Science - inquiry about matter and changes of state

We are learning all about matter and changes of state

Our first inquiry idea is that water can exist in 3 states: solid, liquid, or gas.

Mrs Bertrand asked the children in Ruma Piwakawaka:

What do you know about water?

Here is what we know:

Charlotte - water is heavy

Zach - it's wavy

Alanna - it is light blue

Anja - you can't hold it

Noah -  it's cold

Charlotte - some water is hot

Harry - some water is hot, like hot water beach

Harry - steam is actually water

Tui - you can heat water in a jug

Alanna - if you put it in the freezer it will turn to ice

Harry - steam can turn into a cloud

Wow...we already know so much about water!

Then we took some water and we tried to pour it into our hands to hold it.

Do you think this worked??

No.  The water flowed right through our hands and we couldn't hold it.

We said this happened because it is a liquid.

Next we got an ice cream container and filled it with water (a liquid).

We put it in the freezer.

The next day we took it out, and it was frozen into a solid.

We put a plastic pig in the big ice block so we could see what happens when it melts.

The solid ice slowly started melting.

When the sun came out we saw the ice melting faster.

It took 3 hours for our big ice block to completely melt away.

Some of us said - where is the water????

What do you think happened to the water?
