What is the interior of the Earth like? Are the rocks that form the core and the crust the same? In this activity, we will travel to the interior of the Earth to find out about its composition and discover, through experimentation, what the rocks that make up the geosphere are like. We will then learn to distinguish them from minerals and recognize the different types of rocks according to the process of formation. We will then investigate the different characteristics and properties of minerals (colour, hardness, streaks, opacity, etc.) through observation and experimentation.
Finally, we will reflect together on the social, economic, and environmental impact of the anthropic exploitation of rocks and minerals over the years and we will learn about the specific case of clay extraction in La Garrotxa.
