Volunteering in Ghana

Help on a Kidz Active school and in a Ghanaian village ! Dear family , friends and other nice people , During the Christmas holidays I go with Voluntary Worldwide two weeks to Ghana, Africa to volunteer as a Kidz Active school and to help in a Ghanaian village . Furthermore, I will do some excursions . Except for the trip and the ticket should I get vaccinations, visas and apply for a passport . Also I like what can do for the people and children there. In what form it will be ( for school books , games , etc.) is still being discussed with the organization. Together, all this of course will cost a lot of money and that is why I need your help ! I 'm totally not mind to do something , but obviously voluntary donations are also welcome , every euro helps !
