First students chose whether they would use warm colors for the sky or for the water. The opposite colors (cool) were used for the space not filled by warm colors. Scrap construction paper was torn into short to medium strips of color and glue horizontally across the space.
Black paper was used to draw and cut out at least two ships in two different sizes to glue onto the water to show space by placing the larger boat up front and a smaller boat nearer to the horizon line.
