Home/School Liaison

The recommendations

Pupils should be encouraged to share good practice between home and school.
Schools should consider the benefits of sharing their policies and practice on Internet access and use with parents.
The support of parents should be sought.
The Click Thinking as a Family Resource can be photocopied and distributed for home use.
Where School Boards are in place, these bodies may be instrumental in forging good Internet liaison between school, parents and the community. School Boards should consider including discussion of children's use of the Internet at open forums for parents such as their AGM.
School handbooks should include information on Internet policies and practice, and also refer parents to the Local Authority, the school or the website for copies of the Click Thinking as a Family Resource.

Oil painting

Oil painting is the process of painting with pigments that are bound with a medium of drying oil -particularly in early modern Europe, linseed oil. Often oil such as linseed was boiled with a resin such as pine resin or even frankincense; these were called 'varnishes' and were prized for their body and gloss. Other oils infrequently used include poppy seed oil, walnut oil, and safflower oil. These oils confer various properties to the oil paint, such as less yellowing or different drying times. Certain differences are also visible in the sheen of the paints depending on the oil. Painters often use different oils in the same painting depending on specific pigments and effects desired. The paints themselves also develop a particular feel depending on the medium.

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.
