Physical activity can be a preventive measure for several lifestyle diseases and essential about children’s development and growth. The school ground is a place where children spend countless hours and can, therefore, be a great arena for promoting physical activity and health. There are several positive correlations between having green spaces in the school ground and children’s physical activity in the existing literature. The green spaces in the school grounds are important for the children, as it was one of the two places where most children were physically active. The respondents perceived the effect of green spaces show that both the parent group and the school officials view green spaces in the school ground as very positive in terms of promoting physical activity, more constructive play, more cooperative play, more civil play behaviour and encourages the students to explore the natural environment. Both the parents and the school officials rated exploring nature as the number one encouraging factor in terms of physical activity. The school ground is for many children a place to play, explore, learn and develop. Several children prefer to play in natural environments, like nature and wild spaces, the green school ground gives children great conditions and opportunities to play, learn and explore nature. As such green space located within schoolyards varies, while findings support a clear correlation between physical activity, health, active play, child development and green spaces and also brings to light benefits from having green spaces in the school ground. According to the children, green space is their favourite place within the school grounds because of all the opportunities they have in the green spaces. These opportunities provide the children with a creative playground, where they could use their imagination and practical skills. One of the clear difference is that the children in the school who are surrounded by the natural environment spent much more time outside and were more active than the other children. The green school ground promoted more civil play behaviour, more constructive play, more imaginative play and more active play. By allowing the students to explore nature, the school ground was encouraging the children to be more active. The design of the school ground is a very important factor in terms of the effectiveness of the green school grounds. Thus green spaces in the school ground have a very positive impact on the children and are, therefore, an essential feature to have in a school ground in terms of the children’s health and well-being, but also in terms of quality of play and the children’s experiences.
