1 Problem If I put highlighters in water, will it make it glow with a black light? Hypothesis I think that the water will glow for all of the colors except for the yellow highlighter. Materials Some of the materials that I'm going to use are: highlighters blacklight water cups scissors

2 Procedure 1. Measure 1/2 cup of water. 2.Pour the water water into the cup. 3. Carefully break open the highlighter with the scissors. Take out the felt and put it in the cup of water. 4.Find a dark room. 5.Turn on the black light near your water, and record how it looks? 6.Continue to observe the water and record the brightness of the glow. 7. Repeat steps 1-6 with other color highlighter. Variables Highlighter vs florent highlighter 1 min vs 3 min vs 5min

3 Results Yellow - thin highlighter No Kind of Yes Blue- thin highlighter No No Yes Pink- thin highlighter No No Kind of

4 Yellow - thick highlighter Kind of Yes Yes Blue - thick highlighter No Kind of Yes Pink - thick highlighter No Kind of Yes

5 Observation I noticed that the thick highlighter worked best then the the thin fluorescent highlighter. I also noticed that the thin highlighter, and the yellow glowed like the sun. And the thin pink highlighter didn't even glow, but the thick one did and it looked orange when it was thick, and the blue one did not glow at all, and the other pink one didn't look pink or orange, because sometimes it turns different than the color it really is.

6 Conclusion I learned that the thin Markers make the yellow felt glow best. Because When the black light reflexes on to the water, and makes it glow like The sun, and it was a Lighter color. And the blue Kind glew, because it's a Little darker, and the felt juice didn't want t out. And the pink marker didn't glow that we'll because the black light didn't make the felt come out. And the thick yellow one glew more than the thin, because they were fatter and you have to squeeze the thin ones and the thick to so the blue, pink and yellow thick ones so I squeezed all of them to come out. And to let the black light hit the water to make it glow in the dark.

7 Research Luminescence Luminescence, light causes other than high temperature. Incandescence is due to the heat that's called Incandescence. And luminescence may occur in a liquid, solid and gas. Phosphors can become a solid object that will become luminescence that is called phosphors. There is a chemical reaction,m there is one kind of luminescence that reacts to the chemical reaction. Some examples are bioluminescence (luminescence in a living organism), like a firefly. Another kind of luminescence that's a object subjected by source of energy. That means other things could mean luminescence, thus and lining of a fluorescent tube produces light when it receives energy from ultraviolet radiation, Barium sulfide glow when struck by X-rays. Science.howstuffworks.com/Luminescence-info.htm Electromagnetic spectrum The electromagnetic spectrum radiation is the range of all types of electromagnetic spectrum. Radiation spreads energy that travels as it goes, to types of electromagnetic radiation of radio waves, some types of electromagnetic spectrum radiation that make up the electromagnetic spectrum are X-rays, and gamma rays, infrared light and ultraviolet light. And electromagnetic spectrum is a range of all possible frequencies of electromagnetic spectrum, it is a object of different meanings thereby covering wavelengths from thousands of kilometers down to a fraction of the size of an atom. Spectroscopic, and that is a probing interaction, electromagnetic spectrum are used in science for probing interactions.

8 Imagine.gsfc.nasa.gov/docs/science/know.com Glowing water Ingredients in highlighter A highlighter contains materials and ingredients that allow it to glow in the dark. The phosphors make the water to be glowing water as well as the felt inside the highlighter, because we can't see the phosphors, but when you shine that black light on the water, it will turn out so we can see it, and it will make the water glow. And if you were to use tonic water, the u.v. Light will react with the phosphors inside a chemical used in tonic water that's called quinine. Definitions radiation - it travels through matter-containing media, and it is a process in which electromagnetic waves. Bioluminescence -it is emission of light by a living organism. Emission - it is many gases like a variety of flue gas, and exhaust is a fuel its occurring like flue gas.

Light is an important form of energy for all of us

What is Light? Light is an important form of energy for all of us it allows us to see plants rely on light for photosynthesis many chemical reactions produce light life on Earth would not exist without
