In 4^nd grade the Elements of Art that we are learning are Line and Space.

Our “Tornado” illusion Optical Art project was great fun. We started out by discussing how a “line” on a 2D piece of paper can give the illusion of a 3D object. The students then practiced the repeated curved line in a “sloppy copy” that gives the illusion and once they felt comfitable started the “real thing”. The students started with a dot in the center of the page and drew a line from the center to the edge of the page then filled each segment with curved lines to create the illusion of dimension. They then colored in the edges in colored pencils to further accentuate the depth of the shape.
