Tye-Dyed Milk

By Justice room 19

Question Will the food coloring react the same way to other liquids?

Hypothesis I think the food coloring will not react to other liquids, because the dish soap has bipolar characteristic.

Variables Controlled :Milk Bowl Food coloring

Manipulated:Vinegar Dish soap
Responding:The movement of the food coloring.

Materials  1/2 cup milk

2 bowls
1drop each of four different food colors
1cup dish soap
1 cup of vinegar
20 q-tips

Procedure 1.I will gather my materials.

2.I will measure the milk evenly and pour it into each bowl.
3.I will measure my dish soap and vinegar and set it aside.
4. Put 2 drops each of red , blue , yellow, and green food coloring into the milk.
5.Next dip the q-tips into the vinegar and dish soap.
6.Then I will dip the q-tip with dish soap into the milk.
7.Then I will dip the q-tip with vinegar on it and dip it into the milk
8.I will observe the reactions.
9.I will record the result.

Conclusion My hypothesis was correct because the vinegar did not have bipolar characteristics.So the food coloring did not move around the bowl and there was no movement.

Research  *The molecules of fat bend, roll, twist and contort in all directions. The soap molecules race around to join up with the fat molecules.

*During all this movement of fat molecules, the food coloring molecules are bumped and shoved around everywhere.
*As the soap becomes evenly mixed with the milk the action slows down and eventually stops.
*The molecules are nonpolar on one end and polar on the other end) weakens the chemical bonds that hold the proteins and fats in solution .
