Endo vs Exo Which side will you take?







Introduction   
  
     In chemistry class you might of heard of the words "Endothermic" and "Exothermic". If you are like me you would of wondered what exactly did those words mean. I mean they sound similar, how much of a difference could there be? The answer Endothermic reactions and Exothermic reactions are night and day. The following will showcase the differences between the two words.

                                                   Endothermic                                       Exothermic 




     There are so many different types of learners in the world today. I for one learn best when I am able to experience or physically do something. So in this light the STEM academic strand students at SSIS Malarayat did an experiment focusing on the Endothermic and Exothermic reactions of Acids and Bases.


Procedures


Perform the following procedure, and identify each as either endothermic or exothermic, through temperature reading. For all procedures, take not of the initial temp. reading of the first solution/water, and then, the final temp. Draw a complete energy level diagram for each.

  1. Mix 10 mL of dilute hydrochloric acid and 10 mL sodium hydroxide. Perform this cautiously by adding the acid TO the base in incremental amounts
  2. Prepare 1 g of zinc dust in a test tube. Add 10 mL dilutated hydrochloric acid.
  3. Dissolve 1 g of barium chloride in 150 mL water.
  4. Dissolve 1 g of ammonium chloride in 150 mL water.
  5. Dissolve 1 g of sodium hydroxide flakes in 150 mL water.
  6. Dissolve 1 g of magnesium nitrate in 150 mL water.
  7. Add 5 mL of potassium dichromate to 15 mL ethanol.
  8. Add 1 g of anhydrous copper sulfate in 25 mL water

Never Trust an ATOM


Never Trust an Atom (They make everything up)






       Counter clockwise from the bottom right you will see "Early Earth, The First Cells, a Volvox, Everything is made up of atoms, and an organic molecule". In the Mind Museum I entered an division called Atom Gallery : The Strange World of the Very Small. When you first enter the exhibit you are treated to this cool compartment with black lights. Almost everything in that compartment glowed in the dark, even me since i was wearing a plain white tee. After exiting that compartment you are opened to a plethora of different exhibits. The one exhibit that drew my eye was this huge different colored dome that comprised of hexagons and pentagons. I inched closer and closer to that exhibit, when i got to just in front of it i stopped and saw that the name of the exhibit was "Organic Molecule". I entered the dome and was awe struck that each of the colors had a specific element associated with it. The associations are as follows :

0 C : Carbon
0 N : Nitrogen
0 O : Oxygen
0 H : Hydrogen
0 S : Sulfur

       I realized this dome relates to a concept we were learning in Chemistry at the time which was the Periodic Table. Each of the atoms present within the dome are Elemental atoms, which in this case can be found in the first three periods of the periodic table. This exhibit is an organic molecule as evident by the numerous carbon bonds. Now why is this an identifiable factor on organic molecules? The answer, carbon is important because it is literally the back bone of life. Without carbon there would be no life, and in turn no humans. Carbon is an essential part of every living being, beit plant or animal.

       I recommend coming to the Mind Museum in Taguig, Metro Manila, Philippines. With a multitude of interactive exhibits anyone can learn about science in a fun non-boring way. Not to mention all the Instagram opportunities in there. I really had so much fun here and will definitely return for more learning.

Aromas 101

      In this experiment I learned that you should have all your proper materials and manage your time wisely. Our group had no high temperature tolerant glass jars and both that we put up cracked and made a huge mess. Time pressure was a big factor here we did not manage our time wisely that why we weren’t able to complete the procedures. Our group repeated the experiment yet again to try to avoid the mistakes we made in the first place. We were more successful this round because instead of glass jars for boiling we used the boiler for heating the mixtures. We still didn’t manage our time wisely. We only managed to complete two esters and we didn’t even test the pH for those specific esters.

      My group panicked when the glass jars cracked I was just calm but they were shouting and pulling me back. This is what the group should’ve done. It’s a glass jar that cracked it won’t kill you and the liquid inside was just water. The group should’ve calmly moved back let the water flow out and then clean it up later.


      All in all our group made many mistakes and we learned from them. I enjoyed this activity very much because we created something from virtually nothing. It was really amazing that combining an organic acid with an alcohol would create a smells that I would usually associate with perfume.

Mikkel RUN! FRISBEE TIME

      Frisbee was one of the most rewarding experiences that i have ever done. I didn't expect it to be so much fun. Frisbee is like a combination of football and basketball but instead of a ball we use a disc. I was utterly shocked that Ultimate Frisbee had no referees. Frisbee is truth sport, you must trust that the other team will say the right call. A lot of trust is being placed into this sport.

      For me, my main sport being football i think that Frisbee is harder because i myself have no hand eye coordination i'm all about the feet. It was nice having a coach from our very own lodlod team try to teach us how to play Frisbee. At the start it was very hard going trying to get a hang of this sport but, coach Inan truly had so much patience with us and tried his very best to mold us into people who can play the sport. We spent weeks practicing, practicing, practicing without our coach though we wouldn't have the skills we have today.

      The news of a new sport spread like wildfire here in Stony everyday more and more people got interested in this amazing sport. It got so popular we actually got players from the Philippine team to come here talk about Frisbee and participate in a game with us.

      I for one am glad that Qiara Gutierrez a fellow grade 11 student recommended we do this at the beginning of the year. Without her recommendation Frisbee would've never made it into the halls of Stonyhurst.

   So the students of SSIS could learn more about frisbee we had a kind of clinic the day before the actual sports event. It was so hard to try to get them to cooperate since most of them are young they just wanted to go with their friends but we found ways and taught them the basics of back hand, fore hand, defense, and offence.

      The sport got so popular that we actually held a sports event right here in SSIS - Malarayat. We divided the grade school into their respective intramurals team. The eliminations were first it was Green Vs Yellow and Blue Vs Red. To be impartial i went to the blue team to proctor them. I was so happy in coaching them they listened very well and took direction. The winners of the eliminations were the Blue and the Green teams. They battled it out for the championship. It was so intense the score was 2-2 and then BOOM blue team scored i was so happy for them.

What is the World Made out of?



Since the beginning men have been asking the questions what is out there, how did we get here, and what is the world made of?

Out of all of the human endeavors Science has had the greatest impact on our lives, it’s our ideas, our achievements, and our results that surround us today. Moments we many call “Eureka” moments are the history of science these moments were not only made inside of a sterile laboratory but out in the world as well. The ideas that derived from these moments changed the world we live on today.

The history of us is a magnificent tale of power, proof, and passion.

Did you know that appearances are deceiving? You might look at our world today and think there is so much solid matter however this is not the case. Almost everything around us is empty space, if you took out all the empty space in the world the mass of the Earth would fit inside a single sugar cube.

As our thirst for knowledge continues to grow, people had tried to understand and alter the world in the middle ages; these people were called alchemists. These “alchemists” protected their secrets through codes and ciphers along with astonishing practical abilities.

Where did the middle ages scientists base their understanding of the matter? The answer is the Greeks, the Greeks that everything in the world was a combination of the four elements: Water, Fire, Earth, Air.


A brilliant alchemist brand thought that he was close to finishing the Philosophers stone, which was a mythical object that could turn any element into gold.

Alchemists thought everything on earth is living, even metals which can then be transformed, mutated, and purified.

Through many trials brand discovered something unexpected, which was phosphorus.

Brand, through a complex process, extracted a white stone from urea in human urine. This white stone is white phosphorus which is phosphorus in its most natural form. The name phosphorus means giver of light, which was an important for the later invention of the match stick. 



A scientist in Yorkshire, England going by the name of Joseph Priestley was looking for God not just in the Bible but also in the natural world he was one of the leading air experimenters in the world. He went to study air by heating substances including an alchemist favorite red calcx which is another name for mercury oxide. He found out that this red powder turned into liquid mercury when heated at high temperatures. The gases emanating from this included an element called oxygen. Priestly described this new air as “Good Air” which turned out to be the most important of the new airs discovered.

Priestly went to meet with a family called the Lavoisier's’ to tell them about the air he had discovered with fiery properties. The Lavoisier's for those who don’t know own the best equipped laboratory in Europe. Lavoisier called this “Good Air” Oxygen, the air off life. Lavoisier reversed the process and the gas and metals recombined to from red calx. An astonishing discovery was made the Lavoisier found out that this red calx weighed exactly the same as before. Antoine Lavoisier was considered the father of modern chemistry. 


The Lavoisiers' wanted to find out how to produce this flammable air in mass quantities . An apparatus was made to test of a water molecule can split two gases oxygen and the inflammable air which was later termed to be oxygen. This process of splitting molecules was called electrolysis. As a lighted splint was extinguished through hydrogen gas, a loud popping sound occurred. This inflammable gas actually inspired Napoleon to make a balloon military core.

One thing you might not have known about is that the Lavoisiers' was vulnerable because he collected taxes to make a living. Antoine Lavoisier however was not scared of this, and by doing this, he was put to death.

A scientist called Humphrey Davy heated potash ran electricity through it and found that by doing this the electricity broke apart the potash and a brand new element was discovered, Potassium.

One of the most famous authors in history, Mary Shelly was disturbed by Davy’s work, this influenced her to write her novel, Frankenstein.

Elsewhere up at the northern slits of the blue mountains stands a remarkable tree, this Cinchona tree was the best defense against malaria.

Cinchona  plantations were created all over the tropics. However, this could not satisfy the growing need for the bark. So Scientists turned to chemists for a synthetic version of the bark they succeeded by isolating quinine which was the active ingredient in the bark that combated malaria.



Electrons were first subatomic particles to be discovered.

A valve was used to amplify electrical signals or to switch binary signals.

The story of us what is the world made up was a comprehensive episode that showed the development of our understanding of science. I was actually amazed that they fit that much information in just under 2 hours. I never knew the alchemists played a pivotal role in science. I always thought they were the crazy people trying to turn lead into gold. It was amazing how many of the elements we have today were discovered by accident. Discovery is truly an astonishing thing.












TRUST THE PROCESS KINGS AT 10 ZUMBA EDITION


I woke up on the morning of February 7, 2016, it was an unusually cold this morning but nothing was going to stop me from getting to school and leading my group in the Zumba we had for SSIS Malarayat’s 10th foundation day celebration. I wasn’t nervous at first but when I got into the classroom my heart started to kept beating faster and faster because I didn’t want to mess up since I was the lead of my group. The time came and my group was first up our warm up song was club can’t handle me by Flo Rida and our 1st song was fire burning by Sean Kingston . So it was time I along with my amazing group mates went onto the stage and got into our positions.
My Group on stage ( Group 1 )
We started and it was going perfectly, none of us forgot a step and if we did we had MJ there to remind us the next step. I was truly amazed by the sight I saw on stage. The audience were actually participating, when I jumped right they jumped right when I jumped left they jumped left. It was so cool to see the bobbing heads of the entire SSIS Student Body.

WE DID IT, a weight has just been lifted off my shoulders. We are finally done, now it was Miss Rizchel's intermission number alongside grade 10 students Shane Mendoza and Chloe Perez. The dance moves were amazing as usual and it was really fun to do them. I looked to the audience and was surprised they still had the energy to push through with this intermission number. Everyone was so psyched to do this zumba though. I think it may have to do with missing part of their first period hahahahaha. The intermission was brief but tiring. I myself was very tired after that and we had two more dances to go with the other group. I can’t imagine the energy that the audience must’ve had to do all of these dances.
Miss Rizchel along with Shanes and Chloe
Ok Miss Rizchel’s intermission number was over and it was the other groups time to shine. They also had a total of two dances but this time instead of a warm up they had a cool down dance. Their first dance was Trumpets by Sak Noel & Salvi ft. Sean Paul then their cool down dance was All of me by John Legend. The other group’s dance was absouletly hilarious from body rolling to pumping. It was actually more fun than ours but C'est la vie. They then had a very nice cool down dance it really gave our bodies ample time to return back to normal after that somewhat intense physical workout. Can’t stop singing All of me, loves all of you….. hahahaha I’ll stop there your eardrums might burst.
Group 2

A few students wanted to their voices to be heard after the zumba activity. Let's see what they have to say shall we?

"It was fun.It made us happy. I like dancing,and since zumba is more of exercising,it's double the fun."- Hyun Ho Rho (Grade 6)

"The Zumba was a fun activity and not helped the students stay healthy, but also helped awareness for fitness levels. Children might've potentially realized how playing games will help them stay fit. So it helped a lot."
- Ben Ward (Grade 7)

"The Zumba was great! It was fun and I enjoyed doing it. It was nice to se everyone exercising and working hard but, having fun as well. It was very relaxing and calming and my body felt really refreshed after. I am looking forward to the next time we do Zumba."
- Victoria Vistan (Grade 8) 

"The Zumba activity released the school spirit by energizing the students with various moves. I enjoyed every moment. I wished the instructors prepared more for us. The activity helped in boosting the whole institution's physical and emotional mood and I hope to have more activities like it."
- Lila Hernandez (Grade 9)

"The activity is a success because the students were able to know the essence of exercising. Not only they enjoyed, they were also able to benefit from this activity by being energized for their upcoming classes. This activity can help make students realise that being physically fit is an important aspect of our lives."
- Eisen Villanueva (Grade 10)

"Honestly, I thought the whole event was successful. Everyone loved it, which satisfied me too." 
- Katya Mazloum (Grade 11)

Quantum Leap Reflection



In the documentary entitled “Quantum Leap” I learned many things. Such including that we as the human race created a set of laws that describes the clear and certain motion of galaxies, stars, and planets. However, we have discovered a brand new set of laws that completely change our view of the universe and redefining our understanding of reality these laws are known as the laws of quantum mechanics.

I never knew that quantum mechanics ruled over every atom and tiny particle in every piece of matter. In the quantum world, there’s a sense where things don’t like to be tied down to one location or follow a specific path. It’s almost like that the same thing is in different places at the same time. It’s crazy to think that something even as small as an atom could potentially be in multiple places at the same time. What you do in one place can affect what happens in another place without you or anyone being there.

You might be asking why we believe these bizarre laws, for the past 75 years we’ve been using these laws to describe how an atom behaves and experiment after experiment scientists have proven these laws to be always right.

A set of physical laws called Classical mechanics all have equations to see how that specific event happens and allows us to predict an event with the utmost certainty.

Bohr believed that atoms resembled miniature solar systems; there were fixed orbits these electrons can have. When an atom is heated its electrons will become agitated, and the electron would be changing orbits. Each downward leap the electron produced lights in specific colors. Now, this model seems so inaccurate, but back then I believe he was revered for his knowledge.

The double slit experiment is so amazing. When the commentator tried to show us what exactly was the double slit experiment he was at a bowling alley. With a barrier with two slits and a sheet in the back. He showed us that there are three options the bowling ball will hit the barrier or will pass through the slits and hitting the sheet. As more and more balls pass this seems to be the case wherein the balls that make it through the barrier go to the same spot every time.

When Max Born said that electrons are a probability wave I was first confused because I knew electrons as particles, not waves. Then I heard his explanation, and it was clear. These waves that were once thought of an extended electron is not the electron itself but where the electron is most likely to be.

One quote I heard within the documentary was that “The universe is governed by probability” I couldn’t agree more. All matter in the universe are made up of atoms that are governed by probability, not certainty. In life nothing is certain, but many outcomes are probable.


Quantum entanglement like the guy said I a confusing subject even he didn’t get it in college. I was confused at first too. Quantum Entanglement is the theoretical prediction that comes from the equations of quantum mechanics two particles become entangled if they are close together and their properties become linked, even if u separate those particles sending them in opposite directions they remain entangled

Overall Quantum anything is a confusing topic to understand. It will take years at a university to start comprehending the bare minimum. However Quantum theory I believe is very real and since there is nothing to contradict that it does exist in my eyes.
