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.

Assessering

LU 1

AARDRYKSKUNDIGE ONDERSOEK

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].

what is the application of nanotechnology?
Stotaw
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
Prasenjit
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
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials

Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
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.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
