Cluster sampling refers to a sampling method that has the following properties. The population is divided into N groups, called clusters.
Identify characteristics of the four main groupings of stars on the diagram. The H-R Diagram shows the similarities among stars in the sky. The diagram is used for understanding the life cycle of the stars.
The diagram effectively classifies or categorizes the stars by certain characteristics. The characteristics include luminosity, spectral type, color, temperature, and evolutionary stage. In your answer, include interstellar medium, protostar, and how stellar equilibrium is finally reached.
A star is born after it is formed from the condensation of a hot cloud of gas and dust in space. The cloud gets very hot and dense and this inspires fusion to occur fusion is the combination of hydrogen atoms into helium atoms. It depends on the size of the cloud as to whether one star, a binary star, or a cluster of stars is formed.
Once a star's hydrogen starts to deplete, it begins to die. In other words, a star can only last as long as it has hydrogen to fuel it. The star is in the last stages of life once its hydrogen starts to run low. The next stage is different for every star depending on its size.
For example, an average-sized star such as the sun, will spend its last time in life as a red giant.
The star will look reddish in color and it will grow larger than its original size. The sun, which is average in size, will effectively "bloat" in size. Once it is a red giant, it blows off its gases and then it will eventually simply collapse.
The star, our sun, will then fade and turn into a white dwarf, the inner core of the star. The white dwarf will eventually cool down and turn into a black dwarf, giving off no light or heat. However, because the cooling off process takes so long, it is believed that no star has ever reached this phase in its life cycle.
A red dwarf or a smaller mass star dies in the same way as an average-sized star like our sun, except that it does not turn into a red giant and it takes billions of years more to turn into a white dwarf and then a black dwarf.
A very large star -- a blue giant -- dies like other stars, or else it can go supernova. When a blue giant is dying, it gets very hot and bright and turns into a super giant.
It then collapses -- but its collapse is inward -- as it explodes.The visual cluster diagram is a graphic organizer that writers use to prepare any type of writing--essays, research, reports, scientific or business writing, stories, and presentations.
The cluster allows for writers to visualize their thinking by grouping ideas in a visual manner. Sequence, Cycle, Timeline, Cluster, Hierarchy, and Chain of Events Graphic Organizers (11 Organizers).

Help your students children classify ideas and communicate more effectively. Use graphic organizers to structure writing projects, to help in problem solving, decision making, studying, planning research and brainstorming.
A concept map is used to organize these ideas into a coherent structure so that a plan can be devised. Microsoft Word is a word processing program that has the ability to draw shapes. These shapes can be linked to create a concept map.
