Interafhanklikheid van grond, plante en diere

Aktiwiteit:

On die interafhanklikheid van grond, plante en diere te beskryf

[lu 1.1, 1.3]

Plante en diere is afhanklik van mekaar en van die omgewing waarin hulle leef.

Kyk na die volgende voorbeeld van ‘n tipiese voedselketting (begin onder):

  1. Skryf in jou eie woorde hoekom grond belangrik is vir plante.
  1. Diere is baie afhanklik van plante. Hoekom?

Daar is egter ook plante wat giftig is vir die mens of ander diere.

Gevaarlike of giftige plantsoorte

Diere en mense kan geaffekteer word deur giftige plantsoorte wat dalk in weivelde voorkom. Giftige plante kan selfs die dood veroorsaak.

Navorsing

Soek en gee mondelinge terugvoering in groepies van ± vier oor die volgende. Inligting kan in ‘n biblioteek, op die internet of van jou opvoeder verkry word.

  1. Die naam van een plantsoort wat giftig is vir die mens.
  1. Beskryf moontlike simptome van vergiftiging.
  1. Hoe moet so ‘n pasiënt teen die vergiftiging behandel word?

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 duidelik wanneer die leerder:

1.1   ondersoeke beplan;

1.2   ondersoeke uitvoer en data versamel;

1.3       data evalueer en bevindinge kommunikeer;

 

Memorandum

  • Grond is belangrik omdat plante daarin groei.
  • Plante dien as voedsel vir die diere
  • Giftige paddastoele
  • Gewoonlik naarheid, opgooi en maagwerkings.
  • Die maag moet uitgepomp word.

lack electricity and its more savely than electronic microscope because its naturally by using of light
Abdullahi Reply
advantage of electronic microscope is easily and clearly while disadvantage is dangerous because its electronic. advantage of light microscope is savely and naturally by sun while disadvantage is not easily,means its not sharp and not clear

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,
