This is the second year that we carry out this project, which consists in inculcating healthy life habits among the youngest. Each year we go to a different primary school to carry out interactive activities with children from 3 to 12 years old. Students learn the importance of the kidneys in our body through educational videos, their own research and experiments carried out in the classroom. The little ones adopt a teddy kidney and take care of it according to the habits acquired thanks to the childish story “The twins go to Doctor” and other practical exercises. A white T-shirt is given to each student in which they are invited to express with colorful slogans about the health of the kidneys from what they have learned.
