Making butter

 Today for Science we made butter.  We put cream in jars and shook it until it thickened. 

 Then we tried it on crackers.  Some children thought it tasted like butter from the supermarket, some thought it tasted a bit like cheese. 

Dry ice

Yesterday we were very lucky because Kevin brought in some dry ice for us to look at.  He put it in water to make it bubble and used it to blow up a balloon.  He told us the balloon popped more loudly than a normal balloon because the sound travelled downwards.

Here are some of our stories about the dry ice:

Kevin and Roskill brought us some dry ice.  It was freezing.  He put it on our heads.  We got to touch it.  Roskill and Kevin came to our class.  They put the bowl on the carpet.  The balloon popped.

I see the dry ice.  It was cold.  The dry ice was on our head.

Kevin brought us ice.  Kevin brought us an experiment.  Kevin popped the balloon.

I like the bubbles from the experiment.  I missed some of the experiment.

Kevin and Roskill got a cup for the water.  I saw a bubble.  The bubble made my hand cold.
