Layers of the Earth

thingiverse

Students used the Revolved 101 app on the iPads to create a model of the layers of the Earth by using lines of symmetry. Students need to be able to identify the four layers of the Earth: Crust, Mantle, Outer Core, and Inner Core as well as understanding their proportions to each other. Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator (5th Generation) Notes: The Revolved 101 app is a free app from the Apple app store. We used iPad minis to complete this project. The teacher was then able to upload the .STL files directly from the app to their Google Drive, email, Dropbox, or notes account in order to get it printed on the printer. How I Designed This Revolved 101 Students used the Revolved 101 app and worked with lines of symmetry to complete their models. https://itunes.apple.com/us/app/revolved-101/id1033626530?mt=8 Standards CCSS Overview and Background Students learn about the different layers of the Earth. They need to understand that in the early part of the 20th century, geologists studied the vibrations (seismic waves) generated by earthquakes to learn more about the structure of the earth's interior. They discovered that it is made up of these distinct layers: the crust, the mantle, the outer core, and the inner core. Students need to understand that the crust is the thinnest layer and the mantle is the thickest layer. Students worked with the Revolved 101 app and used lines of symmetry to make their layers of the Earth creations. Objectives Students should be able to identify the different layers of the Earth (crust, mantle, outer core, inner core). Students also need to understand that a line of symmetry will duplicate anything that is done on one side to the opposite side. Standards Virginia SOL: Virginia Standard Science SOL 5.7c The student will investigate and understand how the Earth's surface is constantly changing. Key concepts include : c) the basic structure of the Earth's interior; Common Core: E.8.C.3 Students know Earth is composed of a crust (both continental and oceanic); hot convecting mantle; and a dense, metallic core. E.8.C.4 Students know the very slow movements of large crustal plates result in geological events.https://www.oercommons.org/authoring/1440-moving-earth-plate-tectonics/view Lesson Plan and Activity In class students learn about the layers of the Earth. Throughout the unit, students identify and understand the different layers of the Earth and what each layer is made of: (crust, mantle, outer core, inner core) Students get an iPad and open the Revolved 101 app. Allow students about 10 minutes to play around with the app and learn how the line of symmetry creates the different shape and parts. Then students create a model in Revolved 101. Students need to make sure their Earth model shows the 4 distinct layers. These layers should also be proportional to each other. Once students finish the teacher needs to ensure that the creation has all of the components and is ready for printing. The teacher will then upload the .stl file to either a Google Drive, email address, or Dropbox account. The teacher will print the 3D model on their printer.

Skills Learned Symmetry Earth layers Duration of Lesson After students started learning about the Earth unit in class the actual 3D modeling and creating part took the students about 45 minutes to complete. Preparation Before beginning in Revolved 101 students need to understand the layers of the Earth. They must be able to explain the different proportions of each layer in relation to one another. Teachers need to download the Revolved 101 app (free app!) and give the students a few minutes to get familiar with it. Rubric and Assessment By the end of the project students should have designed the layers of the Earth including its important features. Students will get full credit on their 3D creations if they ensure that their Earth has all four layers and they are correctly proportioned.
