Assessering

LU 1

WETENSKAPLIKE ONDERSOEK 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.

Dit is duidelik wanneer die leerder:

1.1   ondersoek beplan;

1.2   ondersoek uitvoer en data versamel;

1.3       data evalueer en bevindings kommunikeer.

 

Memorandum

Habitat van plante:

  • water: sommige groei onder water en ander groei bo-op die water
  • woestyne: Sommige kan in woestyne groei waar dit warm en droog is en waar water skaars is: kaktusse, vygies
  • berge: hulle moet bitter koue en sterk winde kan trotseer: kosmos, bitterbosse, disa, protea, suikerbos
  • oerwoud: orgideë, varings, mos
  • veld: fynbos, sommige proteas
  • botaniese tuine: gewoonlik inheemse plante
  • semi-woestyn: karoobossies, kaktusse
  • enige ander aanvaarbare antwoord

Beantwoord die volgende vrae:

  1. sonlig, warmte, water
  2. goedgedreineerde, leemgrond vol kompos
  3. koolstofdioksied
  4. Ja

Voëlkoekie om voëls na die tuin te lok

  • Maak ‘n gaatjie aan die onderkant van ‘n 500 ml joghurtbakkie.
  • Steek ‘n stukkie tou van ongeveer 20 cm lank deur die gaatjie en maak ‘n knoop daarin.
  • Maak die kos vir die voëltjies en sit dit binne-in die bakkie. Die kos word so gemaak: smelt ongeveer 125 g vet in ‘n pan en gooi allerhande sade, soos sonneblomme, koring, voëlsaad, neute, harde broodkrummels, hawermout, ens. daarin en meng dit goed. Wag tot dit effens afgekoel het en gooi dit dan in die houer.
  • As die vet hard geword het, haal dit uit die houer en hang dit aan die boom.Hou die voëls lekker dop!

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

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 ◀️
