    • Ana PerezVanessa GarciaCindy AlvarezEva Jacinto Solar System Lesson PlanGrade: K-12 appropriateContent Area: Science and GeographySubject: The Solar SystemContent Standards Earth Sciences The solar system consists of planets and other bodies that orbit the Sun in predictable paths. As a basis for understanding this concept: o Students know the Sun, an average star, is the central and largest body in the solar system and is composed primarily of hydrogen and helium. o b. Students know the solar system includes the planet Earth, the Moon, the Sun, eight other planets and their satellites, and smaller objects, such as asteroids and comets.Content Objectives To help students obtain a clear understanding of the size of the sun and the other planets in our solar system. Help students grasp the concept of the vastness of our universe.Student Objectives Engaging students to be excited and in awe of the huge world we live in! Teaching basic concepts of measurement and distance (inches, yards, miles) Strengthening knowledge of planets in the solar system Increasing understanding of size of the sun and other planets Learning the scale of the solar system Encouraging children to explore the universe on their own.Materials Sun – Inflatable Ball / bowling ball size Mercury -a pinhead Venus - a peppercorn Earth- a second peppercorn Mars -a second pinhead
    • Jupiter – a chestnut or a pecan Saturn – a hazelnut or an acorn Uranus – a peanut or coffee bean Neptune a second peanut or coffee bean Pluto - a third pinhead/ or smaller item Pieces of paper or cards to pin/place planets on Label each piece of paper with the name of the planets The pinheads will need to be pinned to labeled cards or paper to make them visible. Find space near the school where you can walk one thousand yards.Questions Does anyone know what makes up our solar system? Who can tell me what is the biggest planet? Does anyone know how far it is from the Sun to the Earth? Who knows something really interesting about the solar system that you want to share with the class? o Teacher Information to share o From the Sun to the Earth is about 93,000,000 (93 million) miles. o The average distance from the Sun to Pluto is much larger, about 40 times the distance from the Sun to the Earth. o The Sun to the Plutoid Pluto distance is typically referred to as 3.7 BILLION.  To give you a sense for how far this is, imagine you are driving to Pluto on the highway at the speed of 60 miles per hour; it is going take you about 7 thousand years to reach your destination!Instruction Put the objects out on a table and place them in a row. Explain to the class that these objects will be used to create your class model of the solar system. o Remind class about previous lessons in which we learned about the size of the planets and their order. Remind the class about the mnemonics we have learned. Before you leave, distribute the Sun, the planets, and the labeled paper to members of the class. Make sure that each student knows the name of the object he or she is carrying. As this model calls for participation from eleven students, you’ll want to pair up students and assign a planet to more than one child. Take 10 paces. Call out “Mercury, where are you?” and have the Mercury person put down his/her card and pinhead. Take another 9 paces. Ask Venus to put down her peppercorn. At this point you may want to take out the megaphone so everyone can hear you. This is not essential but it may place less strain on your vocal chords. Take another 7 paces. It’s Earth’s turn. o Ask the class if they notice anything amazing so far? Point out that Mercury is so close to the sun but we never see it. It is like a scorched rock and it is lost in space. And as for the distance between Earth and the Sun, can you believe that it warms us so well and we are so far from it?
    • Take another 14 paces. Mars. Take 95 paces from there to Jupiter. o As you or the Pace Explorer is taking paces, continually ask the class questions such as “Who knows an interesting fact about Jupiter?” What is so amazing about this? Point out that Jupiter is so large that you could fit all the other planets inside it. And in our model it is just a chestnut, more than a city block from its nearest neighbor in space! Another 112 paces. Saturn Another 249 paces. Uranus Another 281 paces. Neptune Another 242 paces. Plutoid, Pluto “What observations they have about the model? o Point out that the sun ball is no longer visible even with binoculars from the pinhead Pluto. The inconceivable size and wonder of space may now start to set in.Extension of Activity Moon An early target for spacecraft and astronauts. It is very unearthlike - no air, no water, no active volcanoes. As such it preserves its ancient geological record much better than Earth. Sun The central mass which holds the Solar System together and provides us with warmth and light. The sun, a fairly average star, produces power by converting hydrogen to helium. It will do so for several billion years more, gradually becoming warmer. Earth Earth is the only planet known to support life. Mars Planet Mars is the 4th planet from the Sun, and is named after the Roman god of war; perhaps for its red coloring. It is intermediate in geological development between Earth and the Moon. It has had water on its surface in the past, though now all water is frozen. Venus Venus was named after the Roman goddess of love and beauty, but is now known to be very different from Earth. It has no oceans and is surrounded by a heavy atmosphere Mercury Mercury was named by the Romans after the fleet-footed messenger of the gods because it seemed to move more quickly than any other planet Jupiter the largest planet in the Solar System.[9][10] It is the fifth planet from the Sun. Jupiter is classified as a gas giant, because it is so large, and is made up mostly of gas. Saturn The sixth planet from the Sun and the second largest planet in the Solar System,Evaluation By observing that each person is interacting in the solar system you are able to observe that each child is engaging. By having each child answer questions about the planet they represent the class is able to learn and their comprehension is evaluated.
    • Follow- Up Activity Ask student pairs to write up fun facts on their planet cards about the planet they represent. Have them share their facts and see who can guess which planet they are. Do the walk once more from the Sun to Pluto and then immediately in reverse, starting with Pluto. This will help reinforce the concept of the scale of the solar system through repetition.Description of lesson plan: Student will learn how to locate the planets in order. They will alsoget an idea of how far apart they are from each other. Another thing will be students will get anidea of a relevant size of each planet. Students will understand why Pluto is not a planet anymore.Description of how geography is used in the lesson plan:Geography is included in this lesson plan because students will learn about The Solar System -the sun and all things bound to it - is our neighborhood in space. Previously the object of onlyastronomical study, it is now accessible to human endeavors, at least in its nearest parts. This is aGeography course, and it would be thought of it in geographical terms: places, resources,hazards, etc. The Solar System would be briefly discussed in astronomical terms. Students willalso get an idea of how each planet got is name. Mnemonic Refresher My = Mercury Very = Venus

If you weigh 100 lbs, your weight on Neptune would be 113 lbs. (multiply your actual weightby 1.18) Reasons Pluto isn’t a Planet The requirements are: It needs to be in orbit around the sun--Yes, Pluto does orbit the sun It needs to have enough gravity to pull itself into a spherical shape -- Pluto has sufficient gravity to have become spherical. (This is called hydrostatic equilibrium, by the way.) It needs to have "cleared the neighborhood" of its orbit -- Uh oh. Heres the "problem" with Pluto. According to this IAU rule, Pluto is not a planet.
    • We see the "rule violation" that has arisen, but what does "cleared its neighborhood" mean? Asplanets form, they become the dominant gravitational body in their orbit in the Solar System. As they interact with other, smaller objects along their orbital path, they either consume them or sling them away with their gravity. Pluto is only 0.07 times the mass of the other objects in its orbit. The Earth, in comparison, has 1.7 million times the mass of the other objects in its orbit.Any object that doesnt meet these 3rd criteria is considered a dwarf planet. And that makes Plutois a dwarf planet. There are still many objects with similar size and mass to Pluto jostling around in its orbit. And until Pluto crashes into many of them and gains mass, it will remain a dwarf planet. Eris suffers from the same problem.Its not impossible to imagine a future, though, where astronomers discover a large enough object in the distant Solar System that could qualify for planet-hood status. Then our Solar System would have 9 planets again. Even though Pluto is a dwarf planet, and no longer officially a planet, itll still be a fascinating target for study. And thats why NASA has sent their New Horizons spacecraft off to visit it. New Horizons will reach Pluto in July 2015, and it will capture the first close-up images of the (dwarf) planets surface.Space enthusiasts will marvel at the beauty and remoteness of Pluto, and the painful deplanetingmemories will fade. Well just be able to appreciate it as Pluto, and not worry how to categorize it. At least now you know why Pluto was demoted.Pluto is not considered a planet because it shares its orbit with many other objects, so it fails one of the criteria for a planet established in 2006: 1. The object must orbit a star such as the sun 2. Must be rounded by its own gravity and be in hydrostatic equilibrium 3. Must have cleared its orbital path of other objects
