From BBC documentary film "Earth The Power Of The Planet "
This topic explains the inner layers of the earth's crust and how the earth looks like on both the inside and the outside.0:00 - Inside our Earth0:44 - Crust...
We know what the layers of the Earth are without seeing them directly -- with the magic of geophysics.


The lesson is about designing and printing the composition of the earth in order to understand how the earth was formed and how it is composed. It will also develop students understanding of the different layers and parts of the earth. Students will also understand the location of the Earth within the solar system.  other than to locate it in the solar system. Students will also understand the 3D printing techniques.

Learning objectives

The students will be able to:
– Design the earth composition with Rihnoceros or Sketchup or Inventor Educational or with other suitable CAD software.
– Identify the different parts of the earth (layers).
– Know and locate the earth in the solar system framework.
– Know the earth dimension and the temperature.
– Prepare CAD files to be printed.
– Learn 3D printing technics.
– Setting the 3D printing file.
– Print the 3D model of the earth composition.

Teacher preparation

Preparation about the guided lesson in the classroom. To plan exercises that could be developed during the classroom lesson in order to make the lesson as interactive as possible.

Teacher explanation

– Introduce the topic and the objective (the concept of the earth and its origin).
– Explain the basic of the 3D software for Rhinoceros or Sketchup or Inventor Educational.
– Guided designing of the earth composition.
– Explain how to save the file and how to export to the suitable format for the 3D print (.STL, .OBJ…).
– Explain the basic about 3D printing
– Explain how to set the file on the coding software, Cura.
– Show how to obtain the G-code.
– Explain how to prepare the 3D printer for launching works

Student activity/Steps

Design the earth composition map with some sketch and then using to the CAD software Rhinoceros or Sketchup or Inventor Educational.
– Saving and exporting to the suitable format, STL. OBJ….
– Select the suitable setting on Cura for printing the model
– Launching the file on the 3D printer.
– Try the design.
– Participate to the exercises proposed by the teacher (both practical and theoretical).
