  1. OUR SOLAR SYSTEM Grade 6 By Lauren Rickman

  2. TENNESSEE SCIENCE STANDARDS • Grade Level Expectations GLE 0607.6.1 Analyze information about the major components of the universe. GLE 0607.6.2 Describe the relative distance of objects in the solar system from earth.

  3. State Performance Indicators • SPI 0607.6.1 Use data to draw conclusions about the major components of the universe. • SPI 0607.6.2 Explain how the relative distance of objects from the earth affects how they appear.

  4. Checks for Understanding • 90607.6.1 Use data to draw conclusions about the major components of the universe. • 90607.6.2 Construct a model of the solar system showing accurate positional relationships and relative distances.

  5. Guiding Questions • Conceptual Strand 6 The cosmos is vast and explored well enough to know its basic structure and operational principles. • Guiding Question 6 What big ideas guide human understanding about the origin and structure of the universe, Earth’s place in the cosmos, and observable

  6. Plan for this Lesson • Begin by asking students open ended questions about the solar system to find out what the know • Work with the students on their conceptions and misconceptions about our solar system • Learn about and research the Milky Way and the planets • Two projects: one class project and one group project

  7. What is the solar system? • The solar system is the system of planets and other objects orbiting the star Sol, which happens to be our Sun. • Our solar system is located in the Milky Way galaxy. The word ‘galaxy’ is Greek for Milky Way.

  8. Common Misconceptions about the Solar System • The Earth is larger than the sun • The Earth is the center of the Solar System. • The solar system is extremely crowded • Planets are close together • The sun goes around the earth • The sun is on fire or burning • The planets are basically the same size • Time passes the same on each planet http://www.scienceboom.com/wp-content/uploads/pages/101_misconceptions.pdf http://scc.losrios.edu/~sah/physics/44Miscon.htm

  9. What makes a planet a planet? • The IAU, International Astronomical Union, defines a planet as: A celestial body that orbits the sun, has sufficient mass for its gravity to overcome rigid forces so that it assumes a nearly round shape, and has cleared the neighborhood around its orbit. http://www2.ess.ucla.edu/~jlm/epo/planet/planet.html

  10. Vocabulary • Planet comes from the Greek word for wanderer • Solar System • Milky Way • Galaxy • Revolution • Rotation • Astronomical Unit

  11. Can you name all the Planets? • Mercury • Venus • Earth • Mars • Jupiter • Saturn • Uranus • Neptune

  12. Remembering all the Planets Remembering all of the planets can be difficult. There are some special things you can do to help remember them. You can use a mnemonic device such as My Very Eager Mother Just Served Us Nachos You can even use songs such as the Animanics Planet song to remember The Planet Song

  13. The Sun • The sun is the center of the Milky Way • It makes up 99.86% of our solar system’s mass • It is 74% hydrogen, 24% helium and the rest is made up of oxygen, carbon, iron, and neon • 1,000,000,000 Earths can fit in the sun – it is enormous! • The sun’s surface is 9941 degrees F • Light from the sun reaches the earth in about 8 minutes • The planets revolve around the sun http://www.sciencekids.co.nz/sciencefacts/space/sun.html

  14. Mercury • Mercury is the planet closest to the sun • Mercury is the second smallest planet in the solar system • It is bigger than Earth’s moon • Surface: rocks, craters, and dust • Temperatures range from 800 degrees to – 279 degrees. • No atmosphere to retain heat so it can get super cold • 1 mercury day = 58.6 Earth days http://science.nationalgeographic.com/science/space/solar-system/mercury-article/

  15. Venus • The hottest planet in our solar system! • Temperature on surface is approx. 932 degrees • Made up of mainly Carbon Dioxide • Almost same size as earth • Cannot support human life • No water is found on this planet • 1 day in Venus = 1 Earth year http://www.sciencekids.co.nz/sciencefacts/planets/venus.html

  16. Earth • Third rock from the sun • 30% of earth is covered in land, 70% in water • The atmosphere and environment are ideal for sustaining human life • Earth has only one moon • The Earth isn't perfectly round, it is slightly flattened at the north and south poles.  • Scientists have the dated the Earth as being between 4 and 5 billion years old http://www.sciencekids.co.nz/sciencefacts/earth.html

  17. Mars • Nicknamed the Red Planet because it is covered with rust-like dust • Has a very weak gravity • Little atmosphere to hold in heat so planet is very cold. Temps range from 77 degrees in the summer to -184 degrees in the winter • Mars experiences different seasons like Earth • Largest space volcano, Olympus Mono, is located here http://www.sciencekids.co.nz/sciencefacts/planets/mars.html

  18. Jupiter • The largest planet in our solar system • 1,300 Earth can fit inside Jupiter • It is made up 100% of gas • Has a very strong gravity, you would weigh 2 ½ times more on Jupiter • Has very thin rings • Jupiter has many moons http://www.sciencekids.co.nz/sciencefacts/planets/jupiter.html

  19. Saturn • 2nd largest planet • Has small rocky core covered with liquid gas • Saturn is twice as far from the sun as Jupiter • It has many rings that are made of ice crystals, some as big as houses • Has a high magnetic field which traps energy particles resulting in high levels of radiation • Has many moons, like Jupiter http://www.sciencekids.co.nz/sciencefacts/planets/saturn.html

  20. Uranus • Has a blue/green haze due to high levels of methane gas • Methane absorbs red light and scatters blue light • This planet rotates on its side, it rolls like a barrel • scientists guess that under the hydrogen-methane atmosphere is a hot, slushy ocean of water, ammonia and methane thousands of miles deep wrapped around a rocky core. http://www.sciencekids.co.nz/sciencefacts/planets/uranus.html

  21. Neptune • Boasts the most violent weather in the solar system • Storms with freezing winds that blow about ten times faster than hurricanes on Earth • Four times the size of Earth • a large, water planet with a blue hydrogen-methane atmosphere and faint rings. http://www.sciencekids.co.nz/sciencefacts/planets/neptune.html

  22. Pluto: Dwarf Planet In 2006 Pluto was demoted to the status of dwarf planet. Pluto consists of rock with a very thick coating of ice. The atmosphere consists of nitrogen with some carbon monoxide and methane. Because it is so far away from the sun it is very cold. Temps range form -391 Degrees Celsius to -346 Degrees Celsius. http://www.sciencekids.co.nz/sciencefacts/planets/pluto.html

  23. The Sun goes around the Earth(Misconception #1) • The sun is the center of our solar system • All of the planets in our solar system revolve around the Sun • When something is moving in a circle around another object, such as the way the Moon Circles the Earth, it is said to revolve around that object.

  24. Time Passes the Same on Each Planet(Misconception #2) • Earth has a 24 hour day. This is determined by how long it takes the Earth to rotate on its axis. • When an object spins it is said to be rotating. • Each planet spins at a different rate, therefore the number of hours in 1 day varies.

  25. The Planets are close together(Misconception #3) • Our solar system is vast and the planets are far away one another • This can be measured in miles (distance) or time. • An astronomical unit is a measure of 1 Earth year. • The AU is determined by how long it takes each planet to revolve around the Sun. • Example: Mercury rotates around the sun 0.39 AU which is roughly 87.96 Earth days.

HELPFUL RESOURCES Brain Pop http://www.brainpop.com/science/space/ NASA http://spaceplace.nasa.gov/menu/solar-system/ Documentaries: http://www.youtube.com/watch?v=cDXrdQbsikA Solar System Songs: The Planets http://www.youtube.com/watch?v=s8eFFnJsCjs&feature=related Solar System Song http://www.youtube.com/watch?v=GH61v4_eVNA Interplanet Janet http://www.youtube.com/watch?v=vmYVWJ82dQQ

  27. Class Project • Create a replica of the solar system • Each group assigned a planet will make that planet out of whatever material they chose (as long as it isn’t perishable) • We will work collectively as a class to convert the millions of miles from the sun to inches or cm from the sun so it will fit in the classroom.

  28. Planetary News 9 • The students will be separated into groups of 3-4 and assigned a planet. They will be allowed lab time to research their planets via library or internet searches. Plenty of class time will be devoted to group discussions. After their research, the students will make their own ‘local’ news program about their planet. The students should include a weather report, on the scene, breaking news, time, etc. • Planets will be chosen via a random drawing • The news can either be filmed or presented orally in class

  29. Connection to Math • Converting Miles to Inches: 5,280 ft/1 mile x 12 inches/ 1 ft Converting Miles to Centimeters: 5,280 ft/1 mile x 12 inches/ 1ft x 2.54 cm/1 inch *This would be A LOT of inches so we will say that 36 million miles = 36 miles. For example, Mercury would be 2,280,960 inches, but we will say 1 million = 1 inch. *
