KUSA - 9NEWS' science guy, Steve Spangler, is used to taking his students on field trips, but this time, his students are teachers and the adventure is a cruise along the inside passage of Alaska.

Steve was just outside of Juneau and gave 9NEWS viewers an up-close look at teachers teaching teachers.

And what happens when you put 76 science teachers on a cruise ship and point it toward Alaska? You quickly discover that Steve Spangler has created another unconventional way to get teachers excited about teaching science.

Before wrapping up his tour of southeast Alaska, Steve shared this update just outside Glacier Bay.
