Week 18, Day 3: Lab Again-I see the light...or at least spectral bands.
The photo below left shows students looking through the spectroscope tubes at the glowing gas tube (it's like a mini fluorescent light). We actually do this in the dark. I don't use the tubes anymore. We just pull the ends off and hold them up like a fancy monocle (I spent 12 years fighting the long tube and could not see easily and it was fixed by just using the end cap with the specturm film).
I hope this helps.
Love to teach and teach with passion.
Remember, It's not magic, It's Science!
