Super Cool Science

The community of Seabury school has so much to offer each other. Recently, one of our moms, an Evergreen State College professor, brought in some dry ice and some liquid nitrogen and did some super cool science experiments relating to the states of matter. 
We explored some of the properties of dry ice (frozen carbon dioxide) with its interesting property of sublimation, changing directly from a solid to a gas without becoming a liquid. 

We froze bubbles.

We listened to the reverberations it made
as it sublimated in a stainless steel bowl.
Chuckle, chuckle!

After being frozen with liquid nitrogen, we hammered nails with frozen bananas and cucumbers.

We tested rubber balls and found that the one frozen with liquid nitrogen became too dense to bounce.


We each got to freeze a flower in liquid nitrogen and then crumble up its petals:





We made and enjoyed liquid nitrogen frozen ice cream:



We eagerly watched as Ms Toska 
released the extra liquid nitrogen 
onto the playground:


Another super cool day of science spent as real scientists 
exploring, experiencing and discovering 
our world around us! 
Thank you, Toska, and your students Jasmine and Amanda!!
