Light Spectrum

The colors are ROYGBIV: Red, Orange, Yellow, Green, Blue, Indigo, and Violet, in the light spectrum. Three types of spectrums are Continuous, Emission, and Absorption. . . 

Taking time to write what we saw with each chemical, as a class we discussed and wondered why it did what it did. The causes of the lights thats we shown and why some werent. We learned these words--->

CONTINUOUS SPECTRA: another name is thermal spectrums, they have ever light and wave. Show all the colors in the rainbow. So all in all, it shows ALL the colors.

EMISSION:  when the light passes through, the energy is lowered or weakened, being able to see little amount of light.

ABSORPTION: some light is absorbed by gas and only some can pass through.

Now we did some experiments and discovered light through different chemicals and this is the results we got------->

After separating mixtures. . .

The Very Next Day!

We used those filter sheets that i was talking about and drew a image on it with colorful markers. After that we poked a hole right in the center and rolled up a piece of paper towel into the hole. Placed the whole thing into a thin flat container full of water. With the rolled paper towel sucking up the water into the filter, it began to move the colors. In the end, the blue color was very easy for the water to move and was all on the ends. However, the green had a difficult time moving with the water. This whole process is called chromatography. Its a chemical separation for substances like ink. In ink. molecules have different characteristics such as size and solubility, this effects the speed of the movement. Soon enough our drawings looked like this---->
