Bone

A bone is a rigid organ that constitutes part of the vertebral skeleton. Bones support and protect the various organs of the body, produce red and white blood cells, store minerals and also enable mobility. Bone tissue is a type of dense connective tissue. Bones come in a variety of shapes and sizes and have a complex internal and external structure. They are lightweight yet strong and hard, and serve multiple functions. Mineralized osseous tissue, or bone tissue, is of two types, cortical and cancellous, and gives a bone rigidity and a coral-like three-dimensional internal structure. Other types of tissue found in bones include marrow, endosteum, periosteum, nerves, blood vessels and cartilage.

Bone is an active tissue composed of different types of bone cells. Osteoblasts are involved in the creation and mineralisation of bone; osteocytes and osteoclasts are involved in the reabsorption of bone tissue. The mineralised matrix of bone tissue has an organic component mainly of collagen and an inorganic component of bone mineral made up of various salts.

High school

A high school (also secondary school, senior school, secondary college) is a school that provides adolescents with part or all of their secondary education. It may come after primary school or middle school and be followed by higher education or vocational training.

Terminology

The term "high school" originated in Scotland, with the world's oldest high school being Edinburgh's Royal High School from 1505. The Royal High School was used as a model for the first public high school in the United States, Boston Latin School founded in Boston, Massachusetts.

The precise stage of schooling provided by a high school differs from country to country, and may vary within the same jurisdiction. In all of New Zealand and Malaysia, along with most of Britain and parts of Australia, Bangladesh and Canada, high school means the same thing as secondary school, but instead of starting in 9th grade, these "secondary schools" begin at ages 11 or 12.

Country by country

Australia

In Australia, high school is a secondary school, from Year 7 or Year 8 through to Year 12, varying from state to state. High school immediately follows primary (elementary) school; therefore, a Year-7 Australian high-school student is sometimes as young as 12. In Tasmania and the Australian Capital Territory, the term "high school" generally refers to Years 7–10, whereas the term "College" is used for Years 11–12. In Victoria the term "secondary college" has largely replaced the term "high school" following the reforms of the Labor Government in the late 1980s and early 1990s. Some schools have retained the name "high school" (such as Melbourne High School) and many have now dropped the "secondary" and are simply known as "college".

Marching band

A marching band is a group in which instrumental musicians perform for entertainment, and prepare for a competition. Instrumentation typically includes brass, woodwinds, and percussion instruments. Most marching bands wear some kind of uniform (often of a military style) that includes the school or organization's name or symbol.

Marching bands are generally categorized by function, size, age, gender, instruments and by the style of show they perform. In addition to traditional parade performances, many marching bands also perform field shows at special events like competitions. Increasingly, marching bands perform indoor concerts that implement many songs, traditions, and flair from outside performances.

History

Band is a general term for an instrumental group. The marching band originated with traveling musicians who performed together at festivals and celebrations throughout the ancient world. It evolved and became more structured within the armies of early city-states, becoming the basis for the military band, from which the modern marching band emerged. As musicians became less important in directing the movement of troops on the battlefield, the bands moved into increasingly ceremonial roles. This intermediate stage led to the modern instrumentation and music for marching bands. Many military traditions survive in modern marching band. Bands that march in formation are often ordered to "dress their ranks" and "cover down your file." They may be called to "attention," and given orders such as "about face" and "forward march." Uniforms of many marching bands still resemble military uniforms.
