Curated OER
Find the Mystery Lines...If You Can!
In this atomic spectral lines worksheet, students observe a diagram of the spectral lines, their different wavelengths and their intensity. They solve 4 problems which include interpreting the scale, matching up tabulated lines with the...
Curated OER
Atomic Emission Spectra and the Bohr Model of the Atom
High schoolers investigate the wavelengths of spectra lines for common atoms. In this atomic emission spectra lesson plan, students use a transformer and diffraction grating to observe the emission spectra of various atoms. They find the...
