Science week

As part of science week Mrs Ryan used dry ice to do some experiments. Dry ice is made from a frozen gas called Carbon Dioxide.

It was so cold that ice had formed on the out side of the box.

Dry ice is so cold we could not touch it. 

Mrs Ryan put some dry ice into hot water

The dry ice quickly melted and turned back into Carbon Dioxide gas. 

We felt the gas and it felt cold.

Mrs Ryan then poured hot water into a bottle and added some dry ice.

Next she put a balloon over the top.

The carbon dioxide gas blew up the balloon.

The balloon got bigger

Then we tested which balloon was the heaviest, the one with air or  the one with Carbon Dioxide. 

We added food colour to see if the gas would change colour.

It didn't it stayed the same

Mrs Ryan tried to make a giant bubble with the gas

Lots of bubbles
