Module 16

'n gebalanseerde dieet

Aktiwiteit:

Om 'n gebalanseerde dieet te beskryf

[lo 1.3]

Dink gou: wat het jy gisteraand geëet? En vanoggend voor skool?

Kos word in voedselgroepe opgedeel. ‘n Mens moet elke dag iets van elke voedselgroep eet om ‘n gesonde dieet te volg.

Alle lewende wesens het voedsel nodig vir energie, om te beweeg, om te groei en om selle te herstel wat beskadig is. Hulle het ook spysverteringstelsels om die voedingstowwe wat die liggaam nodig het, uit die voedsel te haal terwyl ons eet.

Voedselgroepe:

Proteïne help ons om nuwe selle te vervaardig en sterk en gesond op te groei.

Bronne van proteïne : vleis, vis, kaas, eiers, melk, sojaboontjies, neute

Vitamines hou ons gesond en maak ons bene en tande sterk.

Bronne van vitamines : vrugte en groente, lewer, melk, olierige vis.

Vette verskaf energie. Energie word in vette in die liggaam gestoor totdat dit benodig word.

Bronne van vette : botter, melk, kaas, neute, room, sardientjies, margarien, olie.

Suiker en stysel (koolhidrate) verskaf ook energie aan die liggaam.

Bronne van stysel en suiker : vrugte, koekies, lekkers, brood, gewone suiker, aartappels, rys.

Minerale : kalsium bou sterk bene, tande en spiere / yster help rooibloedselle om suurstof van die longe na die res van die liggaam te vervoer

Bronne van minerale : melk, kaas vis, groente, vrugte, lewer, witbrood

Opdrag:

In hierdie module sal jy die ontvouing van ‘n kubus vind. Teken die bronne aan wat aangedui word, met hul opskrifte op die vlakke van die kubus. Knip en vou dit dan soos aangedui en hang dit in die klas op.

Werk nou ‘n gebalanseerde spyskaart vir een dag uit, met drie etes ingesluit.

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   ondersoek beplan;

1.2   ondersoek uitvoer en data versamel;

1.3       data evalueer en bevindings kommunikeer.

 

Memorandum

Opdrag met kubusse: Gebruik die aangehegte kubusvorm en laat die kinders mooi netjies daarop teken en in die klas ophang.

Stapelvoedsel:

  • Suid-Afrika: brood
  • Italië: spaghetti
  • Ierland: aartappels
  • China: rys

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,
