Earth Layers

                             Lesson Overview

 Engage and explore Earth’s layers with a trade
  book
 Assess prior knowledge
 Use apple as a 3-D model for comparison to
  layers
 Identify and summarize the characteristics of
  each layer

                              Instructional Goals


STANDARD 9.0 Earth Features
  Describe, locate, and label the layers of the Earth
  by what they are made of, and by their physical
  properties.
 Accomplishment: 8.9.01a-Differentiate among
  earth layers according to their physical properties.
 8.9.spi.1 Label a cross section of the earth.
 8.9.tpi.1 Build a model that represents the earth’s
  layers.

                    Formative Assessment



 Carousel questions based on reading
  excerpt from trade book, Plate Tectonics
  by Rebecca L. Johnson
 Draw and label apple as model of earth
  layers
 Write characteristics of earth layers

              Lesson Organization: Opening The Lesson
                           (10 minutes)
 Hand out class set of typed or Xeroxed copies of second
  and third paragraphs from p. 6 of Plate Tectonics by
  Rebecca L. Johnson. Show an overhead transparency copy
  of the paragraphs to class and ask student to read aloud.
 Show a transparency of labeled earth layers showing 5
  layers of physical properties and 3 layers for composition
  (similar to diagram on p. 7 of trade book).
 Post large papers around classroom headed with diagram
  labels. Elicit questions generated by these paragraphs and
  have students write them on Post-it notes and then stick
  them under the appropriate poster headings. Students will
  cruise around room, reading questions, and posting
  answers to any questions they already know.
  (See directions for “Carousel Brainstorm” on the Tennessee’s Next Generation
  Tools for Teaching Standards Based Science CD.)

                                                                            6
          Lesson Organization: Developing The Lesson
                         (25 minutes)

 Hand out paper plates, drawing paper, and one-quarter
  wedges of apples to each student (or group).
 Ask students to decide which part of the apple represents
  the layers represented on the transparency diagram. Direct
  students to draw the apple wedge and label it with
  corresponding terms from transparency diagram. Under
  each label on the student drawing, write a sentence
  explaining why that apple part was chosen for that term.
 Use textbook or other resources to locate information
  about Earth layers. Write characteristics for each layer,
  including temperature, thickness, chemical composition,
  and other important information. Students will complete
  the apple diagram and list of characteristics for
  homework.

          Lesson Organization: Closing The Lesson
                        (5 minutes)


 Assign each student group a layer to summarize
  for the class. Each group gets a minute to reread
  the questions and answers already posted on large
  paper and the information they wrote on their
  diagram. Each group elects one member to
  summarize the information aloud for the class.
 Students throw out plates and uneaten apples,
  and use sanitizer and paper towels to clean up.

                                 Teacher Resources

 Teacher prep: Large paper sheets headed with Earth layer
  terms, Post-it Notes for every student, purchase one apple
  for every 4 students and paper plate for every student or
  group.
 Bruise apple before cutting into quarters to simulate crust
  and lithosphere.
 Need transparency of Earth layers and of paragraphs
  selected from trade book Plate Tectonics by Rebecca L.
  Johnson. Also make class set of copies of paragraphs
  selected from trade book. Drawing paper for each student.
  Hand sanitizer and paper towels for clean up.

                         Enrichment Activities

 Aside from an apple, what other material(s) can
  be used to create a 3-dimensional model of Earth's
  layers?
 Create a mnemonic device to remember the
  correct sequence of layers.
 Compare the movie “The Core” to today’s lesson.
  Determine which movie parts are fact and which
  are fiction.

    Accommodations For Special Learners


 Place weaker students in heterogeneous group so
  that peer tutoring can take place.
 Monitor students' involvement to keep
  easily-distracted students on task.

                             Assessment

You are a tour guide on a sightseeing
tour of the Earth's layers. You will
describe in a written brochure the
journey to the center of the earth.
Include information about the
composition and physical description of
the layers in your brochure. Your
product will be an oral or written guide
to the sights as they progress on the
journey.
