About the speaker

Ray Laurence

Brian Bennett is a High School Chemistry teacher in northern Indiana. After graduating in 2008, he moved to South Korea, where he started to question the effectiveness of traditional teaching methods. He found that teaching through ‘Flipped classrooms’ was much more successful, where traditional ‘lecturing’ is delivered outside the classroom, (often through online videos), while activities usually seen as homework are undertaken in the classroom under the guidance of a mentor. He has been an advocate of ‘flipped classrooms’ ever since.

 

 

 

The big issue

Remembering important laws of chemistry governing gases is as easy as ABC in this fun talk by Brian Bennett. What happens when you squeeze a sealed bottle with gas inside? Why do hot air balloons inflate? How can simply blowing into a balloon help you demonstrate Avogadro’s law? Brian Bennett answers all these questions and more.
