Art is the meeting place of all subjects...  Art teacher know, when we grid, measure, and draw - we use geometry. When we make sculptures - we use engineering.  When we mix colors - we reveal information about physics.  When we create illustrations for stories - we learn about literature.  When we review the styles of art from da Vinci to Banksy - we teach history.  When we write about art - we strengthen these skills.  
When we create works of art, we solve complex visual problems in creative ways.  ~ Eric Gibbons.  ArtEdGuru.com
