Colourful Skittles

 Aim:

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

Method:

Equipment

- Skittles

- Petri Dish

- Warm Water

- Beaker 

- White Background

Instructions

1. Get your Equipment

2. Place Petri dish on the white background

3. Put your Skittles around the inside edges of the petri dish

4. Pour warm water gently into the middle of the petri dish

5. Observe what happens

Prediction: 

I think that the Skittles will get all the colour drained (become white).

Results and Conclusion

When the water was poured the colours started fading on the underneath and the colours drifting to the middle slowly.

Discussion;

1. The colours dissolved into the water  

(When a solid is mixed into a liquid, creating a solution)

Why did the colours spread?

The food colouring and sugar peels off staining the water, 

when you pour warm water over it the colour go along with the water

then spreading through the water into the middle till all the water is coloured)

Once the colours dissolved into the liquid

the high concentration of colour moved into the middle where there

was a low concentration of colour this is called diffusion
