Brass is a buttery yellow alloy of zinc and copper which has been manufactured for thousands of years in many parts of the world.
A teacher is usually issued a contract stating that they work 180 days a year, 7 hours a day (including a 30 minute lunch and 30 minute break) BUT almost any good teacher puts â¦ in an additional 2-4 hours daily plus several hours at home for FREE just striving for students success.
Teaching is typically a full-time job. School hours are non-negotiable; a teacher must be there when the students are. However most schools are only in session for six or seven hours a day and teachers can spend the additional hour or two of grading papers and preparing lesson plans whenever they choose.
