We read the story "The Dot" so it went along with Vashti thinking she couldn't draw so she only made one black dot on her paper. We talked about how most people think black is void of all color but it's actually made up of all colors. I placed a black dot on the middle of a coffee filter and set the filter in the top of a cup of water. As the filter absorbed the water, the colors that make up black began to expand around the dot. We talked about Chromatography is the study of separating a mixture using a solution (the colors of black separated out as the filter absorbed the water). We made predictions about what would happen to the dot before we put it in the water and recorded our observations of the filters after we finished the experiment.
