We walked from school to a local art studio - the Vitamin Art Studio (http://www.artvitamin.blogspot.com/). There were 3 artists there to help out and instruct the students. This was a good experience for the students because they got to walk around and make artwork in a working artists' studio. It was good for them to see how a professional artist works. This studio had 3 workstations set up, and I divided the students into 3 different groups. The students all got a chance to work at every station.
One station had still life objects set on a display with lights shining on it. Students were able to sit at drawing tables and practice observational drawing.
One station had a table covered in canvas. The giant canvas was divided into rectangles - 1 for each student. We were curious to see how one person's painting would influence the next groups.
Messy!
