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. 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. 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. 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 also contains negligible amounts of oxygen, silicon, neon, carbon, magnesium, nitrogen, sulfur, and iron gases. We have carried the name “sol” forward to today as it represents anything related to our sun, including our solar system. It's also the center of our solar system and by far its largest object. Find out more in this Bitesize Primary KS2 Science guide. http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewPodcast?id=283424434 We look at the sun rising every day. Neither. The sun isn’t a static or non-changing star, as it goes through its own phases of the solar cycle. 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. The sun started to form and take shape at the time the solar system was also forming. The sun generates a magnetic field of electric currents that radiates throughout the solar system. The lesson is on how the tilt of the Earth, when it's orbiting the sun, gives us our seasons. The Sun is a star and gives out heat and light. It takes 87.96 Earth days for Mercury to revolve around the sun, faster than … 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. Pupils could then go on to conduct research projects on our Solar System, the order of the planets from the Sun and their orbits. Every sun has a birth, lifespan and a death. Our sun is made up of two main gases: hydrogen and helium and is referred to as a “sequence star.”. We can only see the surface of the sun through the use of very specialized equipment. This clip may inspire children to design fact files on the Sun, comparing it to Earth and the Moon. 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. The sun is the closest star to Earth and is 149.60 million kilometers (92.96 million miles) away. Our sun gives us warmth and energy that other organisms such as plants can use to create their food. The Sun is 870,000 miles (1.4 million kilometers) across. The sun is held together due to gravitational attraction that produces an intense temperature and pressure at the core. The Sun is our nearest star. It is, however, larger than most (although not the biggest) and a very special star to us. Have you ever wondered why your shadow is longer sometimes and shorter others? The biggest stars in the universe are the red giants and the smallest ones are red dwarfs. When that happens it will expand and grow and eventually engulf Mercury, Venus, and Earth. It is the smallest planet in the solar system, with a diameter of 3,031 miles. 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. The Sun is all the colours mixed together, this appears white to our eyes. A lesson for year 5 on their topic for this term: Earth and Space. It takes around 8 minutes from the moment that it leaves the sun to reach our planet. 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. eval(ez_write_tag([[300,250],'planetsforkids_org-medrectangle-1','ezslot_11',176,'0','0']));report this ad. Earth rotates on an axis. Once our sun begins to expand it will eventually become a red giant star. The Sun is our main source of light. Despite this, the Sun is still only a medium-sized star. Explain the locations of the Earth, moon and sun and describe their relationship 2. This is the place where most of the radiation from the sun escapes outward. 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? The Sun is fundamental to our life on Earth. 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. It also gives out dangerous ultraviolet light which causes sunburn and may cause cancer. 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 solar system Copyright 2019 Planet For Kids. 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 interaction between the sun and the Earth is what gives us our weather, climate, ocean currents, seasons, radiation belts, and aurorae. During the winter, the North Pole is tilted away from the Sun's rays. 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. A stationary dot? 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. So it’s a good thing that our sun is the right size to have a longer life. The sun has temperatures inside that can reach 15 million degrees C. 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. The sun does have a kind of thin solar atmosphere. [3] The sun rotates on its axis once every 25.38 Earth days or 609.12 hours. 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. Our sun has a diameter of 864,340 mi/1.39 million km, and that’s 110 times the diameter 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. The mass of our sun makes up 99.86% of the total mass of the entire solar system. It gives us light so we can see. 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. The sun is the real star of the show—literally! One star called VY Canis Majoris is around 2,000 times larger than our Sun. The solar system consists of our sun, which is a star, and all that its gravity affects. 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. I have merged the Hamilton planning (available from Hamilton Trust) with Primaryupd8 lessons which fit well (and added a little bit of creativity). 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. Our sun’s rotation is opposite of the rotation of the Earth. While we might think of our sun as absolutely huge, it is an average size when compared to other stars. Subscribe to NASA on iTunes! Read about our approach to external linking. Gordon Williamson explains why. The radiation from the photosphere appears as sunlight as it reaches Earth. Nuclear reactions at the core of the Sun create energy in the form of heat and light. 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. 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.
