Hulpbronne en dienste in ‘n nedersetting

Module 14

Water in ons huise

Water as hulpbron

Sonder water is lewe op aarde nie moontlik nie. Water is ook die bestanddeel wat die meeste op die aarde voorkom – dit bedek ongeveer 80 % van ons planeet se oppervlakte. Van hierdie 80 % is slegs 3 % varswater, en die meeste van hierdie varswater kom voor in ysvorm, naamlik in die ysvelde by die Noord- en Suidpool.

‘n paar interessante feite:

  • Tussen 60% en 70% van jou liggaam bestaan uit water.
  • 85% van jou brein is water.
  • 25% van jou gebeente is water.
  • 83% van jou bloed is water.
  • ‘n Mens kan langer as twee weke sonder kos oorleef, maar slegs drie dae sonder water.
  • ‘n Mens verloor gemiddeld 2,5 liter water per dag weens sweet, uitaseming en afval.

1.water in ons huise

Noudat julle kennis gemaak het met al die interessante gegewens oor die mens en water, is julle oortuig daarvan dat water die heel belangrikste hulpbron is? Hou gerus ‘n klasbespreking daaroor.

Waarvoor het julle gesin water nodig? gesels met jou maat daaroor en vul die lysie in die blok hieronder met julle eie antwoorde aan.

Aktiwiteit 1

Om oor die gebruike van water in en om die huis te gesels [lu 2.2]

Water vir ons huisgesin

2.waar kom julle water vandaan?

Wanneer dit reën, vloei die water in riviere en strome en uiteindelik beland dit in groot damme wat in die riviere gebou is. Dit word opgaardamme genoem. Van die opgaardamme word dit met groot pype na waterwerke vervoer waar die nodige suiwering van die water plaasvind. Hierna word dit met kleiner pypleidings na die dorpe en stede en uiteindelik ons eie huise vervoer. Vind uit watter opgaardam(-me) naaste aan julle is. Skryf die dam(-me) se naam/name hier neer:

Aktiwiteit 2

Om die faktore te identifiseer wat veroorsaak dat sommige mense beter toegang tot skoon water het as ander [lu3.2]

3.toegang tot water

  • Ons regering bestee baie geld om vir al die mense in ons land skoon water vir drink- en huishoudelike gebruik te voorsien. Die ideaal is dat elke huishouding lopende water wat skoon en veilig is, in die huis moet hê.
  • Daar is egter nog baie mense wat ver moet loop om hulle water in houers te gaan haal en huis toe te dra. Dikwels skep hulle die water uit riviere wat besoedel word deur mense, diere en fabrieke. Die besoedelde water veroorsaak siektes waaraan mense kan sterf.
  • Informele nedersettings ontstaan en groei soms so vinnig dat plaaslike regerings nie betyds lopende water kan aanlê nie. Die mense bou hulle skuilings naby oop waterbronne soos riviere. Almal gebruik dan dieselfde bron. Mense skep hulle drinkwater daaruit, maar was ook hulself en hulle wasgoed daarin. Kinders speel of swem daarin en diere mors daarin. Daar word ook dikwels afvalwater uit fabrieke in die riviere gestort.
