Method:
1. 1/2 fill a petri dish with water
2. Carefully place 4 different coloured skittles evenly spaced around the outside of the petri dish.
Hypothesis: I think that the water will dilute the Skittles and the colouring will start to come towards the middle.
The skittles are made of sugar and food colouring. As the Sugar dissolves the food colouring moves over the water with sugar until it cannot move any further because of the other colours
1.What questions arose in your mind as you did the activity?
How does this work?
Why do the skittles dilute from water?
2. what could you do to see if your ideas are correct?
Test it out.
Conclusion:
The water diluted the skittles and the colour started coming out and spreading.
