Aim:
I want to find out what happens when I put Skittles into water.
Method:
Equipment
- Skittles
- Petri Dish
- Warm water
- Beaker
- White background/surface
Instructions:
1.Get equipment
2.Put 8 Skittles in the petri dish.
3.Spread the Skittles out evenly on the petri dish.
4.Gently pour warm water in the middle of the petri dish.
5. Don't overflow the petri dish.
6. Observe and record on what happens.
Prediction:
I think I will see, colours spread out, and it will all be colourful and the Skittles will lose colour like it was bleached.
From this:
My thoughts were correct.
To This:
I saw the colours ran into each other, and spread out like it was a rainbow.
Discussion:
- The colours dissolved. Dissolve means when a solid mixes into a liquid creating a solution.
- The colour spread in the water. The colours were concentrated and diffused (Moved) to area there was no colour.
- The colours did not mix. The colours had different solubilities
