You Will Need:
A trip to the beach, lake or creek, and supplies: plastic bottle, super glue, permanent marker, and a label
Have your child fill the bottle with sand and water from the beach, along with his favorite sea shells or small pieces of driftwood. Seal the top using super glue (keep the glue out of your child’s reach and let the bottle dry before using it with him). Label with the date and location of your outing.
At the beach, enjoy searching for “just the right” seashells. Ask your child, “Will a large one fit in your bottle?”; “How many do we need?”; “Could a fish live in your bottle?”; “How much sand do we need?”; “Where does the sand come from?”; “Is the sand the same at all beaches?”
Try to stay away from seaweed and other living plants, since they are perishable and will rot after a while. Or, set the expectation that you’ll have a “throw-away” bottle that can only be used for a set amount of time.
