Our project titled ‘Keep Fit and Active – Be Healthy and Happy!’ promotes the importance of proper nutrition and underlines the benefits of exercise, the lack of which is nowadays a concern for a growing number of adolescents in the EU countries. Our work over the project will focus on raising awareness of active and healthy lifestyle as an investment for the future. Thus, in the first year we are going to carry out a questionnaire to make an assessment of the situation. Other activities will be addressed both to teenagers and their parents and aim at the proper habit of eating, concern for harmonious physical development and sensible use of modern technologies. In the first year, our cooperation will result in an end product about breakfast, because with the right nutrition from early on students can achieve better results. Students will also write articles about nourishment and physical exercise. Apart from that, we would like to walk a symbolic marathon route whose distance will reflect the distances between the partner countries of the project. The Olympic Games will be the idea lying behind the second-year actions. We are going to make a video film and a booklet with games involving physical movement derived from the tradition of our regions. The games, which can be played without a special equipment or sports facilities, enable students to spend free time in an active way. The peak activity will be the Comenius Olympics with these games. We will also collect a booklet of healthy recipes created with and by teenage cooks. The evaluation device will be a questionnaire, which helps us make conclusions about positive changes in thinking and the physical shape of the youth.
