Welcome to Scholastic, the world's largest publisher and distributor of children's books and a leader in educational technology and children's media! Pretty big! Brighten up student writing with stationery , clip art, and handwriting practice pages. We know about them only from detailed mathematical models of the interior of the sun. It would take over 160 YEARS to get there! At this point, the sun can use nuclear reactions of the helium that it made earlier, and convert it to carbon. SD2: As Daedalus works, his teenage son, Icarus, lies half-awake on a thin mat.Both are gaunt and pale. The outer layers, which we can see, are the corona, the chromosphere, and the photosphere. 6–8, Subscribers receive access to the website and print magazine. Have you ever gotten a sunburn? May / June 2019. Let the sun shine in with printables and learning pages such as research report prompts, sight-word mini-books, math worksheets, weather-related activities, science projects and poems, and graphing activities. As it circles the star, instruments onboard will examine how the sun creates the solar wind. It is composed mainly of hydrogen, with about 5%, by number of atoms, of helium and heavier elements. Access this article and hundreds more like it with a subscription to Scholastic News magazine. We have not yet visited any other planets or gotten close to the sun. One way is to study the sun's spectrum — that is, break up its light with a prism. Can you tell me how deep are sunspots? Use observations of the sun, moon, and … SD3: A feather floats down through a high window.Daedalus eagerly snatches it and returns to his work. Is Earth moving away from the sun? Why doesn't the sun look like the other stars? 1-LS1-1 How plants use their external parts to survive Vocabulary: evaporate, solar power What the Sun Sees, What the Moon Sees by Nancy Tafuri Focusing on the concept of opposites, the story is told from the point of view of the sun and the moon. They "hang together" because of their gravity. It is the brightest star in the constellation Centaurus, which unfortunately we can't see from the U.S. since it is in the southern sky. All this would take many millions of years. On November 5, it’s expected to enter the sun’s atmosphere. You may have noticed that the sun seems dimmer in the morning and evening than in the middle of the day. Does the amount of fusion in the core of the sun affect temperature? Hydrogen is being converted into helium, and energy is given off. This activity teaches students about the elements that compose our vast universe, including stars, planets, comets, and more! This activity will teach students all about the moon and the role it plays in our solar system. How big is the core of the sun? The source of the sun's energy (and most other stars) is nuclear reactions that change hydrogen into helium. Watch Scholastic kids’ book trailer videos, interviews with children’s book authors, famous teen celebrity book recommendations, TV and movie trailers. We believe that the sun formed from a big cloud of gas and dust. How do scientists determine the layers of the sun? But in the morning and evening, most of the blue and green light are scattered. How hot is the sun? The sun's surface temperature is about 5,800° Kelvin (about 10,000° Fahrenheit), and Betelgeuse is roughly half that, about 3,000° Kelvin (about 5,000° Fahrenheit). How large is the sun? The probe will study the sun from the outermost part of the star’s atmosphere, called the corona. So if the amount of fusion decreased, then the energy from the sun would go down. By comparison, the earth weighs 1.3 followed by 25 zeros pounds. Then the center of the star will collapse, but only part way. How close can you get to the sun without burning? Earth and Space: The cycle and patterns of the sun, moon, and stars can be observed. SD1: In a dark room with stone walls, Daedalus crouches over a table.A few candles burn nearby, casting eerie shadows. There is no oxygen in space. Search. But the corona is 300 times hotter than the sun. No mission has ever studied it from this close—until now. ... Access this video and hundreds more like it with a FREE TRIAL to Watch & Learn Video Library. While these games are fun to play, making them is no simple process. What are other patterns of the sun? Inside the sun there are also layers, but we can't see them. Don't things need oxygen in order to burn? But that is nothing for us to worry about. Learn More . The outer part will be blown out like a balloon, and our sun will become a "red giant." Fortunately the sun has been undergoing nuclear fusion at a pretty constant rate for billions of years, and we believe that it will continue for several more billions of years. However its gravity holds it together very strongly, making it hot and dense. The surface of the sun is about 10,000 degrees Fahrenheit (5,770 degrees Kelvin). But it's still pretty hot. If the sun is so hot, why doesn't it just burn up? Some of the leftover gas and dust going in orbit around this baby sun became the planets. Captain Underpants is back in an all-new epic adventure that's the zaniest, funniest, outrageousest, and time-travelingiest yet! You could line up 109 Earths along the diameter of the sun! Tra-la-laaa! Daedalus (to himself ): Just a few more feathers, and we will be free. So the sun's weight equals 340,000 Earths! ... You are being redirecting to Scholastic's authentication page... GO BACK. Haven't signed into your Scholastic account before? So far people have circled Earth in spacecraft and the shuttle, but that is only a few hundred miles up. What is the next closest star to Earth besides our sun? We are still not sure where the loops of magnetic field come from, except that they come up from inside the sun. Safe in the Summer Sun. It is also the source, one way or another, of nearly all the energy we use on the earth. Scientists have examined the different elements on earth, so we are able to figure out what kind of gas, say hydrogen, gives rise to which dark lines. The sun's core is extremely hot — about 27 million degrees Fahrenheit (15 million degrees Kelvin). It is moving (the other stars are too) in a huge circle around the center of the galaxy. It turns out that every element has a unique set of dark lines, like fingerprints. Somehow the strong magnetic fields in the sunspots work to reduce the amount of light coming from inside the sun through the spot, so it is cooler than the surrounding surface of the sun and looks darker. The outer planets would probably have their clouds burned away. So our sun is kept in its path in our galaxy by the gravity of all those other stars. This field changes strength throughout the solar cycle, an 11-year pattern when the sun’s energy and magnetic field ebb and flow. The sun's core is extremely hot — about 27 million degrees Fahrenheit (15 … The Sun’s outermost layer, the corona, is only visible to the naked eye during a total solar eclipse! Toggle navigation. So it will run out of fuel some day — fortunately for us it won't be for a LOOOONG time. The surface of the sun is about 10,000 degrees Fahrenheit (5,770 degrees Kelvin). The air scatters light, but it scatters blue and green light the most. Let's drive 65 miles per hour. Learn More . For comparison, the sun is 93,000,000 miles away — much, much further than the moon. The sun doesn't burn up because its source of power is nuclear energy. We can use them to figure out what the sun and stars are made of. The spacecraft will be equipped with a high-tech heat shield to protect it from the region’s searing 2,500-degree-Fahrenheit temperatures. Then it would get very cold and dark here! Gravity will take over, and all the matter in the star will collapse to a point. Elementary science videos for every discipline from SuperScience magazine, using current events to engage your STEM classroom Then the white dwarf will slowly give off its heat, becoming dimmer and cooler, until eventually all that would be left is a star cinder. If the sun were to run out of energy, it would quit putting out its light. That is correct, because some of the light has been scattered away. Sign in to Your Account. That's right here on earth with the atmosphere to protect you. Earth (and we) are about 93,000,000 miles from the sun. That might seem like a huge distance, but it’s closer than any spacecraft has come before. TM ® & © 2016 Scholastic Inc. All Rights Reserved. How close have people gotten to the sun? The sun is a massive, swirling ball of gas and energy. Temperatures usually drop as you move away from a heat source. The outer layer is called the corona. It is a dim, cool star, but happens to lie a little closer to us than the other two. They also show us how hot the gases are. What we call the core of the sun is the inner part where the nuclear energy is released. SL.1.2 Discuss a video; RI.1.1 Key details; RI.1.4 Vocabulary; RI.1.5 Nonfiction text features; RI.1.10 Read and discuss first-grade texts Science Focus: The sun; States of matter Next Generation Science Standards: 1-ESS1-1. The Sun is the star of our solar system—and a great subject to light up the learning! All these methods show us that the sun's surface is about 10,000 degrees Fahrenheit! Scientists say the mission could provide new insight into the sun. The following questions were answered by astronomer Dr. Cathy Imhoff of the Space Telescope Science Institute. When the sun formed, it formed from a cloud of gas. The sun has a LOT of hydrogen. Introduce and reinforce science topics with videos, slideshows, step-by-step tutorials, and other activities. That is still pretty big! In space, you would have no protection from the sun's ultraviolet light (on earth the ozone layer protects us). Step 3: Tell students that it is important to avoid direct exposure to the sun during peak hours, which are between 10 a.m. and 3 p.m. Quick Tip to Share: If students see that the length of their shadow is shorter than they are tall, they need protection from the sun. If you take blue and green away from white, you get orange and red. Weather patterns and seasonal changes can be observed and can affect daily activities. Students learn about sun safety and identify objects that start with the S sound. A rainbow is a spectrum created when sunlight goes through raindrops, which act as little prisms. This stream of charged particles can disrupt technology on Earth. As you watch the video, listen for these important words. In the middle of the day, the sun seems white because not that much blue light is scattered. ... Access this video and hundreds more like it with a FREE TRIAL to Watch & Learn Video Library. It has been in orbit at about the same distance for a long, long time or life would not have survived here. No obligation or credit card is required. Children will identify and observe ways that the sun affects Earth’s surface. To find out why, the Parker Solar Probe will become the first spacecraft ever to plunge into the sun’s atmosphere. In about five billion years, the sun will run out of energy. The sun rises and sets every day. Fortunately the sun is too small to become a supernova. Studying the Sun provides information about the galaxy and beyond. This activity will uncover what causes the changes we associate with our favorite seasons. And no, the whole galaxy wouldn't be sucked up. Readers will see how large teams of specialized workers come together to design, plan, and program today's cutting edge video … Are sunspots like magnets? The gas that collected at the center got hot from all the other gas falling on it. But strangely, parts of the sun’s atmosphere are much hotter than its surface. The sun rises and sets every day. Earth is only about 8,000 miles across. This is the source of the energy that we see as light from the sun. I think they are fairly shallow (not as deep as they are wide). No, I don't think Earth is moving away from the sun. If the sun became a supernova, the explosion would probably destroy the planets. 9–12. The sun is about 860,000 miles in diameter. The nearest star other than the sun, Alpha Centauri, is over 200,000 times farther away! It takes 80 years for the two stars to orbit each other. Because that is all the blue sunlight that the air has scattered! This important star impacts our daily lives, from providing the necessities of life to affecting our means of communication. Why is the sun orange in the morning and bright white in the afternoon? So it will affect only what is nearby, just like the star, except that if you get too close, zoom down the hole! The energy and light from the sun come from nuclear reactions deep inside the sun that occur at incredibly high temperatures millions of degrees! Next Generation Science Standards: K-PS1 Energy. Actually the sun is very much like the other stars. Our moon plays a vital role in sustaining life on Earth. The sun is in different positions in the sky throughout the day. For a star like our sun, these forces are in balance. What causes seasons and why are seasons not the same everywhere? This will enable the probe to come within nearly 4 million miles of the sun. First, let me assure you that the sun is not going to blow up any time soon! Toggle navigation. With advanced HD graphics, motion controls, and 3-D images, video games have come a long way since their earliest days. If you look at the sun when it is first rising in the morning or setting in the evening, it is passing through more of the earth's atmosphere. We know that the sun is about 4.5 billion years old, and we compute that it has about another five billion years to go before it runs out of hydrogen. A black hole still has the same gravity as the star that made it. Access this video and hundreds more like it with a FREE TRIAL to Watch & Learn Video Library. Most of what the universe is made of is gas — mostly hydrogen gas. Alpha Centauri consists of two stars in orbit around each other. Videos … Although this may sound pretty crazy, we think we have found black holes at the centers of some galaxies! NASA, the U.S. space agency, launched the probe in August. When they get old, they will go through similar (although more complex) changes. That may seem mighty hot, but it is even hotter deeper inside the sun. They give us our best "guess" of what is going on inside the sun. That would be the double star Alpha Centauri. When the sun becomes a red giant, it will be a whole lot hotter in the solar system! Anything that hot will glow and give off light, and that is why the sun is bright and looks like it is on fire. There is a third star, called Proxima Centauri, which may be in orbit around the other two stars. How far away are we from the sun? Probably the surface of the sun would be cooler. Near that point, the gravity is so strong that even light can't escape. May / June 2018. Arrow in the Sun: A Pueblo Indian Tale by Gerald McDermott An adaptation of the Pueblo myth about the how the Lord of the Sun came to the human world. On the final leg of its journey, the probe will fly through the sun’s corona. How hot is the sun? Traveling at nearly 450,000 miles per hour, it … The Sun, the central body of the solar system and the Earth's closest star, is an immense sphere of glowing gas 1.39 million km (860,000 mi) in diameter at an average distance from the Earth of 149,591,000 km (92,960,000 mi).

There are fewer hours of sunlight in the summer than in the winter. This energy generates an area of attractive and repulsive forces called a magnetic field. When the magnetic field is at its strongest, it pulls the sun inward. What are other patterns of the sun? Thus the name Proxima. The temperature is about 8,000 degrees Fahrenheit in the spot, and about 10,000 degrees at the surrounding surface of the sun! Toggle navigation. In the center of the star, there are tremendous temperatures (12 million degrees!) Our galaxy is composed of billions of stars. Have you seen a picture of a spiral galaxy? Search. We think that there may be big black holes in the center of many galaxies, but they are still not big enough to do that. The loop, which has a north pole and a south pole like a magnet, somehow keeps that part of the sun's surface from being quite as hot as the rest, making it look dark compared to the rest of the sun. Years ago NASA astronauts went to the moon, which is about 250,000 miles away. Weather patterns and seasonal changes can be observed and can affect daily activities. ... the sun. What is going to happen to the sun? If the sun blows up, what effect will it have on the other planets? We can use the techniques I described above to measure their temperatures. We test these models to see if they accurately represent how the sun looks and behaves. To find out why, the probe is flying through the corona to study it up close. The sun is, one way or another, the source of energy for all of us. Not very close! Where the sky meets the land is called the __________. How do you measure how hot the sun is if you can't get that close to measure? Sunspots are formed because of loops of magnetic fields in the sun. The sun weighs 4.4 followed by 30 zeros pounds! The hotter something is, the more light it gives off in the blue compared to the red. How did the sun form? They are nearly twins, and are also very similar to our sun. The probe is also studying the sun’s atmosphere, the layers of gas around the sun. That is why it is a BLACK hole — no light. The sun is in an orbit in our galaxy. The core is about one-fourth the size of the sun, or about 200,000 miles across. The surface will look red and will be a little cooler than it is now, but it will grow large — it will probably expand all the way out to the orbit of Mercury. The History of Sunscreen. But it is much closer. How heavy is the sun? pollen. We think that in about 4.5 billion years, the sun will run out of hydrogen in its center. It’s about 93 million miles from Earth, on average. Cancel. Academic Standards Reading Objective: Children will learn and write about sun, water, and bike safety rules. TM ® & © 2020 Scholastic Inc. All Rights Reserved. Download the PDF from here. Always check with your parents before giving out information about yourself, entering a contest or sweepstakes, or buying anything online. That may seem mighty hot, but it is even hotter deeper inside the sun. The cloud was dark and cold, and its gravity caused it to fall together. Students learn about how animals keep safe from the sun and read a diagram of the skin. That is because of the tremendous pressure of the weight of the sun pressing down on the core — equal to 333,000 Earths. You are being redirecting to Scholastic's authentication page... Access this video and hundreds more like it with a FREE TRIAL to Watch & Learn Video Library. Why is the sky blue? Its diameter is about 860,000 miles. Videos (1) Games ... Children will describe sun safety throughout history and contrast it with sun safety today. That energy keeps the entire sun hot, although at the surface it is ONLY about 10,000 degrees Fahrenheit. A sunrise happens ______________________. It will probably vaporize Mercury, and Venus and Earth would be charred. Another way is to look at sunlight and measure how much light is in the blue part of the spectrum, in the yellow, in the red. The probe’s high-tech heat shield can withstand temperatures as high as 2,500 degrees Fahrenheit. To give you an idea about how far that is, suppose we could build a highway and drive a car to the sun. No obligation or credit card is required. How does the sun get its gases? These engaging resources, including printable lesson plans, STEM activities, Sun worksheets, science projects and passages, research and study tools, and educational crafts will make learning about the Sun totally fun! A star can exist because the heat it generates inside, due to nuclear reactions, pushes outward, but this is balanced by its gravity, which pulls inward. 1-ESS1-1 Patterns of the sun. No obligation or credit card is required. We think that a really big star, once it uses up all its nuclear fuel, will collapse and nothing can stop it. The amount of nuclear fusion that happens inside the sun is the source of all the energy we get from the sun. And it would DEFINITELY get cooler on the earth. It takes about 200 million years for it to go around once! During its seven-year mission, the solar probe will orbit the sun 24 times. If you could go into space without a spacesuit, you would get burned badly by the sun. If there is no oxygen in outer space, how does the sun burn? We think that only really massive, big stars can become black holes. If we do this with a special device called a spectrograph, we can see that there are thin dark lines throughout the sun's spectrum. We believe that is what the Milky Way looks like. When it runs out of nuclear reactions that can occur in the center, the sun will not be able to make much energy. That is why it is red — red stars are cooler than the sun, blue-white stars are hotter. If we put the sun at that distance, it would look just like Alpha Centauri! So it will collapse, but we think that it will become a "white dwarf" — a small but hot star that would be only about the size of the earth! But if a star had planets, they could probably continue in their orbits if nothing else changed. But that is it. Then how can the sun be burning? No obligation or credit card is required. {{currentQuestionNumber}} of {{totalQuestions}}. (That would take our car 1.5 years to drive across!) The probe will orbit the sun 24 times during its seven-year mission. But when a very massive star collapses, its gravity can be so great that it will compress its mass to a point — a black hole. In pounds, that is 9 followed by 29 zeros! The answer to that is that the sun isn't burning the way we usually think of things. The cycle and patterns of the sun, moon, and stars can be observed. View not found. Why doesn't the sun drift off into another galaxy? What is the temperature of the sun's core? The sun is the fiery star at the center of our solar system. When nearly all the gas and dust had fallen together, the center became very hot and very dense — our sun. Now that's a heavy question! ...
