The bus company that your school uses is thinking about changing the material that
makes their current fleet of buses because the buses are running into problems with
corrosion, the reaction of metals with oxygen present in air to form metal oxides that
are not structurally sound and are visually unappealing. In addition, the current
construction material is difficult to shape and is not visually attractive. The bus
company has asked your teacher to recommend an alternative material that could be
used to manufacture the next round of buses needed for your school and other schools
in the district. In addition to meeting certain chemical and physical requirements, the
material recommended must also be affordable.
