Blood's destiny is to circulate is a project whose aim is to increase our students' awareness on the importance of becoming blood donors. This good practice is still used in some schools that organise blood donations days and in doing so they develop the students' sensitivity on this topic. Putting this good practice in an etwinning project can be an added value because students can cooperate and share experiences with other countries' students for a better understanding of the importance of the blood donation and of how this common practice can save lives.
