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

Materials: 

1. skittles

2. water

3. petri dish

4. Beaker

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 the petri dish around the edges.

Step 3: Pour 50mls water gently into the middle of the petri dish

Step 4: Watch as the water rewmoves the dye from the skittles. See wich colour reaches the middles fastest

Step 2:Rule a line 1 cm from the bottom of the paper strip.

Step 3: Put 8 ml of water into the bottom of the boiling tube.

Step 4: Draw two coloured pen dots on the pencil line.
