Let us look at an actual episode of culturally responsive teaching based on this motivational framework.

From Wikipedia, the free encyclopedia. Secondary air injection (commonly known as air injection, or colloquially smog pump or pollution pump) is a vehicle emissions control strategy introduced in 1966, wherein fresh air is injected into the exhaust stream to allow for a fuller combustion of exhaust gases.

An air ioniser (or negative ion generator or Chizhevsky's chandelier) is a device that uses high voltage to ionise (electrically charge) air molecules.Negative ions, or anions, are particles with one or more extra electrons, conferring a net negative charge to the particle.ost commercial air purifiers are designed to generate negative ions. Another type of air ioniser is the ESD ioniser (balanced ion generator) used to neutralise static charge. In 2002, Cecil Alfred 'Coppy' Laws was credited with being the inventor of the domestic air ioniser in an obituary in The Independent newspaper.
