[3] Gordon Williamson explains why. The sun generates a magnetic field of electric currents that radiates throughout the solar system. The sun also has a direct impact on our weather, our bodies and our culture. The second situation that is required is that nuclear fusion must happen. If you don't have a pending eclipse to wow your students with, you can have them create a model of the sun, the earth and the moon and perform their own eclipse. Read on for a range of interesting facts about the Sun. Every sun has a birth, lifespan and a death. A continuous reaction generates energy, some of which we receive as light and other forms of radiation. The Sun keeps our planet warm enough for living things to thrive. When that happens it will expand and grow and eventually engulf Mercury, Venus, and Earth. One star called VY Canis Majoris is around 2,000 times larger than our Sun. The peak of this activity is called a “solar maximum,” and it’s during this time that solar storms occur that include solar flares, sunspots, and coronal mass ejections. The Sun accounts for 99.86% of the mass of our entire Solar System. It's also the center of our solar system and by far its largest object. Once sunlight leaves the sun it travels towards Earth at 300,00 km per second and takes eight minutes to arrive on Earth’s surface. Many civilizations gave credit to the sun for survival, food, and warmth. It also gives out dangerous ultraviolet light which causes sunburn and may cause cancer. The two elements in play are the heavy helium and the lighter hydrogen. The Sun provides us with light and heat. The solar system consists of our sun, which is a star, and all that its gravity affects. When talking about stars, it’s important to remember that the larger the star, the shorter its life will be. The ancient Greeks thought that the sun was a handsome god that they named “Helios.” He was the son of the Titans Hyperion and Theia, and brother to the moon goddess Selene and goddess of the dawn, Eos. It can reach as high a 3.5 million degrees F/2 million degrees C. Scientists don’t know why or what causes the coronal heating condition. The closest star to Earth, it’s the source of all the heat and light that makes flowers bloom, songbirds croon, and sunbathers swoon.Life wouldn’t exist without it. This is where we call “home.” The solar system is made up of some major and minor players, all of which interact with each other. The exception to this is during solar eclipses, when the moon covers the photosphere and the chromosphere appears as a red rim around the sun, and the corona forms a lovely white crown. Enjoy these fun Sun facts for kids. So the sun goes round and round Spreading sunshine on the ground! It is, however, larger than most (although not the biggest) and a very special star to us. The Solar System includes the Sun, the planets which orbit it, the moons which orbit the planets and everything else which orbits the Sun, such as comets and asteroids. There are no moons around the sun nor does the sun have any rings. ©2002 Gareth Lancaster. Explore more poetry like this: Wild World. The sun is held together due to gravitational attraction that produces an intense temperature and pressure at the core. The Sun is a main-sequence G2V star (or Yellow Dwarf). Temperatures in the convective zone reduce to 3.5 million degrees F/2 million degrees C, and this is where large bubbles of soupy ionized atoms called hot plasma begin to move upwards. The Sun is one of the millions of stars in the solar system. The intense gravitational pull of the sun maintains the orbit of things as small as particles all the way to the gas and ice giant planets. When that happens it will expand and grow and eventually engulf Mercury, Venus, and Earth. In its composition, the sun needs to satisfy two critical conditions. These occurrences are due to the irregularities that are within the magnetic field of the sun and they can release intense quantities of particles and energies. When this alteration occurs the corona and the chromosphere change from being calm and somewhat quiet to activity that is violent. This was due to the fact that Helios was considered to be a Titan, part of the highest order of gods, and Apollo was a member of the gods known as the Olympians. At its centre the temperature is 15 million degrees centigrade. At its centre the temperature is 15 million degrees centigrade. The sun does have a kind of thin solar atmosphere. You will know from reading up and learning about the solar system that all planets and other things in … Objective Students will be able to: 1. While a majority of our sun may be gas it does have six distinct regions: the core, the radiative zone, and the convective zone in the interior, the visible surface, called the photosphere; the chromosphere; and the outermost region, the corona. This clip may inspire children to design fact files on the Sun, comparing it to Earth and the Moon. During the solar eclipses we can see the plasma streamers from the crown that narrow outward and create flower-petal-like shapes. The sun is a star, just like the other stars we see at night. A stationary dot? All the planets of the Solar System orbit around the Sun. The sun formed more than 4.5 billion years ago, when a cloud of dust and gas called a nebula collapsed under its own gravity. Resources to Teach Young Students about the Sun. This solar nebula rotated and created a gravity that was so intense that it collapsed. Have you ever wondered why your shadow is longer sometimes and shorter others? The Sun is a yellow dwarf star at the center of our Solar System. As they span out into the solar system they can reach Earth as well as cause damage to satellites, affect our power grids, and corrode pipelines. But it can also burn us. In the sun’s core the hydrogen atoms fuse to create helium. Our sun is made up of ¾ hydrogen and the rest is mostly helium. The design was created to fly seven times closer to the sun than any other spacecraft. A writing frame with a wordbank for children to write facts about the Sun. https://solarsystem.nasa.gov/solar-system/sun/overview/, https://www.sciencefriday.com/articles/science-diction-sun/, https://blogs.nasa.gov/parkersolarprobe/2019/04/05/parker-solar-probe-completes-second-close-approach-to-the-sun/. Pupils could then go on to conduct research projects on our Solar System, the order of the planets from the Sun and their orbits. Sun Facts for Kids. Our sun is made up of ¾ hydrogen and the rest is mostly helium. I have also included some questions to use to study it more closely. ­Officially, the sun is classified as a G2 type star, based on its temperature and the wavelengths or spectrum of light that it emits. Our sun will continue to shine for around 130 million more years and then it will stop burning its hydrogen and begin to burn helium. The Sun is composed of hydrogen (70%) and Helium (28%). The Sun is fundamental to our life on Earth. Scientists have indicated that our sun has gone through around half of its lifecycle and will continue to shine for an additional 6.5 billion years before it eventually shrinks and becomes a white dwarf star. How you can tell the time of day from shadows cast by the Sun. The difference is distance -- the other stars we see are light-years away, while our sun is only about 8 light minutes away -- many thousands of times closer. videos. It continued to spin fast and faster and then flattened into a disk-shape. The Sun is a star and gives out heat and light. The surface of the sun is the photosphere, and it’s around 300 mi/500 km thick. The lesson is on how the tilt of the Earth, when it's orbiting the sun, gives us our seasons. The Sun is located in the center of the Solar System. The Sun is fundamental to our life on Earth. This clip may also lead to rich discussion about our Solar System and how it was created, thinking about scientific evidence and theories. Around every 11 years the magnetic polarity of the sun’s geographical poles change. This KS2 Science quiz is all about our solar system. Without the Sun there would be no daylight, and our planet would simply be a dark, frozen world, with no oceans of liquid water and no life. This very simple sun poem is great for teaching personification to children. A lesson for year 5 on their topic for this term: Earth and Space. It is a nearly perfect sphere of hot plasma, essentially, a hot ball of glowing gases. Neither. Read about our approach to external linking. The sun’s mass is around 70.6% hydrogen and 27.4% helium. May also be useful for EYFS or Y1. This is called the “solar wind” and it’s a stream of gas that is electrically charges that blows out in all of the directions of the sun. The Sun is our main source of light. The Sun is 870,000 miles (1.4 million kilometers) across. Scientists have long held discussions on the exact size needed but it’s believed that it needs to be around 80 times the mass of our planet Jupiter. An introduction to the Sun and its role in our galaxy. Energy that is being created in the sun takes millions of years to travel from the core inside and make its way to the surface of the sun. However, it is due to the energy from the sun that life on Earth is possible. A majority of the material was pulled into the center to form the sun and its mass accounts for 99.8% of the mass of our entire solar system. The process of nuclear fusion is when two lighter atomic nuclei fuse together to create an atomic nucleus that is heavier. It has temperatures and pressures that are incredibly hot and has and plasma mixtures that don’t offer even the basic options for anything to live. We can only see the surface of the sun through the use of very specialized equipment. Energy at the core is then carried out by radiation and that bounces around for about 170,000 years in the radiative zone until it gets to the top of the convective zone. The largest undertaking for exploration of the sun is the NASA Parker Solar Probe. Mercury, named after a Roman god, is 36 million miles away from the sun and 48 million miles from Earth. Want more? Earth rotates on an axis. The tops of these areas have visible light that is normally too weak to be viewed against the intensely bright photosphere. Rating: Share This Poem. Our sun has a diameter of 864,340 mi/1.39 million km, and that’s 110 times the diameter of the Earth. As he traveled he would deliver sunshine throughout the world and then repeat his rounds every morning after Eos created the new dawn. The solar system [3] At its core, the sun’s temperature is about 15 million degrees Celsius (about 27 million degrees Fahrenheit). That's everything which orbits the Sun, including the planets - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. That means that there could be over 1 trillion stars that are similar to our sun in the universe. The sun's heat also creates a vast amount of energy on our planet, in fact, pretty much all energy created and used on Earth derives from the sun in one way or another. When we look at the sky we think that our sun is incredibly large, however, when scientists compare our sun to other stars it’s just a bit larger than average. Looking at the sun you wouldn’t think that it’s moving but it’s actually traveling through space at 220 km per second. However, in doing so, they replaced the Greek word for sun, Helios, with the Latin root work of “Sol.” One of the most powerful Roman sun gods was Sol Invictus, which translates to “Unconquered Sun.”. The surface is around 10,000 degrees F/5,500 degrees C and although it’s a lot cooler that the intensely hot core, it’s still hot enough to make elements such as diamonds, carbon, and graphite boil. Our sun’s surface is between 5,027-5,727 degrees C. In examining our Milky Way galaxy, scientists think that there are nearing seven billion stars that are similar to our sun. http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewPodcast?id=283424434 We look at the sun rising every day. Many people are aware of harnessing solar energy to create power, but the Sun is also the main cause of the weather patterns and air currents we experience on our planet. Since the sun rotates, the stream of particles blows out in a spiral that is called the “Parker Spiral.” When these electrical particles slam into planets and other celestial objects it can cause damage unless stopped or veered off by atmosphere, magnetic fields, or both. An introductory PowerPoint about the sun I originally made for my Y2 SEN class. What would the sun look like in that combined image? Explain the locations of the Earth, moon and sun and describe their relationship 2. The magnetic field of the sun is incredibly powerful and can create magnetic storms and solar flares that interfere with our satellites and electronic equipment on Earth. It will eventually run out of energy and begin to die.eval(ez_write_tag([[580,400],'planetsforkids_org-box-4','ezslot_6',187,'0','0'])); When that happens it will enlarge to a size that is so big that it will engulf Mercury, Venue, and probably Earth as well. The sun has temperatures inside that can reach 15 million degrees C. It takes around 8 minutes from the moment that it leaves the sun to reach our planet. Recent Comments. While we might think of our sun as absolutely huge, it is an average size when compared to other stars. Many children automatically relate to the sun as a smiling face, so this poem introduces personification to them using this idea. The first one is that it has to occupy the generally accepted range of its mass which is 1.4 x … Our solar system is in the Milky Way galaxy and located in an outer spiral arm. The sun also contains negligible amounts of oxygen, silicon, neon, carbon, magnesium, nitrogen, sulfur, and iron gases. It is the smallest planet in the solar system, with a diameter of 3,031 miles. She looks upon the earth below With smiling eyes and cheeks that glow, The sun is a G2 Yellow dwarf star and is around 4.6 billion years old. Unlike rocky planets, there isn’t any kind of solid surface of the sun because its outer layer is gas. KS2 The mass of our sun makes up 99.86% of the total mass of the entire solar system. A unit plan on space and the earth, moon and sun. Find out more in this Bitesize Primary KS2 Science guide. Email Poem to a Friend Tweet About It Post it on Facebook Print it Out. During the second perihelion the spacecraft sent back data indicating that the craft was operating well and collecting scientific information. The sun is the closest star to Earth and is 149.60 million kilometers (92.96 million miles) away. The Sun’s surface area is 11,990 times that of the Earth’s. Scientists have developed a list of classifications for stars and our sun is listed as a class GV, also known as a Yellow Dwarf star. The sun started to form and take shape at the time the solar system was also forming. Most of the sun is made up of helium and hydrogen. We have carried the name “sol” forward to today as it represents anything related to our sun, including our solar system. During the winter, the North Pole is tilted away from the Sun's rays. So it’s a good thing that our sun is the right size to have a longer life. The Sun is all the colours mixed together, this appears white to our eyes. There are changes between the distance of the Earth and sun but we don’t really notice them due to the elliptical orbit path of the Earth. NGSS Standard: MS-ESS1.A-1 ​ Patterns of the apparent motion of the sun, the moon, and stars in the sky can be observed, described, predicted, and explained with models. Jupiter is a gas giant made up of the same gasses as our sun. The ancient Romans took much of their culture from the Greek and as their empires progressed they worshipped a number of sun gods. As Earth travels around the Sun, the tilt of Earth changes. The classification of a star isn’t based on size but instead it relates to the surface temperature. This is the area above the photosphere where we find the tenuous chromosphere and the crown or “corona.” Through the use of specialized equipment we can view this area to see solar flares and sunspots. Our sun gives us warmth and energy that other organisms such as plants can use to create their food. Once our sun begins to expand it will eventually become a red giant star. Here are some fantastic facts about the Sun that you can teach your KS2 students:It takes 8 minutes for light from the Sun to reach the Earth.Directly looking into the Sun for too long can damage your eyesight.The Sun is around 4.5 billion years old.The surface temperature of the Sun is around 5500 degrees Celsius.It is around 865,000 miles wide. Our sun is the “star” of our solar system and as such, some worshipped it as a god. This is the place where most of the radiation from the sun escapes outward. The Sun’s diameter is around 109 times the size of Earth’s, and you could fit the Earth inside the Sun about 1,300,000 times. The biggest stars in the universe are the red giants and the smallest ones are red dwarfs. Mass: 333 thousand times the mass of Earth Diameter: 109 times the diameter of Earth Temperature: 5,500 degrees C (10,000 degrees F) on the surface Distance from Earth: 150 million kilometers (93 million miles) Age: 4.5 billion years What is the Sun like? Gravity is what gives celestial bodies their circular shape and with such powerful gravity, our sun is the closest thing in nature to being a perfect sphere. Includes 3 videos with a couple of tasks for the children to do and one main activity. An introduction to the Sun and its role in our galaxy. Differentiated for less able with words to fit into sentences and more able … Our sun is made up of two main gases: hydrogen and helium and is referred to as a “sequence star.”. Despite this, the Sun is still only a medium-sized star. Helios’ crown was said to be a sunbeam burst, and each day he would drive his chariot of the sun across the sky that was drawn by fire-breathing-horses. It takes 87.96 Earth days for Mercury to revolve around the sun, faster than … As we continue to explore the galaxies we are finding that our sun is just one of many trillions of stars that are in the universe. Suppose you placed a camera at a fixed position, took a picture of the sky at the same time every day for an entire year, and overlaid all of the photos on top of each other. Had Jupiter grown to equal the mass of our sun nuclear fusion would have happened and we would have had two suns or stars in our solar system. I have also used this powerpoint when teaching Unit 44 Astronomy on the BTEC Level 3 in Applied Science. The sun is not conducive to allowing life as we know it to exist, adapt, and thrive. Subscribe to NASA on iTunes! We could put 1 million Earths inside the sun. As time passed the name of Helios began to be associated with the god of light, Apollo, however, most Greeks maintained them as separate gods. The Sun is 109 times wider than the Earth and 330,000 times as massive. Nuclear reactions at the core of the Sun create energy in the form of heat and light. Our solar system began around 4.5 billion years ago as a huge cloud of gas and dust called a solar nebula. Copyright 2019 Planet For Kids. eval(ez_write_tag([[580,400],'planetsforkids_org-medrectangle-3','ezslot_5',601,'0','0'])); There are also dwarf planets such as Pluto, dozens of moons and millions of asteroids, comets and meteoroids of all shapes and sizes.eval(ez_write_tag([[336,280],'planetsforkids_org-medrectangle-4','ezslot_8',198,'0','0'])); Our sun is a hot ball of gases that is the very center of our solar system. A powerpoint that follows the first 4 lessons of Edexcel Astronomy GCSE covering: the structure of the Sun; sunspots; solar cycles; and, the solar spectrum. The core’s temperature is about 27 million degrees F/15 million degrees C. This is hot enough to continue the constant state of thermonuclear fusion, a process where atoms combine to create larger atoms and in that process they release huge amounts of energy. The sun isn’t a static or non-changing star, as it goes through its own phases of the solar cycle. An explanation of how the Sun is the main source of energy for all life on earth. [3] The sun rotates on its axis once every 25.38 Earth days or 609.12 hours. Without the Sun there would be absolutely no life on Earth. Learn how hot the Sun is, how long it takes light from the Sun to reach Earth, what the Sun is made of and more. All Oddly, the temperature of the sun’s atmosphere increases with altitude. It takes our sun 225-250 million years to complete an orbit around the Milky Way galaxy. Our sun will continue to shine for around 130 million more years and then it will stop burning its hydrogen and begin to burn helium. Oddly enough, it makes a ‘figure 8’ pattern, known as the Sun’s analemma. The Sun is a star found at the center of the Solar System. The creating of our sun happened with two extremely specific situations, the first was that the sun’s mass had to be big enough to be able to allow nuclear fusion to occur. All rights reserved. It gives us light so we can see. Our sun has been the center of attention for humankind throughout the ages. Like other stars, our sun is basically a large ball of gas that is 91% hydrogen and 8.9% helium. The Sun is our nearest star. It is a huge ball of very hot gas. Our sun’s rotation is opposite of the rotation of the Earth. We started by singing 'The sun has got his hat on' then did different activities through the Powerpoint like taking it in turns to be the sun and the earth moving around it, and trying on different sunglasses and hats. The Sun is part of a system of hundreds of billions of stars - a galaxy - called the Milky Way. The gravity of the sun is what keeps all of the planets, moons, and bodies within our system together. I have merged the Hamilton planning (available from Hamilton Trust) with Primaryupd8 lessons which fit well (and added a little bit of creativity). Every sun has a birth, lifespan and a death. The sun is the real star of the show—literally! The radiation from the photosphere appears as sunlight as it reaches Earth. A circular path? In this video you will be taken on a spectacular adventure to the Earth, Sun and Moon. It is a huge ball of very hot gas. Explain the movements of the Earth, moon and sun by developing models Time Required:​ 90 minutes In 2019 it successfully completed a second close approach to the sun, called the “perihelion,” passing within 15 million miles and traveling at 213,200 mph. Enclosed are worksheets to accompany the first 3 lessons. The planets in our solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Once our sun enters the red giant stage it will eventually collapse until it nears the size of our Earth and at that time it will be a white dwarf star. eval(ez_write_tag([[300,250],'planetsforkids_org-medrectangle-1','ezslot_11',176,'0','0']));report this ad. eval(ez_write_tag([[728,90],'planetsforkids_org-large-leaderboard-2','ezslot_10',192,'0','0'])); It’s the energy that is created at the core that acts as the engine that powers the sun and makes all of the light and heat that is emitted from the sun. Examples given include how the sun makes cars able to function and why crisps are a product of the sun. The interaction between the sun and the Earth is what gives us our weather, climate, ocean currents, seasons, radiation belts, and aurorae.
