Die sterre

Opvoeders afdeling

Memorandum

Opdrag 1:

  • Volg aanwysings in module en laat elke leerder ‘n planisfeer maak.
  • In plaas van die papierknippie kan ‘n drukspyker en Prestik ook gebruik word.
  • Maak seker dat die ure soos volg op die boonste skyf van die planisfeer afgemerk is.

Hoe om die planisfeer “buite” te maak.

1. Hou die kaart omhoog. Dit moet afwaarts wys sodat jy die konstellasies kan sien.

2. Vind die plek op die boonste skyf waar “middernag” aangedui word en maak seker dit wys suid. (Maak seker dat die oostelike en westelike horisonne op die korrekte “plekke” is.)

3. Draai die boonste skyf sodat die presiese uur saamval met die korrekte datum op die onderste skyf.

4. Die sterre wat sigbaar is deur die plastiek, behoort nou sigbaar te wees in die lug bokant jou.

Opdrag 2:

Hierdie aktiwiteit kan in die klas afgehandel word. Om dit eenvoudig te hou, hou die volgende in gedagte

  • 1) verskaf ‘n datum, bv. 26 Mei;
  • 2) en ‘n tyd, bv. 21:00 of 22:00.
  • Hou die tye maar by vol ure en nie ook minute voor of oor nie.
  • Dis belangrik dat die leerders ook moet besef dat sterre ALTYD in die hemelruim is, ook bedags. Ons kan hulle dan egter nie sien nie.
  • Besluit vooraf watter datum aan die leerders gegee gaan word, sodat daar genoeg konstellasies en helder sterre in die ruit van die planisfeer sal verskyn.

Leerder afdeling

Inhoud

Aktiwiteit: om konstellasies en sterre m.b.v. ‘n planisfeer te identifiseer [lu 1.2]

  • ‘n Planisfeer is ‘n model om jou te help om konstellasies in die naghemel op ‘n gegewe tyd te vind en individuele sterre te herken, aangesien alle sterre nie die heeljaar sigbaar is nie.

OPDRAG 1

Maak jou eie planisfeer

1. Teken of fotostateer die volgende vorm op stewige karton en merk die 24 uur van die dag rondom die buiterand.

2. Sny die gedeelte, soos aangedui, uit met ’n skerp messie. Bedek die opening met stewige plastiek soos in die skets aangedui.

3. Fotostateer die volgende sterkaart van die konstellasies in die suidelike halfrond. Knip dit netjies uit op die buiterand en plak op karton.

Belangrik om te weet:

Die name van die helderste sterre word in donkerder letters aangedui.

4. Maak ‘n gaatjie in die middel van albei sirkels en gebruik ‘n skuifspeld om hulle stewig bo-op mekaar vas te maak, soos in die skets.

Gebruik nou die planisfeer soos volg:

Draai die boonste skyf sodat die betrokke tyd ooreenstem met die datum van die betrokke dag op die onderste skyf. Die konstellasies wat sigbaar is deur die plastiekskyf, sal dus ook op dié datum in die naghemel wees.

OPDRAG 2

  • Jou onderwyser sal vir jou ‘n datum en ‘n spesifieke tyd verskaf. Gebruik jou planisfeer en skryf al die konstellasies en helder sterre wat op die gegewe tydstip te sien is, neer. Dui duidelik aan watter konstellasies en watter helder sterre is.

1. Korrekte konstellasies aangedui.
2. Korrekte helder sterre aangedui.
3. Netheid

Assessering

Leeruitkomste 1: Die leerder is in staat om met selfvertroue op weetgierigheid oor natuurlike verskynsels te regeer, en om binne die konteks van wetenskap, tegnologie en die omgewing verbande te ondersoek en probleme op te los.

Assesseringstandaard 1.2: Dis duidelik wanneer die leerder ondersoeke uitvoer en data versamel.

Muhamad Reply
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments

explain assimilatory nitrate reduction
Esinniobiwa Reply
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
