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.

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.

is it possible to leave every good at the same level

I don't think so. because check it, if the demand for chicken increases, people will no longer consume fish like they used to causing a fall in the demand for fish

is not really possible to let the value of a goods to be same at the same time.....

Suppose the inflation rate is 6%, does it mean that all the goods you purchase will cost 6% more than previous year? Provide with reasoning.
Geetha Reply
Not necessarily. To measure the inflation rate economists normally use an averaged price index of a basket of certain goods. So if you purchase goods included in the basket, you will notice that you pay 6% more, otherwise not necessarily.

hi can someone help me on this question If a negative shocks shifts the IS curve to the left, what type of policy do you suggest so as to stabilize the level of output? discuss your answer using appropriate graph.
Galge Reply
if interest rate is increased this will will reduce the level of income shifting the curve to the left ◀️
