Abstract (Angel): In our experiment, we needed to learn about light and how it is measured studying the electromagnetic spectrum in order to create light, or wavelenghts of light. We will need to see which type of color light will affect an evaporation time as fast as possible. The alcohol has to be evaporated using the colors blue, red, and green. We will do this 5 times for each color light and get our results.As we were doing the experiment, we saw that the color red was not evaporating as fast as the green one and that the blue color light was the fastest to evaporate the alcohol. We saw that the darker the light is, the less frequency and energy it has. Things could have been more accurate if everything was computer genetic. The different frequencies of light have different amount of energy as shown in the analysis.
Purpose (Brandon): (use 3rd person, no "you") The purpose of making this project was to show that there are many different frequencies and wavelengths of light. There are also many different colors as well as wavelengths. There different colors are blue, red, and green.
Blue is the strongest and most powerful color in the spectrum because as seen in Hertzsprung-Russel's diagram blue is also the superior color in heat. One might think why do i need to know this? Well this comes in handy in the field of science. This helps show how many wavelengths or frequencies something has. This helps people positively because it helps them find out many things about life and the universe around us.
History: (Brandon): A travelling transverse wave of electric and magnetic fields is known as an electromagnetic spectrum. The discovery that a beam of light was actually an electromagnetic wave was made by J.C.Maxwell in 1865 (source?). He was the first person who found out how the spectrum worked. He found out by formulating a series of equations. The term Spectrum was first used in 1666 by Issac Newton (source?) . He found out by putting a glass prism into the light, let out many colors. He was fascinated by the phenomenon and called it the spectrum. He saw that it had 7 colors and that the number 7 was magical all around the world.
Process (Angel): This project requires the knowledge of the electromagnetic spectrum. We will use it to create different lights in order to create different frequencies of light. These different frequencies will have different amount of energy to produce evaporation. This would show that which frequency of which light can produce the most energy to evaporate the fastest. Usually people say that the brighter the light is the more energy it produces.
Application (Angel): This project is useful for scientists to help them find out about distant stars and how bright they are. Since the color light blue is the brightest color, then any sun that is blue, has to be the brightest and hottest star out of all of the rest (source?). Scientists can see that the blue colored sun's rays will evaporate a planet's and can tell if the planet is suitable for it to have life.
Problem (Brandon): Do different frequencies of light contain different amounts of energy when used to evaporate a single drop of Isopropyl alcohol(rubbing alcohol)?
Hypothesis (Brandon): If a light spectrum is created then, the color blue will have a higher amount of energy because of the way blue transfers energy faster.
Variables (Angel): wrong order
CONTROL- same amount of alcohol used, same distance of LED, same distance of alcohol placed
DEPENDENT- LED lights(red,green,blue)
INDEPENDENT- rubbing alcohol
Materials (Brandon): (how much of each? dimensions?)
LED Lights (Red,Green,Blue) A bottle of Isopropyl alcohol (rubbing alcohol)
Pipette
Stopwatch
Small Cardboard box
White Cardstock
Index cards
Procedure (Brandon):
Make a small three-sided enclosure from a cardboard to minimize air currents (reduces basal evaporation rate). The enclosure will also minimize illumination from light sources other than the LED. The open side allows you to observe the evaporation of the isopropyl alcohol.
Place the white cardstock under the three-sided cardboard. This will protect the platform underneath from dripping alcohol.
Use the eyedropper (or transfer pipette) to place a single drop of isopropyl alcohol (rubbing alcohol) on an index card.
Measure evaporation rate, ( in seconds, )with each LED as an illumination source.
Repeat each test condition 5 times for each color light.
Calculate the average evaporation time for each condition.

Glossary (Angel):
Electromagnetic Spectrum- the entire spectrum, considered as a continuum, of all kinds of electric, magnetic, and visible radiation, from gamma rays having a wavelength of 0.001 angstrom to long waves having a wavelength of more than 1 million km
Frequency- the number of cycles or completed alternations per unit time of a wave or oscillation.
Hertz- an SI unit of frequency, equal to one cycle per second.
Infrared light- electromagnetic radiation with wavelengths longer than visible lightbulb shorter than radio waves.
LED- light-emitting diode: a semiconductor diode that emits light when conducting current and is used in electronic equipment, especially for displaying readings on digital watches, calculators, etc.
Magnetic Field-a region of space near a magnet, electric current, or movingcharged particle in which a magnetic force acts on any othermagnet, electric current, or moving charged particle.
Ohm's law- the law that for any circuit the electric current is directly proportional to the voltage and is inversely proportional to the resistance.
Ultraviolet light- radiationlying in the ultraviolet range; wave lengths shorter than light but longer than X rays.
Visible light- electromagnetic radiation that produces a visual sensation.
Wave length- the distance, measured in the direction of propagation of a wave, between two successive points in the wave that are characterized by the same phase of oscillation.
Analysis: (do not use 1st person, "we") The results of the experimentation were that the color blue had a higher frequency of energy than red or green.because it took only about an average of 31 seconds while the green had an average of 43 seconds and red had an average of 51 seconds. This proved our hypothesis that the blue light evaporated the rubbing alcohol faster. We saw that the brighter the light is the more frequency it has because there is more energy and visibility in brighter lights.
Conclusion (Brandon): (hypothesis correct?) We believe that different frequencies of light does contain different amount of energy because each color light took longer to evaporate than the other one. We made mistakes by not placing the light in the same place or the alcohol in the same place. We used a phone stopwatch and that may not have been accurate so next time it might be computer timed to be more accurate with the timing. The place where the alcohol was placed might also not be accurate because it might've been a few centimeters away than the initial distance. (next steps?)
