Inhoud

Aktiwiteit: om die begrip konstellasies te kan bespreek en die beweging van sterre te ondersoek [lu 1.2, lu 2.3]

In antieke tye het sterrekundiges helder sterre in groepe wat patrone gevorm het, groepeer. Hierdie patrone word konstellasies genoem en is na mense, gode en diere vernoem. Elke konstellasie het ‘n Latynse naam. As gevolg van die omwenteling van die aarde om die son, verskyn verskillende konstellasies, verdwyn dan, en verskyn weer later gedurende die loop van ‘n jaar.

  • Daar bestaan “sterkaarte” vir die Noordelike, sowel as die Suidelike Halfrond. Konstellasies word verskillend op verskillende “sterkaarte” aangedui. Ons hoef ons egter nie daaroor te bekommer nie, want daar is nie ‘n “korrekte” manier om konstellasies te teken nie.

Die konstellasies van die suidelike halfrond

Beweging van sterre en konstellasies

  • As jy vir die eerste keer buitentoe gaan om na die konstellasies te kyk, mag dit vir jou onmoontlik lyk om enige konstellasie tussen die massa sterre in die hemelruim op te spoor. As jy egter een keer ‘n konstellasie gevind het, sal jy dit die volgende keer baie maklik opspoor.
  • Een van die dinge wat dit moeilik maak om sterre op te spoor is die feit dat die sterre die heeltyd “beweeg”. Hulle behou hul posisie ten opsigte van mekaar, maar hulle verskyn elke aand en hulle beweeg deur die lug gedurende die nag.
  • Sommige sterre skyn heelnag, terwyl ander verdwyn en nuwes hul plekke inneem. Hierdie beweging vind baie stadig plaas en jy sal dit nie opmerk as jy net na die sterre staan en kyk nie.

‘n Eksperiment om vas te stel of sterre beweeg

1. Kies ‘n helder ster of konstellasie, bv. die Suiderkruis, en staan êrens sodat die ster/konstellasie presies bokant ‘n vaste baken (bv. ‘n boom of die dak van ‘n huis) is.

2. Teken die tyd aan en keer een uur later na die PRESIESE posisie terug.

Het die ster/konstellasie beweeg?_________________________

Indien wel, in watter rigting (wes, noord, oos of suid)? ______________________

Het die ster/konstellasie se posisie t.o.v. ander sterre verander?

_____________________________________________________________________

3. Bestudeer die posisie van jou ster/konstellasie vir ‘n paar agtereenvolgende aande en teken telkens die presiese tyd aan wanneer dit jou baken bereik.

how did psychology begin?
Valerie Reply
of psychologys commencement, the traces can be seen in the work of Aristotle, where he talk about soul and body, likewise work in durrant, de anima, all these were somewhere supporting dualism, in which soul could exist separately from body
amaan

hae everyone, hope you are well this evning my question is what is the difference between drive and motivation
Michael
good question
Rainee
drive is more like an impulse or urge and i think they both go together (drive and motivation) even if there is a slight difference
edem
@ Michael Drive is delivered to be innate without the use of an external stimuli, motivation normally evolves an outside stimuli which may include praise, appreciate, or reward.

the biggest problem with scientific research and data is that ya you could get the same result 1000 times then it could go the other way 1000 times, but we would never know that and we did, we would still say ya but the proof is there. The only thing science proves is that humanity has

Anyone knows about Techno-fascism?
Hussein Reply
Ecofascism is a theoretical political model in which an authoritarian government would require individuals to sacrifice their own interests to the "organic whole of nature". The term is also used as a rhetorical pejorative to undermine the environmental movement.

what's the big difference between prejudice and discrimination?
Danice Reply
A prejudiced person may not act on their attitude.  Therefore, someone can be prejudiced towards a certain group but not discriminate against them.  Also, prejudice includes all three components of an attitude (affective, behavioral and cognitive), whereas discrimination just involves behavior
