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).

  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.

This is awful!!!

  Well... that's all! SuperSaraSuperBye!!!

It's Electro!... Magnetic. Boogie Woogie Woogie

  Hey guys! SuperSara here. Today I'm going to be talking about the electromagnetic spectrum. I have no idea what this is, but, I think that may just be a good thing. I want to start each new blog by writing a paragraph as an uneducated person. Then, I will read/study the topic and write the rest. I think this will give good perspective that when I write these blogs, I actually AM learning stuff, not just writing about what I know. But anyways... Here is my "Uneducated Paragraph".

UNEDUCATED PARAGRAPH 

  You know when you're outside holding sunglasses, a piece of glass, a mirror, etc., and it makes these little rainbow patterns? The light looks like a rainbow..? That's what I think the electromagnetic spectrum. It may be some kind of...list or... pattern... or graph or... whatever. But anyways, this "list pattern graph whatever" shows the light your eyes are able to see? Maybe? I don't know. So that was my uneducated paragraph. Hope you enjoyed. 

   Okay, so here's the legitimate definition of the electromagnetic spectrum.

Electromagnetic Spectrum:  The entire range of electromagnetic waves with different frequencies and wavelengths. 

  I just think of ES as a bunch of types of radiation, organized by amount of energy. Now you may ask what radiation is. It's basically just any movement of energy of through energy. Now there are many properties of the ES. Let's go over them! 

Radio Waves: About the weakest wave on the ES. These are categorized into three different waves: AM, FM, and television waves. TV is high frequency, FM is medium, and AM is low. 

Hehe... I made this one ^

Microwaves: Used in airplanes and microwaves. Pretty simple. Microwaves actually use microwaves! They do this by releasing radiation into the particles in your food, that cause them to move and create heat! Thus making your food warm! Yum!

Infrared Waves: These are often produced when an object radiates heat. You can't see it, but you can feel it. These are used in remotes. 

Ultraviolet Waves: UV waves naturally occur in sunlight and in large doses can give you skin cancer and cataracts (blindness). Make sure to wear your sunscreen! 

  X-Rays: These waves have high penetrating power. They're used for x-rays, obviously, and can travel through anything. These can be really dangerous if you're not careful. 

  

Gamma Rays: These are are the most powerful rays on the electromagnetic spectrum. These are used in NUCLEAR BOMBS and are absorbed by our atmosphere.

Okay well those are the terms... Here are some random facts about the ES!

• Waves on the ES are organized by how much energy they carry. (Which is really how short the wavelength is, which is really just the frequency)
• SONAR uses microwaves
• If the ozone layer did not block the sun's UV rays, rates of cancer would skyrocket.
• Thermographs are those cool heat pictures :)

  Okay guys well that's it! SuperSaraSuperBye!!!!

Hope an ANVIL Doesn't Drop on Your Head!

  Hey guys! Today we will be talking about hearing, because I'm about to lose my voice :( Honestly it's nice to be writing because I can ACTUALLY say things... I've been writing things on a whiteboard all day! So, yes, back to hearing... let's start learning! Let's go over what hearing is.

  Okay, so as you guys know sound waves are made of vibrations. They are mechanical waves, which means they need a medium to travel through. Sound waves travel at 344 meter p/s, so it takes a sound wave about a hundreth of second to get to our brain, using the process I will explain NOW: 

  Okay, so there are three parts of the ear. The outer ear, the middle ear, and the inner ear. I'll go over each. 

THE OUTER EAR: 

  The outer ear is the visible part of the ear. You know the rim on your outer ear? It actually has a purpose. It catches sounds that are sent to your middle ear. Let's see what that is.

THE MIDDLE EAR:

  This is where all the cool stuff happens. When the sounds go inside the ear, this thing called the ear drum (which works like and actual drum) makes these sounds you hear into vibrations by to be sent to the inner ear, which we'll take about next! 

 

THE INNER EAR

  In the inner ear there are cells with tiny little hairs on them. The vibrations your ears just made tickle the hairs and send signals through nerve fibers to the brain that then translates these into what we hear! This may be a very long process but it only takes about .01 of a second for it to happen!

  

  Next we are going to talk about three of our bodies smallest bones: the anvil, the hammer, and the stirrup. These bones are all in your ear. The hammer passes vibrations to the anvil. The anvil passes helps pass vibrations from the hammer to the stirrup, and the stirrup passes this to the cochlea, which is basically just the little hairy cells again :)

From left to right: Hammer, Anvil, and the Stirrup. 

  Hearing is part of the five senses, and we use our hearing alot. But imagine if we didn't have the ability to hear. Many people are this way, and it's also known as being deaf. Deaf people do have it very hard, and you can become deaf many ways. You can hear something to loud that may burst your eardrum, get an infection, or it may just be hereditary. But don't worry, deaf people have ways to communicate. They use sign language. 

  Sign language is a language used through hand movements and was created by... well, know one really knows. The first accounts of it were in the fifth century. Sign language is relatively easy to learn in my opinion, alot easier than Chinese or Arabic. Well, at least ASL, or american sign language is. Because we already speak english! 

  Well... that's it! Hope you guys enjoyed my blog!! SuperSaraSuperBye! Sorry for the short blog!

Good 'Ol Caroloke. She says happy almost leap day! 

How Does This Sound..?

  Hey guys! Today I will be talking about sound. So recently I have become pretty much obsessed with that show, "Switched at Birth", and I am learning some really cool sign language! I would show you if I could... but anyways when Mr. Sellers told us we were learning about sound I immediately thought of that show and how hard it would to be deaf... not able to hear music... yeah that'd suck. I also thought of how I get to post charlieissocoollike's video on sound! WAHOO! Anyways, now that my awesome but totally off topic intro is done... let's start.

  Sound can make you think of many things... music, audio books, even just another person talking to you. But do we ever think about the science behind it? HAHA, I know I don't. This reminds me of a time when my grandpa asked me if I knew how a record player worked. I said "Yeah, of course." kind of uneasily. "You put the record in and it plays music!" Yeah... I need to learn a little more.

  Okay, so now let's talk about some basic elements of sound. Sound is actually a vibration that travels through air made by whatever produced it. Echolocation uses sound to see if they are things in bodies of water, and it used by bats and dolphins. They send out loudly pitched sounds (it must have a high frequency) and the sound bounces back to them so they can detect where whatever theyre searching for is. Now for some vocabulary words! 

Loudness: A human's version of explaining how much energy a wave is carrying. Remember, the more energy a wave is carrying the louder the sound is. Same goes with amplitude. So if you're at a house party, and you say "TURN THE MUSIC DOWN!" and then the other person says "TURN THE MUSIC UP? OKAY!", those waves would be carrying alot of energy :)

Create a gif

Pitch: The certain frequency of a sound. If a sound has a high frequency it will have a HIGH pitch. If a sound has a low frequency it will have a LOW pitch.

Amplitude: Basically the same as frequency. Higher means higher sound. Lower means lower sound.

Echo: When a noise hits a wall, the higher frequencies usually get absorbed. But, if a wall is hard enough then the sound will bonce off, and create and echo-o-o-o-o.

  Now I'm going to explain the doppler effect. Remember the video on lights I showed you last post? Yeah, I'm going to explain it like Charlie because it sounds so much easier. The Doppler Effect is the change in a frequency of a wave when it is moving relative, or away, from you. So if a police car passed you, as it was coming towards you, the pitch of it's sound would be higher, and this is because the sound waves get squished up. As it was going away from you, the pitch would be lower, beacuse the sound waves get stretched out. Below is an extraordinary picture I MADE. 

  Here it is, what you've all been waiting for..... the video. YAY IT FITS PERFECTLY! 

  So that is my blog... hope you enjoyed. SuperSaraSuperBye!

Property of Sir Wave Length Medium- Amplitude of Frequency Town in Hertzville

Hey guys... guess what? I have this thing. A thing that makes it the hardest possible task in to world to do when you have to write a blog: WRITERS BLOCK.

So yeah... Today I will be talking about Wave Properties. Thus my insanely weird title. Okay so let's go over some vocab words...

Frequency: The number of times a wave passes a given point in one second. It's measured in hertz, or waves p/s. Frequency is also related to wavelength. A wave with a shorter wavelength will have a higher frequency, and vice versa. So let's say they wanted to see what the frequency of a wave was. If the wave passed the point 8 times in one second, the frequency would be 8. Easy as pie... or finding the frequency of a wave...

Amplitude: Distance between the crest and midpoint of a wave. The amplitude is also the measure of how much energy a wave is carrying- more energy means a higher amplitude. A large sound wave is more likely to hurt your ears because it has a greater amplitude.

Steps to get this photo
Step 1: Download brainpop app and watch video on your phone.
Step 2: Take screenshot at appropriate part of video.
Step 3: Go into your photo library and crop the photo.
Step 4: Email it to yourself and attach it to blog via the internet. 

  Next were going to talk about... FIREWORKS!!! Did you know that the reason that you hear a fireworks display before you see it is because sound travels at 343 meters p/s, while light travels at about 300 million meters p/s, which is pretty blooming fast (only the people who saw the lights video in my last blog will get that one). 

  Okay, so the speed of a wave can be caused by many different things. The formula for speed is speed= distance/time. So all of these factors determine how fast a wave is!

A picture that really sums everything up! 

  Okay guys well that is my blog...hmm... for some reason I typed "long" and had to go back and fix it.. SuperSaraSuperBye!

Wave Properties- Pretty Basic Stuff

A Kid's Website for You Younger Folks

I have decided that Caroloke's birthday is August 17th. It's the first date that popped in my head. 

I "wave" to You Hello

Hey guys, SuperSara here, and today I'm going to be talking about waves. Well that was a really boring intro, wasn't it? Oh well. So today we have to talk about the relationship between waves, energy, and matter. I haven't learned this yet, so PLEASE bear with me. By the end of the blog we both will know more!

  Okay, so during every moment of our lives, we are struck with waves of energy. Most energy waves collide with us or pass right through us, and we don't even notice. Another big part about waves is matter. Waves carry energy, not matter.  But, matter can be used to transfer waves. Let's go over a few vocab words. 

Mechanical Waves:  Waves that use matter to transfer energy. Water, sound, and earthquake waves are examples. 

Medium: The matter used to transport waves. Mediums can either be solid, liquid, or gas. 

The Medium here woud be water; This is an example of a mechanical wave. 

Electromagnetic waves: Waves that do not require matter to transfer energy are electromagnetic waves. Radio waves, x-rays, microwaves, and visible light waves are examples. They can all travel through empty space and all travel at the same speed, which is sometimes called the speed of light. 

  Now let's talk about tranverese/ longitudinal (I prefer to call them tuna) or compression waves. Mechanical waves can be classified into either one according to the motion of matter involved, while electromagnetic waves are a special type of transverse wave.

Tuna or Compression waves: Mechanical waves in which medium matter moves forward and backward in the same direction the wave travels. 

A slinky is an example of L/C waves

Transverse waves: These can be classified into Mechanical waves, and yet electromagnetic are a special type of transverse. Matter moves up and down or back and forth at right angles, compared to the direction of movement. 

Now for a short little story about Leonardo Da Vinci. 

  Once upon a time, in the fifteenth century, Da Vinci was sitting in his office, and he observed an observation about waves. (because that's totally not what this blog is about ;) He observed that while waves move, the medium does not. He then stood up and said "Like the waves made in a field of grain by the wind, where we see the waves running across the field while the grain stays in place." He basically meant that waves move the medium. 

Here is a really cool video by the most awesome british guy on youtube, Charlieissocoollike. In this video, he talks about lights, but he also has some pretty cool stuff to say about waves too.  And yes, I know, the video sticks out of the frame. That is my blog. Oh well. Live on your lives, people. 

  Well, that is really it for this blog, and I hope you enjoyed. Below you will find some links. SuperSaraSuperBye!!
