Third-grade classes of Rachel Peterson and Lisa Kutler, and fourth-grade class of Lacey Schweitzer were working on different projects, based on who the instructor was from the Taube.

Third-grade classes were putting together mobile sculptures, using a cube foam base, different colored wire and shapes that the students made out of paper.

Kutler’s class was making a stabile sculpture using the same materials.

The main difference between the two projects is that one is static, or still, and the other is dynamic, or moving.

The mobile sculpture got its name from the components on the piece that are movable. All components on a stabile sculpture are fixed in place and should not move.

Starting in the morning, three instructors from the Taube Museum collaborated with three classes during one hour, then moved on to another three classes after that. On Tuesday, there were only two instructors available for classes, so they did two classes in an hour, and continued the pattern until everyone had their chance to make a sculpture.
