I think they are from different places, cause one girl was wearing a school uniform...I think....I guess she could have just been wearing a blazer for the fun of it....I mean who wouldn't want to look extra sharp for the school science fair?....... You know I was asked to be a judge at my cousin's middle school science fair....I think I might bring my camera just in case....
My daughter did her science fair project on body gas and how it is made and what makes it stink and myths about them. She called "Pull My Finger" it was good. Some parents didnt like it but many cracked up. Plus it had some really good science in it.
that's pretty legitimate... a dog can't see many colors... "Cone cells contain pigments that perceive specific wavelengths of color. Human vision is trichromatic -- we have three types of cones that recognize different portions of the color spectrum. These cones allow us to see a range of colors that are a mix of red, blue, and green pigments. Dogs have only two types of cones -- their dichromatic color vision is similar to that of a human with red-green color-blindness. In addition, a dog's retina contains a much smaller ratio of cones to rods than ours does. An article about Canine Vision, written for a college psychology course, includes a graphic that contrasts the yellow, blue, and gray spectrum of the dog's world with the familiar rainbow of colors we perceive."
