scholastic video about the sun

But it's still pretty hot. The surface of the sun is about 10,000 degrees Fahrenheit (5,770 degrees Kelvin). All these methods show us that the sun's surface is about 10,000 degrees Fahrenheit! The sun is in different positions in the sky throughout the day. Then it would get very cold and dark here! You may have noticed that the sun seems dimmer in the morning and evening than in the middle of the day. The History of Sunscreen. That may seem mighty hot, but it is even hotter deeper inside the sun. 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. Traveling at nearly 450,000 miles per hour, it … It will probably vaporize Mercury, and Venus and Earth would be charred. That may seem mighty hot, but it is even hotter deeper inside the sun. 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. NASA, the U.S. space agency, launched the probe in August. Then how can the sun be burning? SD2: As Daedalus works, his teenage son, Icarus, lies half-awake on a thin mat.Both are gaunt and pale. That is correct, because some of the light has been scattered away. While these games are fun to play, making them is no simple process. But it is much closer. We believe that is what the Milky Way looks like. 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. Welcome to Scholastic, the world's largest publisher and distributor of children's books and a leader in educational technology and children's media! If the sun were to run out of energy, it would quit putting out its light. Fortunately the sun is too small to become a supernova. Use observations of the sun, moon, and … 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. Actually the sun is very much like the other stars. If we put the sun at that distance, it would look just like Alpha Centauri! 1-ESS1-1 Patterns of the sun. Learn More . It is moving (the other stars are too) in a huge circle around the center of the galaxy. Weather patterns and seasonal changes can be observed and can affect daily activities. How big is the core of the sun? You could line up 109 Earths along the diameter of the sun! In pounds, that is 9 followed by 29 zeros! We can use them to figure out what the sun and stars are made of. The probe will study the sun from the outermost part of the star’s atmosphere, called the corona. In space, you would have no protection from the sun's ultraviolet light (on earth the ozone layer protects us). It turns out that every element has a unique set of dark lines, like fingerprints. Earth is only about 8,000 miles across. There is no oxygen in space. We think that in about 4.5 billion years, the sun will run out of hydrogen in its center. Students learn about how animals keep safe from the sun and read a diagram of the skin. Access this video and hundreds more like it with a FREE TRIAL to Watch & Learn Video Library. Toggle navigation. The probe will orbit the sun 24 times during its seven-year mission. Academic Standards Reading Objective: Children will learn and write about sun, water, and bike safety rules. But if a star had planets, they could probably continue in their orbits if nothing else changed. 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! Inside the sun there are also layers, but we can't see them. and pressures that help produce nuclear fusion. The gas that collected at the center got hot from all the other gas falling on it. The nearest star other than the sun, Alpha Centauri, is over 200,000 times farther away! We test these models to see if they accurately represent how the sun looks and behaves. Toggle navigation. In the middle of the day, the sun seems white because not that much blue light is scattered. Gravity will take over, and all the matter in the star will collapse to a point. Captain Underpants is back in an all-new epic adventure that's the zaniest, funniest, outrageousest, and time-travelingiest yet! They "hang together" because of their gravity. And it would DEFINITELY get cooler on the earth. The Sun is the star of our solar system—and a great subject to light up the learning! Cancel. 9–12. 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! This activity will uncover what causes the changes we associate with our favorite seasons. Learn More . Why is the sky blue? This energy generates an area of attractive and repulsive forces called a magnetic field. For a star like our sun, these forces are in balance. 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. The sun is the fiery star at the center of our solar system. Learn More . 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. A black hole still has the same gravity as the star that made it. How large is the sun? Sunspots are formed because of loops of magnetic fields in the sun. But strangely, parts of the sun’s atmosphere are much hotter than its surface. Safe in the Summer Sun. That is why it is red — red stars are cooler than the sun, blue-white stars are hotter. Not very close! The surface of the sun is about 10,000 degrees Fahrenheit (5,770 degrees Kelvin). Access this article and hundreds more like it with a subscription to Scholastic News magazine. But in the morning and evening, most of the blue and green light are scattered. When they get old, they will go through similar (although more complex) changes. Most of what the universe is made of is gas — mostly hydrogen gas. Because that is all the blue sunlight that the air has scattered! How hot is the sun? The cycle and patterns of the sun, moon, and stars can be observed. The core is about one-fourth the size of the sun, or about 200,000 miles across. ... You are being redirecting to Scholastic's authentication page... GO BACK. How do you measure how hot the sun is if you can't get that close to measure? There are fewer hours of sunlight in the summer than in the winter. On the final leg of its journey, the probe will fly through the sun’s corona. As it circles the star, instruments onboard will examine how the sun creates the solar wind. There is a third star, called Proxima Centauri, which may be in orbit around the other two stars. Anything that hot will glow and give off light, and that is why the sun is bright and looks like it is on fire. This important star impacts our daily lives, from providing the necessities of life to affecting our means of communication. So it will run out of fuel some day — fortunately for us it won't be for a LOOOONG time. The sun rises and sets every day. Its diameter is about 860,000 miles. What are other patterns of the sun? The air scatters light, but it scatters blue and green light the most. Although this may sound pretty crazy, we think we have found black holes at the centers of some galaxies! I think they are fairly shallow (not as deep as they are wide). The sun is in an orbit in our galaxy. Daedalus (to himself ): Just a few more feathers, and we will be free. The outer part will be blown out like a balloon, and our sun will become a "red giant." If the sun is so hot, why doesn't it just burn up? 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). Haven't signed into your Scholastic account before? If you could go into space without a spacesuit, you would get burned badly by the sun. How heavy is the sun? {{currentQuestionNumber}} of {{totalQuestions}}. That is still pretty big! It’s about 93 million miles from Earth, on average. The source of the sun's energy (and most other stars) is nuclear reactions that change hydrogen into helium. The sun weighs 4.4 followed by 30 zeros pounds! What causes seasons and why are seasons not the same everywhere? We believe that the sun formed from a big cloud of gas and dust. How does the sun get its gases? It takes about 200 million years for it to go around once! That energy keeps the entire sun hot, although at the surface it is ONLY about 10,000 degrees Fahrenheit. (That would take our car 1.5 years to drive across!) But that is it. How far away are we from the sun? Scientists say the mission could provide new insight into the sun. 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. So far people have circled Earth in spacecraft and the shuttle, but that is only a few hundred miles up. 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. This field changes strength throughout the solar cycle, an 11-year pattern when the sun’s energy and magnetic field ebb and flow. Don't things need oxygen in order to burn? 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. What is the temperature of the sun's core? Watch Scholastic kids’ book trailer videos, interviews with children’s book authors, famous teen celebrity book recommendations, TV and movie trailers.

Access this article and hundreds more like it with a subscription to Scholastic News magazine. First, let me assure you that the sun is not going to blow up any time soon! If the sun blows up, what effect will it have on the other planets? At this point, the sun can use nuclear reactions of the helium that it made earlier, and convert it to carbon. The sun is about 860,000 miles in diameter. Our galaxy is composed of billions of stars. Next Generation Science Standards: K-PS1 Energy. To find out why, the probe is flying through the corona to study it up close. Earth (and we) are about 93,000,000 miles from the sun. No obligation or credit card is required. Have you ever gotten a sunburn? No obligation or credit card is required. It is composed mainly of hydrogen, with about 5%, by number of atoms, of helium and heavier elements. The cloud was dark and cold, and its gravity caused it to fall together. ... You are being redirecting to Scholastic's authentication page... GO BACK. Hydrogen is being converted into helium, and energy is given off. 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). How close have people gotten to the sun? Elementary science videos for every discipline from SuperScience magazine, using current events to engage your STEM classroom The sun doesn't burn up because its source of power is nuclear energy. The sun's core is extremely hot — about 27 million degrees Fahrenheit (15 … But that is nothing for us to worry about. Near that point, the gravity is so strong that even light can't escape. But the corona is 300 times hotter than the sun. SD1: In a dark room with stone walls, Daedalus crouches over a table.A few candles burn nearby, casting eerie shadows. Is Earth moving away from the sun? Subscribers receive access to the website and print magazine. You are being redirecting to Scholastic's authentication page... GO BACK. When nearly all the gas and dust had fallen together, the center became very hot and very dense — our sun. During its seven-year mission, the solar probe will orbit the sun 24 times. To give you an idea about how far that is, suppose we could build a highway and drive a car to the sun. How close can you get to the sun without burning? How do scientists determine the layers of the sun? What is going to happen to the sun? Videos (1) Games ... Children will describe sun safety throughout history and contrast it with sun safety today. The energy and light from the sun come from nuclear reactions deep inside the sun that occur at incredibly high temperatures millions of degrees! Now that's a heavy question! Weather patterns and seasonal changes can be observed and can affect daily activities. Readers will see how large teams of specialized workers come together to design, plan, and program today's cutting edge video … Why doesn't the sun look like the other stars? We think that a really big star, once it uses up all its nuclear fuel, will collapse and nothing can stop it. Studying the Sun provides information about the galaxy and beyond. View not found. So it will affect only what is nearby, just like the star, except that if you get too close, zoom down the hole! No mission has ever studied it from this close—until now. All this would take many millions of years. The sun is a massive, swirling ball of gas and energy. Alpha Centauri consists of two stars in orbit around each other. It has been in orbit at about the same distance for a long, long time or life would not have survived here. The sun is, one way or another, the source of energy for all of us. It is also the source, one way or another, of nearly all the energy we use on the earth. That's right here on earth with the atmosphere to protect you. The outer layers, which we can see, are the corona, the chromosphere, and the photosphere. The hotter something is, the more light it gives off in the blue compared to the red. A rainbow is a spectrum created when sunlight goes through raindrops, which act as little prisms. It would take over 160 YEARS to get there! Download the PDF from here. 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. With advanced HD graphics, motion controls, and 3-D images, video games have come a long way since their earliest days. 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. They are nearly twins, and are also very similar to our sun. 1-LS1-1 How plants use their external parts to survive Vocabulary: evaporate, solar power Probably the surface of the sun would be cooler. The sun's core is extremely hot — about 27 million degrees Fahrenheit (15 million degrees Kelvin). Students learn about sun safety and identify objects that start with the S sound. The amount of nuclear fusion that happens inside the sun is the source of all the energy we get from the sun. pollen. May / June 2019. TM ® & © 2020 Scholastic Inc. All Rights Reserved. We have not yet visited any other planets or gotten close to the sun. No, I don't think Earth is moving away from the sun. The following questions were answered by astronomer Dr. Cathy Imhoff of the Space Telescope Science Institute. The probe is also studying the sun’s atmosphere, the layers of gas around the sun. How did the sun form? Years ago NASA astronauts went to the moon, which is about 250,000 miles away. Always check with your parents before giving out information about yourself, entering a contest or sweepstakes, or buying anything online. 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. Search. We can use the techniques I described above to measure their temperatures. Our moon plays a vital role in sustaining life on Earth. No obligation or credit card is required. Thus the name Proxima. When the sun becomes a red giant, it will be a whole lot hotter in the solar system! Some of the leftover gas and dust going in orbit around this baby sun became the planets. 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. Can you tell me how deep are sunspots? If there is no oxygen in outer space, how does the sun burn? So our sun is kept in its path in our galaxy by the gravity of all those other stars. For comparison, the sun is 93,000,000 miles away — much, much further than the moon. The spacecraft will be equipped with a high-tech heat shield to protect it from the region’s searing 2,500-degree-Fahrenheit temperatures. Tra-la-laaa! 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. Why doesn't the sun drift off into another galaxy? Let's drive 65 miles per hour. Temperatures usually drop as you move away from a heat source. When the magnetic field is at its strongest, it pulls the sun inward. Introduce and reinforce science topics with videos, slideshows, step-by-step tutorials, and other activities. As you watch the video, listen for these important words. They also show us how hot the gases are. Where the sky meets the land is called the __________. This stream of charged particles can disrupt technology on Earth. Brighten up student writing with stationery , clip art, and handwriting practice pages. Pretty big! If the sun became a supernova, the explosion would probably destroy the planets. Then the center of the star will collapse, but only part way. It takes 80 years for the two stars to orbit each other. If you take blue and green away from white, you get orange and red.
