Extract of sample "North Circumpolar Motion of Stars"

North Circumpolar Motion of Stars ment of purpose This experiment seeks to relay adequate and clear understanding of how stars close to the northern pole usually move. This is by observing certain set of stars, which are seven in number of the famed Big Dipper within a given number of hours as per the experiment.
Procedure
Initial experiment encompassed choosing an appropriate location just after sunset meant to observing the stars, which is facing the Northern region.
The right location was to be devoid of any obstructions such that the view of Dipper was quite visible, then facing to the North on the horizon.
Observations in this case encompassed making outcomes from the northern sky after every 90 minutes coupled with tabulating the intended results. Observations involved here were three sets.
For each task of observing, recording and sketching of Big Dipper’s location in relation to polar is, Horizon and zenith were made in a sketch (Seeds & Dana 17). This was with keenness to avoid poor observation as indicated by Figure 2.
Polar is in this experiment was used as the fixed star whereby it was supposed to be in front in the horizon.
After setting up the entire experiment and choosing the right location, the starts were observed in the intervals of 90 or 120 minutes then observations regarding the change of locations recorded. These alterations in locations were in relation to polar is and horizon.
Data and Calculations
Zenith
Polaris
Horizon
West North East
Correct orientations!!!
Figure 1
Zenith
Polaris
Horizon
West North East
Incorrect Orientation !!!
Figure 2
Conclusions and analysis
From the observations, it was ascertained individual stars in relation to both horizon and Polar showed significant relocations in the Northern sky. However, the main error associated with not obtaining exact data as predicted was incorrect orientation was among them as indicated in Figure 2.

Visual Rock Music Stars

...Visual Rock Music Stars Dress and Ideology Introduction For the project I have chosen to examine the relationship between dress and ideology of visual rock music stars. This group was chosen as the visual nature of the group allows for a thorough analysis of the ways in which the beliefs of the group may affect their decisions relating to dress. In order to gain information, an interview will be conducted with members of a rock music group with which I am familiar. This interview will be used to ascertain the history of the group and the beliefs of the group. The interview will also obtain information about how the group's beliefs have changed over time. The information from the interview will be used alongside photographs of the group...

Visual Rock Music Stars

... VISUAL ROCK MUSIC STARS DRESS AND IDIOLOGY DEPARTMENT: PLACE: DECEMBER, 2007 Visual Rock Music Stars Dress and Ideology It can be said that 1950s were the times of overwhelming boredom for young people as well as remarkable excitement, dominated by imperious pressures toward traditionalism and accord. According to the studies of professor Richard Aquila (1992: 269-270) these two domineering forces were ruling the decade, reducing the opportunities for being diverse and, thus, downgrading the expressions of new opinions and ideas of the society. It was clear that time for rebellious changes had come, thus a new style in music appeared. The style that brought about change and uproar, with unusual hairstyles, provocative clothing...

Life Cycle of Stars

...Life Cycle of Stars The shining twinkle-twinkle little or big stars are all composed of enormous clouds of dust and gas. Stars too have a life of their own. These formations appear as twinkling to us because they are at a far off place from our earth and the atmospheric conditions, diffractions etc. lead to the phenomenon of twinkling. Light is actually an electromagnetic wave that can be 'seen' by us. Initially there was much discussion over whether light is composed of particles or waves. Subsequent experiment proved that Light displays a dual nature1. While on the one hand particles are supposed to have some mass which can respond to forces (acceleration) waves can transfer energy from one place to another. The Corpuscular theory...

Child Stars

... Child Stars Ignoring mental illness or the typical “they just snapped,” how can we explaintheir behaviors? Child stars have been known to shine and lovable in the beginning of their career but a few years down the line they acquire a different look and become the topic of gossip as they make a 180 degrees transformation to the opposite of what they were. This is a common scenario with almost 80% of the child stars not only in the United States but in the world as well. The most common of these child stars is Britney Spears and the latest of them is Miley Cyrus. There are several explanations for their transformations and a concrete explanation of their behavior which should not just be taken at face value. The stigma management theory...

Keystone species - Sea stars

... competition for resources or through predation. The sea stars are considered a keystone species in the rocky intertidal habitat because it determines the habitat’s composition. One of its significant effects is its control over the population of mussel. It dictates the population of mussels within the intertidal region that it inhabits. Even though it can predate many other invertebrates in the middle intertidal, its preference of mussels determines the prey’s population in the habitat. This has secondary effects on populations of other species in the middle intertidal. In the absence of sea stars, mussels grow and colonize the middle intertidal. This leads to extinction of other species such as barnacles and large algae in the locality...

White Dwarf Stars

... White Dwarf Stars Introduction Mostly these are burn out cores of exhausted stars commonly the size of a planet. Exhaustion in this case implies depletion of both their inner/central nuclear fuel and outer layers of low-dense nebula bodies before eventually collapsing to form a dense mass (“NMSU”). The formed dense mass does not have any empty space in between atoms of the collapsed stars. These stars are normally white in color as the name suggest and occupy the lowest region in the HRD diagram due to their quality or composition. Hence, they are in comparable to sun, giant stars whose location are in main sequence and giantes’ positions respectively. Mainly, white dwarfs’ string stretches through K-dwarf temperature region...
