Milk

We are learning about milk.

After thinking about our prior knowledge and reading some information about where milk comes from and how milk can make other products we asked lots of questions. 

We are carrying out experiments to answer our questions. 

Is there water in milk? 

We heated the milk with a cold plate over the milk. When we tasted what was on the plate it was...WATER!

 The milk did some strange things like bubbling up in one big bubble and then going back down.

 We learnt that all milk is made up of 87% water and the other 13% has different substances depending on the kind of milk it is.

What makes different kinds of milk different?

 We are learning to observe like scientists and using our noticing muscles. 

 We compared different kinds of milk and noticed what colour they are, how they pour, how it tastes and what state it is in. 

One of things we noticed was some milk tasted fattier than others. We thought how they poured showed us how much fat was in each each kind of milk. 

We added dishwashing liquid which opens up the fat molecules in milk. The more fat in the milk the more it moved. The food colouring was just there so we could see the fat molecules open up and move. 

 "It's so weird watching all the colours move by themsleves".

 We used the microscope to find out what milk looks like really close up. We couldn't see the molecules because they are tiny but milk did look bubbly under the microscope.
