FRIDAY, SEPTEMBER 25, 2009

Today was a very fun day.

We learned how you can see the rainbow in the visible spectrum coming off of other light emitting objects. Using the tools Dr. Bautista gave us, we would look at the light and the different elements she put up on her desk. We saw that different elements emitted different colors of the rainbow in the spectrum. This is because when you send energy through the element tube, the electrons in the element get excited. When they get excited, they jump from one energy level to the other. That jump emitts light. Depending on how far and from what enery levels the electrons come from and go to, different colors of the rainbow will be seen.

We also played with fire which i thought was the coolest part of the whole day. When you spray borax on a big open flame and a candle, the flame changes from its original color to green. When you spray stronium nitrate into a big open flame and a candle, the flame changes from its original color to a bright red. We also saw that when you spray these two chemicals in an big open flame and a candle, the flame from the candle is a whole lot bigger than the one emitted by the big open flame.

This pretty much wraps up what we did in class on Friday.

P.S. Dr. Bautista always said to clean up after you do lab!!!

    That video shows what happens when you light solid strontium nitrate on fire, but it's basically the same as the liquid (don't try it at home). For more useful information, this site has a quick rundown of the electromagnetic spectrum.
