Things become visible to the human eye when light bounces of it. The light is the first step to make the illuminated object visible. However, that is not all that it takes there are still more to it. First light bounce off the object, then the object reflects one color of the light and it hits your eye. First, the light travels past your cornea, then to the aqueous humor, next, to the iris, then finally to the pupil, where light is going into the internal eye.
     In the internal eye, the light go past the vitreous humor, next to the retina. Then the most important spot the blind spot, the entrance to the optic nerve, so you could define what the object is. The optic nerve leads to the brain, where objects are define. Therefore, that is how light and objects can be seen.
     
 
     My animal was the black swan. I had been researching and creating projects about the animal for a few weeks. Even though the animal I saw didn't fascinate me, I think it was because I already saw it. Or it could be that the animal was to far away, and I couldn't see it up-close. Well, as you can see, when I was half-way through my work, my family and I went to San Francisco Zoo. Over there I saw my animal up close, and even though it was only a short while, it had an effect on me. 
     The black swan at the Chaffee Zoo was different from the black swan at the San Francisco Zoo. The black swan at the Chaffee Zoo was quiet and quite peaceful. However, the black swan I saw at San Francisco Zoo was quite gentle and made soft honking sound. The swan there wasn't noisy, it was actually very peaceful. Therefore, I think that I was fascinating when I first saw my 
 
     Most people said that rainbows form from simply just water and light. Well there's more to it. In nature, the sun's rays are like light and water is like mirrors. As you can see, people don't really use light and mirrors to create rainbows, but use light and water. When the sun is up after a rainy day a rainbow forms and that is how rainbows started. Since the sun's rays are like light and water is like mirror, when the sun is up after a rain storm the light of the water dew or droplets refracts with the sunlight and becomes visible. Therefore, that is how nature creates a rainbow. Light isn't visible until it is refracted or bend. Refraction happens to make light visible. 
     Rainbows form when light and mirrors join in the same way. Except that now you are using mirror and light instead of water and sunlight. When turning on the light, use the mirror to reflect the light a specific way and a rainbow will appear. As you can see, making rainbow is really simple to how it forms.
 
     At first my idea of why is the sky blue was partly correct, but it still needed more information. I research that that the sky is blue because there are small particles or elements. That made up the sky, and it is blue because our human eyes see it that way. As we head further into space the particles spread wider apart than it is on Earth. It spreads more because there is less gravity. Then the particles receives light from the sun and reflects the blue light and absorbs all the other light. Also, our eyes see the sky to be blue, so therefore, the that is why the sky is blue. 
     As you can see, the sky is blue because of various of reasons. It was because of the sensitive human eye and the particles and the effects of light. The sky may be blue for other of various reasons that we don't know.
 
     There are three reasons why I think that the sky is blue. One reason is of all the molecules or elements in space that cause the sky to be blue when light shines on it. When lights from the sun and stars shine on the sky it may reflect blue light. Therefore, the sky absorbs all light. The sky is like a thing and absorbs light and reflect light. Another reason is that the sky reflects water on Earth and that made it the way it is. Since the water is like a mirror it reflects the sky and then the sky changes color. 
     Another reason may be that every organisms' eye can only see the sky this way. Therefore, the sky doesn't have a change. Our eyes just see and function like that. These are three reasons why I think that the sky is blue. It can be because of the the molecules that reflect the blue light, reflection of water, or our own eyesight.
