LU 1

WETENSKAPLIKE ONDERSOEK 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.

1.2   ondersoeke uitvoer en data versamel;

1.3       data evalueer en bevindinge kommunikeer;

 

Memorandum

  • Die belangrike is dat die leerders self dink en antwoorde waag, bv.
  • voëls kan slegs sekere tye van jaar nes maak in ‘n bladwisselende boom.
  • bladwisselende bome verskaf slegs sekere tye van die jaar voedsel aan insekte.
  • die grond onder ‘n bladwisselende boom is dalk droër en harder as onder ‘n bladhoudende boom.
  • ‘n bladhoudende boom verskaf altyd skaduwee aan plante en diere wat daarvan hou, ens.
