Besparing van energie

Opvoeders afdeling

Memorandum

Uit huis: Enige voorstelle. Meestes kom op insulasiemeganismes neer.

Rem: kry rem los. Papwiel: pomp die band.

Idees:

Daar is baie. Gee leerders voldoende geleentheid en laat gesprek toe.

Inhoud

Aktiwiteit: om te kan beskryf hoe energieverlies beperk kan word [lu 3.2]

Kyk weer na die illustrasie van die huis by Aktiwiteit 4.1. Gesels in 'n groepie en dink aan maniere waarop julle die energieverlies uit die huis sou kan verminder:

1. ___________________________________________________________________

2. ___________________________________________________________________

3. ___________________________________________________________________

4. ___________________________________________________________________

5. ___________________________________________________________________

X Gevolgtrekking 1: energieverlies kan verminder word deur goeie isolasie .

Dink aan die voorbeelde met die remme en die papwiel in Aktiwiteit 4.1. Hoe kan die verlies van energie in die twee gevalle verminder word?

_____________________________________________________________________

  • Gevolgtrekking 2: energieverlies kan verminder word deur toe te sien dat sisteme goed funksioneer.
  • Gevolgtrekking 3: ons het ook gesien dat energie bespaar kan word deur die korrekte gebruik van elektriese toestelle.

Hier is 'n paar maniere om elektrisiteit in die huis te bespaar.

  • Skakel die warmwatersilinder af as julle langer as ‘n week van die huis gaan weg wees.
  • Kook water in ‘n ketel en gooi dit dan in ‘n warmfles om later te gebruik.
  • Dit is onnodig om elke keer ‘n vol ketel water te kook as jy net een of twee koppies vol nodig het.
  • Gebruik lae-energie gloeilampe.
  • Installeer sonpanele op die huis se dak.

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
