This quarter the Juniors in High School Chemistry class were studying atoms and their electron shells and how they emit light at different frequencies depending upon the elements involved when they are excited (energized). To do this they conducted a Flame Test Lab to demonstrate the variety of colors produced when different metals or salts meet a flame. It contributed to their understanding of:
- Energy
- Electromagnetic Spectrum
- Atomic structure
- Atomic spectra
- Electrons
- Visible light spectrum
By the end of the lesson and the lab the students were able to:
- Use flame tests to identify a metal or metallic salt by the color that it produces when it is put in a flame.
- Calculate the frequency of the light given its wavelength
- Calculate the wavelength given its frequency
- Identify an unknown metal by the color it emits.
