Gases in the Air! 

Wow, what an exciting afternoon, spent at The Ladies College in the company of Dr Harrison.

We were asked to explore what we breathe in and then we looked at what gases we find in everyday objects. Lots of explosions and wow experiments that were used to capture our interest. 

We explored nitrogen and what happens when liquid nitrogen meets  air, which is 220 degrees hotter than this liquid.  We also learnt what would happen if our hands were placed in this dangerous substance. The flowers were a great hit 😉 and the reversible balloon! 

Another favourite gas we investigated was oxygen;  we even had a go at making oxygen like our fellow plants!! A messy experiment, but nether the less we did it.
