We have been following Climate change news in the media and newspapers.
The sculptor Mark Coreth has carved ice bears for display during the Climate change conference in Copenhagen. We are following the progress of the bears by web cam. One is placed in Copenhagen and the other one is standing in Trafalgar Square in London.
You can follow this link to see the bears:
We decided to have our own 'ice hare' project. We froze four ice hares and watched them as they melted.
Number 1 was the 'control.' It was made with plain water and we were not allowed to touch it.
Number 2 we were allowed to touch.
Number 3 was made of salty water and had food colouring added so that we could tell the difference.
