Generally everyone can volunteer no matter the age, race and gender. Nevertheless, the volunteering activity should be in line with the abilities and preferences of a certain age group.
Children can volunteering by planting flowers, picking up trash or taking care of animals in a shelter. Those activities are usually one-time, hands on activities.
Youth is already able to get involved in more time consuming activities which are occasional or even ongoing, however the activity as such should be also action related. Allowing to see imminent results and feel satisfaction from the accomplished task will eventually lead to the motivation to do more. However, as for children, support from a volunteering coordinator is essential. The coordinator should also provide recognition and allow to celebrate the involvement of the youth.
