Memorandum

Kleure: Groen/geel bo, bruin en blou links en regs (lg. twee kan omruil).

Aarddraad: Lei stroom af sodat daar nie oorverhitting ontstaan nie/laat aard-lekkasieskakelaar uitskop om stoof af te sny. Anders kan brand ontstaan of kan persoon doodgeskok word.

Teken: Gevaar. Elektrisiteitinstallasies is gevaarlik. Nie net skokke nie, maar bestraling/magneetvelde is skadelik vir die mens.

Inhoud

Aktiwiteit: om die internasionale kleurkode vir bedrading te kan beskryf en toepas, en om die veiligheidsmaatreëls by die gebruik van elektrisiteit te kan opnoem [lu 1.2, lu 1.3, lu 2.3]

  • Die drie-aar-elektriese draad bestaan uit drie geleiers, elk met sy kenmerkende kleur. Elke geleier het sy eie funksie. Die kleure van die drie geleiers in die draad word in byna alle lande gebruik en staan bekend as die internasionale kleurkode .

Kragproppe behoort volgens die internasionale kleurkode bedraad te word.

  • Die blou draad is die neutrale geleier en gelei elektrisiteit vanaf die apparaat na die kragbron.
  • Die bruin draad is die lewendige geleier en gelei elektrisiteit vanaf die kragbron na die apparaat.
  • Die geel-en-groen draad is die aarddraad en gelei oormatige elektrisiteit weg in die geval van ‘n kortsluiting.

Jul onderwyser sal ‘n kragprop wat korrek bedraad is aan julle wys. Maak seker dat julle weet presies waar elkeen van die geleiers vasgeskroef moet word, anders kan die toestel lewensgevaarlik wees as iemand daaraan sou raak.

Gebruik die toepaslike kleur en dui aan hoedat jy die prop in die volgende skets sal bedraad.

  • Doen navorsing en vind uit hoekom die aarddraad belangrik is. Verwys ook na die aardlekkasieskakelaar op die skakelbord by julle huis.

  • Elektrisiteit is gevaarlik. Onthou die volgende veiligheidsmaatreëls as jy met elektrisiteit werk:

- Moet nooit ‘n elektriese apparaat wat stukkend is, self probeer regmaak nie. Vra liefs ‘n opgeleide elektrisiën om die herstelwerk te doen.

- Water is ‘n goeie geleier van elektrisiteit. Moet dus nooit met elektrisiteit werk terwyl jy naby water staan nie.

- Moenie ‘n kragprop uit ‘n kragsok trek deur aan die draad te pluk nie.

- Maak seker dat jy weet waar die gebou se hoofskakelaar sit. Wanneer iets verkeerd gaan, kan jy onmiddellik die hoofstroom afskakel.

- Pasop om elektriese drade onderdeur matte aan te lê. Dit is baie moeilik om die toestand van die drade te ondersoek, indien dit nie te alle tye sigbaar is nie.

VDit is ‘n goeie beleid om elektriese apparate van tyd tot tyd deur ‘n gekwalifiseerde elektrisiën te laat ondersoek.

Assessering

Leeruitkomste 1: Die leerder is in staat om met selfvertroue op weetgierigheid oor natuurlike verskynsels te reageer, en om binne die konteks van wetenskap, tegnologie en die omgewing verbande te ondersoek en probleme op te los.

Assesseringstandaard 1.2: Dit is duidelik wanneer die leerder ondersoeke uitvoer en data versamel;

Assesseringstandaard 1.3: Dit is duidelik wanneer die leerder data evalueer en bevindings kommunikeer.

Leeruitkomste 2: Die leerder ken, interpreteer en pas wetenskaplike, tegnologiese en omgewingskennis toe.

Assesseringstandaard 2.3: Dit is duidelik wanneer die leerder inligting interpreteer.

why is communication effective
Dakolo Reply
Communication is effective because it allows individuals to share ideas, thoughts, and information with others.
effective communication can lead to improved outcomes in various settings, including personal relationships, business environments, and educational settings. By communicating effectively, individuals can negotiate effectively, solve problems collaboratively, and work towards common goals.

Every time someone flushes a toilet in the apartment building, the person begins to jumb back automatically after hearing the flush, before the water temperature changes. Identify the types of learning, if it is classical conditioning identify the NS, UCS, CS and CR. If it is operant conditioning, identify the type of consequence positive reinforcement, negative reinforcement or punishment

because it helps many people around the world to understand how to interact with other people and understand them well, for example at work (job).

explain how nature and nurture affect the development and later the productivity of an individual.
Amesalu Reply
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills

Magret Reply
hello. autism is a umbrella term. autistic kids have different disorder overlapping. for example. a kid may show symptoms of ADHD and also learning disabilities. before treatment please make sure the kid doesn't have physical disabilities like hearing..vision..speech problem. sometimes these

continue.. sometimes due to these physical problems..the diagnosis may be misdiagnosed. treatment for autism. well it depends on the severity. since autistic kids have problems in communicating and adopting to the environment.. it's best to expose the child in situations where the child
Jharna
child interact with other kids under doc supervision. play therapy. speech therapy. Engaging in different activities that activate most parts of the brain.. like drawing..painting. matching color board game. string and beads game. the more you interact with the child the more effective
Jharna
results you'll get.. please consult a therapist to know what suits best on your child. and last as a parent. I know sometimes it's overwhelming to guide a special kid. but trust the process and be strong and patient as a parent.
