Content

Activity: to discuss the concept constellations and investigating the movement of the stars [lo 1.2, lo 2.3]

IN ANCIENT TIMES ASTRONOMERS GROUPED BRIGHT STARS THAT APPEARED TO FORM SOME KIND OF PATTERN. THESE IDENTIFIABLE PATTERNS ARE CALLED CONSTELLATIONS AND ARE NAMED AFTER PEOPLE, GODS AND ANIMALS. EACH CONSTELLATION BEARS A LATIN NAME. THE ORBIT OF THE EARTH AROUND THE SUN HAS THE EFFECT THAT SOME CONSTELLATIONS COME INTO VIEW, DISAPPEAR FROM OUR VIEW AT CERTAIN TIMES AND APPEAR AGAIN LATER DURING THE YEAR.

  • Maps of the heavens that indicate the positions of the stars have been drawn for the Northern as well as the Southern Hemisphere. But there is no fixed way to draw the constellations and different "star charts" may show them differently.

THE CONSTELLATIONS OF THE SOUTHERN HEMISPHERE

THE MOVEMENT OF THE STARS AND THE CONSTELLATIONS

  • When you go out to look at constellations for the first time, it may seem impossible to detect any of them among the dense array of stars in the heavens. But once you have located a constellation, you will be able to find it easily when you try again.
  • What makes it difficult to identify a constellation is the constant movement of the stars. They keep their positions with regard to each other, but they rise every evening and travel through the sky during the night.
  • Some stars remain visible right through the night, but others disappear and new stars take their place. The movement is extremely slow and you will not notice it while you are simply looking up at the sky.

AN EXPERIMENT TO DETERMINE WHETHER THE STARS DO MOVE

1. Select a bright star or constellation and stand at an appropriate spot so that the star/constellation is directly above some fixed beacon (e.g. a tree or the roof of a house).

2. Note down what the time is and return to the EXACT spot one hour later.

Can you see whether the star/constellation has moved?_________________________

If so, in which direction (west, north, east or south)? ___________________________

Has the position of the star/constellation shifted with regard to other stars?

_____________________________________________________________________

3. Study the position of your star/constellation over a number of consecutive evenings and record the precise time when it reaches your chosen beacon.

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,

what is cell division
Aron Reply
Cell division is the process by which a single cell divides into two or more daughter cells. It is a fundamental process in all living organisms and is essential for growth, development, and reproduction. Cell division can occur through either mitosis or meiosis.
