I Can See Clearly Now, The Rain is Gone!

Yeah I really don't know what the title has to do with lights (which is what were talking about today by the way), but, I mean, if you see clearly and the rain has gone, wouldn't the light come out? Just saying...  


  Well anyways today were gonna be talking about lights. Light is (as approved by the dictionary... or my science book I guess..?) electromagnetic radiation that YOU CAN SEE. You know how I talked about the electromagnetic spectrum? (which you can find here) Well, on the ES, there's a section called visible light, which again, we will be talking about today. Now, you're probably dying to ask how light travels, and where some sources come from? I know, I was too ;) 

I feel like such a five year old with all these pictures 

  Where does light come from? Well, the sun obviously (like Mr. Sun as seen above) shines reeeaaaallllyyy bright. The sun is a natural source of light. Some animals even make natural light, like little fish that live at the bottom of the ocean, called angler fishes.

Aw! I'm sure some of them are nice :)

  Now some of you may be thinking that the moon is a natural source of energy. But alas, that's wrong. The moon just always reflects light from the sun. Sorry!

 
Cheater.

  Now were going to talk about some things that light can do. It has many "powers", per say, like traveling for example. Light travels at 186,000 miles per second (that's 360 million miles an hour), and it's the fastest thing us humans know to exist. We haven't traveled at the speed of light, but we've gone "very very nearly almost as fast" (credit to charlieissocoolike in his lights video). 

It's supposed to be a running light bulb, okay? Geez, people. 

  Another thing I'm gonna talk about is color. Everyone likes color, in pictures, in clothes (except for this crazy color trend that's going on... me, I prefer to wear blue) and pretty much everything else! But do you ever wonder where colors come from? Well, they come from light. 

Pretttttyyyyy Flower

  The colors we see are actually white light. These white light waves that are visible to the human eye, and we see them as the colors red, orange, yellow, green, blue, indigo, and violet. The colors of the rainbow! NOW THE PICTURES ABOVE MAKE SENSE! 



  So, if all the colors are in white light, how can we tell what color is which? How can you tell this font is purple? How can you tell my shirt is navy blue? Well, actually.... nevermind about the shirt thing. Anyways, the answer to that question is because light get absorbed! If my shirt is blue it's because all the colors (roygbiv) are absorbed but blue, which is reflected off the shirt! So I guess it'd be more a roygiv, because the blue is reflected.... (just a nice science joke for you guys out there). 

 

  When you think about colors, and where they come from, it can be kind of confusing. But hopefully now you know, and I explained well enough. Now if you're wondering, "Is this like, some kind of reflection paragraph or something?" Well, YES, it is a reflection paragraph, because, I talked about how materials reflect colors up there^. See what I did there?? Hehe.


Oh my gosh!!! :) Babies are so cute. 

  Well that must be it for my blog. I hope you enjoyed and... yeah. SuperSaraSuperBye!

AT THE SCIENCE FAIR..! (yeah that's all I know)

  Hey guys! So right now it is a very special time of year.. The Science Fair. Whoop dee doo (props to cheeba). No, but really, the science fair is okayyy. Like, not terrible, but not great, or fantastic, or any other synonym you can think to describe good things. Anyways, this year I asked the question "Which Hair Dye Stays In the Longest?". Yeah, kinda boring, but still a cool project in my opinion :) So I started out by buying my materials.


  The first thing I had to buy was 100% real blonde human, which was really creepy. Like, REALLY creepy. The next thing we had to buy was the hair dye, and I bought Nice n' Easy, ColorSilk (aka the WORST working hair dye in the history of the universe).


Clairol Nice 'N Easy Permanent Hair Color, Natural Radiant Auburn 112B

  MATERIALS: 

-       Garnier Nutrisse hair dye in Medium Intense Auburn
-       Clairol Nice n’ Easy hair dye in Radiant Aubrun
-       Revlon ColorSilk hair dye in Burgundy
-       100% blonde human hair put into four sections
-       Shampoo for colored hair
-       A hairdryer



  After I bought my materials, I  made my hypothesis. 

HYPOTHESIS:

  If I test out Garnier Nutrisse natural hair dye, Revlon ColorSilk (ammonia free), and Clairol Nice and Easy (has ammonia)on blonde human hair, than Clairol Nice and Easy hair dye will stay the longest because it has ammonia, a key ingredient to making hair dye stay through 10+ washes.

I know, pretty long, but I wanted to get my point across. The next thing I had to do was... well, actually do the experiment. 

PROCEDURE: 

  So I took my hair segments and I followed the directions to dye the hair. Then, I washed the hair over, and over, and over, and over, and over, and over,  and over,  and over,  and over,  and over. That's right, TEN TIMES! It took soooo long. Did I mention I had to blow dry and take pictures of the hair each time? But even though it took a long time, I'm glad I found my answer, which was...


                 Me scrubbing hair

                 Me pouring hair dye

                               10th wash close-ups

CONCLUSION: 

  Well, After I tested out the hair, it turns out the Garnier Nutrisse worked the best! The hair afterward was so red after even ten washes and it was really soft! So that won easily out of the three hair segments. I'm really happy with the turnout of my project and that I actually won third place! Yay! Now for the funny pictures.
Okay... So this is actually pretty funny. You see how he's so depressed that he won? I don't know why but cheeba and I were just laughing so hard at how sad this kid looked. Then halfway I realized she was girl... which is actually pretty easy to tel so now I look even more blonde than usual. So, yeah... sorry Emily. I feel really bad now. But girl or boy this is still hilarious.
