Memorandum

Stowwe wat genoteer word, sal bepaal word deur watter voorwerpe die leerders gebruik.

Voltooi:

  • Magnetiese stowwe.
  • Yster, staal, nikkel of kobalt.
  • Nie-magnetiese stowwe.
  • Kurk; plastiek; koper en karton.

Leerder afdeling

Inhoud

Aktiwiteit: om magnetisme in verskillende stowwe te toets [lu 1.2, lu 1.3, lu 2.1]

Neem ‘n verskeidenheid voorwerpe. Elke lid van die groep bring voorwerpe van die huis af om te toets. Noteer jul bevindings in die volgende tabel.

Voltooi:

‘n Magneet sal magnetiese stowwe aantrek. Al die voorwerpe wat dus deur

die magneet aangetrek is, word ____________________________________ genoem

en is gemaak van stowwe wat _____________________, ______________________

_____________________________________of ________________________ bevat.

Die voorwerpe wat nie deur die magneet aangetrek is nie, word __________________

________________________genoem en is gemaak van stowwe soos ________________________, ________________________,_________________ en

Let baie mooi op wanneer jou opvoeder die volgende demonstrasie doen:

Assessering

Leeruitkomste 1: 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.

Assesseringstandaard 1.2: Dit is duidelik wanneer die leerder ondersoeke uitvoer en data versamel: organiseer en gebruik toerusting of bronne om inligting in te versamel en aan te teken;

Assesseringstandaard 1.3: Dit is duidelik wanneer die leerder data evalueer en bevindings kommunikeer: veralgemeen ten opsigte van ‘n relevante aspek en beskryf hoe die data die veralgemening steun.

Leeruitkomste 2: Die leerder ken, interpreteer en pas wetenskaplike, tegnologiese en omgewingskennis toe.

Assesseringstandaard 2.1: Dit is duidelik wanneer die leerder betekenisvolle inligting onthou: onthou, ten minste, definisies en komplekse feite.

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,
