Optical Ilusion

My question is: Do more girls perceive Optical Illusions than Boys?
I am going to show three Optical Illusions to 15 boys and 15 girls to see if they perceive them. If the boys or girls perceive only one of the Optical Illusions that means they don’t see all illusions. I chose to do this experiment because some people told me that girls know Optical Illusions better then boys and some said that boys do, so I wanted to find out by doing this project.

I think the number of girls and boys perceiving Optical Illusions will be even. The reason why I think it will be the same is because I don’t think there is any difference between girls and boys perceiving Optical Illusions better or worse. If some boys and girls already know about Optical Illusions it won’t be correct anyway. Some students might see Optical Illusions differently then others may. Everyone has a different way of looking at them. Some boys may see the same illusion as others or some won’t see anything and some girls might see the same illusion, something different, or nothing same as the boys. That’s why I think the number of boys and girls perceiving Optical Illusions will be even.

[pic][pic]Controlled variables: The controlled variables that should be kept the same are:
1. The number of girls and boys.
2. The number of Optical Illusions.
3. The kind of Optical Illusions for each boy and girl.
4. The grade the boys and girls are in.

Manipulated variable: The manipulated variable should be changed in order to see what happens is the type of gender.

Responding Variable: The responding variable that changes as the result of changing something is the number of girls started to perceive Optical Illusions more than boys.

Materials:
My materials are
    1. 15   grade 6 girls
    2. 15 grade 6 boys
    3. Three Optical Illusions on a paper.

  I first made a tally sheet with my question on it. Then I asked 30 grade sixes to do the Optical Illusion test....
