Dada artists embraced chance, accident, and improvisation. Students generally lean more towards realism and technically based work in high school. This gives students a chance to get outside their comfort zone. Various approaches could be taken with this project. You could take the "cloud watching" approach and have students create random marks with paint or ink and then morph them into something. Or it could be left more abstract having students drop ink onto wet watercolor paper and just observe the reaction. (image by KinderArt)
Appropriation is the practice of creating a new work by taking a pre-existing image from another context--art history, advertising, the media—and combining that appropriated image with new ones.
High school students love stealing images. At this age students are completely wrapped up in trends, media, and commercialism. This is an interesting opportunity for students to consider advertisement, media and art within the same context.

I particularly like this topic for high school students because it can be taken in so many contexts. Students are free to interpret the word as they please, it could be an internal conflict, a home or school related conflict, or a conflict on a much larger scale. This idea also give students the opportunity to explore ways in which to convey an idea. Students need to consider whether a literal realistic representation conveys their message appropriately or if a surrealist or fantastical approach is better suited.
