Body of Lesson
Show the students the globe. Define the term diameter, then tell them that the Earth’s diameter is about 12,760km or about 7,900 miles. Put this distance in context by comparing it to a distance students are familiar with, such as the distance from their town or city to a distant, but familiar location.
Guided Practice 1
Explore students’ ideas about the inside of the Earth. Is it the same all the way to the center? Distribute art supplies and ask them to draw what they think the inside of the Earth is like, then write a paragraph describing the drawing. (This activity will help you to know what background they are bringing to the topic.)
Distribute a graph of the Earth's Layers. Ask students to color each of the Earth’s layers a different color. Color the area from the beginning of the lithosphere out to the surface yellow, then go over the outermost section with blue to indicate the crust. (The overlapping colors, which should produce green for the crust, will help students to understand that the crust is part of the lithosphere.)
Ask students to discuss what they learned.<!- mfunc search_btn -> <!- /mfunc search_btn ->
