Mixing dish soap and milk.

Aim:  What will happen if you mix full fat milk and dish washing liquid together?


Hypothisis: Milk and dish soap is like water and oil, it will not mix together. Dish washing liquid is made to clean and erase fat from your dirty and greecy dishes. With that said the dish washing liquid will try to seperate the fat from the milk.


Equitment:

• A wide plate
• A few cottonbuds
• Full fat milk
• Dish washing liquid
• Food coluoring. 

Method:  When we did this experiment we had to do 3 steps.

Step 1, pour the milk into your wide plate until it fills the whole plate.

Step 2, Put drops of different food colours.

Then put some dish washing liquid onto your cotton bud.

Step 3, then dip your cotton bud into the plate.

Observation:

When we dipped the cotton bud into the milk we saw the food colouring move to the side of the plate, as if it was running away from the cotton bud.

Conclusion: This happened because the dish washing liquid separated the fat from the milk, so we saw the milk separating or moving as this was happening.
