Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

5. Die oordrag van energie

(a) Geleiding

Geleiding vind plaas wanneer warmte deur vaste stowwe beweeg. Hou ‘n stuk draad in ‘n vlam. Wat gebeur na ‘n rukkie?

Die hitte is deur middel van geleiding in die draad na jou hand oorgedra. Metale soos koper, yster en aluminium is beter geleiers as nie-metale soos hout, water en kurk. Sekere metale gelei hitte vinniger as ander.

Plak of teken sulke materiale hier.

Assessering

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

Assesseringstandaard 2.3: Dit is duidelik wanneer die leerder inligting interpreteer, bv.: interpreteer inligting deur kernidees in die teks te identifiseer, patrone in aangetekende data te vind en gevolgtrekkings te maak uit inligting in verskeie vorme (bv. prente, diagramme en geskrewe teks).
