Energie en verandering

Module 36

Probleme met elektriese toestelle

Aktiwiteit:

Om probleme wat sommige mense met die gebruik van elektriese toestelle kan ondervind te identifiseer en op te los

[lu 3.3]

Werk in groepe. Dink aan verskillende redes waarom gestremdes, ouer of jonger mense, of blindes, dit moeilik mag vind om met elektrisiteit te werk.

Skryf ‘n paar sinnetjies oor watter plannetjies jy sal maak om dit vir so ‘n persoon meer gerieflik te maak.
