Graad 8

Biodiversiteit: aanpassings en oorlewing

Module 30

Volhoubare aktiwiteite

VOLHOUBAARHEID: Wat sê die woordeboek? lewensondersteunend; onbepaald kan aangaan; van " sustenere" – Latyn vir "om van onder af te ondersteun"

Lewe op aarde is net volhoubaar as:

  • die natuur nie deur die gebruik van materiale en die stort van afval beskadig word nie;
  • hulpbronne nie uitgeput word nie;
  • die welsyn van die mens en alle lewende organismes nagestreef word.

Beginsels vir volhoubare ontwikkeling:

  • Beplan behoeftes.
  • Beperk bedreiging van die natuur tot die minimum.
  • Bewaar die natuur vir toekomstige geslagte.
  • Verstaan en betuur menslike bevolkingsgroei.

Aktiwiteit:

Om ‘n klasbespreking te voer oor die volhoubaarheid van hulpbronne

VOLHOUBARE LEWE EN HULPBRONBENUTTING

Sê of die volgende aspekte volhoubaar is al dan nie:

ASPEK JA NEE

1. Sonerenergie-sisteme:

2. Fossielbrandstof:

3. Mynbou:

4. Bosbou:

5. Hidroëlektriese skemas:

6. Kernreaktors:

7. Tot watter slotsom kom jy?

Assessering van KLASBESPREKING OOR HULPBRONNE:

Kon jy die regte afleidings uit die klasbespreking maak?

Assessering

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.

in what situation (s) would be the use of a scanning electron microscope be ideal and why?
Kenna Reply
A scanning electron microscope (SEM) is ideal for situations requiring high-resolution imaging of surfaces. It is commonly used in materials science, biology, and geology to examine the topography and composition of samples at a nanoscale level. SEM is particularly useful for studying fine details,
