Get a large magnifying glass and let the children look at sea shells with it. They will be impressed with the make-up of sea shells Make a paper mache or clay volcano around a small cup. You can then make the Volcano erupt with vinegar and baking soda (add food coloring to make the lava look more real)
Tip: To make it look more real cover the volcano with small pebbles and dirt Place several shells and sand along with a magnifying glass in an area of your classroom. Your children will love getting to see the patterns and makeup of these items. Put seaweed (purchase from the grocery store) in your water table. This makes the area smell like the sea. The seaweed also feels like the real thing. Fill a plastic soda bottle half way with blue died water. Next fill the remainder of the bottle with oil Now your children can make waves by tilting the bottle.
