We're so grateful to all the teachers for coming out. They all worked together.

A lot of teachers from elementary to university classes have been requesting ash samples through our Web site to do science projects. It's intriguing. From all over the United States, people are seizing the opportunity to do real-time studies of the volcano.

We tell them to get the kids a good breakfast, and enough sleep the night before.

We do things to motivate [the students]. It's a lot of pressure, and we try to make it easier for them.

Make a difference, change the game for the better, leave a legacy, be a guide that someone else can follow and make better, and then someone else will follow that and make that better.

That is the difference between good teachers and great teachers: good teachers make the best of a pupil's means; great teachers foresee a pupil's ends.
