Milk Experiment

This Picture is the three type of milk my group have chosen  to experiment on!!! 


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
*clear container


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 been freezed.
Time
taken to freeze
UP & GO
Icy, the colour went kind of darker.
It took over night.
CONDENSED MILK
I looks the same. ( GOEY )
Not sure because it is still not frozen
ALMOND MILK
It looked icy, ( WHITE ICE )
did not look like milk at all.
It took over night


UP & GO PREDICTION :
With the Up & Go our prediction is that it'll go kind of flaky/icy
The colour will go lighter so will the texture and the shape will be round, depending on the shape of the container or cup.
TIME : 30 - 35 MINS


CONDENSED MILK PREDICTION :
We think that it’ll freeze slowly because of how goey it is, or it might just be icy cold.
The colour will kind of stay the same so as the texture & the shape will just be goey and round because of the cup it is in. But then it might only be the top that freezes,and the inside it’ll just be icy cold and goey.
TIME : 30-55 MINS


ALMOND MILK PREDICTION :
We think that the almond milk will freeze, but it’ll kind of take it’s time. W sa that the colour will stay the same or look a bit watery.  The texture would look the same and the shape would be round/circle.
TIME : 30 - 23 MINS

QUESTIONS :
***
  1. What ingredients are in CONDENSED MILK ?!?!
ANSWER
- Moisture : 31.0 PERCENT.
- Sugar ( sucrose ) : 41.0  PERCENT
- Milk Sugar ( lactose ) : 10.5 PERCENT
- Fat : 8.0 PERCENT
- Proteins : 8.0 PERCENT
- Ash : 1.5 PERCENT


  1. Why doesn’t CONDENSED MILK freeze ?
ANSWER : because theres no water in it...
( Cause all the water has been taken out of it.)


  1. How much water is in UP & GO - ALMOND MILK & CONDENSED MILK
***
ANSWER - UP & GO :  


ANSWER - CONDENSED MILK : 31.0 PERCENT


ANSWER - ALMOND MILK :

CONCLUSION OF THIS EXPERIMENT :
I've learnt that condensed milk couldn't freeze because it hardly have water in it. To have something frozen it normally have water in it to make it freeze easily. It depends on the amount of water they have in it. If it barely have water like condensed milk then it take time to froze. Also that's why almond milk and up&go froze easily because of the amount of water they have in it. Condensed milk couldn't freeze over night because it barely have water in it. So condensed milk is more likely to take more then one night/day to freeze.!!!

Solid can be turned into liquid!!
