Walk Through Nature

This three-day workshop has been postponed. It had been scheduled for early July; the new dates are not yet known.

The arboretum and the UC Davis Art-Science Fusion Program planned the workshop together to teach others how they can successfully use art in science instruction.

In the Art-Science Fusion Program, students and community members create art projects around scientific themes. Many of these projects, ceramic mosaic murals in particular, can be seen in the arboretum and elsewhere on the campus.
