Both children were given the same materials, and asked to make choices about: color mixing, art tool used, where they wanted to place their paint, how they wanted to explore the paper/base. They were also given the same amount of time, and no parental involvement.
All children were given the same materials- a mark making tool (to start they all used a paintbrush) and tempera paint. They were asked to paint on vertical mural paper, but make their own choices: would they use the paint color given or trade with a neighbor, paint with the tool given or trade for another, where would they choose to paint- up high, down low, in the corner.. they also chose if they wanted to mix colors and work together with another artist, or keep their color separate entirely. All children were given the same amount of time, and no parental involvement.
