  • Merk die toepaslike kolom met ’n regmerkie:
Ja Sukkel nog
Ek kon die inligting by 14.1 deur middel van ’n lyngrafiek voorstel
Ek kon ’n sirkelgrafiek trek by 14.2
Ek kon die aantal stemme in die verkiesing by 14.3 korrek met ’n piktogram voorstel
Ek kon ’n kolomgrafiek by 14.4 teken
Ek kon ’n dubbele kolomgrafiek korrek by 14.5 teken
Ek kon die vrae by 15.1 in verband met tyd korrek beantwoord
Ek kon die gegewe skaal by 15.2 korrek interpreteer en vrae na aanleiding daarvan korrek beantwoord
Ek kon gegewe koördinate op ’n kaart korrek interpreteer en die opdragte by 16.2 korrek uitvoer
Ek kon die vrae na aanleiding van die kombinasie van koördinate en rigting korrek beantwoord (17.2)

Leeruitkomste 1: Die leerder is in staat om getalle en die verwantskappe daarvan te herken, te beskryf en voor te stel, en om tydens probleemoplossing bevoeg en met selfvertroue te tel, te skat, te bereken en te kontroleer.

Assesseringstandaard 1.8: Dit is duidelik wanneer die leerder hoofrekenberekeninge doen wat kwadrate van natuurlike getalle tot minstens 10 2 en derdemagswaardes van natuurlike getalle tot minstens 5 ³ behels.

Leeruitkomste 3: Die leerder is in staat om eienskappe van en verwantskappe tussen twee-dimensionele vorms en drie-dimensionele voorwerpe in ‘n verskeidenheid oriëntasies en posisies te beskryf en voor te stel.

Assesseringstandaard 3.8: Dit is duidelik wanneer die leerder posisie/ligging op koördinaatstelsels (geordende roosters) en kaarte bepaal.

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 variasie te interpreteer en te bepaal.

Assesseringstandaard 5.9: Dit is duidelik wanneer die leerder data wat op verskeie maniere voorgestel is krities lees en interpreteer ten einde gevolgtrekkings en voorspellings te maak wat sensitief is.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
