Well first of all, a candle contains all colors of the spectra while fluorescent light falls under the unflattering colors like: blues, greens, and violets. It depends on what type of colors different sources adsorb, and this is what produces the colors that we see. The different colors are called packages or photons. They are produced by each of the light sources each color absorbs, but this was very had to figure out because as you stare at one color it changes on you very quickly. This also led me to think that it has to do with the pattern of the light colors as well. Light Source || LUMEN ||
 * 1. Why is candle light flattering and fluorescent light makes people look "sick"? **
 * 2. Why are some sources of light a continuous spectrum and others a line spectrum? **
 * 3. How are the different colors of the LED candle produced? **
 * 4. Go online and compare the energy cost to run incandescent, fluorescent and LED lights. Create a table for easy reference. They are compared per "LUMEN" which is the actual amount of useful lighting. **

Bioluminesence:
It is a primarily marine phenomenon. Click Here Fireflies Fungus that glows

Fireflies:
There are many theories on how fireflies actually control their light but one thing is known for sure, the light is produced by two chemicals called luciferin and luciferase. For more info click Here

Through the production of luciferin and luciferase, which are two chemicals that mix to create the glow. There are two main uses of bioluminescence in marine animals, offensive and defensive. Bioluminscence has been used to view the cellular processes in human bodies. Click Here **Fluorescence** is a type of light that give of visible light very quickly and this happens in tow parts, through energy and hear, and the rest as visible frequencies. =EXERCISE 3:SCIENCE FOLDERAL AND BALDERDASH= 1) Nonsense 2) Nonsense 3) Nonsense 4) Nonsense 5) Nonsense 6) Real 7) Real Light beams can only be seen when different kind of particles are in the air, which means that beams from lasers and flash lights can not be seen from the side.

 * 1. How do fireflies make bioluminescence?**
 * 2. What are a couple uses of bioluminescence in marine animals? **
 * Offensive **
 * startle
 * counter illumination
 * misdirection:smoke screen
 * bugler alarm
 * sacrificial tag
 * warning coloration
 * Defensive**
 * lure prey: attract host, bacteria
 * stun or confuse prey
 * illuminate prey
 * lure with external light
 * mate attraction recognition
 * 3. Find a use for bioluminscence that has been created by recombinant DNA techniques. **
 * 4. In your own words explain what is the different between phosphorescence and fluorescence **
 * Phosphorescence** takes a very long time to absorb light and gives of visible light for a longer period of time, but the amount of energy needed to light up is more then what it give off.
