Moving Milk Mysteries

Every Friday we put on our lab coats and become scientists for the morning. We are learning how to make observations and predictions. For the next few weeks we are discovering how molecules behave. You can't see molecules but you can change them to observe their behaviour.

Last Friday we looked at molecules moving. We did this by colouring water molecules in some milk and then observing as we put drops of dishwashing liquid. We watched the water molecules getting moved around as the dishwash liquid collected up all the fat molecules.

Cool aye?

Then Luke C. asked "What if we used something else instead of milk?"

This Friday we tried cream, strawberry milk and oil.

The results? There was no reaction in the oil. This is because oil is all fat and no water. There was a VERY slow reaction in the cream. This is because there is very little water in the cream and not enough to be moved around easily. The strawberry milk had a reaction but the standard milk was the fastest. From our observations we could tell there was more fat in the strawberry milk than in the standard milk.




What will we find out next week?

Welcome to 2011!!!

Hey there everyone. Well it's back to school time again! Over the last couple of days I have been lucky enough to meet a whole heap of amazing children and their parents. We have a new class in Whanau Whitu and a new teacher!

I'm Tania and I have moved to Christchurch from Whangarei. I used to live here years ago and now I have come back so that my husband can study here at the university. I am so excited to be here and look forward to having an awesome year with a fantastic bunch of kids!

Today we learned about each other a little bit, and learned how to behave in the classroom. We had lots of fun and even had time for some art! We made name bugs. It was a test of our imaginations at first but we got the hang of it and they have turned out amazing!

Watch this space!
