Inhoud

Aktiwiteit: om eenvoudige vrae te vra en relevante data te identifiseer [lu 5.1]

Om data te versamel en vrae te beantwoord [lu 5.2]

Om data te organiseer en aan te teken [lu 5.4]

Om data te ondersoek om die sentrale neiging te beskryf [lu 5.5]

Om grafieke te teken [lu 5.6.1/2]

Om data krities te lees en te interpreteer [lu 5.7.2]

** Hierdie is ‘n taak vir jou portefeulje.

Werk so netjies soos jy kan, maar kyk eers hoe jou taak geassesseer gaan word.

1. Kom ons kyk na die ontbytgewoontes van jou klasmaats. Vra die leerders in jou klas wat hulle vir ontbyt eet.

2. Maak ‘n opnameblad van die inligting wat jy versamel het in die blok hieronder:

Byvoorbeeld:

GRAAD 6
ONTBYT AANTAL LEERDERS

Beskuit 6
Graankos 3

3. Jy het reeds kennis gemaak met ‘n verskeidenheid grafieke. (Onthou jy nog?) Kyk of jy die inligting hierbo op ‘n grafiek kan aanteken:

4. Vind nou uit WATTER pap die gewildste onder jou klasmaats is.

_____________________________________________________________________

5. Vind ook uit wat die prys daarvan per boks / houer is en bereken wat jy sal moet betaal as jy EEN daarvan vir ELKE leerder in jou klas wil koop.

6. Skryf nou ’n kort verslaggie oor jou navorsing i.v.m. jou klasmaats se ontbytvoorkeure en -gewoontes.

Assessering

Leeruitkomste 5: Die leerder is in staat om data te versamel, op te som, voor te stel en krities te ontleed om gevolgtrekkings en voorspellings te maak, en om toevallige variasies te interpreteer en te bepaal.

Assesseringstandaard 5.1: Dit is duidelik wanneer die leerder eenvoudige vrae stel oor sy/haar eie skool en gesinsomgewing, en gepaste databronne vind ten einde menseregte, sosiale, politieke, kulturele omgewings- en ekonomiese kwessies in daardie omgewing te identifiseer;

Assesseringstandaard 5.2: Dit is duidelik wanneer die leerder eenvoudige dataversamelingsvelle (wat tellings vereis) en eenvoudige vraelyste (met ja/nee tipe antwoorde) gebruik om data te versamel (alleen en/of as ‘n lid van ‘n groep of span) ten einde vrae te beantwoord wat deur die onderwyser, self of die groep gevra word;

Assesseringstandaard 5.4: Dit is duidelik wanneer die leerder data organiseer en aanteken deur gebruik te maak van tellings en tabelle;

Assesseringstandaard 5.5: Dit is duidelik wanneer die leerder ongegroepeerde numeriese data ondersoek om die telling (modem) wat die meeste voorkom, en die middelpunt (mediaan) van die datastel te bepaal, om sodoende sentrale neigings te beskryf;

Assesseringstandaard 5.6: Dit is duidelik wanneer die leerder ‘n verskeidenheid van grafieke met die hand of tegnologies teken om data voor te stel en te interpreteer (gegroepeer of ongegroepeer), insluitend:

5.6.1: prentdiagramme (piktogramme) met ‘n veel-tot-een-ooreenstemming en ‘n geskikte sleutel;

5.6.2: staafgrafieke en dubbele staafgrafieke;

Assesseringstandaard 5.7: Dit is duidelik wanneer die leerder data wat op verskillende wyses voorgestel word (insluitend eie voorstellings, mediavoorstellings – woorde, grafieke, sirkeldiagramme), krities lees en interpreteer om sodoende afleidings te maak en voorspellings te maak wat sensitief is teenoor die rol van:

5.7.2: afdelings binne die data (bv. ouderdom, geslag, ras).

explain assimilatory nitrate reduction
Esinniobiwa Reply
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
