Go to the neon discharge tube lab at PHET. Use it to answer the following questions.
1. Gather evidence to prove that different elements have unique characteristics (hint: use a PrtSc button and paste into a Word document)
2. Explain, step-by-step, how a single electron is excited by a discharge lamp
3. Compare step-by-step emission to a continuous stream emission.
4. Using JUST the applet, not a google search, how do you think fluorescent light bulbs work? (hint: do all line spectra need to be visible?)
Be ready to hand this in tomorrow.
==============Poster
Create a poster that talks about emission and absorption spectra, and details how they can shift due to rotation, red shift, or blue shift. use your book to do this.
