What is boiling? An Introduction

What is boiling? An introduction to why water boils.
This video represents a proof of concept for the development of STEM learning resources collaboratively developed by students and a STEM expert (in this case Dr. B, a GHS teacher).
Video (0:00-0:15, 1:00-1:10), animation (the one with the green circle - 0:47 - 0:59), as well as research/script writing support, provided by students. Molecular simulations by Dr. B. using AtomSmith software.
The final version will contain student voice overs as well as Dr. B.
Boiling is a concept many students struggle with. Many believe the bubbles contain either air, H2 and O2 gases, or heat. Much of this is due to the difficulty visualizing the behavior of water molecules during boiling.
Additional videos (role of atmospheric pressure, vapor pressure, inter-molecular forces, etc. are currently being developed.
