Graad 5


Module 5

Die bepaling van rigting

Aktiwiteit 1

Om noord met behulp van 'n horlosie te bepaal

[lu 1.7]

Die volgende word benodig:

  • ’n Liniaal
  • ’n Potlood

Volg hierdie stappe: (Kyk na die skets)

Stap1 : Staan buite op ‘n sonnige dag. Hou jou horlosie horisontaal (plat) op jou hand.

Stap2 : Hou die stokkie bokant die 12 van die horlosie.

Stap 3 : Draai in die rondte totdat die skaduwee van die stokkie op die 6 tot 12-lyn val.

Stap 4 : Halveer die hoek tussen die uurwyser en die 6 tot 12-skadulyn. Die halveerlyn is noord .

Aktiwiteit 2

Om noord met behulp van die skadustok te bepaal

[lu 1.7]

Verdeel die klas in groepe. Kies ’n sonnige dag. Hierdie metode verg ‘n paar uur, want dit is nodig dat die son na sy hoogste punt styg, en dan weer daal.

Die volgende word benodig:

’n Liniaal

’n Potlood

‘n Groot stuk wit papier

‘n Breinaald of reguit stokkie

Volg hierdie stappe: (Kyk na skets)

Stap1: Plaas die papier op ’n gelyke stuk grond en steek die breinaald deur die middelpunt in die papier.

Stap2: Merk om 10:00 die punt van die skaduwee op die papier.

Stap 3: Merk om 14:00 die punt van die skaduwee op die papier.

Stap 4: Verwyder nou die papier en gaan terug klaskamer toe. Trek nou lyne vanaf die gemerkte skadupunte na die punt waar die naald was (Sien skets ).

Stap 5: Halveer die hoek wat deur ABC gevorm word. Die lyn aan die teenoor­gestelde kant van die skaduwee sal NOORD wees

Aktiwiteit 3

Om uit te vind hoe om in die nag sonder 'n kompas rigting te vind

[lu 1.7]

Doen navorsing om uit te vind hoe jy jouself in die nag sonder ‘n kompas sal oriënteer (met ander woorde, hoe jy noord in die nag sal bepaal).

Skets en skryf jou inligting neer en doen aan die klas verslag oor jou bevindinge.

Soek ten minste twee bronne in die biblioteek wat inligting oor jou onderwerp verskaf.

Lees die eerste bron en skryf die inligting onder BRON 1 in die tabel hieronder neer.

Lees dan die tweede bron en skryf die inligting wat nie in Bron 1 genoem word nie, onder BRON 2 neer.

Maak van albei bronne se inligting gebruik om ’n paragraaf of twee te skryf.


LU 1


Die leerder is in staat om ondersoekvaardighede te gebruik om aardrykskundige en omgewingsbegrippe en -prosesse te ondersoek.

Dit is duidelik wanneer die leerder:

  • bronne met nuttige aardrykskundige inligting kan kies en gebruik;
  • inligting kategoriseer;
  • sketskaarte en/of planne na aanleiding van veldwaarnemings en afmetings teken;
  • ‘n indeks gebruik om plekke op wêreldatlaskaarte te vind;
  • deur projekte, bespreking, debat en diagramme, kennis en begrip van die vraagstuk toon [dra die antwoord oor].

Questions & Answers

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?

algebra 2 Inequalities:If equation 2 = 0 it is an open set?
Kim Reply
or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
Himanshu Reply
good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
Ali Reply
the Beer law works very well for dilute solutions but fails for very high concentrations. why?
