Have children trace their hands on yellow construction paper and cut them out (they may need a little help). Glue the hands on the folded edge of a paper plate, as tail feathers. Have children cut out a yellow circle for the head and an orange triangle for the beak. They should glue these to the other end of the plate's folded edge. Draw two feet and photocopy on orange construction paper, with two thick stems for legs, glued on each inside flap of the open end, and bent outward later to allow the duck to stand.
Give each child a piece of construction paper to create a background for their flower. They begin by cutting a strip of green construction paper and gluing it to the bottom of the other sheet as grass. Help children glue a green pipe cleaner to the paper for a stem. Then, they cut two green circles and glue them next to the stem for leaves. Next, they cut a larger circle for the flower blossom and glue it at the top of the stem. Use white construction paper and color or paint it, or use yellow and call the flower a daffodil. Or, cut little crescent shapes along the outer edge of the circle to make it look more realistic. Each child receives one cup cut from an egg carton. Children can paint it if they choose. Glue the cup, with the rounded part making contact with the paper, in the center of the blossom to resemble a flower.
Each child receives a paper lunch bag and paints it blue. Set the bags aside to dry. Help children cut a long, 3-inch-wide rectangle out of blue construction paper. They then cut a couple of long slits in the rectangle. Wrap the base of the rectangle around a marker and tape the edges together to create a tube (this will be water coming from the whale's blow hole). Have children stuff newspaper in the paper bags, and wrap a rubber band around the bag, a couple of inches from the open edge, to resemble a tail. Poke a hole in one side of the bag and insert the blue construction paper spray into the hole, tube side down, and glue or tape in it place. Have children draw faces on their whales.
If the projects involve painting and gluing, you may need to allow for a little extra time for drying. Projects are always more interesting for kindergartners if you introduce a related story or song as well. Let the child do as much of the work as she can on her own. Even if the end results are sloppy, completing an art project builds confidence for small children. The process itself is often just as important as the end result.
