physical mastery and self-development. It can be seen that playgrounds provide an ideal opportunity for children to master physical skills, such as learning to swing, balance and climb. Personal development may be gained through the enhancement of skills, such as playing, communicating and cooperating with other children and adults in the playground. It can also be seen that public and private playgrounds act as a preventative health measure amongst young people because they promote physical activity at a stage in children's lives when they are active and not yet at risk from opting out of physical activity. Children have devised many playground games and pastimes. But because playgrounds are usually subject to adult supervision and oversight, young children's street culture often struggles to fully thrive there. Research by Robin Moore concluded shown that playgrounds need to be balanced with marginal areas that (to adults) appear to be derelict or wasteground but to children they are areas that they can claim for themselves, ideally a wooded area or field. For many children, it is their favorite time of day when they get to be on the playground for free time or recess. It acts as a release for them from the pressures of learning during the day. They know that time on the playground is their own time. A type of playground called a playscape can provide children with the necessary feeling of ownership that Moore describes above. Playscapes can also provide parents with the assurance of their child's safety and wellbeing, which may not be prevalent in an open field or wooded area. Funding In the UK, several organisations exist that help provide funding for schools and local authorities to construct playgrounds. These include the Biffa Award, which provides funding under the Small Grants Scheme; Funding Central, which offers support for voluntary organisations and social enterprises; and the Community Construction Fund, a flagship programme by Norfolk County Council. Safety Safety, in the context of playgrounds, is generally understood as the prevention of injuries. Risk aversion and fear of lawsuits on the part of the adults who design playgrounds prioritizes injury prevention above other factors, such as cost or developmental benefit to the users. It is important that children gradually develop the skill of risk assessment, and a completely safe environment does not allow that. Sometimes the safety of playgrounds is disputed in school or among regulators. Over at least the
