Dock Piling Mural
One way to summarize what the children have learned is to draw a sketch of a dock piling on the bulletin board or chalk board. Or make paper constructions that are the size and shape of two dock pilings. Label one dock piling "High Tide" and the other "Low tide." The children can draw pictures or make paper constructions of seaweeds and animals at high tide and at low tide, and place these on the appropriate dock piling.
Write or tell a story about the life of a favorite seashore animal that takes place over the tidal cycle. What happens at high tide, ebb tide (when the tide turns), and at low tide? Draw a picture of the animal at high tide and at low tide. (See page 263 for creative writing ideas).
Cut an old piece of cloth into long strips to resemble seaweeds. Ask for two children to dip the cloth strips in water and arrange the strips in a pile (if possible on a cobblestone), as if the strips were Rockweeds on a rock or bull Kelp stranded on the shore. Ask for several volunteers to come to the front of the class and feel the wetness of the seaweeds. Ask for other volunteers to come up wand dry the seaweed pile using the hair dryer. They are not allowed to move the strips of cloth. Tell the class to imagine that the hair dryer is the sun. After ten minutes, discuss the following: Would a person's hair be dry by now? Why does the outside of the pile become dry, but not the inside? How is the pile of strips like kelp stranded on the beach? Why do so many shoreline animals hide among seaweeds at low tide? Why did Rachel Carson refer to the Rockweeds as a "seaweed nursery?"
