Chromatography

 Hello everyone today i'm doing a post about Fizzy Drinks and Mentos. 

Our aim is to see which fizzy drink reacts the most to the mentos.

 Chromatography is a technique for the separation of a mixture 

by passing it in solution or suspension through a medium in which 

the components move at different rates.

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

Material:

   1.Skittles.

  2. Water.

  3. Petri dish.

  4.Baker.

Process :

step 1: Get your equipment, set up ready to pour the 50mls of water into the petri dish with the skittles.

step 2: Place the skittles into the petri dish.

step 3: Pour 50mls water gently into the middle of the pond.

step 4: Watch as the water removes the dye from the skittles. See which colour reaches the middles fastest.

step 5: Record your result on the table below.
