Tin foil, yarn, cardboard, and sharpies. This makes a cool low relief sculpture. Start by teaching about line variations, and color schemes (monochromatic, analogous, etc.). Cool project for 6-7th grade.
Students created these wonderful snowmen in class. Students objective was to create a snowman with a fun (and Tall) hat. Students used markers to draw their snowman on the first day. On the Second day they used bright color paint to fill in the four equal squares of the background. The last part of the project was the best. Students dipped their fingers in white paint to add the snow.
