Graad 4

Materie en stowwe

Module 56

Die waarde van boumateriaal as 'n hulpbron

Aktiwiteit:

Om die waarde van boumateriaal as ‘n hulpbron in die bou van huise te leer ken

[lu 1.2.1, 2.2.1, 3.2]

Boumateriale

Wanneer ‘n huis gebou word, word materiale gebruik wat natuurlik is of wat gemaak moes word. Hier is ‘n prentjie van ‘n huisie. Kleur die natuurlike materiale geel in en die ander materiale rooi.

Hout

Een van die natuurlike produkte wat gebruik is om die huisie te bou, is hout.

Hout is ‘n wonderlike hulpbron vir die mens. Deel die klas in ses groepe. Gee drie minute kans om alles te lys wat van hout gemaak is in die:

klas

jou kamer by die huis

jou sitkamer by die huis

die kombuis

op die skoolterrein

I

in die skoolsaal

1. Watter gevolgtrekking kan jy hieruit maak?

My gevolgtrekking is: ____________________________

  1. Skryf aan Sappi om plakkate aan julle klas te stuur.

Bakstene

Om mee te skryf

Duisende jare gelede het mense allerhande maniere gebruik om te skryf. Hulle het materiale van dierprodukte, klippe, plante en klei gebruik. Hulle het op papirus, bas, dierevelle en rotse geskryf en tekeninge gemaak.

Vandag is dit baie makliker. Ons gaan net eenvoudig winkels toe en koop die wonderlikste skryfgoed wat ons wil hê. Al hierdie goed word van verskillende soorte materie gemaak.

Dink aan iemand uit ons verre verlede wat jou nog altyd gefassineer het. Stuur ‘n kort SMS-boodskap aan hom/haar om te bewys hoe die tegnologie oor ‘skryf’ deur die jare verander het.

Assessering

LEERUITKOMS 1: WETENSKAPLIKE ONDERSOEK

Die l eerder 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.

Assesseringstandaard

Dis duidelik wanneer die leerder

1.2 ondersoeke uitvoer en data versamel, bv.:

1.2.1 merk ooglopende veranderings of interessante besonderhede op en lewer kommentaar daarop.

LEERUITKOMS 2: KONSTRUKSIE VAN WETENSKAPKENNIS Die leerder ken, interpreteer en pas wetenskaplike, tegnologiese en omgewings- kennis toe.

Assesseringstandaard

Dis duidelik wanneer die leerder

2.2 inligting kategoriseer, bv.:

2.2.1 volg instruksies om diere in groepe van dié met twee bene, met vier bene en met meer as vier bene te sorteer.

LEERUITKOMS 3: WETENSKAP, DIE SAMELEWING 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 .

Assesseringstandaard

Dis duidelik wanneer die leerder

3.2 die impak van wetenskap en tegnologie verstaan.

Memorandum

Boumateriale:

  • Natuurlike materiale: kleur dit geel in
  • Ander materiale: kleur dit rooi in

Om mee te skryf:

  • Kinders ken nie die outydse maniere van skryf nie. Indien daar tyd is, lees outydse artikels, stories of kyk video’s wat dit mooi uitbeeld.
  • Die SMS-boodskap is iets wat hulle baie goed ken!

lack electricity and its more savely than electronic microscope because its naturally by using of light
Abdullahi Reply
advantage of electronic microscope is easily and clearly while disadvantage is dangerous because its electronic. advantage of light microscope is savely and naturally by sun while disadvantage is not easily,means its not sharp and not clear

in what situation (s) would be the use of a scanning electron microscope be ideal and why?
Kenna Reply
A scanning electron microscope (SEM) is ideal for situations requiring high-resolution imaging of surfaces. It is commonly used in materials science, biology, and geology to examine the topography and composition of samples at a nanoscale level. SEM is particularly useful for studying fine details,
