Policies for Schools

Schools should have Acceptable Internet Use Policies, for pupils and for staff.Policies should take into account supervised and unsupervised use, both during school time and also out with school hours.These policy documents should include a clear section about the school's responsibilities regarding publishing pupils' information on a school website.
Policies should include reference to Child Protection procedures.Guidelines for Internet use should be displayed in obvious places, perhaps on the sides of the computers themselves.
Any guidelines that are developed within the school should be shared with others to increase networking and make efficient use of resources.

Painting

Painting is the practice of apply color to a surface (support) such as, e.g. paper, canvas, wood, glass, lacquer or concrete. However, when used in an artistic sense, the term "painting" means the use of this action in combination with drawing, composition and other visual considerations in order to manifest the expressive and conceptual intention of the practitioner.

Paintings are used as a mode of representing, documenting and express all the varied intents and subjects that are as numerous as there are practitioners of the craft. Paintings can be naturalistic and representational as in a still life or landscape painting, photographic, abstract, be loaded with narrative content, symbolism, emotion or be political in nature. A large portion of the history of painting is dominated by spiritual motifs and ideas; sites of this kind of painting range from artwork depicting mythological figures on pottery to biblical scenes rendered on the interior walls and ceiling of The Sistine Chapel to depictions of the human body itself as a spiritual subject.

Electric car

An electric car is a vehicle that makes use of by chemical energy stored in rechargeable battery packs, and electric motors and motor controllers instead of an internal combustion engine (ICE).

Vehicles using both electric motors and Ices (hybrid electric vehicles) are examples of hybrid vehicles, and are not deliberate pure electric vehicles (EVs) because they operate in a charge-sustaining mode. Hybrid vehicles with batteries that can be charged externally to displace some or all of their ICE power and gasoline fuel are called plug-in hybrid electric vehicles (PHEV), and are pure battery electric vehicles (BEVs) during their charge-depleting mode. Electric vehicles include automobiles, light trucks, and neighborhood electric vehicles.

Electric cars were among the earliest automobiles. They produce no exhaust fumes, and minimal pollution if charged from most forms of renewable energy. Many are capable of stepping up exceeding that of conventional vehicles, are quiet, and do not produce noxious fumes. Electric cars reduce dependence on petroleum and decrease or eliminate greenhouse gas emissions, depending on how their electricity is produced.
