Grade 2 Mathematics Place Value

Alright, Isti — here’s a longer and more detailed English version of the Isaac Newton text, still written at a level that’s accessible for Grade 4 students, but rich enough in information to meet PISA literacy expectations and EF A2-level vocabulary. I’ve kept sentences short, clear, and with explanations for new concepts so it’s easier for young learners to follow, while still including both famous facts and lesser-known stories. ⸻ Isaac Newton: The Man Who Changed the Way We See the World A Boy from a Small Village Isaac Newton was born on January 4, 1643, in Woolsthorpe, a small village in England. His life was not easy. His father died before he was born. When he was just a few months old, his mother remarried and left him to live with his grandmother. Isaac missed his parents, but he kept himself busy by making things and exploring the world around him. As a child, Isaac liked to build models and machines. He made a small windmill that could turn with the wind. He built a water clock that told the time by dripping water into a container. He even made a sundial — a clock that tells the time by using the shadow of the sun. 💡 Did you know? The sundial marks that Isaac carved as a boy can still be seen today on the wall of his old house. ⸻ School and Curiosity When Newton first went to school, he was not the top student. At first, he did not pay much attention in class. But one day, another boy teased him for not being smart. Newton decided to study hard to prove him wrong. Soon, he became the best in his class. Isaac loved asking questions. He wanted to know how and why things happened. He enjoyed watching the stars at night and thinking about how the world worked. ⸻ The Falling Apple and Gravity One of the most famous stories about Newton is the falling apple. One afternoon, Isaac sat in his mother’s garden and saw an apple drop from a tree. This made him think: “Why does the apple fall straight down? Why doesn’t it fly up into the sky?” From this question, Newton began to think about gravity — an invisible force that pulls objects toward each other. Gravity is what keeps our feet on the ground. It’s also what keeps the Moon moving around the Earth and the planets moving around the Sun. 💡 Fun fact: The apple did not hit Newton’s head. That’s just a story people made up later to make the tale more exciting. ⸻ Newton’s Three Laws of Motion Newton studied movement and wrote three important rules: 1. Objects stay still or keep moving unless something makes them change. • Example: A ball will not roll unless you push it. 2. The bigger the push, the bigger the movement. • Example: If you kick a ball harder, it will go faster and farther. 3. Every action has an equal and opposite reaction. • Example: When you jump off a boat, the boat moves backward as you move forward. These three laws are still used today to understand how cars, rockets, and even roller coasters work. ⸻ Discoveries in Light and Color Newton also studied light. He found that white light is not just one color — it is made of many colors. He used a glass prism to split sunlight into a rainbow. This helped scientists understand how colors work. ⸻ Inventions and New Ideas Newton made a special telescope that used mirrors instead of lenses. This type of telescope made images of planets and stars much clearer. It is still called the Newtonian telescope today. He also worked in mathematics and helped create a new type of math called calculus, which is used to study changes and movement. ⸻ Strange Experiments Newton was so curious that he sometimes tested ideas on himself. Once, he put a thin needle, called a bodkin, beside his eye to see how it would change his vision. It was very dangerous, but luckily he did not go blind. 💡 Did you know? Newton also studied alchemy — an old kind of science where people tried to turn metal into gold. He never succeeded, but it showed how wide his interests were. ⸻ Later Life and Work At the age of 27, Newton became a professor at Cambridge University. He later worked for the Royal Mint, making sure coins were made safely and stopping people from making fake money. He was very strict, and some criminals were sent to prison because of his work. Newton never married. He spent most of his life reading, writing, and doing experiments. ⸻ The End of His Life Isaac Newton died in 1727 at the age of 84. He was buried in Westminster Abbey, a famous place in London where great people of Britain are honored. His work changed the world forever. Even today, scientists, engineers, and students still use Newton’s laws and ideas. 💬 Newton once said: “If I have seen further, it is by standing on the shoulders of giants.” This means we can make new discoveries by learning from the work of others who came before us. give 10 questions to each passage with PISA literacy standard for kid 10 years, 1. Nikola Tesla: The Man Who Dreamed of Lightning Born: July 10, 1856 Died: January 7, 1943 When Nikola Tesla was a boy in Croatia, he saw a flash of lightning and asked his mother, “Can we catch the light?” That question never left him. As he grew older, Tesla became a brilliant inventor, especially fascinated by electricity. He believed in a future where energy could be sent wirelessly through the air—like music through the radio! Tesla invented the alternating current (AC) system, which became the foundation of modern electricity. At the time, Thomas Edison promoted direct current (DC), and the two men had a fierce competition. Many laughed at Tesla's bold ideas, but he never gave up. He dreamed of wireless communication, flying machines, and even free energy for everyone. Though he died alone and poor, today the world honors his vision. Think About It: Why do you think people didn’t believe Tesla at first? What can we learn from Tesla’s courage to dream big? 2. Charles Darwin: The Man Who Studied the World’s Weirdest Creatures Born: February 12, 1809 Died: April 19, 1882 When young Charles Darwin got on a ship called HMS Beagle, he didn’t know he would change science forever. He sailed around the world for five years, collecting plants, animals, and fossils. On the Galápagos Islands, he noticed something curious: finches had different beaks depending on their island. Why? Darwin’s observations led him to write the theory of evolution by natural selection. It explained how animals adapt and survive. But his ideas shocked many people because they seemed to challenge religious beliefs. Despite the controversy, Darwin continued his work. His book On the Origin of Species changed how we see life on Earth. Think About It: Should scientists share their ideas even if they go against what others believe? How did traveling help Darwin make new discoveries? 3. Marie Curie: The Woman Who Glowed in the Dark Born: November 7, 1867 Died: July 4, 1934 Marie Curie was born in Poland at a time when girls were not allowed to study science. But that didn’t stop her. She moved to France, worked day and night, and discovered radioactivity, a powerful energy hidden inside atoms. She and her husband, Pierre Curie, found two new elements: polonium and radium. She became the first woman to win a Nobel Prize, and the only person to win in two different sciences: physics and chemistry. Even when Pierre died in an accident, Marie continued their work. Her discoveries helped doctors treat cancer—but working with radioactive materials also harmed her health. She died from radiation exposure, but her legacy lives on. Think About It: What challenges did Marie Curie face as a woman in science? Why is it important to balance discovery with safety? 4. Galileo Galilei: The Star Watcher Who Defied the Church Born: February 15, 1564 Died: January 8, 1642 Galileo loved looking at the stars. He built one of the first powerful telescopes and made stunning discoveries: mountains on the Moon, moons around Jupiter, and that the Earth orbits the Sun—not the other way around. This idea, called heliocentrism, went against the teachings of the Church. He was put on trial and forced to say he was wrong. But he wasn’t. He spent his last years under house arrest, quietly writing. Today, Galileo is called the father of modern science for daring to question what others blindly believed. Think About It: Why do you think Galileo was punished for telling the truth? Should science always follow evidence, even if it goes against powerful beliefs? 5. Isaac Newton: The Man Who Asked “Why?” When an Apple Fell Born: January 4, 1643 Died: March 31, 1727 One day, an apple fell from a tree, and Isaac Newton began to wonder: Why did it fall down, not sideways or up? This simple question led to his theory of gravity. Newton also invented calculus, described the laws of motion, and changed physics forever. But Newton wasn’t just a genius—he was curious, quiet, and often worked alone. He believed everything in nature followed rules, and it was our job to discover them. Thanks to him, we understand how planets move, how rockets launch, and why you fall when you trip. Think About It: How did Newton’s curiosity lead to great discoveries? Do you think working alone helped or hurt Newton? 6. Ada Lovelace: The First Computer Programmer Before Computers Existed Born: December 10, 1815 Died: November 27, 1852 Ada Lovelace was the daughter of the famous poet Lord Byron, but she didn’t love poetry—she loved numbers! At a time when girls were expected to sew, Ada studied mathematics. She met Charles Babbage, who designed an early computer called the Analytical Engine. Ada imagined the machine could do more than just math—it could create music, art, and even write! She wrote what is now considered the first computer program, long before real computers were built. Think About It: How did Ada imagine something that didn’t exist yet? Why do we call her a pioneer in technology? 7. Albert Einstein: The Man Who Brought Time and Space Together Born: March 14, 1879 Died: April 18, 1955 Albert Einstein wasn’t always a good student. In fact, his teachers thought he was slow. But Einstein thought deeply. He asked big questions like, “What if you could ride a beam of light?” His theories of relativity changed how we see space, time, and gravity. He also warned the world about the dangers of nuclear weapons, even though his ideas helped create them. Einstein believed science should help people, not harm them. With his messy hair, kind smile, and brilliant mind, he remains a symbol of genius. Think About It: Can someone be bad in school but still be brilliant? Should scientists be responsible for how their inventions are used? 8. Pythagoras: The Musician Who Loved Math Born: Around 570 BC Died: Around 495 BC Long ago in ancient Greece, Pythagoras believed the universe followed numbers. He discovered the Pythagorean Theorem, a rule about triangles that helps us build houses, design computers, and navigate space. He also believed that music had math inside it—that certain notes made perfect harmony because of mathematical ratios. Pythagoras started a secret school and taught his students to search for truth through numbers, shapes, and sound. Think About It: Why do you think Pythagoras saw math in everything? How does music relate to math? 9. Rosalind Franklin: The Woman Behind the DNA Discovery Born: July 25, 1920 Died: April 16, 1958 Rosalind Franklin loved looking closely at things. She used a special machine called X-ray crystallography to photograph molecules. One of her greatest photos, called Photo 51, showed the shape of DNA, the molecule that carries life’s instructions. But her work was taken without credit. Two men, Watson and Crick, used her photo to build their famous model of DNA and won the Nobel Prize. Rosalind died young and never knew how important her work became. Think About It: Why is it important to give credit in science? What can we learn from Rosalind’s quiet strength? 10. Carl Linnaeus: The Man Who Gave Names to Everything Born: May 23, 1707 Died: January 10, 1778 Have you ever wondered why a tiger is called Panthera tigris? That’s thanks to Carl Linnaeus, a Swedish scientist who created a way to name and organize every living thing. His system is still used today in biology. Linnaeus loved nature and spent his life collecting plants, animals, and even rocks. He believed that by organizing life, we could better understand it. Thanks to him, we now have a global “dictionary of nature.” Think About It: Why is it important to name and organize living things? How does order help us understand the world?

0:01 i pasticciotti presentano Federico II di 0:05 Sveia 0:07 Nel 0:09 1186 Costanza D'Alta Villa figlia del re 0:12 normno di Sicilia Ruggero II sposò ormai 0:16 trentenne Enrico VI di Svevia figlio 0:20 dell'imperatore Federico Barbarossa che 0:23 si servì di questo matrimonio per 0:26 stringere un'alleanza politica con la 0:28 monarchia siciliana 0:31 Purtroppo non fu un'unione felice sia 0:34 perché il marito aveva 10 anni in meno 0:37 della moglie sia perché lui non aveva un 0:40 bel carattere e pare che rinfacciasse 0:44 continuamente a costanza la sua età 0:47 avanzata temendo che ciò fosse causa di 0:50 sterilità 0:52 Alla morte di Federico Barbarossa nel 0:56 1190 Enrico VI ereditò dal padre il 1:00 titolo di imperatore del Sacro Romano 1:02 Impero ma era incapace di esercitare un 1:06 buon governo nei confronti dei sudditi 1:09 normanni che vivevano nel regno di 1:11 Sicilia portatogli in dote dalla moglie 1:14 Costanza 1:16 Così nel 1:18 1994 Enrico partì per una spedizione in 1:22 Sicilia senza la moglie al seguito e 1:25 fece in modo di essere incoronato re di 1:28 Sicilia il giorno di Natale nella 1:31 cattedrale di 1:33 Palermo Lo stesso giorno Costanza che 1:36 era in avanzato stato di gravidanza e 1:39 stava viaggiando in direzione di Palermo 1:42 per raggiungere il marito si rese conto 1:44 di essere prossima al 1:47 parto Se oggi nessuno più si meraviglia 1:50 della gravidanza di una quarantenne nel 1:52 Medioevo una gestazione a quell'età 1:55 sembrava una cosa praticamente 1:57 impossibile Pertanto si erano alimentate 2:01 voci malevoli sulla vera condizione di 2:04 costanza e neppure il marito pareva 2:07 realmente convinto della gravidanza 2:09 della moglie E dato che Costanza prima 2:12 di sposarsi era stata per un periodo in 2:16 monastero circolava addirittura la voce 2:19 che nel suo grembo ci fosse 2:21 l'anticristo che secondo una leggenda 2:24 medievale sarebbe nato dall'unione di 2:26 una vecchia monaca con un 2:29 frate Così Costanza decise di fermarsi 2:33 nella cittadina di Iesi e per fugare 2:36 ogni dubbio sulla sua gravidanza fece 2:39 allestire una tenda nella piazza 2:42 centrale della cittadina 2:44 marchigiana in modo da partorire al 2:47 cospetto di tutte le donne sposate del 2:50 paese Alcuni riferirono che il giorno 2:53 successivo al parto la regina lattò 2:56 pubblicamente il piccolo che poi fu 2:59 battezzato nella cattedrale di San 3:01 Ruffino di Assisi con il nome di 3:04 Federico 3:06 Ruggero Federico per indicare la 3:09 discendenza sveva quale nipote di 3:12 Federico 3:13 Barbarossa e Ruggero per sottolineare la 3:17 discendenza normanna dal primo re di 3:20 Sicilia Ruggero 3:23 d'Altavilla A soli 3 anni il piccolo 3:26 Federico rimase orfano e fu posto sotto 3:30 la tutela di Papa Innocenzo II da cui si 3:33 affrancò a 14 anni quando divenne prima 3:37 re di Sicilia e poi re di 3:41 Germania acquisendo il nome di Federico 3:44 II congiuntamente al titolo di 3:47 imperatore nel 1220 3:50 Ma Federico era più interessato 3:53 all'Italia che alla 3:54 Germania Così stabilì la sua corte in 3:57 Sicilia a 4:00 Palermo Federico II organizzò un regno 4:04 forte e 4:05 accentrato costruendo in tutta l'Italia 4:08 meridionale vari castelli dove collocò 4:11 le sue truppe che dovevano controllare 4:14 il territorio e sedare eventuali rivolte 4:18 Vanno menzionati in particolare il 4:21 castello di Melfi in Basilicata dove 4:25 furono promulgate le famose costituzioni 4:29 melfitane una raccolta di leggi scritte 4:32 rivolte a tutti gli abitanti del regno 4:35 con cui si limitavano i poteri dei 4:38 baroni locali e si vietava il ricorso 4:41 alla vendetta personale per affidarsi 4:44 invece alla giustizia stabilita dalle 4:47 leggi 4:48 C'era poi il castello di Trani che aveva 4:51 la funzione di sorvegliare l'ingresso 4:54 alla città e al porto E infine il 4:58 celeberrimo castel del Monte 5:01 caratterizzato da un'originale pianta 5:03 ottagonale attorniata da torri anch'esse 5:07 ottagonali che fungeva da dimora come 5:10 testimoniato dalla presenza di grandi 5:13 camini Uomo colto fine giurista 5:17 Amante dell'arte della letteratura 5:20 Federico II ospitò alla sua corte 5:22 studiosi e artisti provenienti da tutta 5:25 Europa Dialogò con intellettuali arabi e 5:29 fondò l'Università di Napoli che ancora 5:32 oggi porta il suo 5:35 nome Con l'editto di Salerno regolamentò 5:38 per la prima volta la professione del 5:41 farmacista separandola di fatto da 5:44 quella del medico scrisse anche un libro 5:48 un manuale sulla falconeria e sull'arte 5:52 venatoria chiamato de Arte venandi cum 5:57 avibus ossia l'arte di cacciare con gli 6:01 uccelli che fu uno dei primi manoscritti 6:04 con disegni a tema 6:08 naturalistico In una nota alla sua morte 6:11 il monaco Matteo Paris lo chiamerà 6:14 stupor Mundi cioè stupore del mondo Un 6:19 appellativo che racchiude l'essenza 6:21 della sua inestinguibile curiosità 6:25 intellettuale che lo portò ad 6:27 approfondire la filosofia l'astrologia 6:30 la matematica l'algebra la medicina e le 6:34 scienze naturali ha al punto da 6:37 impiantare a Palermo persino uno zoo 6:40 famoso ai suoi tempi per il gran numero 6:43 di animali esotici che conteneva anche 6:46 un 6:47 elefante I rapporti col papo però non 6:51 furono idiaci 6:53 Sia Papa Onorio II che Gregorio Io detto 6:57 anche il Papa Guerriero lo costrinsero a 7:00 intraprendere una nuova crociata in 7:02 Terra Santa minacciando di scomunicarlo 7:06 qualora non l'avesse 7:08 fatto Così dopo tanta insistenza da 7:11 parte del papato Federico si mise in 7:13 viaggio per la Terra Santa 7:16 Giunto in Oriente però non mosse guerra 7:19 ai musulmani ma preferì stringere 7:22 accordi con il sultano d'Egitto 7:25 ottenendo il controllo della città di 7:27 Gerusalemme e una tregua di 10 anni 7:32 Si trattava di conquiste importanti dal 7:34 punto di vista diplomatico ma al suo 7:37 ritorno Federico II fu accusato 7:40 duramente di essere sceso a patti con 7:42 gli 7:43 infedeli Nel suo programma di governo 7:47 Federico II era intenzionato a 7:49 riaffermare la sua autorità sui comuni 7:52 del Nord Italia fatto che preoccupava il 7:56 Papa il quale temeva il rafforzamento 7:59 del potere imperiale anche a nord dello 8:02 Stato Pontificio già confinante a sud 8:05 con il Regno di Sicilia 8:08 In pratica il Papa si sentiva 8:11 schiacciato sia a nord che a sud 8:14 dall'imperatore Così Papa Gregorio Io 8:18 appoggiò alcuni comuni che si riunirono 8:20 nella Lega Lombarda e che furono detti 8:24 guelfi A questi si contrapposero i 8:27 comuni ghibellini che decisero di 8:30 schierarsi a sostegno 8:33 dell'imperatore Iniziò così una 8:35 lunghissima contesa che avrebbe 8:38 dilaniato le città 8:41 italiane Tutto 8:43 chiaro ciao e al prossimo 8:49 video Se questo video ti è piaciuto ti 8:52 chiedo di fare mi piace cliccando 8:53 sull'icona qui sotto Per me è molto 8:55 importante quindi grazie in anticipo se 8:57 lo farai Per essere informato ogni volta 8:59 che pubblico un nuovo video ricorda di 9:01 cliccare anche sul grande pulsante rosso 9:02 Iscriviti e sulla campanella di fianco 9:05 [Musica]
