Discovering Human Body



DISCOVERING HUMAN BODY
I observe – test - learn

The “Ignoto Militi” Primary School’s students (classes V A and V B) begin a journey to discover human body. 



The students create the smallest part of the human body: the CELL; they observe it and how nutriments pass through the cell membrane.




A plastic bag contains water and flour; a jar contains tincture of iodine diluted in water
 

The plastic bag behaves as a cell membrane: only the smallest molecules can pass through it.

The journey continues…DIGESTIVE SYSTEM
 


In a group work, the students handle a plastic cups, vinegar, bicarbonate and detergent and they create and personalize different models of Digestive System.
