Module 37

Ekotoerisme

Aktiwiteit:

Om die waarde van ekotoerisme te kan verduidelik en ’n produk te ontwikkel wat gebruik kan word om ander te inspireer

[lu 1.1; 1.2; 1.3; 3.2]

Ekotoerisme verwys na ’n industrie wat toeriste aanmoedig om die land se natuur­skoon en ekologies ongerepte dele te beleef en te waardeer.

Suid-Afrika is die enigste land op aarde waarin al die lede van ’n bepaalde plant­koninkryk natuurlik binne sy grense aangetref word. Die plantkoninkryk waarna ons verwys, is die FYNBOS in die Wes-Kaap.

Dit is ’n area wat strek rondom die Bolandse berge en wat verskeie unieke plant­soorte soos die protea (ons nasionale blom) en heide insluit. Dit is die grootste konsentrasie plantspesies ter wêreld wat endemies is. Endemies beteken dit kom nêrens anders natuurlik voor nie.

St. Lucia en ander vleilande is weer ons geboorteplekke van baie spesies. Dit is in fyn balans en kan maklik versteur word deur 4x4-entoesiaste, asook plesier­boot­avonturiers.

Daar is gedurig nuusartikels oor hierdie en ander sensitiewe areas en onsensitie­we mense wat nie weet hoe om dit te benut, te waardeer en te bewaar nie.

Ons wildparke soos die Krugerwildtuin, die Kgalagadi, Hluhluwe en Pilanesberg is wydbekend by oorsese toeriste.

NATUURBEWARING is in al hierdie areas van die grootste belang en streng reëls geld wat wel deur die bedagsames onder ons nagekom word.

Ontwerp ’n kleurvolle brosjure wat jy aan ’n oorsese toeris sou kon gee om die natuurskoon van Suid-Afrika, asook sy ekologiese juwele, bekend te stel.

  • Jy kan een of meer onderwerpe kies.
  • Dit beteken dat jy die natuurskoon en uniekheid (plante en diere) van ’n bepaalde omgewing en die sensitiwiteit daarvan moet navors en die bevindings in die brosjure inbou.
  • Handig in op die datum wat deur jou onderwyser vasgestel word.

As alternatief : Stel ’n video-insetsel of foto-album saam van so ’n natuurgebied en vertoon dit aan die klas.

Assessering van BROSJURE

Kon jy BEPLAN en FEITE KONDENSEER in ’n visuele voorlegging?

Assessering

LU 1

Wetenskaplike Ondersoek

Die leerder is in staat om met selfvertroue op weetgierigheid oor natuurlike verskynsels te reageer, en om binne die konteks van wetenskap, tegnologie en die omgewing verbande te ondersoek en probleme op te los.

Dit is bewys as die leerder:

1.1 ondersoeke kan beplan;

1.2 ondersoeke kan uitvoer en data kan insamel;

1.3 data kan evalueer en bevindinge kan kommunikeer.

LU 3

Wetenskap, die Gemeenskap en die Omgewing

Die leerder is in staat om begrip van die onderlinge verband tussen wetenskap en tegnologie, die samelewing en die omgewing te toon.

Dit is bewys as die leerder:

3.1 wetenskap as ‘n menslike aktiwiteit kan verstaan;

3.2 volhoubare gebruik van die aarde se hulpbronne verstaan.

Memorandum

Aktiwiteit: brosjure of video

Leerders ontwerp ’n kleurvolle brosjure wat aan ’n oorsese toeris gegee sou kon word om die natuurskoon van Suid-Afrika asook sy ekologiese juwele bekend te stel. Die leerder kan een of meer onderwerpe kies.

Assesseer saam met paragraaf oor die waarde van ekotoerisme. Let op die volgende:

  • Probleemstelling (beplanning)
  • Bronne wat gebruik is
  • Kwaliteit van inligting (het leerder geselekteer of bloot die eerste en beste vonds gebruik?)
  • Uiteensetting/aanbieding/beredenering (kommunikering)

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.

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
Azam
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.
