Honors chemistry students in Dr. Dinkins’s first period conduct flame tests to study light emission from elements after electrons absorb and release energy. In this video, students are observing the crimson color produced by strontium ions. Students collect data to later identify unknowns and relate the colors seen to the movement of electrons between energy levels in atoms. The phenomenon observed is directly related to how fireworks produced their array of colors.
