This involves a series of demonstrations with adapted POGIL models. I show the emission lines of 8 different bulbs ( hydrogen, helium, oxygen, neon, argon, nitrogen, mercury, white light). Students look at the bulbs through diffraction glasses then draw the emission lines that they see. *** note the room will need to be VERY dark. I also show the educational innovation glowing ball demonstration and how light diffracts off of a cd/dvd. Then students work through models showing energy of electron
