Geskiedenis

Graad 4

Geskiedenis begin in ons eie omgewing

Module 3

Dis tyd om my omgewing beter te verstaan

Tyd is waarskynlik die belangrikste begrip in geskiedenis. as jy goeie begrip van tyd het, verstaan jy die verlede van jou omgewing soveel beter. die volgende aktiwiteit gaan jou hiermee help!

Snuffeltakies

Aktiwiteit 1

Om oorsake en gevolge te verskaf [lu 2.3]

a) Lees nou die volgende instruksies uit Linda Gouws se briefie oor hoe om vir jouself ‘n kussing te maak.

  • Kan jy agterkom watter stap sy per ongeluk uitgelaat het?
  • Wat sal die gevolg daarvan wees?

(b) Hou ‘n klasgesprek oor die oorsake waarom sekere mense in jul omgewing gelukkig/ongelukkig is. Watter gevolge het dit in die gemeenskap?

Aktiwiteit 2

Om tussen verskillende tydperke te onderskei [lu 2.3]

Ouma Sophia teken graag. Sy het deur die jare ‘n reeks prente geteken van hoe Mooimeisiesfontein ontwikkel het.

  • Rangskik eers haar prente in die regte volgorde.
  • Van watter stadium van ontwikkeling sou jy die meeste en die minste gehou het? Waarom?

Aktiwiteit 3

Om tyd te verstaan [lu 2.2]

Assessering

Leeruitkoms 2: geskiedkundige kennis en begrip

Die leerder is in staat om geskiedkundige kennis en begrip te toon.

Assesseringstandaard

Dis duidelik wanneer die leerder

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
