For notes today I had students draw the Phase change diagram into their notes. They seemed pleased to find out why dry ice is called "dry"
The lab today was to show how heating air expnads, increases air pressure, and can push a balloon up and off a flask. Then, when the air cools, it shrinks, creates a suction and pulls the balloon into the flask. This lab is on my website.
KIDS LOVE THIS LAB, IT KINDA SCARES THEM, AND THAT MAKES IT ALL THE BETTER.
I hope this helps,
Love to Teach and Teach with Passion!
It's not Magic, It's Science!
