Saltwater Formation

The intent of this experiment is to demonstrate the formations of the world oceans and why they are salty. I hope to learn more about the formations of the world oceans and what causes the oceans to be salty. Based on my research, I know that if salty water was put on black paper and left outside in the sun, the water would evaporate but the salt crystals would stay. The salt would not evaporate because it is a solid. Knowing this I formed a hypothesis, being, if salty water was poured on black paper and left out in the sun, the water would evaporate leaving behind the salt crystals, causing the part that the salty water was poured on to turn white.

METHODS
Materials: Salt Potting Soil coffee filter plastic cups black construction paper scissors tap water
spoon
5.When all of the water has dripped out onto the paper, bring the paper out in the sun to dry, placing a llllll onto the part that is not wet.

ANALYSIS

1.) My hypothesis was, if salty water was poured onto black paper and left out in the sun, the water would evaporate leaving behind the salt crystals, causing the part that the salty water was on to turn white.
2.)My independent variable was the amount of soil and salt that was put in the coffee filter.
3.)My dependent variable was the color of the paper.
4.)This was a controlled experiment because I could compare the paper that I used to how it was before, or another one that was the same.
5.) The reason that I used black paper as opposed to white, was because the salt was supposed to make the part that the salty water was poured onto turn white. The white caused by the salt would not make a huge difference on the white paper.
6.) The black paper did not turn white and I am not completely sure why. The dried paper suggest that salty water makes no difference than if fresh water was
