Greenland and excessive rainfall could interfere with this ocean current. Simulations showed that there is a 15 percent likelihood that there will be a temporary change in the current in the next 100 years.

LITERATURE CORNER
Kedves Olvasók!
Elérkeztünk a "sorozatunk" utolsó, 5., befejező részéhez. Most a 11.N osztály három tanulójának versét olvashatják, mit gondolnak ők az élet értelméről, arról, miért érdemes ezt csinálni percről percre, napról napra, hétről hétre...
Nagyon örülök, hogy ez a sorozat megszületett, hogy ennyi szép, mély, érzékeny, kreatív, különleges alkotást kaptam. azt hiszem, hogy ezek után én már biztosan nem mondhatom, hogy igazán éltem... :)
Végül, de nem utolsósorban köszönöm Szilágyi Gerdának, Gottwald Leventének és Nyalka Juditnak, hogy megírták és megosztották a saját verziójukat, igazán értékes alkotások születtek. Szilágyi Gerda verse nagyon személyes, sok-sok érzékeny apróságot felvillantva, nagyon közeláll hozzám, Levi verséről szintén elmondható ugyanez, érzésekben, érzelmekben nagyon gazdak, sok-sok finom kis rezdülést mutat meg a nagyszájú kamasz amúgy érzékeny lelkéből, s nem is ő írta volna a verset, ha nem az az utolsó sora, ami :), Nyalka Judit verséből pedig kiderül, hogy járt a világ leghosszabb katakombájában, látta élőben a CMS detektort, volt jávorszarvas teszten és hogy tud töltött paprikát készíteni. Ki gondolta volna? Csupa meglepetés - köszönöm judit!
Kedves szülők, s nemcsak szülők, hanem mindenki, aki követte ezt az öt részből álló sorozatot és olvasta a sok-sok (már magam sem tudom, pontosan hány) verset, most már talán megértik, miért szeretek annyira kamaszokkal dolgozni. Látják, hogy a sokszor nagyszájú hőzöngők mögött milyen érzékeny, bölcs, friss, élettel teli kis emberkék rejlenek, akik ha megmutatják magukat, az ember hálás a sorsnak, hogy ebben részese lehet, s nekem részem lehet majd minden nap. Köszönöm nekik, köszönöm, mindenkinek aki írt - azoknak is, akik most esetleg nem kerültek be az újságba, boldog vagyok, hogy ez a sorozat megszületett. S igen, reményeim szerint jövőre is lesz valami hasonló, hogy ne maradjunk irodalom nélkül.
(Vereckei Réka - magyartanár)
Szilágyi Gerda
Nem éltél igazán, amíg...
Nem örültél teljes szívedből,
Nem nevettél annyira, hogy már hullottak a könnyeid,
Nem szundítottál el nap közben, egy átalvatlan éjszaka után,
Nem láttál egy erős férfit könnyezni,
Nem vallottak neked szerelmet,
Nem vallottál te magad szerelmet és
Nem utasították vissza azt,
Nem úsztál delfinnel,
Nem láttad a napot lemenni Párizsban,
Nem ettél egy igazán finom nutellás palacsintát,
Nem csináltál butaságot, de végül nem bántad meg,
Nem ölelkeztél hosszabban a kelleténél, csak mert szükséged volt rá,
Nem hallgattad meg századszorra is azt a bizonyos dalt,
Nem kaptál egy őszinte levelet, arról, hogy milyennek is lát az általános iskolai legjobb barátnőd,
Nem ettél fagylaltot a Duna partján ülve,
Nem próbáltad ki a víziejtőernyőt,
Nem estél el görkorizás közben,
Nem fagytak meg az ujjaid a barátaiddal való korcsolyázás közben, hogy aztán átmelegedjenek mikor
forró csokit isztok,
Nem aludtál együtt a macskáddal,
Nem gitároztál,
Nem törtél össze valamit, aztán nem titkoltad el azt,
vagy nem fogtad a nővéredre,
És végül: nem éltél igazán, amíg nem érzed úgy, hogy igazán éltél, mert a kor csak egy szám és sosem késő.
Gottwald Levente
Nem éltél igazán, amíg...
nem esett jól a fájdalom
nem érdekelt semmi csak a pillanat
nem vezetett a csapatod 1 góllal és az ellenfél támadott a végső percekben
nem sírtál örömből
nem csináltál egy akkor jó ötletnek tűnt dolgot, ami mégsem volt az
nem törtél össze mindent vereség után
nem fogadtál a teljes esélytelenre és bejött
nem sírtál annyira egy sorozaton, hogy nem is értetted, mi van veled
nem aludtál szinte egész nap
nem utaztál barátokkal sok-sok órát
azt hitted valakinek fontos, vagy de nem
nem helyzeted saját érdekeid előre
nem mentél ki hajnalban mezítláb a kertbe
nem esett jól a jéghideg és tűzforró
nem vitted végbe a terved
nem cáfoltad meg azt, aki kételkedett benned
nincs új vágyad minden nap
nem ettél annyit, hogy igazán tele légy
nem húztál jó tételt
nem csalódtál
nem aludtál el olvasás közben
nem kellett magyarórára verset írni.
Nyalka Judit
Nem éltél igazán, amig…
Nem ettél egy jó saslikot
nem szabadultál ki a világ leghosszabb katakombájából
nem éltél meg igazi vihart a tengeren
nem próbáltad ki élesben a jávorszarvas tesztet
nem láttad élőben a CMS detektort
nem jártál a világ legnagyobb sátrában
nem öntött el a boldogság, amikor elkészítetted életed első töltött káposztáját
nem lepted meg saját magadat azzal, hogy van egy addig nem ismert képességed
nem találkoztál valódi hősökkel
nem éltél meg igazán nehéz időket és így bölcsebben mentél tovább
nem mentettél meg valakit, akinek csak te segíthettél.

Return to Preschool
It was a welcome return to the preschool after months away at home doing OTL lessons. The children were excited to have the chance to see each other in person once again and straight away got back into normal school life although school life is not exactly back to normal yet. Our Spanish classes are still continuing OTL format with Alvaro being isolated in Spain but at least we can all follow his lessons together in the classroom.
The children were quick to learn our new routines with drop-off and pick-up being one of the bigger changes to our daily routine. This week the children have been learning about summer with many of our lessons being performed outside the classroom with a lot of active activities.

My Own Filter
To end off our science chapter, ‘Material Changes”, for the term the Year 6 students explored how to make their own filtration system. Their goal for this activity was to discover that ground materials can clean and purify water before it is returned to the surface.
The criteria for the investigation was that their filter system needed to be durable and easy to use, have three layers and the layers needed to be made of ‘natural’ materials that they could find in their yards or nearby park. They could also make use of recyclable materials.

Farewell Sirius’2020
Every year SEK Las Américas prepares a farewell lunch for our 12th-grade students, sadly this year we haven´t got the chance to get together physically to spend a moment with them, but the Pandemic didn’t stop us from preparing them a special surprise. Last Monday our Staff prepared a unique lunch for our graduate students through the Zoom platform, we sent each one of them a surprise cupcake, we talked about our memories and best wishes for all. The most nostalgic moment was when Ms. Vicky surprised them with the song “The Climb” and every teacher showed a handwritten message.
