Inhoud

Aktiwiteit: om twee-dimensionele vorms en drie-dimensionele voorwerpe te skat, te meet en aan te teken [lu 4.4.3]

Om gebruik te maak van toepaslike meetinstrumente [lu 4.6.3]

Jy weet nou al uit die werk wat ons in graad 4 en 5 afgehandel het dat ons altyd in eenhede meet.

1. Kyk goed na die volgende en voltooi dan die tabel:

  • Sê in watter eenheid sal jy die volgende meet.
  • Skat die lengte.
  • Meet dan die ware lengte.
Eenheid Skatting Werklike lengte
Lengte van jou bank ______________ ______________ ______________
Jou eie lengte ______________ ______________ ______________
Breedte van klas ______________ ______________ ______________
Dikte van skryfblok ______________ ______________ ______________
Lengte van potlood ______________ ______________ ______________

2. In watter eenheid sal jy die afstand tussen jou huis en die skool meet?

_____________________________________________________________________

3. Kom ons toets jou geheue! Kyk of jy die volgende vrae kan beantwoord:

3.1 Hoeveel meter is daar in 1 kilometer?____________________________

3.2 Hoeveel millimeter is daar in 1 meter? ___________________________

3.3 Hoeveel sentimeter is daar in 1 meter?___________________________

3.4 Hoeveel millimeter is daar in 1 sentimeter?_______________________

ONTHOU JY NOG?

Die volgende behoort jy reeds te ken, maar kom ons kyk weer daarna:

km m cm mm

Assessering

Leeruitkomste 4: Die leerder is in staat om gepaste meeteenhede, instrumente en formules in ‘n verskeidenheid kontekste te gebruik.

Assesseringstandaard 4.4: Dit is duidelik wanneer die leerder twee-dimensionele en drie-dimensionele voorwerpe skat, meet, aantekeninge maak van, vergelyk en orden deur S.I.-eenhede met die geskikte noukeurigheid te gebruik vir:

4.4.3: lengte m.b.v. millimeter (mm), sentimeter (cm), meter (m) en kilometer (km);

Assesseringstandaard 4.6: Dit is duidelik wanneer die leerder gepaste meetinstrumente gebruik (met ‘n begrip vir die beperkings daarvan) tot op geskikte vlakke van noukeurigheid, insluitend:

4.6.3: liniale, meterstokke, maatbande en klikwiele om lengte te meet.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
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.
Tarell
what is the actual application of fullerenes nowadays?
Damian
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.

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.
