Skittles

Skittles

Aim: To separate colours from skittles by using the chromatography.

Definition: Chromatography is a method of separating out materials from a mixture.

Eg. blood, ink, drugs,

Materials

1. Petrie dish.
2. Water.
3. Skittle.

Process:

Step 1: Get the Petrie dish.
Step 2: Put All six skittle in the Petrie dish.
Step 3: Spread the skittles out evenly in the edge of the dish.
Step 4: Put some water to the top of the Petrie dish.

Conclusion: 
I learned in chemistry this week to make a rainbow skittle if putting water on because it was my first time doing it.  It was really the colour of the skittles expand and only stayed by not mixing theme. I learned that chromatography is the method of material that are away.
