Aim: to use water to extract the dye from the skittles using the process of chromatography.
Materials:
- 1. 5 Skittles
- 2. Water
- 3. Petri Dish
- 4. Beaker
Process:
Step 1: Place the skittles into the petri dish around the edges.
Step 2: Pour 100ml or 50ml(depends on how big your petri dish is should be half way) water gently into the middle of the petri dish.
Step 3: Then watch the colours spread around the petri dish until it is done.
Step 4: when it is done you can tip it out in the sink
Explain the findings
Why do they bleed out at the same rate? because it is sugar
Why do the colours not mix together? because it is sugar
The fastest colour was... Yellow
