Rock Rollers President Jim Hutchings did a presentation at St. John's school in Roseville on October 4.
The classes were for 3rd & 6th graders. Jim conducted the classes, with the help of Frank Yoschak.
The students were working on a project about volcanoes.
Jim & Frank brought specimens for the students to look at.
The kids loved all the "hands-on" rocks!
One student shows a sample he brought from home.
