Designed by Carol Sconyers Twice each day the ocean waters rise along the shores and twice each day they fall. This constant rising and falling is called the tide. When the water retreats from the land’s edge, it leaves little pockets of water teeming with sea life. The tide pool offers us our first contact with mysteries of the sea. One of the most common sights in the tide pool is the starfish. They may be seen hanging on rocks when the tide goes out. They come in a wide variety of sizes and colors, but are always star-shaped. Most starfish have 5 arms but some have as many as twelve. Shellfish are their main food. Their mouth is on the underside, in the middle. Each arm on the Starfish has a foot on the end; and each foot has a sucker like suction cup that helps them stick to rocks and catch their food. Using their suckers, they pull open the shell of shellfish and they push their stomach inside the shell and slowly digest the clam or oyster right on the spot. Starfish don’t have eyes, they have an eyespot on the tip of each arm. Starfish breathe through their feet. Truly, the starfish is an amazing animal. Educational Objectives: This lesson provides opportunities for students to: ·Learn how to pinch and pull clay from a chunk of clay. ·Learn to push and pull the clay to form a starfish.
