The Great Albert Einstein… in a cartoon
Ah! Yes. Albert Einstein. The famous scientist and mathematician who’s last name I can never spell correctly! Yes. Today, I’m going to teach you about Albert Einstein. But not about him. I’m going to talk about his refrigerator.
What?! Albert Einstein invented a refrigerator! Yes. Why yes he did.
The Einstein–Szilard, or Einstein refrigerator is an absorption refrigerator that has no moving parts, operates at constant pressure, and requires only a heat source to operate. Pretty cool, right?
Did you know? Albert Einstein was fascinated by what happened to a Berlin family who had been killed when a seal in their refrigerator failed and leaked toxic fumes into their home. Pretty strange reason to get fascinated, am I right? (But no one came blame Einstein. He changed our lives!)
Einstein’s refrigerator was patented in the 1930s and doesn’t use greenhouse gases and can be used without electricity! Do we still use it now? I have no idea!
Isaac Newton Himself
Calculus. You might’ve heard it from someone, you might know it as some kind of math, but you might not know that Newton discovered it!
Many people know Isaac Newton for his discovery about his three law’s of motion, but he also invented calculus! I bet you didn’t know that! It impacted the world when he invented calculus in 1665. We take this for granted nowadays, but what Newton did hundreds of years ago is astonishing, considering now, many people take ages to learn it!
Calculus has uses in physics, chemistry, biology, economics, pure mathematics, all branches of engineering and much more!
Newton’s focus on gravity and laws of motion are linked to his breakthrough in calculus. Newton started by trying to recount the speed of a falling object. When he did, Newton found out that the rate of a falling object increases every second, but there was no currently existing mathematical explanation for this!
Newton immediately started working on this, and he figured out that when using calculus, he could explain it! So this is how Isaac Newton discovered calculus.
Okay. So who is this Ohm guy? His full name is Georg Ohm. (And yes. It’s spelled Georg. That’s not a typo. He has such a strange spelling name in my opinion. No offense Ohm!)
He was born on March 16, 1789, in the university town of Erlangen, Bavaria. His little brother, Martin Ohm, also became a famous mathematician! Johann Wolfgang Ohm, his father, was a locksmith. Maria Elizabeth Beck, his mother, was a daughter of a tailor. She died when Georg was ten.
“Ohm’s Law states that the current passing through a conductor is proportional to the voltage over the resistance,” says ducksters.com.
This may sound very confusing. I’m a little bit confused myself! But it can be written in a simple formula: I = V/R. I is currents in amps. V is voltage in volts. And R is resistance in ohms.
Voltage divided by current is resistance. Resistance times current equals voltage. Just like math. I don’t like math.
Hey! Ohm is not a thing. He’s a person! But an ohm CAN be defined as “an electrical resistance between two points of a conductor,” as said by Wikipedia.
So I guess when you say “ohm”, it could mean a person or a thing! Kinda like a noun. Haha.
Yes. Atoms. But what are atoms? Well, they make up everything! They’re made up of 3 teeny weeny particles: the proton, the neutron, and the electron.
The biggest idea from all time, is that stuff, is made, from atoms.
When the theory was proposed, it sounded absolutely insane! Nobody believed it! Now, nobody would run around shouting “Atoms are just a theory!” But not so long ago, people did do that. And you wanna know who settled it for good? Einstein.
Yes. The amazing scientist and mathematician. Of course it’s Einstein. Atoms had been theorized for a long time by the 20th century, but only when Einstein proved its existence in 1905 with amazing math skills (which I will never have), is when the matter was really settled.
Here’s the story about how the ancient Einstein found out about atoms. But it first started with a botanist.
In 1827, a botanist named Robert Brown was looking at pollen grains in water through a microscope and he noticed that they moved around even when there was no movement in the water to cause it! It was a mystery that lasted a really long time.
Until… In 1905, when Einstein theorized that this incident was caused by as to-be-proven atomic particles actually hitting into the grains of pollen. He wrote some fancy complicated math equation, proving that his theory predicted this motion almost perfectly, so everyone had to agree that yes, tiny bits of matter were really smacking into the pollen, and so atoms, had to exist.
Yes, a very interesting story indeed. I wonder how complicated Einstein’s math equation really was.
I-Beams. When you first hear it, you might think, “Oh, it’s a beam that’s shaped like an I!” Well, you are correct! I-Beams are used in many places. I-Beams are used in the structural steel construction industry. They are often used as the main support for trusses.
(Trusses means triangles.)
For our project this week, we’re supposed to make 2 beams: One of them is an I-Beam, and the other one is a beam of our own design.
On 9/23, I built my 2 I-Beams. One of them was longer, and the other one was shorter. I made both of them in the Zoom for extra help. (At the Zoom, I was eating my lunch, dumplings, but the teacher couldn’t see me. Tee-hee! But later, my longer one broke. Whoops.)
The second part of the project was to film a Flipgrid (an app) video, and you’re supposed to show you testing your beam.
My I-Beam withstood eight pounds before it collapsed. Pretty good, if I do say so myself. 🙂
I think that this project was super fun. You know, I actually made another beam to use as my main beam because my main beam was too short.
The first day of actually going to Scarsdale Middle School in person was really intimidating. I was so nervous when my mom dropped me off. She said: Don’t worry! You’ll be okay. Everyone is nervous on their first day. I knew that, but still, I was scared. But who isn’t? It’s a big transition from elementary school to middle school. The building is bigger, there’s more classes, more teachers, and most importantly, more homework. (This is what I’m most afraid of.)
I walk into the doorway on the upper circle, and ask a lot of teachers for help to find my homeroom. Finally, I get to my homeroom/science room. Dr. Williams was at his desk, and some other people were already there.
“Go to a desk with an iPad case on it.” Dr. Williams said, so I sat at the front row. How do I put on my iPad case? I wondered while awkwardly putting some of my things on my desk. I awkwardly looked around at all the people around. Wow, there are so many boys! How am I gonna survive?
Soon, class started. Dr. Williams introduced everyone, he helped me with putting on my iPad case (he said his thumbs are still sore from putting on the case), and I really enjoyed the class.
Next, we had technology. It was really interesting! Mr. Calvert talked about the Dee Bridge Incident, the 1986 Challenger Explosion, the Titanic, and how they all had the incident not because of the design, but because the choice of material.
Social Studies was a bit different. Ms. Castiello was zooming in from Zoom. It was a little bit echo-y because we also joined the Zoom from our iPads, but it was a really good class!
At the end of the day, I was so sad that I had to go home! School was already over! So sad 😥. (Yes, yes. I know. I enjoy school. Don’t judge. Humph.) I saw some of my friends while waiting for my mom to pick me up. We talked a little, but then my mom called me and I left.
In this blog post, I’m going to be talking about my Ignite. What is an Ignite? An Ignite is a five minute presentation on a topic. And think about it as a story. You would tell a story on, let’s say, gymnastics, if you like gymnastics. My presentation is one minute and forty five seconds long. I was given the choice to do whatever topic I want. So I chose Greek Mythology. I think doing an Ignite is fun, except presenting it. I always get nervous. This is a practice Ignite, because after this Ignite, I’m going to do an official one on Colonial America, but that’s later. In the process, I wrote stuff in a script, and then, after that, made a slideshow with pictures, no words. It’s because I’m going to be talking, so if I put words on the slideshow, then the audience would focus on the words, and not me. In the speaker notes, I put in my script for each slide. In total, there are seven sides, and an eighth slide that says “Time is up!” There’s an eighth slide that says “Time Is Up”, so that you wouldn’t keep talking. Each slide would stay up for fifteen seconds, so I would have to talk for fifteen seconds. Originally, there’s supposed to be twenty six slides. In the script, there are four sections: time, picture, slides, and words. In the beginning of the project, I was super nervous. But now, I’m mostly not nervous, except on the part that I have to present it to twenty three people, plus, their parents. But I love doing this project because it’s super fun and exciting. Mr. Casal kept on teaching me what to do, so that’s how I got to here.
I researched about China. My teacher put a packet together and that’s where I wrote my notes. I got information from the Heathcote library databases, from books and from my own knowledge to study the different cultural universals of China. The cultural universals are: Politics. Social Aspects, Economics, Beliefs and Cultural Arts. After I researched enough on each cultural universal, I put together a comic book titled “The Wonders of China.” My favorite part of this project is making the character in Google Drawings. The thing I found challenging was copying and pasting my character into the slides.
What we did today that worked was that we got the magnets on the track to line up with the magnets on the train. Before we figured out that we had to do that, our magnets on our track attracted with the magnets on the train. We needed like poles and since the magnets are not labeled, we needed to find a system. So we marked the tape on the magnets with stars so we would know which side would repel and which side would attract. We also got the train to levitate a little higher with some more strip magnets.
What we did today that failed was that we tried to put some magnets on the side the train was going to on the attract side and a few magnets on the beginning of the track on the repel side. We thought the magnets on the repel side would give a push to the train and the train would get attracted to the magnets on the attract side so the train would move there, but that didn’t work. I learned from my failure that we needed stronger magnetic forces.
My goals for the next session is to get the train to move to the other side with a slight push and for the train to not tip over.
This is my group with our maglev model.
The assignment was to make a book that you’re an expert on. My teacher also told us that expert books aren’t just facts, facts and more facts. There are also statistics, quotations, observations, lists, labels and many more! I used a lot of tools for this assignment. Before I typed a lot of this, I thought I was so behind. But then when I went home to type, I felt so much better. This book took a really long time to make. I wrote this book because I knew a lot about Chinese New Year. At first I wanted to write about China but then I realized that just because I went to China a lot of times doesn’t mean that I will know a lot about China. The chapter names were kind of easy. My chapter 3 was first going to be “Christmas V.S. Chinese New Year” But then, after an assembly, my teacher suggested to do “New Year’s Day V.S. Chinese New Year” instead of “Christmas V.S. Chinese New Year.” One time, when my teacher said that we had to find some vocabulary words, I couldn’t find any vocabulary words. And then, at school, I just magically found the word resolution to add in my book. Now I have five vocabulary words in my glossary. I’m going to give credit to a classmate because when my teacher suggested traditions, he said: “Why don’t you do Chinese New Year?” I’m also going to give credit to Pebble Go. I used some facts from there. I learned also not to use ‘I’ in my story. It’s not a personal narrative. For text features, I used a map in chapter one and I used two labels in the introduction. I used a mini story in chapter four. For my introduction, I got the ‘Happy Chinese New Year’ part from this article except the article said ‘Play ball’ instead of ‘Happy Chinese New Year.’ The technology part was pretty fun and cool. Especially the linking part. And the switching slide part. Also, I learned that you don’t do a background. Thank you, Mr. Casal! So that’s how I got this good in my book.
My book is called Chinese New Year. I hope you’ll enjoy it! And here it is…
