Why we chose to do Dry Ice             

We chose to do dry ice because one of us (Morgan) did a similar project to this in grade 4 but that was small, it had a description of dry ice and what dry ice looks like, while she was presenting in front of the class the other one of us (Carlisle) was watching and thought that it was really cool, she wanted to learn more. Once it was time to do expo we decided to do dry ice to go further with our experimentation. It went very well!
