Creating healthy habits in our pupils is part of our daily work, but, do they really know what does it mean? Thanks to this project they'll became detectives to discover lies and trues about healthy food, healthy habits, physical exercise and activities to get a healthy body in a healthy mind. Through three items ( Fitness – exercise – sports; Healthy diet – nutrition; Good psychology) our pupils will identify good and not so good habits in different countries, they will know their own difficulties in having healthy habits and they will use this information to teach their families and friends.
