CHILLY MILK EXPERIMENT:
PURPOSE: TO OBSERVE AND RECORD THE CHANGES WHEN DIFFERENT MILK IS PUT IN THE FREEZER.
WHAT YOU NEED: a selection of 3 different type of milk
WHAT TO DO: Put an equal volume of each type of milk in a clear container
Place each container in the freezer
Record what happens to each type of milk as it freezes. Note its colour,
texture and shape.
Record the time it takes to each variety to freeze.
Type of milk
what it looked like once it had frozen
Time taken to freeze
Whitish Creamy Runny
Yellowish - Whitish
Up & Go Milk
Chocolate - Brownish
The Result - We expected all three to freeze but we were surprised from the condensed milk from freezing. The up & go and soy milk froze. We questioned ourselves which one froze more. But we knew it was up & go because the water % was higher than the soy milk.
Conclusion - We learnt the ingredients in the condensed milk. Also we learnt why the condensed milk did not freeze. The reason why the condensed milk did not freeze is because there was more sugar and fat than water. If the condensed had more water it would have froze. But the up & go and soy milk froze.
Ingredients for condensed milk
Sugar - 41.0 %
Moisture - 31.0 %
Milk Sugar - 10.5 %
Fat - 8.0 %
Proteins - 8.0 %

The Science of milk
Aim: Can we get Water out of Milk?-Yes it can but it will evaporated.
Process: (type in what was used and what was done, in the order in which it was done)
frying pan, plate etc.
First the milk was put into the pan which was heating up and it started to create a kind of bubble.When the milk was hot the liquid in it was evaporating and it changed into a sort of Milk powder.
Prediction: what do you think will happen and why?-Yes it comes from a living source which is the cow.
Method: what do you think made the changes happen?-The liquid became smaller and smaller because of the heat and it causes it to become dry. The water had evaporated.
