Different elements have different energy levels, so give off different colored packets of lights to make their own unique spectra. To move an electron from a lower to a higher energy level, you heat the element (flame from Bunsen burner).
4. Look at the following website: http://www.colorado.edu/physics/2000/quantumzone/bohr.html Go over the most important pieces: the applet showing how electrons jump from one energy level to another, and the Dave’s Whizzy Periodic Table that show the shell and nuclear view of elements from the periodic table as well as the associated spectrum. You can also show this website to compare spectra: http://members.misty.com/don/spectra.html
5. Return to Penny Lab: Could you make gold if you could change the electrons? If you could change the neutrons? If you could change the protons? CAN we even do this stuff? Think-Pair-Share. Discuss.
