The Layers of the Earth

STANDARDS: 12.F.1a Identify and describe characteristics of the sun, Earth and moon as familiar objects in the solar system. WIDA Standard 4: Label features of the Earth based on diagrams or models. Earth Science  THEME: Earth's Layers  LESSON TOPIC:   OBJECTIVES:   Language: Students will discuss what they believe the Earth is made of. Students will listen and look the teacher's presentation of other things that have layers. Students will write the name of each layer on their paper model. Students will read about the layers of the Earth and answer questions about the reading for homework. Content: Students will be able to label the 4 layers of the Earth. Students will be able to name what each layer is made of. LEARNING STRATEGIES:  inner core, outer core, mantle, crust   KEY VOCABULARY: apple, onion, knife, appropriate worksheets, construction paper circles  MATERIALS:  ||
 * MOTIVATION:

(Building background) Ask the students what they believe the Earth is made of. Allow them to share with their partner, then share with the class.

PRESENTATION: (Language and content objectives, comprehensible input, strategies, interaction, feedback) Slice an onion in half and walk around the room to show the students the inside. Allow them to share their observations with the class. Affirm that an onion has many layers, one very thin layer on the outside and a core piece in the very middle. Next, slice an apple in half. Allow the students to make observations about the apple, noting the thin outside (skin) and the core. Next, compare the onion and the apple to the Earth, making sure the students understand that they all have LAYERS.Then, draw a diagram on the board of the Earth. Explain that the Earth has 4 layers. Label each layer and tell what it is made of. (Crust:Rock, Mantle: Rock, Outer Core: Nickel and Iron, Inner Core: Nickel and Iron). Explain that the crust is the only layer that is not hot all the way through.

PRACTICE AND APPLICATION: (Meaningful activities, interaction, strategies, practice and application, feedback) Pass out construction paper and have students cut out the different colored circles. Show them the example that you have already made of the cross-section of the Earth. Allow students to glue the circles to each other, beginning with the largest (green) and ending with the smallest (orange). Intruct students to label the model with each layer's name. REVIEW AND ASSESSMENT: (Review objectives and vocabulary, assess learning) We will review the key concepts in class, and students will complete a multiple-choice assessment in partners. EXTENSION:  Students will take home extra reading about the Earth's layers to read and complete the attached questions. ||
