Assessering

LU 2

Wetenskaplike Kennis

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

Dit is bewys as die leerder:

2.1 sinvolle inligting kan onthou;

2.2 inligting in kategorieë kan plaas;

2.3 inligting kan interpreteer;

2.4 kennis kan toepas.

LU 3

Wetenskap, die Gemeenskap en die Omgewing

Die leerder is in staat om begrip van die onderlinge verband tussen wetenskap en tegnologie, die samelewing en die omgewing te toon.

Dit is bewys as die leerder:

3.1 wetenskap as ‘n menslike aktiwiteit kan verstaan;

3.2 volhoubare gebruik van die aarde se hulpbronne verstaan.

KLASBESPREKING

Kan diere skadelik wees vir die omgewing?

  • Ja – veral oorbeweiding lei tot verlies van plante wat lei tot erosie. Uitheemse diere kan skadelik wees aangesien hulle natuurlike vyande nie teenwoordig is nie en hulle getalle dus in so ’n mate groei dat hulle die inheemse diere verdring en oorneem. Dit kan tot die uitroeiing van bepaalde dier- en plantsoorte lei.
