Skittle Colours Experiment

 Skittle Colours

Aim:

I want to find out what happens when you mix Skittle colours.

Method:

Equipment:

• Skittles
• Petri dish
• Warm water
• Beaker
• White background

Instructions:

1.Get your equipment

2.Place you Petri dish on the white background 

3.Put your skittle around the inside edge of the Petri dish

4.Gently, Pour warm water into the middle of the petri dish 

5. Observe what happens

Prediction: 

I think that the colours are going to spread out around the water and slowly mix, and the main part of the skittles are going to turn white and maybe start Turing the shell remain clear. 

 

I noticed that the colours started to spread towards the centre of the dish and mad a triangle shape. 

Discussion:

1. The colours dissolved (When a solid is mix into a liquid, creating a solution). 

Why does the colours dissolve?

REASON 1:

The reason food colours meet in the centre of the plate and not mix is because the food colour has the same sugar amount dissolved from each skittles, when the sugar dissolves it pushes outwards into the rest of the solution, sending the colour outwards as well.   

REASON 2:

The skittle colours have tons of molecules and molecules don't like to be near other molecules so the colour spreads outward towards the centre where no colour is, so it diffuses (spread over a wide area or between a large number of people) towards the centre.
