The Earth and Other Planets Standards: 6.8 The student will investigate and understand the organization of the solar system and the relationships among the various bodies that comprise it. Key concepts include a) the sun, moon, Earth, other planets and their moons; b) relative size of and distance between planets; Resources: Celestia, Virginia SOL Enhanced Scopes and Sequence Lesson Plan Outline: Topic Introduction to the planets of the Solar System – relative size and distance from the sun. Instructional Objective(s) Students will be able to: - describe the relative sizes of the planets compared to each other - differentiate between planets based on their unique distances from the sun Materials & Resources Celestia, smart board, worksheets, scopes and sequence Engage Cut out circles of all planets (with no names or labels) that are the correct proportions in size and have students put them in order from largest to smallest. Then the students guess which planets are which based on their sizes and share their answers with the class. Explore First, students will be given a poster and small materials such as a quarter, grain of salt, pencil eraser, etc. As a group, students will predict which planet each object is similar to in size. Each group will share their predictions with the class. Then the class will have an introduction to Celestia – go around to each planet and observe unique features and characteristics, specifically distance from sun and size. Students then organize their planets from largest to smallest while learning each planet size, correcting their predictions where necessary. In their groups, they will make a poster with all of the objects, labeling each one as its respective planet and including a brief explanation. Explain Students will look at the acronym for the order of the planets from the sun –M.V.E.M.J.S.U.N.P. – and make up their own acronym to describe the order of the size of the planets from largest to smallest. Extend Worksheet of relative sizes (attached) Evaluate Formative assessment throughout the lesson, observing the students and their participation, listening to their explanation of their posters. Plans for Diversity Student(s): ELL’s Category/Characteristics: Cannot speak English very well or at all Accommodations: using a lot of pictures and labeling to connect vocabulary with definitions. Student: Lower Level Learners Accommodations: extra help and attention for them, group work so they can learn from their peers, lots of pictures. Connections Students need to know the relative distances and sizes of each planet in order for them to understand other phenomenon later in the unit that happens because of those sizes and distances – like gravitational pull, moons, etc. Reflections There really is no lecturing in this unit. The only time I’m talking is to give instructions, lead discussions, or during the exploration of Celestia, which is more showing the students the solar system and narrating everything. Worksheet Day 1 Find out whether there is a pattern to the sizes (diameters) of the planets: 1. Is Venus bigger than Mercury? ________ 2. Is Earth bigger than Venus? ________ 3. Is Mars bigger than Earth? ________ 4. Is Jupiter bigger than Mars? ________ 5. Is Saturn bigger than Jupiter? ________ 6. Is Uranus bigger than Saturn? ________ 7. Is Neptune bigger than Uranus? ________ 8. Is the dwarf planet Pluto bigger than Neptune? ________ 9. Do the planets get bigger as they get farther away from the sun? ________ Make your observations about solar system distances: 10. Which two planet markers are closest together? ________________________ 11. Which two adjacent planet markers are farthest apart? _____________________ 12. Is the distance between Earth and Venus greater than the distance between Venus and Mercury? ________ 13. Is the distance between Mars and Earth greater than the distance between Earth and Venus? ________ 14. Is the distance between Jupiter and Mars greater than the distance between Mars and Earth? ________ 15. Is the distance between Saturn and Jupiter greater than the distance between Jupiter and Mars? ________ 16. Is the distance between Uranus and Saturn greater than the distance between Saturn and Jupiter? ________ 17. Is the distance between Neptune and Uranus greater than the distance between Uranus and Saturn? ________
